Study Objectives: To determine whether sleep disruption increases ventricular ectopy and the risk of cardiac arrest in hospitalized patients. Methods: Hospital emergency codes (HEC) trigger multiple hospital-wide overhead announcements. In 2014 an electronic “code white” program was instituted to protect staff from violent patients. This resulted in an increase in nocturnal HEC. Telemetry data was examined between September 14 and October 2, 2014. The frequency of nocturnal announcements was correlated with changes in frequency of premature ventricular complexes per hour (PVC/h). Cardiac arrest data were examined over a 3-y period. All HEC were assumed to have triggered announcements. The relationship between nocturnal HEC and the incidence of subsequent cardiac arrest was examined. Results: 2,603 hours of telemetry were analyzed in 87 patients. During nights with two or fewer announcements, PVC/h decreased 33% and remained 30% lower the next day. On nights with four or more announcements, PVC/h increased 23% (P < 0.001) and further increased 85% the next day (P = 0.001). In 2014, following the introduction of the code white program, the frequency of all HEC increased from 1.1/day to 6.2/day (P < 0.05). The frequency of cardiac arrest/24 h rose from 0.46/day in 2012–2013 to 0.62/day in 2014 (P = 0.001). During daytime hours (06:00–22:00), from 2012 through 2014, the frequency of cardiac arrest following zero, one or at least two nocturnal HEC were 0.331 ± 0.03, 0.396 ± 0.04 and 0.471 ± 0.09 respectively (R2 = 0.99, P = 0.03). Conclusions: Sleep disruption is associated with increased ventricular ectopy and increased frequency of cardiac arrest. Citation: Miner SE, Pahal D, Nichols L, Darwood A, Nield LE, Wulffart Z.

Objectives Links between arrhythmias and particulate matter exposures have been found among sensitive populations. We examined the relationship between personal PM2.5 (particulate matter ≤ 2.5μm aerodynamic diameter) exposures and ectopy in a panel study of healthy welders. Methods Simultaneous ambulatory electrocardiogram (ECG) and personal PM2.5 exposure monitoring with DustTrak™ Aerosol Monitor was performed on 72 males during work and non-work periods for 5–90 hours (median 40 hours). ECGs were summarized hourly for supraventricular ectopy (SVE) and ventricular ectopy (VE). PM2.5 exposures both work and non-work periods were averaged hourly with lags from 0- to 7-hours. Generalized linear mixed-effects models with a random participant intercept were used to examine the relationship between PM2.5 exposure and the odds of SVE or VE. Sensitivity analyses were performed to assess whether relationships differed by work period and current smokers. Results Participants had a mean(SD) age of 38(11) years and were monitored over 2,993 person-hours. The number of hourly ectopic events was highly skewed with mean(sd) of 14(69) VE and 1(4) SVE. We found marginally significant increases in VE with PM2.5 exposures in the 6th and 7th hour lags, yet no association with SVE. For every 100μg/m3 increase in 6th hour lagged PM2.5, the adjusted OR(95% CI) for VE was 1.03(1.00, 1.05). Results persisted in work or non-work exposure periods and non-smokers had increased odds of VE associated with PM2.5 as compared to smokers. Conclusions A small increase in the odds of ventricular ectopy with short term PM2.5 exposure was observed among relatively healthy men with environmental and occupational exposures. PMID:27052768

To identify potential new markers for assessing the risk of sudden arrhythmic events based on a method that captures features of premature ventricular complexes (PVCs) in relation to sinus RR intervals in Holter recordings (heartprint). Holter recordings obtained 6 weeks after acute myocardial infarction from 227 patients with reduced ventricular function (left ventricular ejection fraction ≤ 40%) were used to produce heartprints. Measured indices were: PVCs per hour, standard deviation of coupling interval (SDCI), and the number of occurrences of the most prevalent form of PVCs (SNIB). Predictive values, survival analysis, and Cox regression with adjustment for clinical variables were performed based on primary endpoint, defined as an electrocardiogram-documented fatal or near-fatal arrhythmic event, death from any cause, and cardiac death. High ectopy (PVCs per hour ≥10) was a predictor of all endpoints. Repeating forms of PVCs (SNIB ≥ 83) was a predictor of primary endpoint, hazard ratio = 3.5 (1.3-9.5), and all-cause death, hazard ratio = 2.8 (1.1-7.3), but not cardiac death. SDCI ≤ 80 ms was a predictor of all-cause death and cardiac death, but not of primary endpoint. High ectopy, prevalence of repeating forms of PVCs, and low coupling interval variability are potentially useful risk markers of fatal or near-fatal arrhythmias after myocardial infarction.

Solitary metastases after surgically-treated cervical cancer are a rare entity, with only few cases described so far. We present the case of a 31-year-old patient diagnosed with a tumoral splenic lesion at 18 months after surgically-treated cervical cancer. The patient was submitted to surgery, with a splenectomy being performed. The histopathological studies confirmed the presence of a squamous cell cervical cancer splenic metastasis. At one year follow-up after splenectomy, the patient is free of any recurrent disease. Solitary splenic metastases after surgically-treated cervical cancer are rarely seen; however, this diagnostic should not be omitted whenever a medical history of cervical cancer is present.

Estrogen contributes to the onset, persistence, and malignant progression of cervical cancer in a human papillomavirus-transgenic mouse model

PubMed Central

Cervical cancer is a leading cause of death by cancer among women worldwide. High-risk human papillomaviruses (HPVs) are the major etiological agents for cervical cancer, but other factors likely contribute to cervical cancer, because these cancers commonly arise decades after initial exposure to HPV. Estrogen is thought to be one such cofactor; however, its temporal requirements in human cervical cancer are not known. Here we evaluate the temporal requirements of estrogen in cervical carcinogenesis in a mouse model for HPV-associated cervical cancer. Tumors arising in HPV16 transgenic mice treated with estrogen for 9 months were greatly increased in their size compared with tumors developing after 6 months of estrogen treatment. HPV16 transgenic mice treated 6 months with estrogen followed by 3 months without exogenous estrogen had significantly fewer tumors and the tumors were smaller and less aggressive than those arising in mice treated the full 9 months. Importantly, cervical cancers that arose in the mice treated the first 6 of 9 months with estrogen must have regressed, based upon the reduced incidence of cancers in these mice compared with those treated for 6 months with estrogen, then immediately analyzed. We conclude that estrogen plays a critical role not only in the genesis of cervical cancer but also in its persistence and continued development in this mouse model. These findings raise the clinically relevant possibility that, if human cervical cancer has a similar dependence on estrogen for continued tumor growth, then antiestrogen therapy may be effective in the treatment of cervical cancer.

This study was aimed at 1) reporting cases of missed cervical spine injuries treated at a tertiary-level hospital, King Faisal Hospital, Rwanda (KFH-R), and 2) identifying the causes of delaying the diagnosis. We prospectively collected data from patients with a missed or delayed cervical spine and/or cord injury treated at King Faisal Hospital, Kigali for a 12-month period (January 2012 to December 2012). The total number of cervical spine injury patients treated at our center was retrieved from the hospital admission registry. Forty-two patients with cervical spine or spinal cord injuries were treated at KFH-R in 2012, and 4 of them had a missed or delayed diagnosis. Clinical and radiologic findings of all 4 patients are presented, and the reasons for delaying diagnosis are identified. This study found that the cervical spine injuries were missed in 9.5% of the cervical spine trauma patients and resulted in a longer hospital stay for all 4 patients and severe disability in 1 patient (25%). The reasons for missed diagnoses in this study were 1) lack of cervical spine radiographic evaluation, 2) inadequate cervical spine radiographs to show the level of injury, 3) poor sensitivity of cervical spine plain radiography, 4) poor physical examination, 5) the presence of a distracting injury, and 6) poor sensitivity of radiographs and computed tomography scans for soft tissue injuries.

To observe the effect of Cuichan Zhusheng Decoction (CZD) on cervical maturation factors. Ninety women with full-term pregnancy and indication for labor inducing were assigned to three groups equally. The treated group was treated by water decoction of CZD, one dose (300 mL) daily, taken orally in the morning 30 min before breakfast, for successive 3 days, the administration would be discontinued if uterine contraction occurred for over 3 times/hour in the course. The control group was treated with pitocin by adding 1 U into 500 mL 5% glucose for intravenous dripping in 6 h, once every day for 3 successive days. The blank group was treated by placebo of CZD, administrated in same way as that in the treated group. The length and width of cervix and diameter of neck tube in all the women were measured on the very day of medication and 72 h later or parturient time by vaginal B-ultrasonography, and the cervical maturation degree was scored referring to the clinical Bishop scale. In the experimental study, the cervical tension of pregnant rats was measured with an in vitro cervical tension-meter, rats' cervical tissues were taken for pathologic examination to observe its morphological change. The total effective rate for promoting cervical maturation was 96.67% in the treated group and 83.33% in the control group. It was significantly superior in the treated group to that in the control group and the blank group (P<0.05). Moreover, the cervical score in the treated group was higher in comparing with that in the blank group showing statistical significance (P<0.05). Animal experiments displayed that after medication, the cervical tissue of rat loosened with significantly lessened, swollen, convoluted and ruptured collagen fiber, showing sparse disorderly lined-up reticular status. Degradation of collagen fiber, vascular dilatation and congestion with massive amount of inflammatory cells infiltration, increased matrix components, and many leucocyte and fibroblast in the stroma could be seen. CZD can change the morphorlogic structure of cervical tissue, decrease cervical tension, so as to promote the cervical maturation and induce labor.

Ectopic thyroid tissue remains a rare developmental abnormality involving defective or aberrant embryogenesis of the thyroid gland during its passage from the floor of the primitive foregut to its usual final position in pre-tracheal region of the neck. Its specific prevalence accounts about 1 case per 100.000-300.000 persons and one in 4.000-8.000 patients with thyroid disease show this condition. The cause of this defect is not fully known. Despite genetic factors have been associated with thyroid gland morphogenesis and differentiation, just recently some mutation has been associated with human thyroid ectopy. Lingual region in the most common site of thyroid ectopy but ectopic thyroid tissue were found in other head and neck locations. Nevertheless, aberrant ectopic thyroid tissue has been found in other places distant from the neck region. Ectopic tissue is affected by different pathological changes that occur in the normal eutopic thyroid. Patients may present insidiously or as an emergency. Diagnostic management of thyroid ectopy is performed by radionuclide thyroid imaging, ultrasonography, CT scan, MRI, biopsy and thyroid function tests. Asymptomatic euthyroid patients with ectopic thyroid do not usually require therapy but are kept under observation. For those with symptoms, treatment depends on size of the gland, nature of symptoms, thyroid function status and histological findings. Surgical excision is often required as treatment for this condition. Copyright © 2014 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

Beta1-receptor antagonists (BBs) are commonly administered in the treatment of cardiovascular disease (CVD). The reported benefits of BB use in CVD patients with concomitant obstructive sleep apnea (OSA) may be limited by their impact on apnea-induced bradycardias. Therefore the aim of the study was to test the influence of BBs on periapneic heart rate (HR) fluctuations in hypertensive patients with newly-detected and untreated OSA. We studied 88 hypertensive patients (56 on BBs and 32 BB naive) with newly-diagnosed moderate-to-severe OSA who were free of major pulmonary comorbidities and did not require antiarrhythmic therapy. ECGs recorded during sleep were investigated for heart rate (HR) responses to apneas allowing to compare extreme HR accelerations and decelerations between the groups. Average sleep-time HR was comparable in BB-naive (BB-) and BB-treated (BB+) patients. Direct comparisons showed that HR decelerations were also similar in the two subgroups (53.8±9.6 vs. 54.4±7.8 bpm; P=0.78, for BB- and BB+, respectively) however, BBs blunted the OSA-induced HR accelerations (82.3±12.2 vs. 74.3±10.0; P=0.003). After adjusting for baseline HR and magnitude of desaturations, HR decelerations were more evident in BB-naive group whereas tachycardic responses remained blunted in the BB+ group. The incidence of ectopies and conduction abnormalities were comparable across two groups. Beta-blockers do not potentiate apnea-induced HR decelerations, attenuate apnea-induced increases in heart rate and do not influence incidence of ectopies and conduction abnormalities in patients with hypertension and moderate-to-severe, untreated OSA.

The aim of the study was to assess the effectiveness of pharmacotherapy and physiotherapy in cervical vertigo treatment. 80 patients with cervical vertigo (41 women and 39 men), aged 20 to 85, were treated by pharmacotherapy or physiotherapy. There were two groups: group I was treated by pharmacotherapy and group II was treated by physiotherapy and kinesitherapy. The effects of vertigo treatment were assessed by positional nystagmus testing according to Cawthorne and Rosen; cervical nystagmus testing in neck rotation test; by everyday task self-control cards and vertigo staging system according to Silvoniemi (0-4 points). The effects of treatment were assessed before therapy, 6 and 12 weeks after therapy. Patients from group I were treated by Nootropil and Betaserc; group II received magnetic Fidel, laserotherapy, massage and kinesitherapy exercises. The obtained results showed that the most useful methods of cervical vertigo diagnosis were neck rotation test and Rose method. The average number of points (according to Silvoniemi scale) on the basis of ten everyday activities, was lower after 6 weeks of treatment than before the treatment and the lowest after 12 weeks of treatment. The difference was higher in group II than in group I. Patients treated by physiotherapy (group II) performed better in everyday activities than the patients treated by pharmacotherapy (group I). Cervical vertigo treatment by physiotherapy is cheap and underestimated method.

Surgical treatment for severe circumferentially fixed cervical kyphosis has been challenging. Both anterior and posterior releases are necessary to provide the cervical mobility necessary for fusion in a corrected position. In two case reports, we describe the circumferential osteotomy of anterior-posterior-anterior surgical sequence, and the efficacy of this technique when cervical pedicle screw fixation for severe fixed cervical kyphosis is used. Etiology of fixed cervical kyphosis was unknown in one patient and neurofibromatosis in one patient. Both patients had severe fixed cervical kyphosis as determined by cervical radiographs and underwent circumferential osteotomy and fixation via an anterior-posterior-anterior surgical sequence and correction of kyphosis by pedicle screw fixation. Severe fixed cervical kyphosis was treated successfully by the use of circumferential osteotomy and pedicle screw fixation. The surgical sequence described in this report is a reasonable approach for severe circumferentially fixed cervical kyphosis and short segment fixation can be achieved using pedicle screws.

Cervical interfacet spacers and maintenance of cervical lordosis.

PubMed

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). There was no significant difference in the Ishihara index (5.76 preoperatively and 6.17 postoperatively, p = 0.8037). The analysis had 80% power to detect a change of 4.25 in the Ishihara index at p = 0.05. There was no significant difference in the preand postoperative cervical lordotic angles (35.6° preoperatively and 33.6° postoperatively, p = 0.2678). The analysis had 80% power to detect a 7° change in the cervical lordotic angle at p = 0.05. The ANOVA of the Ishihara index and cervical lordotic angle did not show a statistically significant difference in degree of change in cervical lordosis among patients with a different number of levels of CIS insertion (p = 0.25 and p = 0.96, respectively). CONCLUSIONS In the authors' experience of placing CISs in more than 100 levels, they found no evidence of significant loss of cervical lordosis. The long-term impacts of these implants on fusion rates and clinical outcomes (particularly radiculopathy and postoperative C-5 palsies) remain active areas of interest and fertile ground for further studies.

Targeting Stable Rotors to Treat Atrial Fibrillation.

PubMed

Narayan, Sanjiv M; Krummen, David E

2012-09-01

Therapy for atrial fibrillation (AF) remains suboptimal, in large part because its mechanisms are unclear. While pulmonary vein ectopy may trigger AF, it remains uncertain how AF, once triggered, is actually sustained. Recent discoveries show that human AF is maintained by a small number of rotors or focal sources. AF sources are widely distributed in patient-specific locations, often remote from pulmonary veins and in the right atrium and stable for prolonged periods of time. In a multicentre experience, brief targeted ablation at sources (focal impulse and rotor modulation [FIRM]) terminated AF predominantly to sinus rhythm prior to pulmonary vein isolation and eliminated AF on rigorous followup. This review summarises the evidence for stable rotors and focal sources of human AF and their clinical role as ablation targets to eliminate paroxysmal, persistent and long-standing persistent AF.

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

Temporomandibular dysfunction (TMD) is considered to be associated with imbalance of the whole body. This study aimed to evaluate the influence of TMD therapy on cervical spine range of movement (ROM) and reduction of spinal pain. The study group consisted of 60 patients with TMD, cervical spine pain, and limited cervical spine range of movements. Subjects were interviewed by a questionnaire about symptoms of TMD and neck pain and had also masticatory motor system physically examined (according to RDC-TMD) and analysed by JMA ultrasound device. The cervical spine motion was analysed using an MCS device. Subjects were randomly admitted to two groups, treated and control. Patients from the treated group were treated with an occlusal splint. Patients from control group were ordered to self-control parafunctional habits. Subsequent examinations were planned in both groups 3 weeks and 3 months after treatment was introduced. The results of tests performed 3 months after the beginning of occlusal splint therapy showed a significant improvement in TMJ function (P > 0.05), cervical spine ROM, and a reduction of spinal pain. The conclusion is that there is a significant association between TMD treatment and reduction of cervical spine pain, as far as improvement of cervical spine mobility. PMID:25050363

Cervical epidural steroid injections, administered either interlaminarly or transforaminally, are common injection therapies used in many interventional pain management practices to treat cervicalgia or cervicobrachial pain secondary to spondylosis or intervertebral disc displacement of the cervical spine. Among the risks associated with these procedures are the risk for inadvertent dural puncture and the development of positional headache from intracranial hypotension. We report the case of a 31-year-old woman with a history of migraine and cervicalgia from cervical spine spondylosis and cervical disc degenerative disease that developed an intractable orthostatic headache accompanied by nausea and vomiting after a therapeutic high cervical intralaminar epidural steroid injection was administered directly to the C1-C2 spinal level. Although the initial magnetic resonance imaging of the brain was unremarkable, a computed tomography myelogram study revealed a massive cerebrospinal fluid (CSF) leak from the cervical spine.  Repeated cervical epidural blood patches using a catheter targeted to the high cervical spine (C2) to inject 15 mL of autologous blood was required to totally alleviate her symptoms after she failed conservative therapy. Determining the optimal location or approach to administer an epidural blood patch can be a challenge depending on the location of the CSF leak. Our case demonstrates that targeted cervical epidural blood patch placement using an easily manipulated catheter under fluoroscopic guidance is a safe and effective approach to treat a massive CSF leak in the high cervical spine region caused by prior therapeutic cervical spine epidural steroid injection.

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 < 0.01). In group B, cervical anteflexion showed significant difference at the 13th day after treatment (P < 0.05), but at the 1 month after treatment, the significant difference disappeared (P > 0.05); cervical extension showed significant difference at the 7th day after treatment compared with the beginning (P < 0.05). Compared with the beginning,left lateral bending showed significant difference at the 1st day after treatment in group A (P < 0.05) and at the 5th day after treatment in group B (P < 0.01). Both in group A or B, right lateral bending, left and right rotative activity showed significant difference at the same time after treatment, either the 3rd day (P < 0.05) or the 5th day (P < 0.05). Compared between groups, cervical anteflexion, left and right lateral bending, left and right rotative activity showed significant difference at the 1 month after treatment (P < 0.05). The rotation-traction manipulation and neck 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.

To explore the clinical characteristics and new treatment for syndrome of craniocerebral-cervical vertebral injury. The clinical data of 52 patients with head injury accompanied by neck injury were analyzed retrospectively. Craniocerebral injury could result in damage to cervical vertebrae, muscles, vessels and nerves, and even cause vertebral artery injury, which may lead to insufficient blood-supply of vertebral-basal artery. All patients were treated with cervical vertebral traction and the results were good. Acute craniocerebral injury with symptom of insufficient blood-supply of vertebral-basal artery, evident neurosis and atlas-axis half-dislocation in X-ray should be treated by cervical vertebral traction, which will yield better outcome.

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

Single-level cervical radiculopathy may be treated conservatively with cervical tractions. Posterior cervical transfacet fusion with a facetal spacer is a viable option. The aim of the present study is to compare posterior cervical transfacet fusion with conservative physical treatment in single-level cervical radiculopathy. A total of 80 patients were randomized in 2 groups, a surgical group in which patients were given posterior cervical transfacet fusion and a traction group in which patients were treated conservatively with mechanical cervical tractions. Visual analog scale for arm and neck, Neck Disability Index, and Short Form-36 (SF-36) questionnaires were administered preoperatively and after treatment up to 12 months. After treatment, visual analog scale arm scores were greater in traction group (4.7 vs. 1.5 the day after treatment) and at follow-up controls (traction group vs. surgical group: 5.3 vs. 0.6 at 1 month, 3.6 vs. 0.3 at 6 months, 1.8 vs. 0.2 at 12 months). Neck Disability Index scores were lower in the surgical group (surgical group vs. traction group: 4.4 vs. 20.3 at 1 month, 1.3 vs. 10.5 at 6 months). SF-36 scores were greater in the surgical group (surgical group vs. traction group: 96 vs. 70 at 1 month, 96.5 vs. 82.6 at 6 months). Neck disability index and SF-36 scores were superimposable between the groups at 12-month follow-up. No adjacent-segment arthrosis or late complications were reported at 1-year follow-up in the surgical group. posterior cervical transfacet fusion is a safe and effective procedure to treat single-level cervical radiculopathy.

Data on immune mediators in the genital tract and the factors that modulate them in sub-Saharan women are limited. Cervicovaginal lavage (CVL) samples from 430 sexually active women from Kenya, South Africa, and Rwanda were analyzed for 12 soluble immune mediators using Bio-Plex and Meso Scale Discovery multiplex platforms, as well as single enzyme-linked immunosorbent assays. Ten bacterial species were quantified in vaginal swab samples. Bacterial vaginosis (BV) was defined by Nugent scoring. CVL samples from HIV-infected women showed a clear-cut proinflammatory profile. Pregnant women, adolescents, and women engaging in traditional vaginal practices differed in specific soluble markers compared to reference groups of adult HIV-negative women. Cervical mucus, cervical ectopy, abnormal vaginal discharge, and having multiple sex partners were each associated with an increase in inflammatory mediators. The levels of interleukin-1α (IL-1α), IL-1β, IL-6, IL-12(p70), and IL-8 were elevated, whereas the IL-1RA/IL-1(α+β) ratio decreased in women with BV. The level of gamma interferon-induced protein 10 was lower in BV-positive than in BV-negative women, suggesting its suppression as a potential immune evasion mechanism by BV-associated bacteria. Lactobacillus crispatus and Lactobacillus vaginalis were associated with decreased proinflammatory cytokines and each BV-associated species with increased proinflammatory cytokines. Remarkably, the in vitro anti-HIV activity of CVL samples from BV-positive women was stronger than that of BV-negative women. In conclusion, we found significant associations of factors, including vaginal microbiota, which can influence immune mediators in the vaginal environment in sexually active women. These factors need to be considered when establishing normative levels or pathogenic cutoffs of biomarkers of inflammation and associated risks in African women.

Although the existing evidence suggests that there is no obviously superior conservative method for treating cervical intraepithelial neoplasia (CIN), one of the most widely used is the large loop excision of the transformation zone (LLETZ). A total of 897 women who were treated with LLETZ at our colposcopy clinic from 1989 to 2000 were retrospectively studied. Forty women did not have significant cervical pathology (4.5% over-treatment rate). Clear margins of excision were obtained in 748 (88.5%) of the 845 cases of CIN or microinvasive cancers. Treatment failure rates were 4.7% for clear margins and 26.8% for involved or uncertain. LLETZ is a fast and reliable method of treating CIN and microinvasive carcinoma. Generalized cauterization of the resulting crater should be avoided and satellite HPV lesions ablated. Involved margins have a higher treatmentfailure rate, therefore a larger excision is recommended as cervical craters regenerate. Treatment in pregnant women can be delayed until postpartum provided they have adequate surveillance during pregnancy.

Complications of Anterior and Posterior Cervical Spine Surgery

Cervical spine surgery performed for the correct indications yields good results. However, surgeons need to be mindful of the many possible pitfalls. Complications may occur starting from the anaesthestic procedure and patient positioning to dura exposure and instrumentation. This review examines specific complications related to anterior and posterior cervical spine surgery, discusses their causes and considers methods to prevent or treat them. In general, avoiding complications is best achieved with meticulous preoperative analysis of the pathology, good patient selection for a specific procedure and careful execution of the surgery. Cervical spine surgery is usually effective in treating most pathologies and only a reasonable complication rate exists. PMID:27114784

This case report of a 36-year-old woman with a diagnosis of cervical pregnancy describes a novel approach to this rare form of ectopic pregnancy, which was successfully treated with systemic and local methotrexate (MTX) therapy combined with hysteroscopic resection. After local and systemic administration of MTX, the patient underwent hysteroscopic resection of the cervical pregnancy using a 27 bipolar resectoscope with a 4-mm loop. The cervical pregnancy was completely treated, and satisfactory hemostasis was achieved with electrocoagulation. The reported case and literature review demonstrate that the combination of systemic and local (hysteroscopic) administration of MTX with hysteroscopic resection could offer the possibility of a safe, successful, minimally invasive, and fertility-sparing surgical treatment for cervical pregnancy.

Congenital hydronephrosis caused by ureteral anomalies, like ureteral duplicity, megaureter, ureteral ectopy and ureterocele, must be differentiated from ureteropelvic junction obstruction (UJO) hydronephrosis and from the hydronephrosis caused by vesicoureteral reflux. These represent a differentiated branch of congenital abnormalities in children even if not so common, but this fact should not be disconsidered. Over a five years period, from 111 operated children in our Clinic, we performed 13 interventions for congenital hydronephrosis, 11 (84.61%) being caused by ureteral abnormalities. Here, there were described particular cases, with diagnosis steps and treatment decisions. Ureteral ectopy can be manifested by loss of urine drops in cases where ureteral holes are located in the vagina, septum or urethra, inferior to the sphincter mechanism. Incontinence in boys never occurs because the ectopic ureter never opens under the sphincter mechanism. If the ureter opens in the genital tract, patients may clinically present with the epididymitis symptom. From autopsy statistics in the US, the incidence of ureteral duplex is estimated to be less than 1%. When the duplex is associated with urinary infection, the incidence of ureteral duplex increases up to 8%.

To explore the choice and effect of internal fixation in treating upper cervical vertebrae instability through anterior approach. From March 2000 to September 2010,83 patients with upper cervical vertebrae instability were treated with internal fixation through anterior approach. There were 59 males and 24 females with a mean age of 42 years old (ranged, 20 to 68). Among these patients, 36 patients were treated with odontoid screw fixation, 16 patients with C1,2 transarticular screw fixation, 23 patients with C2,3 steel plate fixation, 5 patients with odontoid screw and transarticular screw fixation,2 patients with odontoid screw and C2.3 steel plate fixation, 1 patient with C1,2 transarticular screw and C2,3 steel plate fixation. One patient with completely cervical vertebrae cord injury died of pulmonary infection after C1,2 transarticular screw fixation. Other patients were followed up from 8 to 36 months with an average of 15 months. Upper cervical vertebrae stability were restored without vertebral artery and spinal cord injury. Thirty-six patients were treated with odontoid screw fixation and 5 patients were treated with screw combined with transarticular screw fixation obtained bone union in the dentations without bone graft. Among the 16 patients treated with C1,2 transarticular screw fixation, 13 patients obtained bone union after bone graft; 1 patient died of pulmonary infection after surgery; 1 patient with comminuted odontoid fracture of type II C and atlantoaxial anterior dislocation did not obtain bone union after bone graft,but the fibrous healing was strong enough to maintain the atlantoaixal joint stability; 1 patient with obsolete atlantoaxial anterior dislocation were re-treated with Brooks stainless steel wire fixation and bone graft through posterior approach, and finally obtained bone union. It could obtain satisfactory effects depending on the difference of cervical vertebrae instability to choose the correctly surgical method.

The etiopathogenesis of orofacial pain remains complex and a number of pain referral patterns for this region have been reported in the literature. The purpose of this report is to describe the assessment and successful clinical management of orofacial pain possibly attributable to cervical origin. A 55-year-old male teacher with a 3-year history of pain in the right lower jaw, radiating to the ear, consulted our institute for assessment and management. The patient was unsuccessfully treated for dental pain and trigeminal neuralgia. The patient's functioning was grossly limited and the patient was unable to sleep because of severe pain. Current and previous medical and physical examinations revealed no infection, malignancies, or sinusitis. Palpation revealed no temporomandibular disorder, tenderness or myofascial trigger points. Examination of the cervical range of motion showed a reduction in rotation to the right side. The patient was treated for upper cervical joint dysfunction involving mobilization of the first three cervical vertebrae and motor control exercises. The patient had an almost complete resolution of symptoms and reported significant improvement in the Patient Specific Functional Scale (PSFS) and the Global Rating of Change (GRC) scale. This case study demonstrates the importance of considering, assessing and treating the cervical spine as a possible source of orofacial pain, and the positive role of cervical mobilization on these disorders.

Comparative observational study on the clinical presentation, intracranial volume measurements, and intracranial pressure scores in patients with either Chiari malformation Type I or idiopathic intracranial hypertension.

PubMed

Frič, Radek; Eide, Per Kristian

2017-04-01

OBJECTIVE Several lines of evidence suggest common pathophysiological mechanisms in Chiari malformation Type I (CMI) and idiopathic intracranial hypertension (IIH). It has been hypothesized that tonsillar ectopy, a typical finding in CMI, is the result of elevated intracranial pressure (ICP) combined with a developmentally small posterior cranial fossa (PCF). To explore this hypothesis, the authors specifically investigated whether ICP is comparable in CMI and IIH and whether intracranial volumes (ICVs) are different in patients with CMI and IIH, which could explain the tonsillar ectopy in CMI. The authors also examined whether the symptom profile is comparable in these 2 patient groups. METHODS The authors identified all CMI and IIH patients who had undergone overnight diagnostic ICP monitoring during the period from 2002 to 2014 and reviewed their clinical records and radiological examinations. Ventricular CSF volume (VV), PCF volume (PCFV), and total ICV were calculated from initial MRI studies by using volumetric software. The static and pulsatile ICP scores during overnight monitoring were analyzed. Furthermore, the authors included a reference (REF) group consisting of patients who had undergone ICP monitoring due to suspected idiopathic normal-pressure hydrocephalus or chronic daily headache and showed normal pressure values. RESULTS Sixty-six patients with CMI and 41 with IIH were identified, with comparable demographics noted in both groups. The occurrence of some symptoms (headache, nausea, and/or vomiting) was comparable between the cohorts. Dizziness and gait ataxia were significantly more common in patients with CMI, whereas visual symptoms, diplopia, and tinnitus were significantly more frequent in patients with IIH. The cranial volume measurements (VV, PCFV, and ICV) of the CMI and IIH patients were similar. Notably, 7.3% of the IIH patients had tonsillar descent qualifying for diagnosis of CMI (that is, > 5 mm). The extent of tonsillar ectopy was significantly different between the CMI and IIH cohorts (p < 0.001) but also between these 2 cohorts and the REF group. Pulsatile ICP was elevated in both cohorts without any significant between-group differences; however, static ICP was significantly higher (p < 0.001) in the IIH group. CONCLUSIONS This study showed comparable and elevated pulsatile ICP, indicative of impaired intracranial compliance, in both CMI and IIH cohorts, while static ICP was higher in the IIH cohort. The data did not support the hypothesis that reduced PCFV combined with increased ICP causes tonsillar ectopy in CMI. Even though impaired intracranial compliance seems to be a common pathophysiological mechanism behind both conditions, the mechanisms explaining the different clinical and radiological presentations of CMI and IIH remain undefined.

Analysis of the Determinants of Low Cervical Cancer Screening Uptake Among Nigerian Women.

Cervical cancer causes an estimated 266,000 deaths globally, 85% of which occurs in developing countries. It is a preventable disease, if detected and treated early via screen and treat , yet its burden is still huge in Nigeria. In 2012, 21.8% cases of cervical cancer and 20.3% deaths due to cervical cancer were recorded in Nigeria. This review, therefore, aims at indentifying the determinants of low cervical cancer screening in Nigeria in order to contribute in reducing the burden of the disease. Literature were obtained from Global Health, Popline and PubMed databases; WHO and other relevant websites using Eldis search engine; and from libraries in the University of Leeds and WHO in Geneva. Conceptual framework for analyzing the determinants of cervical cancer screening uptake among Nigerian women was formed by inserting service delivery component of the WHO health system framework into a modified Health Belief Model. Wrong perception of cervical cancer and cervical cancer screening due to low level of knowledge about the disease and inadequate cervical cancer prevention were identified as the major determinants of low cervical cancer screening uptake in Nigeria. Among women, belief in being at risk and/or severity of cervical cancer was low just as belief on benefits of cervical cancer screening, unlike high belief in barriers to screening. Support from the community and screening skills among health-workers were inadequate. Improving uptake of cervical cancer screening will reduce the burden of the disease. Therefore, researchers and other stakeholders interested in prevention of cervical cancer should carryout studies to identify interventions that could address the key determinants of low cervical cancer screening among Nigerian women.

Outpatient and Inpatient Single-Level Cervical Total Disc Replacement: A Comparison of 30-day Outcomes.

Retrospective cohort study. To compare 30-day postoperative outcomes between patients undergoing outpatient and inpatient single-level cervical total disc replacement surgery. Cervical total disc replacement (TDR) is a motion sparing treatment for cervical radiculopathy and myelopathy. It is an alternative to anterior cervical discectomy and fusion (ACDF) with a similar complication rate. Like ACDF, it may be performed in the inpatient or outpatient setting. Efforts to reduce healthcare costs are driving spine surgery to be performed in the outpatient setting. As cervical total disc replacement surgery continues to gain popularity, the safety of treating patients on an outpatient basis needs to be validated. The National Surgical Quality Improvement Program (NSQIP) database was queried for patients who underwent single-level cervical disc replacement surgery between 2006-2015. Complication data including 30-day complications, reoperation rate, readmission rate, and length of stay data was compared between the inpatient and outpatient cohort using univariate analysis. There were 531 (34.2%) patients treated as outpatients and 1,022 (65.8%) were treated on an inpatient basis. The two groups had similar baseline characteristics. The overall 30-day complication rate was 1.4% for inpatients and 0.6% for outpatients. Reoperation rate was 0.6% for inpatient and 0.4% for outpatients. Readmission rate was 0.9% and 0.8% for inpatient and outpatient, respectively. There were no statistical differences identified in rates of readmission, reoperation, or complication between the inpatient and outpatient cohorts. There was no difference between 30-day complications, readmission and reoperation rates between inpatients and outpatients who underwent a single-level cervical total disc replacement. Furthermore, the overall 30-day complication rates were low. This study supports that single-level cervical TDR can be performed safely in an outpatient setting. 3.

The purpose of the study was to evaluate the clinical and magnetic resonance imaging (MRI) outcome of cervical spine arthritis in children with juvenile idiopathic arthritis (JIA), who received anti-TNFα early in the course of cervical spine arthritis. Medical charts and imaging of JIA patients with cervical spine involvement were reviewed in this retrospective study. Data, including age at disease onset, JIA type, disease activity, treatment and clinical outcome were collected. Initial and followup MRI examinations of cervical spine were performed according to the hospital protocol to evaluate the presence of inflammation and potential chronic/late changes. Fifteen JIA patients with MRI proved cervical spine inflammation (11 girls, 4 boys, median age 6.3y) were included in the study: 9 had polyarthritis, 3 extended oligoarthritis, 2 persistent oligoarthritis and 1 juvenile psoriatic arthritis. All children were initially treated with high-dose steroids and methotrexate. In addition, 11 patients were treated with anti-TNFα drug within 3 months, and 3 patients within 7 months of cervical spine involvement confirmed by MRI. Mean observation time was 2.9y, mean duration of anti-TNFα treatment was 2.2y. Last MRI showed no active inflammation in 12/15 children, allowing to stop biological treatment in 3 patients, and in 3/15 significant reduction of inflammation. Mild chronic changes were found on MRI in 3 children. Early treatment with anti-TNFα drugs resulted in significantly reduced inflammation or complete remission of cervical spine arthritis proved by MRI, and prevented the development of serious chronic/late changes. Repeated MRI examinations are suggested in the follow-up of JIA patients with cervical spine arthritis.

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

Cervical cancer is the second most common cancer in females. Recent reports have revealed the critical role of cervical cancer stem cells (CSCs) in tumorigenicity and metastasis. Previously we demonstrated that A1E exerts an anti-proliferative action, which inhibits the growth of cervical cancer cells. A1E is composed of 11 oriental medicinal herbs. Cervical cancer cell culture, wund healing and invasion assay, flow cytometry, sheroid formation assay, and wstern blot assays were performed in HPV 16-positive SiHa cell and HPV 16-negative C33A cells. A1E targets the E6 and E7 oncogenes; thus, A1E significantly inhibited proliferation of human papilloma virus (HPV) 16-positive SiHa cells, it did not inhibit the proliferation of HPV-negative C33A cells. Accordingly, we investigated whether A1E can regulate epithelial-to-mesenchymal transition (EMT), CSC self-renewal, and stemness-related gene expression in cervical cancer cells. Down rgulation of cell migration, cell invasion, and EMT was observed in A1E-treated SiHa cells. Specifically, A1E-treated SiHa cells showed significant decreases in OCT-3/4 and Sox2 expression levels and in sphere formation. Moreover, CSCs makers ALDH+ and ALDH, CD133 double positive cell were significantly decreased in A1E-treated SiHa cells. However, A1E treatment did not down regulate ALDH+ expression and the number of ALDH/CD133 double positive cells in C33A cells. Taken together, A1E can inhibit CSCs and reduce the expression of stemness markers. Treating CSCs with A1E may be a potential therapy for cervical cancer.

Granulocyte-colony stimulating factor (G-CSF) producing malignant tumor has been reported to occur in various organs, and has been associated with poor clinical outcome. The aim of this study is to investigate the significance of tumor G-CSF expression in the chemosensitivity of uterine cervical cancer. The clinical data of recurrent or advanced cervical cancer patients who were treated with platinum-based chemotherapy were analyzed. Clinical samples, cervical cancer cell lines, and a mouse model of cervical cancer were employed to examine the mechanisms responsible for the development of chemoresistance in G-CSF-producing cervical cancer, focusing on myeloid-derived suppressor cells (MDSC). As a result, the tumor G-CSF expression was significantly associated with increased MDSC frequencies and compromised survival. In vitro and in vivo experiments demonstrated that the increased MDSC induced by tumor-derived G-CSF is involved in the development of chemoresistance. The depletion of MDSC via splenectomy or the administration of anti-Gr-1 antibody sensitized G-CSF-producing cervical cancer to cisplatin. In conclusion, tumor G-CSF expression is an indicator of an extremely poor prognosis in cervical cancer patients that are treated with chemotherapy. Combining MDSC-targeting treatments with current standard chemotherapies might have therapeutic efficacy as a treatment for G-CSF-producing cervical cancer.

Screen-and-treat cervical cancer prevention programs based on high-risk human papillomavirus (HPV) testing and cryotherapy have been shown to be effective in resource-limited settings. However, because cryotherapy is not 100% effective, follow-up is needed after treatment to detect post-treatment failures. We compared the test performances of high-risk HPV testing (Hybrid Capture 2) using self-collected and clinician-collected samples as well as cervical cytology for identifying cervical intraepithelial neoplasia grades 2 or 3 or invasive cervical cancer (CIN2+) among women who did (n=812) and did not (n=1858) undergo cryotherapy in a South African screen-and-treat trial. At 6 months after enrolment (and after cryotherapy, if performed), women were tested using all three screening methods and then underwent colposcopy/biopsy. A predefined subset of women (n=1,455) had extended follow-up with colposcopy/biopsy at 12 months. A total of 33 and 91 cases of CIN2+ were detected among treated and untreated women, respectively. The sensitivity of HPV testing using clinician-collected samples and cervical cytology did not differ by treatment status. HPV testing of clinician-collected samples detected the most cases of CIN2+ among both treated (85%) and untreated (91%) women (p=0.31). Cytology (at a cutoff of atypical squamous cells of undetermined significance or greater) detected 76% of cases among both treated and untreated women. However, the sensitivity of HPV testing using self-collected samples was significantly lower among treated versus untreated women (55% vs. 78%, p=0.01). HPV testing using self-collected vaginal specimens may be useful in primary screening but performs poorly for detecting post-treatment failures. Copyright © 2010 UICC.

Background: We performed a cross-sectional study in Indonesia to evaluate the performance of a single-visit approach of cervical cancer screening, using visual inspection with acetic acid (VIA), histology and cryotherapy in low-resource settings. Methods: Women having limited access to health-care facilities were screened by trained doctors using VIA. If the test was positive, biopsies were taken and when eligible, women were directly treated with cryotherapy. Follow-up was performed with VIA and cytology after 6 months. When cervical cancer was suspected or diagnosed, women were referred. The positivity rate, positive predictive value (PPV) and approximate specificity of the VIA test were calculated. The detection rate for cervical lesions was given. Results: Screening results were completed in 22 040 women, of whom 92.7% had never been screened. Visual inspection with acetic acid was positive in 4.4%. The PPV of VIA to detect CIN I or greater and CIN II or greater was 58.7% and 29.7%, respectively. The approximate specificity was 98.1%, and the detection rate for CIN I or greater was 2.6%. Conclusion: The single-visit approach cervical cancer screening performed well, showing See and Treat is a promising way to reduce cervical cancer in Indonesia. PMID:22850550

Patterns of care study of brachytherapy in New South Wales: cervical cancer treatment quality depends on caseload

Purpose We previously conducted modelling and a patterns of care study (POCS) that showed gynaecological brachytherapy (BT) was underutilized in New South Wales (NSW), the USA and Western Europe. The aim of the current study was to assess the quality of cervical BT in NSW, and to determine if caseload affects quality of treatment delivery. Material and methods All nine NSW radiation oncology departments that treated patients with cervical BT in 2003 were visited. Patient, tumour and treatment related data were collected. Quality of BT was assessed using published quality benchmarks. Higher and lower caseload departments were compared. Results The four higher cervical BT caseload departments treated 11-15 NSW residents in 2003, compared to 1-8 patients for the lower caseload departments. Cervix cancer patients treated at the higher caseload departments were more likely to be treated to a point A dose ≥ 80 Gy (58% vs. 14%, p = 0.001), and to have treatment completed within 8 weeks (66% vs. 35%, p = 0.02). Despite higher point A doses, there was no significant difference in proportions achieving lower than recommended rectal or bladder doses, implying better BT insertions in higher caseload departments. Conclusions Cervical BT in NSW was dispersed amongst a large number of departments and was frequently of sub-optimal quality. Higher quality BT was achieved in departments treating at least 10 patients per year. It is likely that improved outcomes will be achievable if at least 10 patients are treated per department per year. PMID:24790619

The authors put-forth this technical report to establish the feasibility of performing an anterior cervical corpectomy and fusion (ACCF) and a two-level anterior cervical discectomy and fusion (ACDF) using a minimally invasive approach with tubular retractors. First case: cervical spondylotic myelopathy secondary to a large postero-inferiorly migrated disc treated with corpectomy and reconstruction with a mesh cage and locking plate. Second case: cervical disc herniation with radiculopathy treated with a two-level ACDF. Both cases were operated with minimally invasive approach with tubular retractor using a single incision. Technical aspects and clinical outcomes have been reported. No intra or post-operative complications were encountered. Intra-operative blood loss was negligible. The patients had a cosmetic scar on healing. Standard procedure of placement of tubular retractors is sufficient for adequate surgical exposure with minimal invasiveness. Minimally invasive approach to anterior cervical spine with tubular retractors is feasible. This is the first report on use of minimally invasive approach for ACCF and two-level ACDF.

the aim of the study was to compare the clinical effect of Zero-profile interbody fusion device (Zero-P) with anterior cervical plate interbody fusion system (PCB) in treating cervical spondylosis. a total of 98 patients with cervical spondylosis (110 segments) in February 2011 to January 2013 were included in our hospital. All participants were randomly divided into observation group and control group with 49 cases in each group. The observation group was treated with Zero-P, while the control group received PCB treatment. Comparison of the two groups in neurological function score (JOA), pain visual analogue scale (VAS), the neck disability index (NDI), quality of life score (SF-36) and cervical curvature (Cobb angle) change were recorded and analyzed before and after treatment. The observation group was found with 90% excellent and good rate, which was higher than that of the control group (80%). Dysphagia rate in observational group was 16.33% (8/49), which was significantly less than that in control group (46.94%). Operation time and bleeding volume in the observation group was less than those in control group. Postoperative improvements of JOA score, VAS score, and NDI in observational group were also significantly better than that in control group (P<0.05). The clinical effect of Zero-P and PCB for the treatment of cervical spondylosis was quite fair, but Zero-P showed a better therapeutic effect with improvement of life quality.

The role of elective nodal irradiation (ENI) in radiotherapy for esthesioneuroblastoma (ENB) has not been clearly defined. We analyzed treatment outcomes of patients with ENB and the frequency of cervical nodal failure in the absence of ENI. Between August 1996 and December 2007, we consulted with 19 patients with ENB regarding radiotherapy. Initial treatment consisted of surgery alone in 2 patients; surgery and postoperative radiotherapy in 4; surgery and adjuvant chemotherapy in 1; surgery, postoperative radiotherapy, and chemotherapy in 3; and chemotherapy followed by radiotherapy or concurrent chemoradiotherapy in 5. Five patients did not receive planned radiotherapy because of disease progression. Including 2 patients who received salvage radiotherapy, 14 patients were treated with radiotherapy. Elective nodal irradiation was performed in 4 patients with high-risk factors, including 3 with cervical lymph node metastasis at presentation. Fourteen patients were analyzable, with a median follow-up of 27 months (range, 7-64 months). The overall 3-year survival rate was 73.4%. Local failure occurred in 3 patients (21.4%), regional cervical failure in 3 (21.4%), and distant failure in 2 (14.3%). No cervical nodal failure occurred in patients treated with combined systemic chemotherapy regardless of ENI. Three cervical failures occurred in the 4 patients treated with ENI or neck dissection (75%), none of whom received systemic chemotherapy. ENI during radiotherapy for ENB seems to play a limited role in preventing cervical nodal failure. Omitting ENI may be an option if patients are treated with a combination of radiotherapy and chemotherapy. Copyright © 2011 Elsevier Inc. All rights reserved.

Two cases of ruptured aneurysms in the posterior cervical regions associated with type-1 neurofibromatosis treated by transcatheter embolization are reported. Patients presented with acute onset of swelling and pain in the affected areas. Emergently performed contrast-enhanced CT demonstrated aneurysms and large hematomas widespread in the posterior cervical regions. Angiography revealed aneurysms and extravasations of the occipital artery. Patients were successfully treated by percutaneous transcatheter arterial microcoil embolization.

OBJECTIVE Adjacent-level disc degeneration following cervical fusion has been well reported. This condition poses a major treatment dilemma when it becomes symptomatic. The potential application of cervical arthroplasty to preserve motion in the affected segment is not well documented, with few studies in the literature. The authors present their initial experience of analyzing clinical and radiological results in such patients who were treated with arthroplasty for new or persistent arm and/or neck symptoms related to neural compression due to adjacent-segment disease after anterior cervical discectomy and fusion (ACDF). METHODS During a 5-year period, 11 patients who had undergone ACDF anterior cervical discectomy and fusion (ACDF) and subsequently developed recurrent neck or arm pain related to adjacent-level cervical disc disease were treated with cervical arthroplasty at the authors' institution. A total of 15 devices were implanted (range of treated levels per patient: 1-3). Clinical evaluation was performed both before and after surgery, using a visual analog scale (VAS) for pain and the Neck Disability Index (NDI). Radiological outcomes were analyzed using pre- and postoperative flexion/extension lateral radiographs measuring Cobb angle (overall C2-7 sagittal alignment), functional spinal unit (FSU) angle, and range of motion (ROM). RESULTS There were no major perioperative complications or device-related failures. Statistically significant results, obtained in all cases, were reflected by an improvement in VAS scores for neck/arm pain and NDI scores for neck pain. Radiologically, statistically significant increases in the overall lordosis (as measured by Cobb angle) and ROM at the treated disc level were observed. Three patients were lost to follow-up within the first year after arthroplasty. In the remaining 8 cases, the duration of follow-up ranged from 1 to 3 years. None of these 8 patients required surgery for the same vertebral level during the follow-up period. CONCLUSIONS Artificial cervical disc replacement in patients who have previously undergone cervical fusion surgery appears to be safe, with encouraging early clinical results based on this small case series, but more data from larger numbers of patients with long-term follow-up are needed. Arthroplasty may provide an additional tool for the management of post-fusion adjacent-level cervical disc disease in carefully selected patients.

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

Peroxisome proliferator-activated receptor gamma (PPAR γ) is activated by thiazolidinedione drugs (TZDs) and can promote anti-cancer properties. We used three TZDs (pioglitazone, rosiglitazone, and ciglitazone) to target cervical cancer cell lines and a nude mouse animal model. Each agent increased activation of PPAR γ, as judged by a luciferase reporter gene assay in three HPV-associated cell lines (CaSki, SiHa, and HeLa cells) while decreasing cellular proliferation in a dose-dependent manner. They also promoted Oil Red O accumulation in treated cell lines and upregulated the lipid differentiation marker adipsin. Interestingly, xenograft HeLa tumors in nude mice treated with 100 mg/kg/day pioglitazonemore » exhibited decreased growth compared to control mice or mice treated with standard cervical chemotherapy. In conclusion, TZDs slow tumor cell growth in vitro and in vivo with decreases in cell proliferation and increases in PPAR γ and adipsin. These agents may be interesting treatments or treatment adjuncts for HPV-associated cancers or perhaps even precancerous conditions. - Highlights: • Thiazolidinediones decreases cervical cancer proliferation. • Pioglitazone increases cervical cancer differentiation. • Pioglitazone decreases tumor growth in mice. • Pioglitazone may be a useful treatment adjunct.« less

The aim of this study was to describe whether the prophylactic use of a cervical pessary decreases the rate of premature birth in congenital diaphragmatic hernia (CDH) fetuses treated with fetoscopic tracheal occlusion (FETO). The study concerns a consecutive series of cases with CDH and FETO and a group of CDH without FETO. In a subgroup of the FETO group, a prophylactic cervical pessary was inserted the day following the procedure. Gestational age (GA) at birth was the primary outcome. Fifty-nine fetuses with FETO and 47 expectantly managed were included. The last 15 FETO had a cervical pessary inserted. The median GA at delivery in the FETO group with pessary was 35.1 weeks and was not different from that in the FETO group without a pessary (34.3 weeks; p = 0.28) but was below that in the expectantly managed group (38.3 weeks; p < 0.001). Early results suggest that prophylactic use of an Arabin cervical pessary does not prolong gestation of CDH fetuses treated with FETO. © 2015 John Wiley & Sons, Ltd. © 2015 John Wiley & Sons, Ltd.

Several approaches for treating severe uterine cervical stenosis after conization for cervical intraepithelial neoplasia have been reported; yet, the condition can still be difficult to treat successfully. We performed uterine cervical dilation surgery in two patients with severe stenosis, followed by insertion of the levonorgestrel-releasing intrauterine system, which is used for dysmenorrhea or endometriosis-related pain because of its strong progesterone activity. Patient 1 was a 34-year-old Japanese woman who was diagnosed with dysmenorrhea caused by recurrent uterine cervical stenosis and hematometra after laser conization. Patient 2 was a 44-year-old Japanese woman who developed dysmenorrhea and prolonged menstruation caused by uterine cervical stenosis without hematometra. After providing informed consent, they underwent cervical dilation surgery followed by insertion of the levonorgestrel-releasing intrauterine system. After treatment, their symptoms immediately improved, and after removal of their devices, they remained asymptomatic. To the best of our knowledge, this is the first report to confirm the usefulness and easy applicability of the levonorgestrel-releasing intrauterine system for uterine cervical stenosis. Although we had success with the method, this study of two patients is preliminary. Further study with larger numbers of patients is necessary to confirm the usefulness of our technique.

Study Design: Multicenter retrospective case series and review of the literature. Objective: To determine the rate of esophageal perforations following anterior cervical spine surgery. Methods: As part of an AOSpine series on rare complications, a retrospective cohort study was conducted among 21 high-volume surgical centers to identify esophageal perforations following anterior cervical spine surgery. Staff at each center abstracted data from patients’ charts and created case report forms for each event identified. Case report forms were then sent to the AOSpine North America Clinical Research Network Methodological Core for data processing and analysis. Results: The records of 9591 patients who underwent anterior cervical spine surgery were reviewed. Two (0.02%) were found to have esophageal perforations following anterior cervical spine surgery. Both cases were detected and treated in the acute postoperative period. One patient was successfully treated with primary repair and debridement. One patient underwent multiple debridement attempts and expired. Conclusions: Esophageal perforation following anterior cervical spine surgery is a relatively rare occurrence. Prompt recognition and treatment of these injuries is critical to minimizing morbidity and mortality. PMID:28451488

The dynamic cervical implant (DCI) is a novel motion-preserving concept for the treatment of degenerative cervical disorders. The aim of this prospective clinical study was to validate the concept and analyse clinical and radiological performance of the implant. One hundred seventy-five consecutive patients with degenerative cervical disorders, median age, 47 years, were treated with discectomy and DCI, and followed for 2 years. Clinical outcome was evaluated with the Neck Disability Index (NDI), the SF-12, and visual analogue scale (VAS) assessment of arm and neck pain. Range of motion (ROM) and cervical alignment were analysed using radiographic imaging. All clinical outcome measures--VAS neck and arm pain, NDI, and SF-12 mental and physical component summaries--improved significantly after surgery (each p < 0.001) and remained stable over the whole observation period. The ROM (flexion/extension) at the level treated with DCI was slightly reduced, but no significant changes could be verified at the adjacent levels. Six surgery or device-related adverse events were documented during the study. Good clinical and excellent radiological outcomes demonstrate that DCI is a safe and efficient treatment option in patients with degenerative cervical disorders.

Invasive squamous carcinoma of the cervix is preceded by a series of premalignant changes described as mild, moderate, or severe dysplasia, and carcinoma in situ. These premalignant states are identified by cervical cytology, diagnosed by colposcopy and if effectively treated, can prevent invasive squamous carcinoma of the cervix. Because of the apparent biological variation of the premalignant states, even the most aggressive cervical screening program cannot be expected to eliminate all invasive squamous cancer of the cervix. Optimal results of a cervical screening program will be achieved when all women under 35 years of age and sexually active have an annual cytological smear; the cytology is screened by a laboratory with high quality control; the patient's positive cytology is accurately assessed by an experienced colposcopist, and the premalignant lesion is effectively treated.

Arrhythmogenic cardiomyopathy (ACM) is characterized by redistribution of junctional proteins, arrhythmias, and progressive myocardial injury. We previously reported that SB216763 (SB2), annotated as a GSK3β inhibitor, reverses disease phenotypes in a zebrafish model of ACM. Here, we show that SB2 prevents myocyte injury and cardiac dysfunction in vivo in two murine models of ACM at baseline and in response to exercise. SB2-treated mice with desmosome mutations showed improvements in ventricular ectopy and myocardial fibrosis/inflammation as compared with vehicle-treated (Veh-treated) mice. GSK3β inhibition improved left ventricle function and survival in sedentary and exercised Dsg2mut/mut mice compared with Veh-treated Dsg2mut/mut mice and normalized intercalated disc (ID) protein distribution in both mutant mice. GSK3β showed diffuse cytoplasmic localization in control myocytes but ID redistribution in ACM mice. Identical GSK3β redistribution is present in ACM patient myocardium but not in normal hearts or other cardiomyopathies. SB2 reduced total GSK3β protein levels but not phosphorylated Ser 9–GSK3β in ACM mice. Constitutively active GSK3β worsens ACM in mutant mice, while GSK3β shRNA silencing in ACM cardiomyocytes prevents abnormal ID protein distribution. These results highlight a central role for GSKβ in the complex phenotype of ACM and provide further evidence that pharmacologic GSKβ inhibition improves cardiomyopathies due to desmosome mutations.

Paclitaxel, isolated from Taxus brevifolia , is considered to be an efficacious agent against a wide spectrum of human cancers, including human cervical cancer. However, dose-limiting toxicity and high cost limit its clinical application. Curcumin, a nontoxic food additive, has been reported to improve paclitaxel chemotherapy in mouse models of cervical cancer. However, the underlying mechanisms remain unclear. In this study, two human cervical cancer cell lines, CaSki [human papilloma virus (HPV)16-positive] and HeLa (HPV18-positive), were selected in which to investigate the effect of curcumin on the anticancer action of paclitaxel and further clarify the mechanisms. Flow cytometry and MTT analysis demonstrated that curcumin significantly promoted paclitaxel-induced apoptosis and cytotoxicity in the two cervical cell lines compared with that observed with paclitaxel alone (P<0.05). Reverse transcription-polymerase chain reaction indicated that the decline of HPV E6 and E7 gene expression induced by paclitaxel was also assisted by curcumin. The expression levels of p53 protein and cleaved caspase-3 were increased significantly in the curcumin plus paclitaxel-treated HeLa and CaSki cells compared with those in the cells treated with paclitaxel alone (P<0.01). Significant reductions in the levels of phosphorylation of IκBα and the p65-NF-κB subunit in CaSki cells treated with curcumin and paclitaxel were observed compared with those in cells treated with paclitaxel alone (P<0.05). This suggests that the combined effect of curcumin and paclitaxel was associated with the NF-κB-p53-caspase-3 pathway. In conclusion, curcumin has the ability to improve the paclitaxel-induced apoptosis of HPV-positive human cervical cancer cell lines via the NF-κB-p53-caspase-3 pathway. Curcumin in combination with paclitaxel may provide a superior therapeutic effect on human cervical cancer.

Studies of see-and-treat management of cervical intraepithelial neoplasia (CIN) vary in their inclusion criteria, resulting in a broad range of overtreatment rates. To determine overtreatment rates in see-and-treat management of women referred for colposcopy because of suspected CIN, in order to define circumstances supporting see-and-treat management. MEDLINE, EMBASE, and the Cochrane Library were searched from inception up to 12 May 2014. Studies of see-and-treat management in women with a reported cervical smear result, colposcopic impression, and histology result were included. Methodological quality was assessed with the Newcastle-Ottawa scale. We used the inverse variance method for pooling incidences, and a random-effects model was used to account for heterogeneity between studies. Overtreatment was defined as treatment in patients with no CIN or CIN1. Thirteen studies (n = 4611) were included. The overall overtreatment rate in women with a high-grade cervical smear and a high-grade colposcopic impression was 11.6% (95% CI 7.8-15.3%). The overtreatment rate in women with a high-grade cervical smear and low-grade colposcopic impression was 29.3% (95% CI 16.7-41.9%), and in the case of a low-grade smear and high-grade colposcopic impression it was 46.4% (95% CI 15.7-77.1%). In women with a low-grade smear and low-grade colposcopic impression, the overtreatment rate was 72.9% (95% CI 68.1-77.7%). The pooled overtreatment rate in women with a high-grade smear and high-grade colposcopic impression is at least comparable with the two-step procedure, which supports the use of see-and-treat management in this subgroup of women. See-and-treat management is justified in the case of a high-grade smear and a high-grade colposcopic impression. © 2015 Royal College of Obstetricians and Gynaecologists.

Modified anterior-only reduction and fixation for traumatic cervical facet dislocation (AO type C injuries).

Kanna, Rishi M; Shetty, Ajoy P; Rajasekaran, S

2018-06-01

Surgical reduction of uni and bi-facetal dislocations of the cervical spine (AO type C injuries) can be performed by posterior, anterior or combined approaches. Ease of access, low infection rates and less risks of neurological worsening has popularized anterior approach. However, the reduction of locked cervical facets can be intricate through anterior approach. We analyzed the safety, efficacy and outcomes at a minimum 1 year, of a novel anterior reduction technique for consecutively treated cervical facet dislocations. Patients with single level traumatic sub-axial cervical dislocation (n = 39) treated by this modified anterior technique were studied. The technique involved standard Smith-Robinson approach, discectomy beyond PLL, use of inter-laminar distracter to distract while Caspar pins were used as "joysticks" (either flexion-extension or lateral rotation moments are provided), to reduce the sub-luxed facets. Among 51 patients with cervical type C injury treated during the study period, 4 patients who had spontaneous reduction and 8 treated by planned global fusion were excluded. 39 patients of mean age 49.9 years were studied. The levels of injury included (C3-4 = 2, C4-5 = 5, C5-6 = 20, C6-7 = 12). 18 were bi-facetal and 21 were uni-facetal dislocation. One facet was fractured in 17 and both in 5 patients. 30% (n = 13) had a concomitant disc prolapse. The neurological status was as follows: 9 ASIA A, 9 ASIA C, 13 ASIA D and 8 ASIA E. All the patients were successfully reduced by this technique and fixed with anterior locking cervical locking plates. No supplemental posterior surgery was performed. 22 patients with incomplete deficit showed recovery. The mean follow-up was 14.3 months and there was no implant failure except one patient who had partial loss of the reduction. Patients with traumatic sub-axial cervical dislocation (AO type C injuries) can be safely and effectively reduced by this technique. Other advantages include minimal blood loss, less risks of infection, shorted fusion zone, good fusion rate and neurological recovery.

Limited data exist on pediatric subaxial cervical spine injuries. The goal of this study was to characterize the injuries and initial treatment of a large consecutive series of patients with injuries from C3 to C7. Medical records and radiographs of consecutive patients admitted with cervical spine fractures and/or dislocations at a single level 1 pediatric trauma center from 2003 to 2013 were reviewed. Data abstracted included age, injury type and level, mechanism of injury, associated nonspine injuries, neurological status, length of hospitalization, and initial treatment. Fifty-one patients were grouped into 3 age ranges: infant, 0 to 3 years (2); youth, 4 to 12 years (13); and adolescent, 13 to 16 years (36). Isolated fractures were identified in both infants and accounted for most of injuries in youths (85%) and adolescents (86%). Single vertebra or single vertebral level injuries were present in 65% of patients, most commonly at C7 (36%) or C6 (29%). No correlation existed between cervical level injured and patient age. Multiple cervical spine injuries occurred in 1 infant, 3 youths, and 14 adolescents. Other concomitant thoracic and/or lumbar spine injuries were found in 1 infant and 3 adolescents. The most common mechanisms of injury were motor vehicle accidents (53%) and sports (14%). High-energy trauma was associated with higher rates of noncontiguous spinal injuries and associated nonspinal injuries, with a longer length of hospitalization. Neurological deficits were observed in 8 patients: 1 infant, 2 youths, and 5 adolescents, of which 5 resulted from high-energy trauma. One infant and all youth patients were treated nonoperatively; 26 adolescents (73%) were treated in a cervical collar or with observation, 1 was treated with halo-vest immobilization, and 9 had surgical treatment. Most subaxial cervical spine injuries in pediatric and adolescent patients are isolated fractures at C6 and C7. High-energy mechanisms are associated with noncontiguous spinal injuries and other nonspine injuries. Most patients can be treated in a cervical collar, but adolescent patients are more likely to require halo placement or surgical intervention. Level IV-retrospective, diagnostic.

The purposes of this study were to determine the separate and interactive functions of progesterone and estradiol in regulating the cervical prostaglandin (PG) system in pregnant sheep at 0.7 gestations. At 106-108 days of gestational age (dGA), ewes were treated with vehicle for 14 days (n = 5) or vehicle for 12 days followed by estradiol 5 mg twice a day, intramuscularly for 2 days (n = 5) or progesterone 100 mg, twice a day, intramuscularly for 14 days (n = 5) or progesterone 100 mg twice a day, intramuscularly for 10 days and then 2 days vehicle followed by estradiol 5 mg twice a day intramuscularly for 2 days (n = 5). At 121-123 dGA, cervical tissues were obtained under halothane anesthesia. Cervical RNA and protein were extracted and analyzed for prostaglandin-endoperoxide synthase 2 (COX2), two PGE(2) receptors, PTGER2 and PTGER4, and estrogen receptor alpha (ESR1) by Northern and Western blot analysis. Immunocytochemistry and in situ hybridization were applied to localize cellular distribution of COX2, PTGER2, and PTGER4 in the cervix. Data were analyzed by ANOVA. COX2 and PTGER4 mRNAs and proteins were increased (P < 0.05) in ewes treated with combined estradiol and progesterone but not in ewes treated with estradiol or progesterone alone compared with controls. ESR1 mRNA was increased in ewes treated with progesterone and estradiol plus progesterone. In contrast, PTGER2 mRNA and protein remained the same after all treatments. COX2 mRNA and protein were localized only in cervical glandular epithelial cells, whereas PTGER2 and PTGER4 were localized in both cervical glandular epithelial and smooth muscle cells. In conclusion, these data suggest that additional progesterone priming at 0.7 gestations synergizes with estradiol to induce cervical COX2, PTGER4, and ESR1 and support our hypothesis that stimulation of the cervical PG system by estradiol is optimized by sufficient progesterone priming in the pregnant sheep cervix.

The role of contemporary radiotherapy (RT) has not yet been elucidated, mainly because of the low incidence of cervical esophageal cancer. The purpose of this study was to analyze the outcome in patients with cervical esophageal cancer treated with definitive RT. A total of 115 patients with cervical esophageal cancer treated with definitive RT during January 2001 through April 2012 in our center were analyzed. Eighty patients received RT alone and 35 patients received concurrent chemoradiotherapy with cisplatin administered either weekly (30 mg/m2) or every 3 weeks (80 mg/m2). The median follow-up time was 17.1 months. For all patients, the overall 2-year local failure-free survival (LFFS), regional failure-free survival (RFFS), distant failure-free survival (DFFS), and overall survival (OS) rate was 68.3%, 83.3%, 75.7%, and 47.6%, respectively. Definitive RT accomplished a satisfactory local control rate and contributed to organ preservation for patients with cervical esophageal cancer. 2015. © 2014 Wiley Periodicals, Inc.

High-risk human papillomaviruses (HPVs) infect epithelial cells and are causally associated with cervical cancer, but HPV infection is not sufficient for carcinogenesis. Previously, we reported that estrogen signaling in the stromal tumor microenvironment is associated with cervical cancer maintenance and progression. We have now determined how HPV oncogenes and estrogen treatment affect genome-wide host gene expression in laser-captured regions of the cervical epithelium and stroma of untreated or estrogen-treated nontransgenic and HPV-transgenic mice. HPV oncogene expression in the cervical epithelium elicited significant gene-expression changes in the proximal stromal compartment, and estrogen treatment uniquely affected gene expression in the cervical microenvironment of HPV-transgenic mice compared with nontransgenic mice. Several potential estrogen-induced paracrine-acting factors were identified in the expression profile of the cervical tumor microenvironment. The microenvironment of estrogen-treated HPV-transgenic mice was significantly enriched for chemokine/cytokine activity and inflammatory and immune functions associated with carcinogenesis. This inflammatory signature included several proangiogenic CXCR2 receptor ligands. A subset of the same CXCR2 ligands was likewise increased in cocultures of early-passage cells from human cervical samples, with levels highest in cocultures of cervical fibroblasts and cancer-derived epithelial cells. Our studies demonstrate that high-risk HPV oncogenes profoundly reprogram the tumor microenvironment independently of and synergistically with estrogen. These observations illuminate important means by which HPVs can cause cancer through alterations in the tumor microenvironment. PMID:29073104

The aim of this study was to systematically review the prognostic and predictive significance of cell biological markers in cervical cancer patients primarily treated with (chemo)radiation. A PubMed, Embase, and Cochrane literature search was performed. Studies describing a relation between a cell biological marker and survival in {>=}50 cervical cancer patients primarily treated with (chemo)radiation were selected. Study quality was assessed, and studies with a quality score of 4 or lower were excluded. Cell biological markers were clustered on biological function, and the prognostic and predictive significance of these markers was described. In total, 42 studies concerning 82 cell biologicalmore » markers were included in this systematic review. In addition to cyclooxygenase-2 (COX-2) and serum squamous cell carcinoma antigen (SCC-ag) levels, markers associated with poor prognosis were involved in epidermal growth factor receptor (EGFR) signaling (EGFR and C-erbB-2) and in angiogenesis and hypoxia (carbonic anhydrase 9 and hypoxia-inducible factor-1{alpha}). Epidermal growth factor receptor and C-erbB-2 were also associated with poor response to (chemo)radiation. In conclusion, EGFR signaling is associated with poor prognosis and response to therapy in cervical cancer patients primarily treated with (chemo)radiation, whereas markers involved in angiogenesis and hypoxia, COX-2, and serum SCC-ag levels are associated with a poor prognosis. Therefore, targeting these pathways in combination with chemoradiation may improve survival in advanced-stage cervical cancer patients.« less

Cervical pneumatocyst.

2011-09-01

The authors present the case of a 56-year-old right hand-dominant woman who was referred for chronic neck pain and a second opinion regarding a cervical lesion. The patient's pain was localized to the subaxial spine in the midline. She reported a subjective sense of intermittent left arm weakness manifesting as difficulty manipulating small objects with her hands and fingers. She also reported paresthesias and numbness in the left hand. Physical and neurological examinations demonstrated no abnormal findings except for a positive Tinel sign over the left median nerve at the wrist. Electromyography demonstrated bilateral carpal tunnel syndrome with no cervical radiculopathy. Cervical spine imaging demonstrated multilevel degenerative disc disease and a pneumatocyst of the C-5 vertebral body. The alignment of the cervical spine was normal. A review of the patient's cervical imaging studies obtained in 1995, 2007, 2008, and 2010 demonstrated that the pneumatocyst was not present in 1995 but was present in 2007. The lesion had not changed in appearance since 2007. At an outside institution, multilevel fusion of the cervical spine was recommended to treat the pneumatocyst prior to evaluation at the authors' institution. The authors, however, did not think that the pneumatocyst was the cause of the patient's neck pain, and cervical pneumatocysts typically have a benign course. As such, the authors recommended conservative management and repeated MR imaging in 6 months. Splinting was used to treat the patient's carpal tunnel syndrome.

Inhibiting CD146 by its Monoclonal Antibody AA98 Improves Radiosensitivity of Cervical Cancer Cells.

Cheng, Huawen

BACKGROUND Cervical cancer is one of the major causes of cancer death of females worldwide. Radiotherapy is considered effective for cervical cancer treatment, but the low radiosensitivity found in some cases severely affects therapeutic outcomes. This study aimed to reveal the role of CD146, an important adhesion molecule facilitating tumor angiogenesis, in regulating radiosensitivity of cervical cancer cells. MATERIAL AND METHODS CD146 protein expression was compared in normal cells, cervical cancer cells with lower radiosensitivity, and cervical cancer cells with higher sensitivity from cervical squamous cell carcinoma patients. Anti-CD146 monoclonal antibody AA98 was used to inhibit CD146 in human cervical cancer SiHa cells with relatively low radiosensitivity, and then the cell survival and apoptosis changes after radiation were detected by colony formation assay and flow cytometry. RESULTS CD146 protein was significantly up-regulated in cervical cancer cells (P<0.001), especially in cancer cells with lower radiosensitivity. The SiHa cells treated with AA98 showed more obvious inhibition in cell survival (P<0.05) and promotion in cell apoptosis (P<0.01) after radiation, compared to the untreated cells. More dramatic changes in apoptotic factors Caspase 3 and Bcl-XL were also detected in AA98-treated cells. CONCLUSIONS These results indicate that inhibiting CD146 improves the effect of radiation in suppressing SiHa cells. This study shows the potential of CD146 as a target for increasing radiosensitivity of cervical cancer cells, which might allow improvement in treatment outcome in cervical cancer. Further studies are necessary for understanding the detailed mechanism of CD146 in regulating radiosensitivity.

Estimating the costs of cervical cancer screening in high-burden Sub-Saharan African countries.

To estimate the capital investment and recurrent costs of national cervical cancer screening and precancer treatment programs in 23 high-incidence countries in Sub-Saharan Africa in order to provide estimates of the investment required to tackle the burden of cervical cancer in this region. These 23 countries account for 64% of the annual cervical cancer deaths in this region. Secondary data were used to estimate the financial costs of equipment purchases and economic costs of screening and treating eligible women over a 10-year period. Screening would be by visual inspection with acetic acid and treatment by cryotherapy or loop electrosurgical excision procedure. Approximately US $59 million would be required to purchase treatment equipment if cryotherapy were placed at every screening facility. Approximately 20 million women would be screened over 10 years. Cost per woman screened in a screen-and-treat program was either US $3.33 or US $7.31, and cost per woman treated was either US $38 or US $71 depending on the location of cryotherapy equipment. It would take less than US $10 per woman screened to significantly decrease the cervical cancer deaths that will occur in Sub-Saharan Africa over the next 10 years.

Cervical cancer is caused by human papillomavirus (HPV). The disease develops over many years through a series of precancerous lesions. Cervical cancer can be prevented by HPV-vaccination, screening and treatment of precancer before development of cervical cancer. The treatment of high-grade cervical dysplasia (CIN 2+ ) has traditionally been by cervical conization. Surgical procedures are associated with increased risk of undesirable side effects including bleeding, infection, scarring (stenosis), infertility and complications in later pregnancies. An inexpensive, non-invasive method of delivering therapeutics locally will be favorable to treat precancerous cervical lesions without damaging healthy tissue. The feasibility and safety of a sustained, continuous drug-releasing cervical polymeric implant for use in clinical trials was studied using a large animal model. The goat (Capra hircus), non-pregnant adult female Boer goats, was chosen due to similarities in cervical dimensions to the human. Estrus was induced with progesterone CIDR® vaginal implants for 14days followed by the administration of chorionic gonadotropins 48h prior to removal of the progesterone implants to relax the cervix to allow for the placement of the cervical implant. Cervical implants, containing 2% and 4% withaferin A (WFA), with 8 coats of blank polymer, provided sustained release for a long duration and were used for the animal study. The 'mushroom'-shaped cervical polymeric implant, originally designed for women required redesigning to be accommodated within the goat cervix. The cervical implants were well tolerated by the animals with no obvious evidence of discomfort, systemic or local inflammation or toxicity. In addition, we developed a new method to analyze tissue WFA levels by solvent extractions and LS/MS-MS. WFA was found to be localized to the target and adjacent tissues with 12-16ng WFA/g tissue, with essentially no detectable WFA in distant tissues. This study suggests that the goat is a good large animal model for the future development and evaluation of therapeutic efficacy of continuous local drug delivery by cervical polymeric implants to treat precancerous cervical lesions.

Cervical cancer is a major cause of cancer-associated mortality in women in developing countries. Thus, novel early markers are required. Ion channels have gained great interest as tumor markers, including cervical cancer. The calcium-activated potassium channel KCNMA1 (subunit α-1 from subfamily M) has been associated with different malignancies, including tumors such as breast and ovarian cancer that are influenced by hormones. The KCNMA1 channel blocker iberiotoxin decreases the proliferation of HeLa cervical cancer cells. Nevertheless, KCNMA1 channel expression during cervical carcinogenesis remains elusive. Therefore, KCNMA1 expression was studied in cervical cancer development. FVB transgenic mice expressing the E7-oncogene of high-risk human papilloma virus, and non-transgenic mice were treated with estradiol-releasing pellets during 3 or 6 months to induce cervical lesions. Twenty-four human cervical biopsies from non-cancerous, low- or high-grade intraepithelial lesions, or cervical cancer were also studied. mRNA and protein expression was assessed by reverse transcription-quantitative polymerase chain reaction and immunohistochemistry, respectively. Cervical dysplasia and carcinoma were observed only in the transgenic mice treated with estradiol for 3 and 6 months, respectively. Estradiol treatment increased KCNMA1 mRNA and protein expression in all groups; however, the highest levels were observed in the transgenic mice with carcinoma. KCNMA1 protein expression in the squamous cells of the transformation zone was observed only in the transgenic mice with cervical dysplasia or cancer. Human biopsies from non-cancerous cervix did not display KCNMA1 protein expression; in contrast, the majority of the tissues with cervical lesions (16/18) displayed KCNMA1 protein expression. The lowest channel immunostaining intensity was observed in biopsies from low-grade dysplasia and the strongest in the carcinoma tissues. These results suggest KCNMA1 channels as potential early cervical cancer markers. PMID:29725443

A retrospective study of a consecutive series of traumatic cervical spine injuries treated with halo vest immobilization (HVI) over an 8-year period at a level 1 trauma center. To assess survivorship, success, and causes of failure of HVI in the management of cervical spine injuries. The use of HVI has been increasingly questioned as an immobilization technique in cervical trauma due to reports of high complication rates and unacceptable treatment results. It was our hypothesis that selective use of updated HVI could demonstrate higher clinical success rates and lower complication rates compared to several previous landmark studies. All patients with traumatic cervical spine injuries treated with HVI between 1998 and 2006 at a single level 1 trauma center were reviewed retrospectively. With Internal Review Board approval, the trauma, spine, and orthotics databases were reviewed for (1) injury type, (2) patient age, (3) complications and comorbidities, (4) survivorship of the device and (5) treatment outcome. Four hundred ninety traumatic cervical spine injuries in 342 patients were treated with HVI. Thirty-one (9%) patients were lost to follow-up. Average age was 41 years (2-94). HVI was used as definitive treatment in 288 (84%) patients and in conjunction with surgical intervention in 54 (16%) patients. One hundred thirteen (35%) complications occurred, the most common of which were pin site infections (39) and instability (38). Two hundred seven (74%) of the 289 halo survivors with appropriate follow-up completed the initially prescribed time period of HVI. Two hundred eight of 247 (85%) halos placed as stand-alone management achieved their intended goal. Treatment with HVI was successful in 85% of patients and 74% of survivors completed their intended treatment period. Complications, though common, were mostly not severe. HVI is still a reasonable treatment option in managing cervical spine injuries.

Total disc replacement (TDR) is typically indicated in young patients with a cervical soft disc herniation. There are few data on the activity level of patients after cervical TDR, in particular from young patients who are expected to have a high activity level with frequent exercising. The expectation is that returning to active sports after cervical TDR is not restricted. Fifty patients were treated with a monosegmental cervical TDR at our department between May 2006 and March 2012. Clinical status and radiographic parameters were evaluated preoperatively and during follow-up. In addition, information was gathered regarding neck disability index, pain, a questionnaire concerning athletic aspects, and a modified Tegner activity score. The study design was a prospective case series. All patients were treated with the Prestige artificial cervical disc for a single-level soft disc herniation with radiculopathy. The average age was 40 years, and the mean follow-up period was 53 months (range, 26-96). The median neck disability index during follow-up was 5, and median visual analog scale for pain was 2. Two professional athletes, 20 semiprofessionals, 24 hobby athletes, and 5 patients with a very low activity level were treated. The median time to resumption of sporting activity was 4 weeks after surgery. All professionals and semiprofessionals recovered to their previous activity level. All of the 20 hobby athletes recovered to resume their sport participation. The modified Tegner preoperative score was 4 and the postoperative score was 3.5 (P = 0.806). We found that cervical TDR did not prohibit sporting activities. All patients recovered and were able to take part in their previous activities at an appropriate intensity level.

Osteoarthritis of the spine is a major global health problem, it is an epidemic of our times. It affects all parts of the spine, but the hardest to treat is its cervical region. The cervical spine is most mobile, delicate and sensitive to any load. It requires special care in conservative treatment. To date the selection of effective therapeutic approaches has been controversial. The aim of the study was to assess the progress of rehabilitation in patients with cervical radicular pain syndrome after using two different methods of treatment: HILT and spinal axial traction with the use of Saunders device. The randomized study included 150 patients (81 women and 69 men, aged 24-67 years, mean age 45.5) divided into two groups of 75 patients each with characteristic symptoms of radicular pain. The measurement of the range of cervical spine movement of the cervical spine, visual analog scale for pain - VAS and a NDI questionnaire (Neck Disability Index - Polish version) - an indicator of functional disorders - were used to evaluate the effectiveness of the two different therapies. The results obtained by Saunders method remained significantly higher than those obtained when HILT laser therapy was used for most of the examined parameters. A thorough analysis of the results showed greater analgesic efficacy, improved global mobility and reduced functional impairment in patients treated with Saunders method. Both therapeutic methods manifest analgesic effect and a positive impact on the improvement of range of cervical spine movement in patients with radicular pain in this spine region. HILT laser therapy and Saunders traction device reduce neck disability index in the treated patients. © 2015 MEDPRESS.

Treatment of cervical radiculopathy with disk arthroplasty has been approved by the U.S. Food and Drug Administration since 2007. Recently, a significant increase in clinical data including mid- and long-term follow-up has become available, demonstrating the superiority of disk arthroplasty compared with anterior discectomy and fusion. The aim of this project is to assess the nationwide use of cervical disk arthroplasty. The University Healthcare Consortium database was accessed for all elective cases of patients treated for cervical radiculopathy caused by disk herniation (International Classification of Diseases [ICD] 722.0) from the fourth quarter of 2012 to the third quarter of 2015. Within this 3-year window, temporal and socioeconomic trends in the use of cervical disk replacement for this diagnosis were assessed. Three thousand four hundred forty-six cases were identified. A minority of cases (10.7%) were treated with disk arthroplasty. Median hospital charges were comparable for cervical disk replacement ($15,606) and anterior cervical fusion ($15,080). However, utilization was seen to increase by nearly 70% during the timeframe assessed. Disk arthroplasty was performed in 8% of patients in 2012 to 2013, compared with 13% of cases in 2015. Disk replacement use was more common for self-paying patients, patients with private insurance, and patients with military-based insurance. There was widespread variation in the use of cervical disk replacement between regions, with a nadir in northeastern states (8%) and a peak in western states (20%). Over a short, 3 -year period there has been an increase in the treatment of symptomatic cervical radiculopathy with disk arthroplasty. The authors predict a further increase in cervical disk arthroplasty in upcoming years. Copyright © 2016 Elsevier Inc. All rights reserved.

HIV-infected women are at an increased risk of cervical cancer, especially in resource-limited countries. Cervical cancer prevention strategies focus treating cervical high-grade squamous intraepithelial lesions (HSIL). The management of low-grade squamous intraepithelial lesions (LSIL) in HIV-infected women is unknown. HIV treatment clinic in Johannesburg, South Africa. We randomized HIV-infected women with histologic cervical LSIL to cervical cryotherapy vs. no treatment (standard of care). Cervical high-risk human papillomavirus testing (hrHPV) was performed at baseline. All women underwent cervical cytology and colposcopic biopsies 12 months after enrollment. The primary end point was HSIL on histology at month 12. Chi-square was used to compare arms. Overall, 220 HIV-infected women were randomized to cryotherapy (n = 112) or no treatment (n = 108). Median age was 38 years, 94% were receiving antiretroviral therapy; median CD4 was 499 cells per cubic millimeter, and 59% were hrHPV positive. Cryotherapy reduced progression to HSIL: 2/99 (2%) in the cryotherapy arm and 15/103 (15%) in the no treatment arm developed HSIL, 86% reduction (95% confidence interval: 41% to 97%; P = 0.002). Among 17 HSIL end points, 16 were hrHPV+ at baseline. When restricting the analysis to hrHPV+ women, HSIL occurred in 2/61 (3%) in the cryotherapy arm vs. 14/54 (26%) in the no treatment arm, 87% reduction (95% confidence interval: 47% to 97%; P = 0.0004). Participants in the cryotherapy arm experienced greater regression to normal histology and improved cytologic outcomes. Treatment of cervical LSIL with cryotherapy decreased progression to HSIL among HIV-infected women especially if hrHPV positive. These results support treatment of LSIL in human papillomavirus test-and-treat approaches for cervical cancer prevention in resource-constrained settings.

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 (p<0.05) in both groups. Also there was a statistical difference between the groups regarding pain, pressure pain threshold, cervical flexion-extension (p<0.05); except cervical rotation, cervical lateral flexion and disability (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.

Abstract Treatment of cervical fracture and dislocation by improving the anterior cervical technique. Anterior cervical approach has been extensively used in treating cervical spine fractures and dislocations. However, when this approach is used in the treatment of locked facet joints, an unsatisfactory intraoperative reduction and prying reduction increases the risk of secondary spinal cord injury. Thus, herein, the cervical anterior approach was improved. With distractor and screw elevation therapy during surgery, the restoration rate is increased, and secondary injury to the spinal cord is avoided. To discuss the feasibility of the surgical method of treating traumatic cervical spine fractures and dislocations and the clinical application. This retrospective study included the duration of patients’ hospitalization from January 2005 to June 2015. The potential risks of surgery (including death and other surgical complications) were explained clearly, and written consents were obtained from all patients before surgery. The study was conducted on 86 patients (54 males and 32 females, average age of 40.1 ± 5.6 years) with traumatic cervical spine fractures and dislocations, who underwent one-stage anterior approach treatment. The effective methods were evaluated by postoperative follow-up. The healing of the surgical incision was monitored in 86 patients. The follow-up duration was 18 to 36 (average 26.4 ± 7.1) months. The patients achieved bones grafted fusion and restored spine stability in 3 to 9 (average 6) months after the surgery. Statistically, significant improvement was observed by Frankel score, visual analog scale score, Japanese Orthopedic Association score, and correction rate of the cervical spine dislocation pre- and postoperative (P < .01). The modified anterior cervical approach is simple with a low risk but a good effect in reduction. In addition, it can reduce the risk of iatrogenic secondary spinal cord injury and maintain optimal cervical spine stability as observed during follow-ups. Therefore, it is suitable for clinical promotion and application. PMID:28658125

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

Cervical tooth erosion is increasingly observed among adults and frequently associated with dentin sensitivity (DS). This study evaluated the effectiveness on DS of a biomimetic mineralization system (BIMIN) in comparison to the current standard treatment (Gluma(®) Desensitizer, Gluma). In this single-blind, 2-arm study, 40 patients with confirmed cervical DS were randomized to either the test group or the positive control group. A Visual-Analog-Scale (VAS) was used to assess DS following stimulation of the exposed dentin with a 2-s air blast. Assessments were made at baseline (pre-treatment), 2 days, 4, 8 and 12 weeks, and 12 months after treatment. Two-stage replicas were obtained from the treated teeth and gold sputtered at baseline, and 2 days, 3 and 12 months after treatment. Surface topography of the treated cervical lesions and occlusion of dentinal tubules were investigated using scanning electron microscopy (SEM). Both treatments led to a statistically significant reduction (P<0.0001) in DS that persisted over the entire 12-month observation period. Differences in DS between the treatments were not statistically significant. SEM photomicrographs demonstrated that a mineral layer concealed the dentinal tubules in the test group. In contrast, numerous dentinal tubules remained visible in cervical defects that were treated with Gluma. A biomimetic mineralization kit was successfully used to treat patients exhibiting DS. The effect was similar to using Gluma, and was likely the result of the deposition of an enamel-like layer on the exposed cervical dentin. Copyright © 2012 Academy of Dental Materials.

Treatment of recurrent and metastatic cervical cancer remains a challenge, especially in developing countries, which lack efficient screening programs. In recent years, artemisinin and its derivatives, such as dihydroartemisinin (DHA), which were traditionally used as anti-malarial agent, have been shown to inhibit tumor growth with low toxicity to normal cells. In this study, we investigated mechanisms underlying the anti-tumor effect of DHA in cervical cancer. We evaluated the role of DHA on the expression of bcl-2 and Raf kinase inhibitor protein (RKIP), which is a suppressor of metastasis. The MTT assay was used to compare the proliferation of untreated and DHA-treated Hela and Caski cervical cancer cells. Flow cytometry was used to determine the percentage of cells at each stage of the cell cycle in untreated and DHA-treated cells. We used RT-PCR and western blots to determine the expression of bcl-2 and RKIP mRNA and proteins. We evaluated the effect of DHA treatment in nude mice bearing Hela or Caski tumors. DHA-treated cells showed a time- and dose-dependent inhibition of proliferation and a significant increase in apoptosis. The expression of RKIP was significantly upregulated and the expression of bcl-2 was significantly downregulated in DHA-treated cells compared with control cells. DHA treatment caused (1) a significant inhibition of tumor growth and (2) a significant increase in the apoptotic index in nude mice bearing Hela or Caski tumors. Our data suggest that DHA inhibits cervical cancer growth via upregulation of RKIP and downregulation of bcl-2. PMID:24335512

We report a case of 29-year-old man diagnosed as a primary eosinophilic granuloma (EG) lesion of the seventh cervical vertebra. He had paresthesia on both arms, and grasping weakness for 10 days. Cervical magnetic resonance image (MRI) showed an enhancing mass with ventral epidural bulging and cord compression on the seventh cervical vertebra. Additionally, we performed spine series MRI, bone scan and positive emission tomography for confirmation of other bone lesions. These studies showed no other pathological lesions. He underwent anterior cervical corpectomy of the seventh cervical vertebra and plate fixation with iliac bone graft. After surgical management, neurological symptoms were much improved. Histopathologic evaluation confirmed the diagnosis of EG. There was no evidence of tumor recurrence at 12 months postoperative cervical MRI follow-up. We reported symptomatic primary EG of cervical spine successfully treated with surgical resection. PMID:24044083

A subset of the mucosotropic human papillomaviruses (HPV), including HPV16, are etiologic agents for the vast majority of cervical cancers, other anogenital cancers, and a subset of head and neck squamous cell carcinomas. HPV16 encodes three oncogenes: E5, E6, and E7. Although E6 and E7 have been well-studied and clearly shown to be important contributors to these cancers, less is known about E5. In this study, we used E5 transgenic mice to investigate the role of E5 in cervical cancer. When treated for 6 months with estrogen, a cofactor for cervical carcinogenesis, E5 transgenic mice developed more severe neoplastic cervical disease than similarly treated nontransgenic mice, although no frank cancers were detected. In addition, E5 when combined with either E6 or E7 induced more severe neoplastic disease than seen in mice expressing only one viral oncogene. Prolonged treatment of E5 transgenic mice with exogenous estrogen uncovered an ability of E5 to cause frank cancer. These data indicate that E5 acts as an oncogene in the reproductive tracts of female mice.

Retrospective case series. To discuss the clinical efficacy of anterior cervical surgery of decompression, reduction, stabilization, and fusion in treating subaxial cervical facet dislocation without spinal cord injury or with mild spinal cord injury monitored by spinal cord evoked potential. The optimal treatment of lower cervical facet dislocation has been controversial. Because of the risk of iatrogenic damage of neurological function, it is challenging for surgeons to manage the lower cervical facet dislocation without or with mild spinal cord injury. To avoid the risks, more secure strategy need to be designed. A retrospective study was performed on 17 cases of subaxial cervical facet dislocation without spinal cord injury or with mild spinal cord injury treated by anterior cervical surgery under spinal cord evoked potential monitor from January 2008 to June 2012. There were 12 males, 5 females, with a mean age of 40.1 years (from 21 to 73 yr). Dislocation sites: 1 in C3-C4, 2 in C4-C5, 6 in C5-C6, 8 in C6-C7; 10 cases with unilateral cervical facet dislocation, 7 cases with bilateral dislocation. Thirteen patients were preoperatively classified as grade D and 4 as E according to Frankel standard. All patients were followed up for average of 16 months. All operations were completed successfully. Postoperative radiographs showed that the sequence and curvature of the cervical spine were well recovered. And, evidence of intervertebral fusion was observed at 3 months in all cases. No redislocation or symptoms of spinal cord injury occurred. Thirteen cases with mild spinal cord injury recovered at 1 month after operation. Anterior cervical surgery of decompression, reduction, stabilization, and fusion monitored by spinal cord evoked potential is an effective and safe method for treatment of subaxial cervical facet dislocation without or with mild spinal cord injury. 4.

To describe the outcome of patients with twin-to-twin transfusion syndrome and cervical length ≤ 25 mm, treated with laser and an Arabin cervical pessary. Retrospective analysis of a consecutive series of all cases with severe twin-to-twin transfusion syndrome who underwent laser surgery: a group with cervical length above 25 mm (group A) and two groups who had a cervical length of 25 mm or less prior to the procedure. The first 8 cases (group B) were managed expectantly and the next 8 cases had a cervical pessary inserted immediately after laser surgery (group C). Gestational age at birth was the primary outcome. The secondary outcome was a composite one encompassing severe neonatal morbidity. The median gestational age at laser surgery was 20 weeks in all groups but the median gestational age at delivery was significantly higher in group C versus B (28 vs 32 weeks, p = 0.01). Severe neonatal morbidity was present in 18% in group C and 70% in group B (p < 0.01). Early results suggest a potential role for pessary use in prolonging gestation in cases with shortened cervix at the time of laser. A randomized trial to test this hypothesis should be performed. © 2012 John Wiley & Sons, Ltd.

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

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

2014-08-01

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

The aim of the present study was to investigate the potential effects of the 5,10,15,20-tetrakis (1-methylpyridinium-4-yl) porphyrin (TMPyP4) on the proliferation and apoptosis of human cervical cancer cells and the underlying mechanisms by which TMPyP4 exerted its actions. After human cervical cancer cells were treated with different doses of TMPyP4, cell viability was determined by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) method, the apoptosis was observed by flow cytometry (FCM), and the expression of p38 mitogen-activated protein kinase (MAPK), phosphated p38 MAPK (p-p38 MAPK), capase-3, MAPKAPK2 (MK-2) and poly ADP-ribose polymerase (PARP) was measured by Western blot analysis. The analysis revealed that TMPyP4 potently suppressed cell viability and induced the apoptosis of human cervical cancer cells in a dose-dependent manner. In addition, the up-regulation of p-p38 MAPK expression levels was detected in TMPyP4-treated human cervical cancer cells. However, followed by the block of p38 MAPK signaling pathway using the inhibitor SB203580, the effects of TMPyP4 on proliferation and apoptosis of human cervical cancer cells were significantly changed. It was indicated that TMPyP4-inhibited proliferation and -induced apoptosis in human cervical cancer cells was accompanied by activating the p38 MAPK signaling pathway. Taken together, our study demonstrates that TMPyP4 may represent a potential therapeutic method for the treatment of cervical carcinoma.

A 32 year Libyan male presented with the complaints of headache and diplopia. He was diagnosed with a cavernous sinus meningioma on the basis of MRI findings but no initial biopsy was taken. Depending on the radiologic diagnosis the patient was treated with gamma knife surgery twice, abroad. During follow up he developed left ear deafness and left cervical lymph adenopathy. An ENT evaluation with biopsy from the nasopharynx and cervical lymph node was taken. The histopathologic diagnosis of the resected tumour showed a nasopharyngeal carcinoma with cervical lymph node metastasis (poorly differentiated lympho-epithelial carcinoma). The cavernous sinus tumour which was initially treated as a meningioma was in fact metastasis from the nasopharyngeal carcinoma, making this an interesting and rare occurrence.

Chronic fatigue after treatment is a common adverse event in cancer patients, but there are few studies in long-term survivors of cervical cancer. The aim of this investigation was to explore the prevalence of chronic fatigue and its association with various clinical and treatment-related factors in a population-based cohort of Norwegian cervical cancer survivors treated by any modality. All patients, treated for cervical cancer from 2000 through 2007 in the Health Region of South-Eastern Norway, cancer-free, alive and aged ≤75years by the end 2013 (n=822) received a questionnaire covering chronic fatigue and other clinical variables. 461 of 822 survivors (56%) completed the questionnaire and 382 entered the analyses. Chronic fatigue was reported by 23% (95% confidence interval 19%-27%) with a median age of 52years (range 32-75) at survey, 11years (range 7-15) after diagnosis. Among survivors treated by minimal invasive- or radical surgery, 19% had chronic fatigue, while the prevalence was 28% in those treated with radiation and concomitant chemotherapy (chemoradiation). The chronic fatigue group reported significantly more cardiovascular disease, obesity, less physical activity, more treatment-related symptom experience, more menopausal symptoms, higher levels of anxiety and depressive symptoms, and poorer quality of life than the non-fatigued group. In multivariate analysis only increased level of depression and poorer global quality of life were significantly associated with chronic fatigue. Chronic fatigue was reported by 23% of long-term survivors after cervical cancer at a mean of 11years after treatment. Some of the associated factors are amenable to prevention and/or treatment and should be subjects of attention at follow-up. Copyright © 2017 Elsevier Inc. All rights reserved.

We assessed mortality, treatment response, and relapse among HIV-infected and HIV-uninfected women with cervical cancer in Rio de Janeiro, Brazil. Cohort study of 87 HIV-infected and 336 HIV-uninfected women with cervical cancer. Patients at the Brazilian National Institute of Cancer (2001-2013) were matched on age, calendar year of diagnosis, clinical stage, and tumor histology. Staging and treatment with surgery, radiotherapy, and/or chemotherapy followed international guidelines. We used a Markov model to assess responses to initial therapy, and Cox models for mortality and relapse after complete response (CR). Among 234 deaths, most were from cancer (82% in HIV-infected vs. 93% in HIV-uninfected women); only 9% of HIV-infected women died from AIDS. HIV was not associated with mortality during initial follow-up but was associated more than 1-2 years after diagnosis [overall mortality: stage-adjusted hazard ratio 2.02, 95% confidence interval (CI) 1.27-3.22; cancer-specific mortality: 4.35, 1.86-10.2]. Among 222 patients treated with radiotherapy, HIV-infected had similar response rates to initial cancer therapy as HIV-uninfected women (hazard ratio 0.98, 95% CI 0.58-1.66). However, among women who were treated and had a CR, HIV was associated with elevated risk of subsequent relapse (hazard ratio 3.60, 95% CI 1.86-6.98, adjusted for clinical stage). Among women with cervical cancer, HIV infection was not associated with initial treatment response or early mortality, but relapse after attaining a CR and late mortality were increased in those with HIV. These results point to a role for an intact immune system in control of residual tumor burden among treated cervical cancer patients.

The study was undertaken to assess the utility of cervico-vaginal/vault cytology in the follow-up of women treated for cervical cancer and benign gynecological conditions. Records of 3,523 cervico-vaginal smears from 2,658 women who underwent hysterectomy and/or radiotherapy or chemotherapy, over a 10-year period were retrieved. Data was collected on type of treatment received, indication for hysterectomy, age of patient, presenting symptoms, stage of tumor, interval since treatment, cytology and biopsy results. The results of cytology versus other parameters were analyzed separately for women treated for cervical cancer and those hysterectomized for benign indications. Malignant cells were detected in 141/1949 (7.2%) follow-up smears from treated cervical cancer cases (140 recurrences and 1 VAIN). Around 92% of recurrences of cervical cancer were detected with in 2 years of follow-up and 75% of these women were symptomatic. Cytology first alerted the clinicians to a recurrence in a quarter of cases. On the other hand, VAIN was detected in 5/1079 (0.46%) vault smears from 997 women hysterectomized for benign gynecologic disease. All these women were asymptomatic and majority (80%) were detected in follow-up smears performed between 3 and 10 years. Vault cytology is an accurate tool to detect local recurrences/VAIN in women treated for cervical cancer or benign gynecological conditions. It may even first alert the clinicians to a possibility of recurrence. However, due to extremely low prevalence of VAIN/vaginal cancer, it seems unwarranted in women hysterectomized for benign indications, especially in resource constrained settings.

Our previous study of whiplash injury found that abnormalities in the cervical muscles cause autonomic dystonia. Further research has found that abnormalities in the cervical muscles cause headache, chronic fatigue syndrome, vertigo, and dizziness. We named this group of diseases cervical neuro-muscular syndrome. Patients treated within a 2-year period from April 1, 2002 to March 31, 2004 reported good outcomes in 83.8% for headache, 88.4% for vertigo and dizziness, 84.5% for chronic fatigue syndrome, 88.0% for autonomic dystonia, and 83.7% for whiplash-associated disorder. A large number of outpatients present with general malaise, including many general physical complaints without identifiable cause. We propose that treatment of the cervical muscle is effective for general malaise.

The purpose of this study was to compare the outcomes of overall improvement, pain reduction, and treatment costs in matched patients with symptomatic, magnetic resonance imaging-confirmed cervical disk herniations treated with either spinal manipulative therapy (SMT) or imaging-guided cervical nerve root injection blocks (CNRI). This prospective cohort comparative-effectiveness study included 104 patients with magnetic resonance imaging-confirmed symptomatic cervical disk herniation. Fifty-two patients treated with CNRI were age and sex matched with 52 patients treated with SMT. Baseline numerical rating scale (NRS) pain data were collected. Three months after treatment, NRS pain levels were recorded and overall "improvement" was assessed using the Patient Global Impression of Change scale. Only responses "much better" or "better" were considered "improved." The proportion of patients "improved" was calculated for each treatment method and compared using the χ(2) test. The NRS and NRS change scores for the 2 groups were compared at baseline and 3 months using the unpaired t test. Acute and subacute/chronic patients in the 2 groups were compared for "improvement" using the χ(2) test. "Improvement" was reported in 86.5% of SMT patients and 49.0% of CNRI patients (P = .0001). Significantly more CNRI patients were in the subacute/chronic category (77%) compared with SMT patients (46%). A significant difference between the proportion of subacute/chronic CNRI patients (37.5%) and SMT patients (78.3%) reporting "improvement" was noted (P = .002). Subacute/chronic patients treated with SMT were significantly more likely to report relevant "improvement" compared with CNRI patients. There was no difference in outcomes when comparing acute patients only. Copyright © 2016 National University of Health Sciences. Published by Elsevier Inc. All rights reserved.

C2 radiculopathy is known to cause occipito-cervical pain, but their pathology is unclear because of its rarity and unique anatomy. In this paper, we investigated the mechanism of C2 radiculopathy that underwent microscopic cervical foraminotomies (MCF). Three cases with C2 radiculopathy treated by MCF were investigated retrospectively. The mean follow-up period was 24 months. Pre-operative symptoms, imaging studies including para-sagittal CT and MRI, rotational dynamic CT, and intraoperative findings were investigated. There were 1 male and 2 females. The age of patients were ranged from 50 to 79 years. All cases had intractable occipito-cervical pain elicited by the cervical rotation. C2 nerve root block was temporally effective. There was unilateral spondylosis in symptomatic side without obvious atlatoaxial instability. Para-sagittal MRI and CT showed severe foraminal stenosis at C1-C2 due to the bony spur derived from the lateral atlanto-axial joints. In one case, dynamic rotational CT showed that the symptomatic foramen became narrower on rotational position. MCF was performed in all cases, and the C2 nerve root was impinged between the inferior edge of the C1 posterior arch and bony spur from the C1-C2 joint. After surgery, occipito-cervical pain disappeared. This study demonstrated that mechanical impingement of the C2 nerve root is one of the causes of occipito-cervical pain and it was successfully treated by microscopic resection of the inferior edge of the C1 posterior arch. Para-sagittal CT and MRI, rotational dynamic CT, and nerve root block were effective for diagnosis.

After tuberculous pleurisy, lymphadenitis arising from cervical lesion is the second most common form of extrapulmonary tuberculosis. It is generally treated with antituberculosis agents, but some patients resist chemotherapy. In such cases, surgical resection is often considered as an alternative treatment. This study aims to evaluate the therapeutic outcome of cervical tuberculous lymphadenitis and the future course of treatment of this disease. We retrospectively reviewed the clinical charts of patients diagnosed at the Tokyo Metropolitan Tama Medical Center between 2009 and 2015 and identified 38 cases of cervical tuberculous lymphadenitis. Precisely 798 patients were registered for primary tuberculosis at our institution during the same period. Patient ages ranged from 21 to 85 years (average: 58.9 years), and the male-to-female ratio was 1:1.2. The range of tuberculosis progression was as follows: 30 (78.9%) in only the cervical lymph node, 3 in the other (axillary, mediastinal, and abdominal) lymph nodes, 1 in the lung and vertebrae lumbales, 2 in the lung, and 1 in the pleural membrane. All 38 patients were initially treated with antituberculous drugs at the Department of Pulmonary Medicine based on guidelines for tuberculosis cases in Japan. In seven cases, the antituberculous drugs were replaced due to side effects. Four cases involved a single drug-resistant strain, and one case involved a double drug-resistant strain. Thirty-three (86.8%) cases were cured by chemotherapy alone. The three patients resistant to chemotherapy were successfully treated through neck dissection. Thirty-six cases (94.7%) were cured by chemotherapy or chemotherapy and surgery. Local therapy could prove effective in cervical tuberculous lymphadenitis patients who exhibit an inadequate response to drugs. The role of neck dissection in cervical tuberculous lymphadenitis remains an important consideration. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Cervical neck pain is often caused by cervical disk pathology and may cause severe symptoms and disability. Surgeons and patients are increasingly aware of postsurgery-related complications. This stimulated the clinical usage of minimally invasive treatments such as percutaneous nucleoplasty (PCN) and pulsed radio frequency (PRF). However, scientific evidence on both treatments is limited. Our objective was to evaluate the efficacy of PCN compared to PRF in patients with contained cervical disk herniation. A prospective randomized clinical trial was conducted including 34 patients with radicular pain due to a single contained cervical disk herniation who were treated with either PCN or PRF. Demographic data were collected, and the Medical Outcomes Study 12-Item Short Form (SF-12) Health Survey, visual analog scale (VAS), and the Neck Disability Index (NDI) were completed 1, 2, and 3 months after treatment. Treatment satisfaction and complications were recorded. In the PCN group (n = 17, mean age 52.4 years, 10 female/7 male), patients were treated at C5 to C6 (8 cases) or C6 to C7 (9 cases). In the PRF group (n = 17, mean age 49.5 years, 8 female/9 male), patients were treated at C3 to C4 (1 case), C5 to C6 (10 cases), or C6 to C7 (6 cases). At 3 months, mean pain VAS improved significantly from baseline in the PCN group (mean improvement: 43.4 points) and in the PRF group (34.0 points). However, improvement in 1 group was not superior compared to the other group (P = 0.48). No serious complications were reported. Within 3 months, both PCN and PRF show significant pain improvement in patients with contained cervical disk herniation, but none is superior to the other. Both treatment options appear to be effective and safe in regular clinical practice. © 2016 World Institute of Pain.

Self-sampling to test for high risk human papilloma virus (HPV) is becoming an increasingly important component of cervical cancer screening. The aim of this observational study is to examine how women treated for high-grade cervical intraepithelial neoplasia (CIN) view HPV self-sampling. Invited to participate in the present study were patients who had undergone treatment of high-grade CIN (grade 2 or higher) and were followed-up at 6-months at the Karolinska University Hospital, Stockholm. The participants were instructed as to how to perform HPV self-sampling. Thereafter, the participants completed a questionnaire about HPV self-sampling and other cervical cancer screening methods, as well as about self-perceived risk of cervical cancer without regular gynecologic follow-up and about specific knowledge regarding HPV, CIN and cervical cancer. Altogether 479 women enrolled in this study. The participation rate was 96.6%. Nearly 75% of the participants stated they would consider performing the HPV self-sampling prior to their next gynecologic follow-up. Confidence in HPV self-sampling was a significant independent predictor of willingness to perform HPV self-sampling. However, confidence in HPV self-sampling was significantly lower than confidence in Papanicolaou smears and in HPV testing with samples collected by health professionals. Higher specific knowledge about HPV, CIN and cervical cancer was also a significant independent predictor of willingness to perform HPV self-sampling, as was having travelled longer distance to attend gynecologic follow-up. Participants with lower income and without completed university education expressed significantly higher confidence in HPV self-sampling and lower confidence in Papanicolaou smears than the other women. To the best of our knowledge, this is the first study to examine the views of women treated for high-grade CIN vis-à-vis HPV self-sampling. The latter is an acceptable option for the vast majority of this cohort of women.

Although the functional merits of preserving cervical nerves in neck dissection for head and neck cancer have been reported, the oncologic safety has not yet been determined. Therefore, the purpose of this study was to evaluate the safety of cervical nerve preservation. A retrospective chart review was performed on patients with head and neck cancer who had been treated by neck dissection between 2009 and 2014 at Kyoto Medical Center. Management of cervical nerves and clinical results were analyzed. A total of 335 sides of neck dissection had been performed in 222 patients. Cervical nerves were preserved in 175 neck sides and resected in 160 sides. The 5-year overall survival (OS) rate calculated by the Kaplan-Meier method was 71%. The 5-year neck control rate was 95% in cervical nerve preserved sides and 89% in cervical nerve resected sides. Preserving cervical nerves in neck dissection is oncologically safe in selected cases. © 2017 Wiley Periodicals, Inc.

Cervical cancer screening rates remain suboptimal among women in South Africa (SA), where cervical cancer prevalence is high. The rollout of HIV-related services across SA may provide a means to deliver cervical cancer screening to populations with limited access to healthcare systems. In this mixed methods study, psychosocial factors influencing cervical cancer prevention and perceptions of the provision of Pap smears in HIV care settings were examined. Structured interviews were conducted with women (n=67) from a municipal housing estate in Durban, SA. Key informants (n=12) also participated in semi-structured interviews. Findings revealed that participants had low cervical cancer knowledge, but desired more information. Relevant themes included the normalization of HIV and beliefs that cervical cancer might be worse than HIV. A comprehensive community clinic was desired by most, even if HIV-positive patients were treated there. This study provides important insight into integrating cervical cancer screening with HIV clinics, which may increase cancer screening among South African women. PMID:25654190

Laminoplasty Techniques for the Treatment of Multilevel Cervical Stenosis

Laminoplasty is one surgical option for cervical spondylotic myelopathy. It was developed to avoid the significant risk of complications associated with alternative surgical options such as anterior decompression and fusion and laminectomy with or without posterior fusion. Various laminoplasty techniques have been described. All of these variations are designed to reposition the laminae and expand the spinal canal while retaining the dorsal elements to protect the dura from scar formation and to preserve postoperative cervical stability and alignment. With the right surgical indications, reliable results can be expected with laminoplasty in treating patients with multilevel cervical myelopathy. PMID:22496982

We report the case histories of two patients treated in our unit for cervical radiculopathy by anterior cervical discectomy and BOP grafting. Both grafts disintegrated within 6 weeks of insertion resulting in increased neurological deficit from cervical cord compression. At reoperation fibres from the grafts were found to have separated and the larger fragments had extruded into the vertebral canal. No evidence of infection was seen, but a foreign body reaction was found in one case. Following graft removal the patients improved symptomatically although one was left with permanent mild biceps weakness.

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 (p<0.0001) and NDI (p<0.0001). Changes were still significant at 4-week follow-up. A 50% reduction in symptoms was scored for 15 of the 17 symptoms scored. Favourable results were seen in nearly 90% of cases. These results show that acupuncture treatment to the cervical region may be effective as a conservative therapy for treating CSR.

The Halo Vest method is a non-invasive treatment of cervical spine fractures. It is successfully applied in adults, which is supported by numerous studies, but has rarely been used among children and young people. There is little published research in this field. The aim of the paper is to present the effectiveness of Halo Vest external fixation in children and to evaluate the complication rate of this method. A retrospective study of 6 patients with cervical spine fractures with an average age of 13.3 years (range: 10 to 17 years) treated with Halo Vest external fixation between 2004 and 2013. The type and cause of fracture, treatment outcome and complications were evaluated. The average duration of follow-up was 55 months. In 5 cases, the treatment result was satisfactory. In one case, there were complications in the form of an external infection around the cranial pins. 1. The Halo Vest system can be applied as a non-operative method of treating cervical spine fractures in children and young people. 2. The criteria of eligibility for specific types of cervical spine fracture treatment in children and young people require further investigation, especially with regard to eliminating complications.

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

To study the analgesic mechanism of Bitongxiao (BTX, a Chinese herbal decoction) in treating neck pain due to cervical spondylitis (CS). BTX and Jingfukang (JFK) granule were used to treat the treated and the control group separately in 102 CS cases. Plasma leucine enkephalin (LEK), substance P (SP) and prostaglandin E2 (PGE2) before and after treatment were assayed by radioimmunoassay (RIA). Twelve patients in the treated group were clinically cured, 36 markedly effectively, 3 effectively and 1 ineffectively, while in the control group they were 5, 33, 14 and 0 cases respectively. The cured and marked effective rate in the treated group was 92.3%, while that in the control group 72.0%. After treatment the pain score (VAS) of both groups were significantly reduced, but the reduction was higher in the treated group than that in the control. Before treatment, plasma LEK in all patients was abnormally low, but after treatment, it raised obviously more in the treated group than that in the control (P < 0.05). Plasma SP of both groups were obviously elevated, and PGE2 revealed unaltered after treatment. BTX has strong, fast-acting and long-lasting analgesic effect with no side-effects, it could elevate the lowered plasma LEK level in cervical spondylitis patients and increase plasma SP level. The analgesic mechanism of BTX might be associated with its effect on LEK, SP or other endorphins, directly acting on the pain modulation system.

Cervical spondylosis is a degenerative disease of cervical spine. The conventional management offered in this condition focuses upon pain, muscle relaxation and restoration of movements. This approach however has not been found adequate in many cases. This is a case of cervical spondylosis treated with naturopathy and yogic practices in an OP set up. Earlier to this treatment, the patient was on conventional medicine. The patient was given naturopathy treatments in form of cold spinal pack followed by other procedures and some yogic practices consisting of asanas, pranayam and relaxation for 30 minutes for a period of one month with an improvement in symptoms. The present case report showed encouraging effects of naturopathic and yogic intervention on cervical spondylosis.

To observe antisepsis, anti-swelling, and therapeutic effects of Fuxiye (FXY), a Chinese medical lotion for external wash in treating vaginitis model rats. The cervicitis rat model was induced by agar plate diffusion, ear auricle swelling induced by dimethylbenzene, and chemical stimulus. The in vitro antibiotic actions of FXY were observed. Besides, its effects on the swelling and inflammation in model rats were also observed. FXY at 25 mg/mL could completely inhibit the growth of Pseudomonas aeruginosa, Escherichia coli, pyogenic Streptococcus, and Streptococcus agalactiae. FXY at 50 mg/mL could completely inhibit the growth of Staphylococcus aureus and Candida albicans. It obviously restrained dimethylbenzene induced ear auricle swelling. It significantly alleviated cervicitis induced by chemical stiumli. FXY showed better effects on antisepsis, anti-inflammation, and treating cervicitis.

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

Survivin is strongly overexpressed in the vast majority of cancers. Initial investigations suggest a role for Survivin in radiation resistance. In this study, we investigate the effect of Survivin expression on clinical outcome and its relationship to tumor oxygenation parameters, expression of Hif-1alpha and anemia in patients with advanced cervical cancers treated with radiotherapy. Biopsies of 44 patients with cervical cancers (Stage IIB: n=9; Stage IIIB: n=31; Stage IVA: n=4) treated with radiotherapy were assessed by immunochemistry for expression of Survivin. Relation of Survivin to pretreatment tumor oxygenation parameters (HF5, pO(2)), hemoglobin (hb) level, Hif-1alpha expression and clinical parameters were investigated. Survivin expression was detected in all tumors of the 44 patients. Seven showed a strong expression and 37 have moderate Survivin expression. Patients whose tumors showed moderate Survivin expression had a 5-year overall survival of 66%. However, only one of the seven patients with strong Survivin expression was alive 45 months after treatment. In a Cox regression analysis, Survivin expression was correlated to poor overall survival (p=0.02, RR=3.3). There was no relationship between Survivin expression and pO(2) or HF5, but rather an inverse correlation with hemoglobin level (p=0.04). Furthermore, for six of the seven tumors with a high Survivin expression, Hif-1alpha was detected. Survivin protein expression is linked with anemia and prognosis in advanced cervical carcinoma of patients treated by radiotherapy.

Non-cytology-based screen-and-treat approaches for cervical cancer prevention have been developed for low-resource settings, but few have directly addressed efficacy. To determine the safety and efficacy of 2 screen-and-treat approaches for cervical cancer prevention that were designed to be more resource-appropriate than conventional cytology-based screening programs. Randomized clinical trial of 6555 nonpregnant women, aged 35 to 65 years, recruited through community outreach and conducted between June 2000 and December 2002 at ambulatory women's health clinics in Khayelitsha, South Africa. All patients were screened using human papillomavirus (HPV) DNA testing and visual inspection with acetic acid (VIA). Women were subsequently randomized to 1 of 3 groups: cryotherapy if she had a positive HPV DNA test result; cryotherapy if she had a positive VIA test result; or to delayed evaluation. Biopsy-confirmed high-grade cervical cancer precursor lesions and cancer at 6 and 12 months in the HPV DNA and VIA groups compared with the delayed evaluation (control) group; complications after cryotherapy. The prevalence of high-grade cervical intraepithelial neoplasia and cancer (CIN 2+) was significantly lower in the 2 screen-and-treat groups at 6 months after randomization than in the delayed evaluation group. At 6 months, CIN 2+ was diagnosed in 0.80% (95% confidence interval [CI], 0.40%-1.20%) of the women in the HPV DNA group and 2.23% (95% CI, 1.57%-2.89%) in the VIA group compared with 3.55% (95% CI, 2.71%-4.39%) in the delayed evaluation group (P<.001 and P = .02 for the HPV DNA and VIA groups, respectively). A subset of women underwent a second colposcopy 12 months after enrollment. At 12 months the cumulative detection of CIN 2+ among women in the HPV DNA group was 1.42% (95% CI, 0.88%-1.97%), 2.91% (95% CI, 2.12%-3.69%) in the VIA group, and 5.41% (95% CI, 4.32%-6.50%) in the delayed evaluation group. Although minor complaints, such as discharge and bleeding, were common after cryotherapy, major complications were rare. Both screen-and-treat approaches are safe and result in a lower prevalence of high-grade cervical cancer precursor lesions compared with delayed evaluation at both 6 and 12 months.

Retrospective study. To report the efficacy of anterior cervical decompression and fusion surgery as treatment method for cervicogenic headache (CeH). The exact diagnostic criteria and optimal treatment of CeH is still under investigation. A total of 34 consecutive patients (mean age 55.8 y) with CeH (in addition to cervical stenosis symptomatology) resistant to nonoperative treatment were treated by anterior cervical decompression and fusion from 1 up to 3 levels and were followed for at least 1 year. Clinical visual analog pain scale for headache, patient satisfaction index as well as radiographic examinations (flexion-extension radiographs and, when diagnosis of fusion status was uncertain, computed tomography) were documented for all patients at regular intervals. Statistical comparisons of outcome measures between different time points of examinations were performed. All patients reported relief of their CeH with mean (range) visual analog pain scale scores as 8.1 (3-9), 2.4 (0-4), and 3.1 (0-5) preoperatively, at 2 months postoperatively, and at the final follow-up, respectively. There was a significant improvement (P<0.001) of visual analog pain scale score between before surgery and at 2 months postoperatively or at the last follow-up. Thirty patients (88%) reported satisfied with their treatment, whereas 4 patients (12%) were not satisfied with surgery. No major surgical complication was seen and only 1 patient had symptomless pseudoarthrosis. CeH when associated with cervical spinal stenosis of the subaxial spine can improve when stenosis is treated with anterior cervical discectomy and fusion.

A variety of bone graft substitutes, interbody cages, and anterior plates have been used in cervical interbody fusion, but no controlled study was conducted on the clinical performance of β-tricalcium phosphate (β-TCP) and the effect of supplemented anterior plate fixation. The objective of this prospective, randomized clinical study was to evaluate the effectiveness of implanting interbody fusion cage containing β-TCP for the treatment of cervical radiculopathy and/or myelopathy, and the fusion rates and outcomes in patients with or without randomly assigned plate fixation. Sixty-two patients with cervical radiculopathy and/or myelopathy due to soft disc herniation or spondylosis were treated with one- or two-level discectomy and fusion with interbody cages containing β-TCP. They were randomly assigned to receive supplemented anterior plate (n = 33) or not (n = 29). The patients were followed up for 2 years postoperatively. The radiological and clinical outcomes were assessed during a 2-year follow-up. The results showed that the fusion rate (75.0%) 3 months after surgery in patients treated without anterior cervical plating was significantly lower than that (97.9%) with plate fixation (P < 0.05), but successful bone fusion was achieved in all patients of both groups at 6-month follow-up assessment. Patients treated without anterior plate fixation had 11 of 52 (19.2%) cage subsidence at last follow-up. No difference (P > 0.05) was found regarding improvement in spinal curvature as well as neck and arm pain, and recovery rate of JOA score at all time intervals between the two groups. Based on the findings of this study, interbody fusion cage containing β-TCP following one- or two-level discectomy proved to be an effective treatment for cervical spondylotic radiculopathy and/or myelopathy. Supplemented anterior plate fixation can promote interbody fusion and prevent cage subsidence but do not improve the 2-year outcome when compared with those treated without anterior plate fixation.

Tracheal resection or placement of airway prostheses (stents, tracheostomy tubes, or T tubes) are techniques currently used to treat severe cervical tracheomalacia. We have developed a new technique to secure a polypropylene splint to the posterior membrane of the cervical trachea in a patient with diffuse, acquired tracheobronchomalacia. This novel posterior tracheoplasty avoids anastomotic and intraluminal adverse events that may occur with existing techniques. Copyright © 2016 The Society of Thoracic Surgeons.

Cervical total disc replacement was developed to preserve motion and reduce adjacent-level degeneration relative to fusion, yet concerns remain that total disc replacement will lead to altered facet joint loading and long-term facet joint arthrosis. This study is intended to evaluate changes in facet contact force, pressure and surface area at the treated and superior adjacent levels before and after discectomy, disc replacement, and fusion. Ten fresh-frozen human cadaveric cervical spines were potted from C2 to C7 with pressure sensors placed into the facet joints of C3-C4 and C4-C5 via slits in the facet capsules. Moments were applied to the specimens to produce axial rotation, lateral bending and extension. Facet contact force and pressure were measured at both levels for intact, discectomy at C4-C5, disc replacement with ProDisc-C (Synthes Spine, West Chester, Pennsylvania, USA) at C4-C5, and anterior discectomy and fusion with Cervical Spine Locking Plate (Synthes Spine, West Chester, Pennsylvania, USA) at C4-C5. Facet contact area was calculated from the force and pressure measurements. An analysis of variance was used to determine significant differences with P-values <0.05 indicating significance. Facet contact force was elevated at the treated level under extension following both discectomy and disc replacement, while facet contact pressure and area were relatively unchanged. Facet contact force and area were decreased at the treated level following fusion for all three loading conditions. Total disc replacement preserved facet contact force for all scenarios except extension at the treated level, highlighting the importance of the anterior disco-ligamentous complex. This could promote treated-level facet joint disease. Copyright © 2017 Elsevier Ltd. All rights reserved.

Rare complication after thyroidectomy-cervical esophageal stenosis: a case report and literature review.

PubMed

Peng, Hanwei; Wang, Steven J; Li, Weixiong

2014-10-11

The most common complications after thyroidectomy are injuries associated with the recurrent laryngeal nerve and parathyroid gland. Cervical esophagus perforation is an exceptionally rare complication after thyroidectomy; it can usually be resolved by conservative care. Cervical esophageal stenosis secondary to intraoperative esophageal injury during thyroidectomy is much rarer and has not been reported in the literature to date. We report a case of esophageal stenosis following thyroidectomy performed at a peripheral hospital. The patient initially underwent a thyroidectomy for papillary thyroid carcinoma involving the cervical esophagus; esophageal perforation was noted intraoperatively, and closed using three number 4 silk sutures. Cervical esophageal stenosis subsequently developed after conservative care. The patient was successfully treated with cervical esophagectomy and reconstruction using a tubed forearm free flap after a failed attempt at endoscopic recanalization. This case is discussed in conjunction with a review of the literature.

Pirarubicin (THP) is a newer generation anthracycline anticancer drug. In the clinic, THP and THP-based combination therapies have been demonstrated to be effective against various tumors without severe side effects. However, previous clinical studies have shown that most patients with cervical cancer are not sensitive to THP treatment, and the associated mechanisms are not clear. Consistent with the clinical study, we confirmed that cervical cancer cells were resistant to THP in vitro and in vivo. Our data demonstrated that THP induced a protective macroautophagy/autophagy response in cervical cancer cells, and suppression of this autophagy dramatically enhanced the cytotoxicity of THP. By scanning the mRNA level change of autophagy-related genes, we found that the upregulation of ATG4B (autophagy-related 4B cysteine peptidase) plays an important role in THP-induced autophagy. Moreover, THP increased the mRNA level of ATG4B in cervical cancer cells by promoting mRNA stability without influencing its transcription. Furthermore, THP triggered a downregulation of MIR34C-5p, which was associated with the upregulation of ATG4B and autophagy induction. Overexpression of MIR34C-5p significantly decreased the level of ATG4B and attenuated autophagy, accompanied by enhanced cell death and apoptosis in THP-treated cervical cancer cells. These results for the first time reveal the presence of a MIR34C-5p-ATG4B-autophagy signaling axis in THP-treated cervical cancer cells in vitro and in vivo, and the axis, at least partially, accounts for the THP nonsensitivity in cervical cancer patients. This study may provide a new insight for improving the chemotherapeutic effect of THP, which may be beneficial to the further clinical application of THP in cervical cancer treatment.

C7 pars fracture subadjacent to C7 pedicle screw instrumentation at the caudal end of a posterior cervical instrumentation construct.

2014-07-01

We report a case of a C7 pars fracture subadjacent to C7 pedicle screw instrumentation at the caudal end of posterior cervical instrumentation construct. To date, posterior cervical instrumentation has been "off label"; however, the US Food and Drug Administration is considering approving label indication of such instrumentation for this common surgical practice. Complications related to the techniques are reported to be relatively low. We know of no previous reports of pars fractures occurring subadjacent to such instrumentation. A 43-year-old man underwent posterior C5-C7 instrumented fusion. Postoperatively, the patient experienced cervical spine injury after a mechanical fall down stairs. Work-up detected bilateral C7 pars fractures subadjacent to the posterior instrumentation construct. After we treated the pars fracture with distal extension of the posterior fusion to the level of T2, the patient progressed to union and marked improvement of initial clinical symptoms that was maintained 2.5 years after posterior instrumentation. To our knowledge, a C7 pars fracture subadjacent to posterior cervical instrumentation construct has not been reported. We hypothesize that the pars may have been vulnerable to fracture because of excessive bone resection during foraminotomy or decortication. This complication was successfully treated by extending the fusion caudally.

Oral sex is a risk factor for human papillomavirus-associated nasopharyngeal carcinoma in husbands of women with cervical cancer.

Sexually transmitted human papillomavirus (HPV) is etiologically related to cervical carcinoma and a distinct subset of cancers of the nasopharyngeal tract. We report 2 patients with HPV-associated cervical cancer and synchronous diagnoses of HPV-related head and neck cancer of their husbands. These patients had active oral sex for more than 20 years. The first patient was a 64-year-old woman who had an abnormal Papanicolaou smear and was found to have squamous cell carcinoma of the cervix on cervical punched biopsy. Her husband was diagnosed with laryngeal squamous cell carcinoma 1 year previously, and was treated with total laryngectomy and adjuvant radiation. HPV-16 DNA was detected in both their tumor specimens using polymerase chain reaction. The other patient was a 50-year-old female with cervical carcinoma treated surgically and with concurrent chemo-radiotherapy. HPV-31 DNA was detected in her tumor specimen. Three years later, her husband presented with nasopharyngeal carcinoma, although not a tobacco or alcohol user. HPV-18 DNA was detected in his tumor specimen.These findings strongly suggest that HPV may play a major role in the carcinogenesis of urogenital and nasopharyngeal tumors and the transmission potential of orogenital sex.

Despite the success of arsenic trioxide (ATO) in treating haematological malignancies, its potential to treat solid tumours has not been fully exploited, owing to its dose-limiting toxicity and poor pharmacokinetics. In order to overcome this hurdle, liposomal encapsulation of the drug with different surface charges (neutral, negative, and positive) and sizes (100, 200 and 400 nm) were synthesised and tested on human papilloma virus (HPV)-positive HeLa and HPV-negative HT-3 cervical cancer cell lines. Two epithelial cell lines-human keratinocytes (HK) and human colon cells (CRL-1790)-were used as controls. The synthesised liposomes were tested for their physico-chemical characteristics, drug loading efficiency, and toxicity on the studied cell lines. Neutral liposomes of 100 nm in size were the chosen formulation for delivering ATO into the studied cells, as they showed the least intrinsic cytotoxicity and the highest loading efficiency. The findings demonstrated that the optimised formulation of liposomes was an effective drug delivery method for HPV-infected cervical cancer cells. Furthermore, the toxicity vs. uptake ratio was highest for HeLa cells, while a reduced or minimal toxic effect was observed for non-HPV-infected cervical cancer cells and control cells. These findings may provide a promising therapeutic strategy for effectively managing cervical cancers.

2016-02-01

To summarize the literature on options of management of patients treated for locally advanced cervical cancers with a specific focus on resource-constrained settings where brachytherapy is not available. A Medline search was performed to summarize studies about treatment approaches including neoadjuvant chemotherapy, primary surgery for bulky cervical cancer, and chemoradiation followed by surgery. Summaries are by treatment approaches that are relevant to resource-constrained settings. There are a lack of studies performed on neoadjuvant chemotherapy in low-resource settings. Primary surgery followed by chemoradiation therapy for selected patients with bulky cervical cancer is a feasible option. The disadvantage is the potential increase in treatment complications. Chemoradiation without brachytherapy followed by surgery has been found to have equivalent outcomes and is associated with acceptable morbidity. In resource-constrained settings where brachytherapy is not available, performing radical hysterectomy after chemoradiation therapy without brachytherapy has been shown to produce equivalent outcomes. It seems reasonable to adopt a modified therapeutic protocol of chemoradiation followed by extrafascial hysterectomy as an alternative treatment option in low-resource countries where brachytherapy is not readily available.

This study aimed at determining if tumor-free distance (TFD) from outermost layer of cervix predicts surgicopathologic factors and outcome in surgically treated cervical cancer patients. One hundred sixteen surgically treated cervical squamous cell carcinomas between 1991 and 2010 with FIGO stage IB/2A were identified and re-evaluated histologically regarding the TFD. TFD was defined as the distance between outermost layer of cervix and deepest cervical stromal invasion. Depth of invasion (DOI) and TFD were expressed as continuous variables and compared with traditional surgicopathologic variables and survival to determine their prognostic significance. The mean DOI was 10.3 mm and the mean TFD was 4.2 mm. The most common stage was IB1 (60 patients, 51.7 %). The mean number of removed pelvic lymph nodes was 32.2 (median 30; range 8-78). Positive pelvic lymph nodes were found in 27 (23 %) of the patients. Sixty-eight patients had lymphovascular space involvement (LVSI). Sixty-eight patients (59 %) received postoperative radiotherapy where the following items were present: tumor diameter >4 cm, positive lymph nodes, LVSI and positive surgical margins. With the median follow-up of 53 months (3-219 months); 14 patients had local and 13 patients had distant metastases (5 of the patients had both at the time of recurrence). With logistic regression analysis, TFD was a predictor of pelvic lymph involvement (p = 0.028) and LVSI (p = 0.008) while DOI was a predictor of LVSI (p = 0.044). In Cox regression analysis, increased TFD was associated with improved disease-free survival (DFS) (p = 0.007). DFS curves (for TFD cut off value 2.5 mm) according to Kaplan-Meier were found to be statistically significant (log rank test = 0.002). The results indicate that TFD is predictive of pelvic lymph node involvement, LVSI and patient outcome in surgically treated cervical cancer patients. However, prospective measurement of TFD is still necessary to determine its value in clinical practice.

With an aim to investigate the impact of Human Papilloma Virus (HPV) 16/18 infection on clinical outcomes in locally advanced cervical cancers treated with radical radio (chemo) therapy, we undertook this prospective study. Between May 2010 and April 2012, 150 histologically proven cervical cancer patients treated with radio (chemo) therapy were accrued. Cervical biopsies/brushings were collected at pre-treatment, end of treatment and at 3 monthly intervals up to 24months. Quantitative estimation of HPV 16/18 was done using real-time polymerase chain reaction (RT-PCR) and correlated with various clinical end-points. Out of 150 patients accrued, 135 patients were considered for final analysis. Pre-treatment HPV16/18 DNA was detected in 126 (93%) patients, with HPV-16 present in 91%. The mean log (±SD) HPV-16 and HPV-18 viral load at pre-treatment was 4.76 (±2.5) and 0.14 (±2.1) copies/10ng of DNA, respectively. Though significant decline in viral load was observed on follow-ups (p<0.0001); by 9-month follow-up, 89 (66%) patients had persistence of HPV infection. Patients with persistent HPV 16/18 infection had a significantly higher overall and loco-regional relapses [44/89 (49%) and 29/89 (32%)] as compared to HPV clearance by 9months [12/43 (28%) and 5/43 (11%)] with p=0.024 and p=0.02, respectively. Also, persistent HPV infection by 24-month showed a significant impact on loco-regional control (LRC) and recurrence-free survival (RFS). In locally advanced cervical cancers treated with radical radio (chemo) therapy, persistent HPV 16/18 infection is significantly high in immediate post-treatment period and correlated with higher loco-regional, overall relapses and was also associated with early relapses.

Cervical cancer is the second most common cancer diagnosed during pregnancy. Conservative management is possible, and different options should be discussed with patients. The main decision parameters are stage of disease, lymph node status, trimester of pregnancy and wishes of the patient. We reviewed our experience on cases of early-stage cervical cancer discovered during pregnancy and treated with different options of fertility-sparing management. Between 1990 and 2010, 5 patients with early-stage cervical cancer diagnosed during pregnancy were referred to our department for fertility-sparing treatment. The mean age at diagnosis was 28.6 years (range, 26-30 years). The stages of the tumors according to the International Federation of Gynecology and Obstetrics were IA2 in 2 women and IB1 in 3 women. The histological type was squamous carcinoma in 3 cases and adenocarcinoma in 2 cases. All patients willing to preserve their fertility were treated with vaginal radical trachelectomy (VRT) and pelvic lymph nodes dissection (PLN-D). Three procedures were performed in the first trimester: 1 patient was treated with medical abortion and then VRT and PLN-D, 2 patients were submitted to VRT and PLN-D during the first trimester, and 1 patient's case was complicated by spontaneous abortion. One patient was observed during the second trimester (20 weeks of gestation) and treated with VRT and PLN-D during pregnancy. Because this patient had pelvic lymph nodes positive for cancer, a cesarean delivery (CD) with radical hysterectomy and para-aortic lymph nodes dissection was performed followed by chemoradiotherapy. The last patient was evaluated during the third trimester of her pregnancy. Treatment included CD followed by VRT and PLN-D, which was delayed, to allow fetal maturity. Diagnosis of cervical cancer can occur during pregnancy. Different options of fertility-sparing treatment can be discussed on the basis of several factors: tumor stage, gestational age, and the patient's desire regarding fertility and pregnancy sparing.

[Purpose] To present a case of the therapeutic reversal of a cervical kyphosis into a lordosis in a patient who presented with neck pain and headaches. [Subject and Methods] A 24-year-old male irritated his neck while dancing. Upon examination it was revealed he had an excessive, 45 mm forward head translation and a 15° cervical kyphosis from C3-C6. The patient was treated with Chiropractic BioPhysics ® methods aimed at restoring the cervical lordosis by mirror image ® , neck extension exercises, cervical extension traction, and spinal manipulative therapy. [Results] After two weeks of treatments the patient reported a complete resolution of neck pain. After 24 treatments over 10-weeks, a lateral radiograph demonstrated the restoration of a cervical lordosis and a complete reduction of forward head translation. [Conclusion] This case demonstrates that a cervical kyphosis may be reversed into a lordosis in as little as 10-weeks by specific care incorporating cervical extension protocols. This case also supports the biomechanical literature that suggests those with cervical kyphosis may be predisposed to spinal injury. We suggest that correcting even asymptomatic patients with obvious cervical spine deformity should be accomplished prior to future injury and/or degenerative changes.

Objective Cervical cancer is a preventable disease which causes significant morbidity and mortality, particularly in developing countries. While technology for early detection continues to improve, prevention programs suffer from significant barriers. Community Based Participatory Research is an approach to research which focuses on collaboration with the community to surmount these barriers. The objective of this study was to evaluate the utility of Community Based Participatory Research techniques in a mother-child screen/treat and vaccinate program for cervical cancer prevention in Manchay, Peru. Methods/materials HPV self-sampling and cryotherapy were utilized for the screen/treat intervention, and the Gardasil vaccine was utilized for the vaccine intervention. Community health workers from Manchay participated in a 3-day educational course, designed by the research team. The community health workers then decided how to implement the interventions in their community. The success of the program was measured by: 1) the ability of the community health workers to determine an implementation plan, 2) the successful use of research forms provided, 3) participation and retention rates, and 4) satisfaction of the participants. Results 1) The community health workers used a door-to-door approach through which participants were successfully registered and both interventions were successfully carried out; 2) registration forms, consent forms, and result forms were utilized correctly with minimal error; 3) screen/treat intervention: 97% of registered participants gave an HPV sample, 94% of HPV positive women were treated, and 90% returned for 6-month follow-up; vaccine intervention: 95% of registered girls received the 1st vaccine, 97% of those received the 2nd vaccine, and 93% the 3rd; 4) 96% of participants in the screen/treat intervention reported high satisfaction. Conclusion Community Based Participatory Research techniques successfully helped to implement a screen/treat and vaccinate cervical cancer prevention program in Manchay, Peru. These techniques may help overcome barriers to large-scale preventive health-care interventions. PMID:23165314

The success of the program was measured by (1) the ability of the community health workers to determine an implementation plan, (2) the successful use of research forms provided, (3) participation and retention rates, and (4) satisfaction of the participants. (1) The community health workers used a door-to-door approach through which participants were successfully registered and both interventions were successfully carried out; (2) registration forms, consent forms, and result forms were used correctly with minimal error; (3) screen/treat intervention: 97% of registered participants gave an HPV sample, 94% of HPV-positive women were treated, and 90% returned for 6-month follow-up; vaccine intervention: 95% of registered girls received the first vaccine, 97% of those received the second vaccine, and 93% the third; (4) 96% of participants in the screen/treat intervention reported high satisfaction. Community-based participatory research techniques successfully helped to implement a screen/treat and vaccinate cervical cancer prevention program in Manchay, Peru. These techniques may help overcome barriers to large-scale preventive health-care interventions.

The aim of this work was to evaluate the incidence of occult cervical glandular intraepithelial neoplasia (CGIN) and adenocarcinoma of the cervix (AC) in women treated with CO2-laser conization for cervical intraepithelial neoplasia (CIN) or squamocellular cervical cancer (SCC). The medical records of all women with a histological diagnosis of squamous lesions of the uterine cervix (persistent CIN1, CIN2, CIN3 and SCC) who were subsequently treated with CO2-laser conization at our institution, during the period from January 1991 to December 2014, were analyzed in a retrospective case series. Among the 1004 women fulfilling the study inclusion/exclusion criteria, 77 cases (7.7%) of occult glandular lesions (CGIN and AC) were detected on the final cone specimen (48 cases of occult low-grade cervical glandular intraepithelial neoplasia (LCGIN), 25 cases of occult high-grade cervical glandular intraepithelial neoplasia (HCGIN), and four cases of occult "usual-type" AC). No difference in the mean age between women diagnosed with occult glandular lesions and women without occult glandular lesions on the final specimen emerged (39.1±9.3 vs 38.4±9.4, p=0.5). In women with occult LCGIN on cone specimen, mean follow-up of 48 months was reported (range 7-206 months) and no cases of progression to HCGIN or AC were observed. In conclusion, a relatively high rate of occult glandular lesions was found in women treated for squamous lesions. The natural history of CGIN is still uncertain and, in particular, there are some controversies as to whether LCGIN is a precursor lesion of HCGIN or AC. In this context the role of pathologists become very important since the appropriate diagnosis of these lesions could have potential implications in the clinical management of these patients.

Women with HIV face an increased risk of human papillomavirus (HPV) acquisition and persistence, cervical intraepithelial neoplasia, and invasive cervical cancer. Our objective was to determine the cost-effectiveness of different cervical cancer screening strategies among women with HIV in South Africa. We modified a mathematical model of HPV infection and cervical disease to reflect co-infection with HIV. The model was calibrated to epidemiologic data from HIV-infected women in South Africa. Clinical and economic data were drawn from in-country data sources. The model was used to project reductions in the lifetime risk of cervical cancer and incremental cost-effectiveness ratios (ICERs) of Pap and HPV DNA screening and management algorithms beginning at HIV diagnosis, at one-, two-, or three-year intervals. Strategies with an ICER below South Africa's 2016 per capita GDP (US$5,270) were considered 'cost-effective.' HPV testing followed by treatment (test-and-treat) at two-year intervals was the most effective strategy that was also cost-effective, reducing lifetime cancer risk by 56·6% with an ICER of US$3,010 per year of life saved (YLS). Other cost-effective strategies included Pap (referral threshold: HSIL+) at one-, two-, and three-year intervals, and HPV test-and-treat at three-year intervals. Pap (ASCUS+), HPV testing with 16/18 genotyping, and HPV testing with Pap or visual triage of HPV-positive women were less effective and more costly than alternatives. Considering per capita GDP as the benchmark for cost-effectiveness, HPV test-and-treat is optimal in South Africa. At lower cost-effectiveness benchmarks, Pap (HSIL+) would be optimal.This is an open access article distributed under the terms of the Creative Commons Attribution License 4.0 (CC BY), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.

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

Abstract Increased incidence of upper cervical metastases and higher life expectancy resulted in higher operative rates in patients. The purpose of this study was to explore the methods and the clinical outcomes of palliative surgery for cervical spinal metastases. A systematic review of a 15-case series of upper cervical metastases treated with palliative surgery was performed. All cases underwent palliative surgery, including anterior tumor resection and internal fixation in 3 cases, posterior tumor resection and internal fixation in 10 cases, and combined anterior and posterior tumor resection and internal fixation in 2 cases. Patients were followed-up clinically and radiologically after the operation, and visual analog scale (VAS) and activities of daily living scores were calculated. In addition, a literature review was performed and patients with upper cervical spine metastases were analyzed. The mean follow-up period was 12.5 months (range, 3–26 months) in this consecutive case series. The pain was substantially relieved in 93.3% (14/15) of the patients after the operation. The VAS and Japanese Orthopedic Association scores showed improved clinical outcomes, from 7.86 ± 1.72 and 11.13 ± 2.19 preoperatively to 2.13 ± 1.40 and 14.26 ± 3.03 postoperatively, respectively. The mean survival time was 9.5 months (range, 5–26 months). Dural tear occurred in 1 patient. Wound infections, instrumentation failure, and postoperative death were not observed. Among our cases and other cases reported in the literature, 72% of the patients were treated with simple anterior or posterior operation, and only 12% of the patients (3/25) underwent complex combined anterior and posterior operation. Metastatic upper cervical spine disease is not a rare occurrence. Balancing the perspective of patients on palliative surgery concerning the clinical benefits of operation versus its operative risks can assist the decision for surgery. PMID:27149472

Background  Indirect posterior cervical nerve root decompression and fusion performed by placing bilateral posterior cervical cages in the facet joints from a posterior approach has been proposed as an option to treat select patients with cervical radiculopathy. The purpose of this study was to report 2-year clinical and radiologic results of this treatment method. Methods  Patients who failed nonsurgical management for single-level cervical radiculopathy were recruited. Surgical treatment involved a posterior approach with decortication of the lateral mass and facet joint at the treated level followed by placement of the DTRAX Expandable Cage (Providence Medical Technology, Lafayette, California, United States) into both facet joints. Iliac crest bone autograft was mixed with demineralized bone matrix and used in all cases. The Neck Disability Index (NDI), visual analog scale (VAS) for neck and arm pain, and SF-12 v.2 questionnaire were evaluated preoperatively and 2 years postoperatively. Segmental (treated level) and overall C2-C7 cervical lordosis, disk height, adjacent segment degeneration, and fusion were assessed on computed tomography scans and radiographs acquired preoperatively and 2 years postoperatively. Results  Overall, 53 of 60 enrolled patients were available at 2-year follow-up. There were 35 females and 18 males with a mean age of 53 years (range: 40-75 years). The operated level was C3-C4 ( N  = 3), C4-C5 ( N  = 6), C5-C6 ( N  = 36), and C6-C7 ( N  = 8). The mean preoperative and 2-year scores were NDI: 32.3 versus 9.1 ( p  < 0.0001); VAS Neck Pain: 7.4 versus 2.6 ( p  < 0.0001); VAS Arm Pain: 7.4 versus 2.6 ( p  < 0.0001); SF-12 Physical Component Summary: 34.6 versus 43.6 ( p  < 0.0001), and SF-12 Mental Component Summary: 40.8 versus 51.4 ( p  < 0.0001). No significant changes in overall or segmental lordosis were noted after surgery. Radiographic fusion rate was 98.1%. There was no device failure, implant lucency, or surgical reinterventions. Conclusions  Indirect decompression and posterior cervical fusion using an expandable intervertebral cage may be an effective tissue-sparing option in select patients with single-level cervical radiculopathy.

Objective: To evaluate the therapeutic effect of cervical Jiaji electroacupuncture on postoperative intractable hiccup of liver neoplasms. Methods: A total of 39 patients with postoperative intractable hiccup of liver neoplasms in The First Affiliated Hospital of Heilongjiang University of Chinese Medicine from May 2013 to May 2017 were collected and divided into 2 groups randomly. The electroacupuncture group included 20 cases, the control group included 19 cases. Patients in the electroacupuncture group were treated by cervical Jiaji electroacupuncture (located in C3-5, sympathetic ganglion), while the control group were treated by metoclopramide combined with chlorpromazine for three days. The therapeutic effects of two groups were compared and the onset time were recorded. Results: Total effective rates of electroacupuncture group and control group were 95.0% and 47.4%, respectively. The onset time in electroacupuncture group and control group were (14.8±3.3) h and (30.5±3.1) h, respectively ( P <0.01). Ten cases who resisted the control treatment were then treated by electroacupuncture for 3 days, 6 cases were recovered, 3 cases became better, while 1 case demonstrated no response. No serious adverse reactions were appeared in each group. Conclusion: Cervical Jiaji electroacupuncture is an effective and safe treatment for postoperative intractable hiccup of liver neoplasms, and it can be used as a remedy for intractable hiccup patients who don't respond to drug treatment.

Classification and Management of Pediatric Subaxial Cervical Spine Injuries.

Madura, Casey J; Johnston, James M

2017-01-01

Appropriate management of subaxial spine injury in children requires an appreciation for the differences in anatomy, biomechanics, injury patterns, and treatment options compared with adult patients. Increased flexibility, weak neck muscles, and cranial disproportion predispose younger children to upper cervical injuries and spinal cord injury without radiographic abnormality. A majority of subaxial cervical spine injuries can be treated nonoperatively. Surgical instrumentation options for children have significantly increased in recent years. Future studies of outcomes for children with subaxial cervical spine injury should focus on injury classification and standardized outcome measures to ensure continued improvement in quality of care for this patient population.

Coexisting cervical spondylotic myelopathy and bilateral carpal tunnel syndromes.

PubMed

Epstein, N E; Epstein, J A; Carras, R

1989-03-01

In six patients, operations for bilateral carpal tunnel syndromes (CTS) were performed or were about to be performed without the awareness of the presence of underlying cervical spondylo-stenosis. Only later, when symptoms of myeloradiculopathy were recognized, was the diagnosis confirmed and decompressive laminectomy performed. Because the symptoms of CTS may resemble or be masked and accentuated by the cervical disorder, patients with the presumed diagnosis of bilateral CTS should undergo appropriate critical neurologic, electrodiagnostic, and neuroradiologic (magnetic resonance imaging, computed tomography, myelo-computed tomography) assessment. If these guidelines are followed, the radiculopathy caused by cervical pathology will be appropriately recognized and treated, possibly averting the need for carpal tunnel decompression or modifying treatment.

A 53-year-old male developed cervical esophageal stenosis after esophageal bypass surgery using a right colon conduit. The esophageal bypass surgery was performed to treat multiple esophageal strictures resulting from corrosive ingestion three years prior to presentation. Although the patient underwent several endoscopic stricture dilatations after surgery, he continued to suffer from recurrent esophageal stenosis. We planned cervical patch esophagoplasty with a pedicled skin flap of sternocleidomastoid (SCM) muscle. Postoperative recovery was successful, and the patient could eat a solid meal without difficulty and has been well for 18 mo. SCM flap esophagoplasty is an easier and safer method of managing complicated and recurrent cervical esophageal strictures than other operations.

Cervical cancer is one of the most common cancers among women worldwide. It is highly lethal yet can be treated when found in early stage. Thus, early detection is of significant important for early diagnosis of cervical cancer. Exosomes have been used as biomarkers in clinical diagnosis. It is unknown that whether blood exosomes associated with cervical cancer can be detected and if these exosomes can accurately represent the developmental stage of cervical cancer. Mouse models were made out of a relapsed cervical cancer patient's tumour sample for original and recurrent cervical cancer, and gene analysis in both tumours and exosomes in these mouse models were performed. We found that activating transcription factor 1 (ATF1) and RAS genes were significantly up-regulated in tumours of both primary and recurrent cervical cancer mouse model, and they can also be detected in the blood exosomes of the mouse model. Our results indicated that ATF1 and RAS could be potential candidate biomarkers for cervical cancer in early diagnosis. ATF1 and RAS genes were found significantly elevated in tumours of primary and recurrent cervical cancer mouse model, and they were also detected in the blood exosomes. Therefore, ATF1 and RAS could be used as a diagnostic marker for cervical cancer in the future. Copyright © 2017 John Wiley & Sons, Ltd.

Screen-and-treat approaches to cervical cancer prevention are an attractive option for low-resource settings, but data on their long-term efficacy are lacking. We evaluated the efficacy of two screen-and-treat approaches through 36 months of follow-up in a randomized trial. A total of 6637 unscreened South African women aged 35-65 years who were tested for the presence of high-risk human papillomavirus (HPV) DNA in cervical samples underwent visual inspection of the cervix using acetic acid staining and HIV serotesting. Of these, 6555 were randomly assigned to three study arms: 1) HPV-and-treat, in which all women with a positive HPV DNA test result underwent cryotherapy; 2) visual inspection-and-treat, in which all women with a positive visual inspection test result underwent cryotherapy; or 3) control, in which further evaluation or treatment was delayed for 6 months. All women underwent colposcopy with biopsy at 6 months. All women who were HPV DNA- or visual inspection-positive at enrollment, and a subset of all other women had extended follow-up to 36 months (n = 3639) with yearly colposcopy. The endpoint-cervical intraepithelial neoplasia grade 2 or worse (CIN2+)-was analyzed using actuarial life-table methods. All statistical tests were two-sided. After 36 months, there was a sustained statistically significant decrease in the cumulative detection of CIN2+ in the HPV-and-treat arm compared with the control arm (1.5% vs 5.6%, difference = 4.1%, 95% confidence interval [CI] = 2.8% to 5.3%, P < .001). The difference in the cumulative detection of CIN2+ in the visual inspection-and-treat arm compared with the control was less (3.8% vs 5.6%, difference = 1.8%, 95% CI = 0.4% to 3.2%, P = .002). Incident cases of CIN2+ (identified more than 12 months after enrollment) were less common in the HPV-and-treat arm (0.3%, 95% CI = 0.05% to 1.02%) than in the control (1.0%, 95% CI = 0.5% to 1.7%) or visual inspection-and-treat (1.3%, 95% CI = 0.8% to 2.1%) arms. In this trial, a screen-and-treat approach using HPV DNA testing identified and treated prevalent cases of CIN2+ and appeared to reduce the number of incident cases of CIN2+ that developed more than 12 months after cryotherapy.

Anterior cervical discectomy and fusion, total disk replacement and open door laminoplasty have been widely used to treat patients with cervical spondylotic myelopathy and/or radiculopathy. In our clinical practice, many patients with cervical spondylosis also complain of headache, and wish to know if the surgical treatment for cervical spondylosis can also alleviate this symptom. Considering that there is no literature concerning this extra benefit of surgical manipulation on cervical spondylosis, we have carried out this retrospective study. Among the patients treated with anterior cervical discectomy and fusion, total disk replacement and open door laminoplasty in our institute for cervical spondylotic myelopathy and/or radiculopathy between February 2002 to March 2011, 108 of whom that have complained about headache at the same time were included in this study. Those patients were followed by 25 to 145 months. Severity of headache before the surgery and at the last follow up was recorded by VAS pain scores and compared among the patients with different surgical methods using SPSS17.0 software. One way ANOVA was used to compare VAS scores between the groups, paired sample t-tests were used to compare the differences in a group at different time points. Headache was significantly alleviated in all groups (P < 0.01). Respectively, 75.0% of the patients in the ACDF group, 84.6% of the patients in the TDR group and 82.2% of the patients in the laminoplasty group were significantly relieved of the headache after the surgery. No significant differences were found with the VAS score at the last follow up among the groups (P > 0.05). No significant differences were found among the groups comparing the degree of alleviation of VAS scores before and after the surgery (P > 0.05). Considering that all the three procedures in the current study have achieved similar effect on alliviating headache in patients with cevical myelopathy, and that what they have in common was that was the decompression of spinal cord, it can be assumed that the headache associated with cervical spondylosis may be the result of compression on the spinal cord. Anterior cervical discectomy and fusion, total disk replacement and open door laminoplasty can all significantly alleviate headache in patients with cervical spondylotic myelopathy and/or radiculopathy. No surgical technique is better than any other technique on alleviating cervical headache associated with cervical spondylotic myelopathy and/or radiculopathy.

Although the presence of a real or potential cervical spine injury limits the options for emergency airway management, many choices still remain. The otolaryngologist-head and neck surgeon frequently is called on to treat patients with airway emergencies; therefore, familiarity with the risk of spinal cord damage and methods to avoid it when establishing a safe airway constitute important knowledge. Experience with the variety of airway techniques available increases the number of options and decreases the risks of morbidity and mortality for the patient with cervical spine injury.

Adoptive T-cell Therapy Promising for Metastatic Cervical Cancer | Center for Cancer Research

Cancer.gov

Over 4,000 women in the U.S. die from cervical cancer each year. Nearly all cases of the disease are caused by infection with human papilloma viruses (HPVs), particularly strains 16 and 18. Cervical cancer can be prevented with vaccination against HPVs before the initiation of sexual activity and can be detected early with regular screening via the Pap test and/or HPV DNA testing. If the disease progresses to a metastatic state, however, it is generally incurable and difficult to treat with chemotherapy.

Background: Cervical cancer is one of the leading severe malignancies throughout the world. Sophra flavescens alkaloid (SFA) gels, a compound Traditional Chinese Medicine, has been clinically used in China for many years. Its individual active ingredients are matrine and oxymatrine, which has been showed that they can restrain primary tumorigenesis, while the underlying molecular mechanisms of SFA gels in cervical cancer cells remain unclear. Methods: To detect the effect of SFA gels and its active ingredients, CCK-8 assay and colony assay were used on cervical cancer cells proliferation. Transwell assay was used to detect cancer cell migration. Apoptosis and cell cycle arrest were used to detect whether SFA gels effect the cervical cancer cells proliferation. Western blot was used to detect whether SFA gels regulate the cervical cancer cells via the suppression of AKT/mTOR signaling pathway. Results: SFA gels can restrain cervical cancer cell proliferation, inhibit metastasis, induce cell cycle arrest in G2/M phase, induce cellular apoptosis through stimulation of Bax and E-cadherin, and suppression of Bcl-2, cyclin A, MMP2. Further study shows that SFA gels may regulate the cervical cancer cells via the suppression of AKT/mTOR signaling pathway. Conclusions: SFA gels, like its active ingredients, can restrain cervical cancer cells proliferation, suppress cervical cancer cell migration, induce the apoptosis and cell cycle arrest in cervical cancer cells. SFA gels may be a potential anti-tumor therapeutic agent for treating cervical cancer.

Molecular studies have shown that oncogenic genotypes of human papillomavirus (HPV) are the main risk factor for cervical cancer development. Sub-clinical wound does not cause symptoms and is diagnosed by colposcopy or histology, in addition the latent infection is associated with the presence of DNA of the HPV, but when clinical and histological abnormalities are not presented only molecular techniques can detect this infection. To determine if complementary processing with imiquimod, recent medicament with powerful antiviral activity in vitro as in vivo, reduces the cervical persistence of HPV. This study was carried out with 87 patients, who had antecedents of HPV cervical and intraepithelial wound with low degree. Patients were divided as follows: treated with cryotherapy, cervical loop electrosurgical and imiquimod, all with diagnosis by cervical cytology, colposcopy and polymerase chain reaction (PCR) for HPV. At 3, 6 and 12 months after the processing, PCR, cervical cytology and colposcopy control were carried out again. Out of the 87 patients studied, 11% (10) patients treated with cervical cytology were positive for VPH; with colposcopy 8% (7) of patients and with PCR 40% (34) of patients; decreased persistence with combined methods of loop and imiquimod was obtained in 29% (5) patients; however, when utilized imiquimod alone, there were 55% (11) patients with persistence determined by PCR method. Imiquimod appears to be beneficial in 45% of the patients, in contrast with efficacy reported until 85% in genitals and annals warts, in addition, the capacity of eliminating the viruses has been shown, therefore it is possible that its potential effect could be observed long-time. It is evident that the percentages of viral detection are improved for PCR method, compared with indirect methods as cervical cytology and colposcopy, which is favorable when virus serotypes are of high degree of transformation and ablative methods should be conservatives due to fertility motives.

Cervical radiculopathy is a relatively common neurological disorder resulting from nerve root dysfunction, which is often due to mechanical compression; however, inflammatory cytokines released from damaged intervertebral disks can also result in symptoms. Cervical radiculopathy can often be diagnosed with a thorough history and physical examination, but an magnetic resonance imaging or computed tomographic myelogram should be used to confirm the diagnosis. Because of the ubiquity of degenerative changes found on these imaging modalities, the patient's symptoms must correlate with pathology for a successful diagnosis. In the absence of myelopathy or significant muscle weakness all patients should be treated conservatively for at least 6 weeks. Conservative treatments consist of immobilization, anti-inflammatory medications, physical therapy, cervical traction, and epidural steroid injections. Cervical radiculopathy typically is self-limiting with 75%-90% of patients achieving symptomatic improvement with nonoperative care. For patients who are persistently symptomatic despite conservative treatment, or those who have a significant functional deficit surgical treatment is appropriate. Surgical options include anterior cervical decompression and fusion, cervical disk arthroplasty, and posterior foraminotomy. Patient selection is critical to optimize outcome.

Precancerous cervical lesions precede the development of invasive cervical cancer by 10-20 years, making cervical cancer preventable if these lesions are detected and effectively treated. Treatment has evolved in the last few decades and now includes ablative options that can be performed in lower-resource settings where surgical excision is not feasible or routinely available. Gas-based cryotherapy, which freezes cervical tissue to induce localized necrosis, is the most commonly used ablative treatment. However, its implementation in low-resource settings is difficult because the refrigerant gas can be difficult to procure and transport, and is expensive. New cryotherapy devices that do not require an external supply of gas appear promising. Thermal coagulation, which burns cervical tissue to induce necrosis, has become more widely available in the last few years owing to its portability and the feasibility of using battery-powered devices. These two ablative treatments successfully eradicate 75%-85% of high-grade cervical lesions and have minor adverse effects. © 2017 The Authors.

Patients have an increased risk of persistent/recurrent cervical disease if they received treatment for a high-grade squamous intraepithelial lesion (HSIL). Consequently, understanding whether co-testing (human papillomavirus [HPV] DNA testing and cervical cytology) is fully utilised by general practitioners (GPs) is paramount. After consultation with key stakeholders, an anonymous, self-completion questionnaire was developed and disseminated to GPs who had provided cervical cytology. Responses were received from 745 GPs (30.9% response rate). A significant number (34.3%) of GPs were unaware of the use of co-testing (HPV DNA testing and cervical cytology) for the management of patients after HSIL treatment. Additionally, the majority of GPs reported they did not 'always' receive a clear follow-up plan for patients after treatment of an HSIL. GPs require further support and education to ensure successful adoption of co-testing (HPV DNA testing and cervical cytology), specifically, for patients treated for an HSIL.

To study the relationship between nitric oxide within cervical microenvironment and different HPV types as well as the effect of sodium nitroprusside (SNP), a nitric oxide donor, on the proliferation and apoptosis of cervical cancer cell lines. HPV typing test was assessed from 115 women by using high-risk HPV (HR-HPV) 21 typing test and the release of cervical nitric oxide (NO) was assessed as nitrate, nitrite in cervical fluid. Cervical NO was then compared between women showing different HPV types. Proliferation of Caski and HeLa cervical cells was determined by methyl thiazolyl tetrazolium (MTT) assay, cell apoptosis was detected by flow cytometry after 24 hours treated by different final concentration of SNP (0.125, 0.25, 0.5, 1.0 and 2.0 mmol/L, respectively). The expressions of HPV E6, E7 gene mRNA and p53 protein were detected by SYBR Green I quantitative real-time PCR and western blot. (1) The cervical NO release of women with HR-HPV was higher compared to that in HPV negative women [(47.6±1.4) µmol/L vs (22.8±0.3) µmol/L; P<0.05]; but there was no statistical difference between low-risk HPV (LR-HPV) group [(24.1±1.2) µmol/L] and control group (P>0.05). (2) After 24 hours treated by different final concentration of SNP, the results shown that SNP could inhibited the proliferation and increased apoptosis rate in Caski and HeLa cells, in which the concentration of SNP≥1.0 mmol/L, there were significantly different (P<0.05), while when SNP≥2.0 mmol/L, the proliferation of cells inhibited seriously. Treated by SNP (1.0 mmol/L) 24 hours, the expressions of HPV18 E6, E7 mRNA in HeLa cells were reduced from 27.362±0.191, 22.962±0.053 to 19.181±0.360, 17.571±0.010 and the protein expression of p53 increased from 1.17±0.03 to 0.23±0.05, there were statistically significant differences between adding SNP group and the control group (P<0.05); but there were no statistically significant differences in HPV16 E6, E7 mRNA and that of p53 in Caski cells (P>0.05). The presence of HR-HPV is associated with an increased release of NO in the human uterine cervix; NO could inhibit the growth and proliferation and enhance the apoptosis of cervical cancer cells, inhibit the expression of HPV18 E6, E7 mRNA in HeLa cells and activate the expression of p53 protein, the mechanism may be due to higher sensitivity of HeLa cells (cervical adenocarcinoma cell) to SNP. The increasing release of NO may play a role in regulating the elimination of HPV in cervical microenvironment, which is a part of mucous membrane immunity.

Poisoning is the second leading cause of injury-related fatality in the USA and the leading cause of cardiac arrest in victims under 40 years of age. The study objective was to define the electrocardiographic (ECG) predictors of adverse cardiovascular events (ACVE) complicating suspected acute poisoning (SAP). This was a case-control study in adults at three tertiary-care hospitals and one regional Poison Control Center. We compared 34 cases of SAP complicated by ACVE to 101 consecutive control patients with uncomplicated SAP. The initial ECG was analyzed for rhythm, intervals, QT dispersion, ischemia, and infarction. ECGs were interpreted by a cardiologist, blinded to study hypothesis and case data. Subjects were 48% male, with mean age 42 +/- 19 years. In addition to clinical suspicion of poisoning in 100% of patients, routine toxicology screens were positive in 77%, most commonly for benzodiazepines, opioids, and/or acetaminophen. Neither the ventricular rate, the QRS duration, nor the presence of infarction predicted the risk of ACVE. However, the rhythm, QTc, QT dispersion, and presence of ischemia correlated with the risk of ACVE. Independent predictors of ACVE based on multivariable logistic regression were prolonged QTc, any non-sinus rhythm, ventricular ectopy, and ischemia. Recursive partitioning analysis identified very low risk criteria (94.1% sensitivity, 96.2% NPV) and high risk criteria (95% specificity). Among patients with SAP, the presence of QTc prolongation, QT dispersion, ventricular ectopy, any non-sinus rhythm, and evidence of ischemia on the initial ECG are strongly associated with ACVE.

This study evaluated ex vivo the influence of the number of gel/LED-laser applications/activations on cervical microleakage of two different barrier materials used for protection during whitening of endodontically treated teeth. Eighty-four canines were instrumented and obturated with epoxy resin sealer. The seal was removed 2 mm beyond the cemento-enamel junction for barrier placement and the teeth were divided into two groups of 40 teeth each: G1, zinc phosphate cement; G2, glass ionomer cement. The two groups were subdivided into 4 subgroups (n=10 each): I) no gel or LED-laser application; II) one gel application and two LED-laser activations; III) two gel applications and four LED-laser activations; IV) three gel applications and six LED-laser activations. The teeth were immersed in India ink for 7 days, decalcified and cleared. Cervical microleakage was quantified with a measurement microscope. Statistical analysis showed that zinc phosphate caused significantly lower microleakage than glass ionomer cement (presented microleakage in all subgroups). However, after two (p<0.01) and three (p<0.001) applications of gel, there was statistially significant microleakage in zinc phosphate barriers. Based on the present results, it can be concluded that cervical barriers with zinc phosphate cement show less cervical microleakage and that two or more applications/activations of gel/LED-laser significantly increase microleakage.

To describe the treatment of a patient with chronic whiplash-associated disorders (WADs) previously unresponsive to multiple physical therapy and chiropractic treatments, which resolved following Clinical Biomechanics of Posture (CBP) rehabilitation methods. A 40-year-old man involved in a high-speed rear-impact collision developed chronic WADs including cervicothoracic, shoulder, and arm pain and headache. The patient was diagnosed with a confirmed chip fracture of the C5 vertebra and cervical and thoracic disk herniations. He was treated with traditional chiropractic and physical therapy modalities but experienced only temporary symptomatic reduction and was later given a whole body permanent impairment rating of 33% by an orthopedic surgeon. The patient was treated with CBP mirror-image cervical spine adjustments, exercise, and traction to reduce forward head posture and cervical kyphosis. A presentation of abnormal head protrusion resolved and cervical kyphosis returned to lordosis posttreatment. His initial neck disability index was 46% and 0% at the end of care. Verbal pain rating scales also improved for neck pain (from 5/10 to 0/10). A patient with chronic WADs and abnormal head protrusion, cervical kyphosis, and disk herniation experienced an improvement in symptoms and function after the use of CBP rehabilitation protocols when other traditional chiropractic and physical therapy procedures showed little or no lasting improvement.

To present our experience of staged correction with multiple cervical hemivertebra resection and thoracic pedicle subtraction osteotomy (PSO) treating a rare and complicated congenital scoliosis. A 14-year-old male presented with progressive torticollis and spine deformity. The malformation developed since birth, and back pain after long-time sitting or exercise arose since 6 months before, which was unsuccessfully treated by physiotherapy. X-ray showed a right cervical curve of 60° and a left compensatory thoracic curve of 90°. Three-dimensional computed tomography (3-D CT) scan revealed three semi-segmented hemivertebrae (C4, C5 and C6) on the right side. Based on our staged strategy, the three consecutive cervical hemivertebrae, as the major pathology causing the deformity, were firstly resected by the combined posterior and anterior approach. Six months later, T6 PSO osteotomy was used to correct the structural compensatory thoracic curve. The cervical curve was reduced to 23° while the thoracic curve to 60° after the first-stage surgery, and the thoracic curve was further reduced to 30° after the second-stage surgery. The radiograph at 5-year follow-up showed that both the coronal and sagittal balance were well restored and stabilized, with the occipital tilt reduced from 12° to 0°. Our strategy may provide an option for similar cases with multiple consecutive cervical hemivertebrae and a large structural compensatory thoracic curve, which proved to achieve excellent correction in both the coronal and sagittal planes with acceptable neurologic risk.

C2-C3 Anterior Cervical Fusion: Technical Report.

Retrospective review of patients at a university hospital. To describe the anterior approach for cervical discectomy and fusion (ACDF) at C2-C3 level and evaluate its suitability for treatment of instability and degenerative disease in this region. The anterior approach is commonly used for ACDF in the lower cervical spine but is used less often in the high cervical spine. We retrospectively reviewed a database of consecutive cervical spine surgeries performed at our institution to identify patients who underwent ACDF at the C2-C3 level during a 10-year period. Demographic data, clinical indications, surgical technique, complications, and immediate results were evaluated. Of the 11 patients (7 female, 4 male; mean age 46 y) identified, 7 were treated for traumatic fractures and 4 for degenerative disk disease. Three patients treated for myelopathy showed improvement in mean Nurick grade from 3.6 to 1.3. Pain was significantly improved in all patients who had preoperative pain. Solid bony fusion was achieved in 5 of 7 patients at 3-month follow-up. Complications included dysphagia in 4 patients (which resolved in 3), aspiration pneumonia, mild persistent dysphonia, and construct failure at C2 requiring posterior fusion. One patient died of a pulmonary embolism 2 weeks postoperatively. ACDF at the C2-C3 level is an option for the treatment of high cervical disease or trauma but is associated with a higher rate of approach-related morbidity. Familiarity with local anatomy may help to reduce complications. ACDF at C2-C3 appears to have a fusion rate similar to ACDF performed at other levels.

This article constructs a map on the translation of knowledge concerning cervical cancer, based on citation networks analysis and the use of Gene Ontology terms and Medical Subject Headings. We identified two areas of research that are poorly interconnected and differ in structure, content, and evolution. One focuses on causes of cancer and the other on patient care. The first research area showed a knowledge translation process where basic research and clinical research are communicated through a set of articles that consolidate human papillomavirus infection as the necessary cause of cervical cancer. The first area aims to prevent HPV infection and the development of cervical cancer, while the second aims to stage and treat the disease.

Kraus, Steve

2007-01-01

Head and orofacial pain originates from dental, neurologic, musculoskeletal, otolaryngologic, vascular, metaplastic, or infectious disease. It is treated by many health care practitioners, such as dentists, oral surgeons, and physicians. The article focuses on the nonpathologic involvement of the musculoskeletal system as a source of head and orofacial pain. The areas of the musculoskeletal system that are reviewed include the temporomandibular joint and muscles of mastication--collectively referred to as temporomandibular disorders (TMDs) and cervical spine disorders. The first part of the article highlights the role of physical therapy in the treatment of TMDs. The second part discusses cervical spine considerations in the management of TMDs and head and orofacial symptoms. It concludes with and overview of the evaluation and treatment of the cervical spine.

Cervical cancer has become the most common cancer affecting women in Africa. Significantly, 85% of these annual deaths occur in the developing world, with the majority being middle-aged women. Research has shown that in sub-Saharan Africa, cervical cancer trends are on the rise in the past two decades because of HIV and this has resulted in an increase in cervical cancer cases among young women. However, little or no information exists that has shown that any of the available treatment methods are more effective than others when it comes to treating cervical cancer in HIV-seropositive women. The aim of this protocol is to offer a plan on how to systematically review cervical cancer treatment methods available for HIV-seropositive women in developing countries. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) statement was used to develop the protocol for the systematic review which will be reported in accordance with the PRISMA guidelines. A number of databases, Embase, MEDLINE, PubMed, CINAHL and Cochrane Library, will be searched for relevant studies, and citation and reference list tracking will be used to search for additional studies. Prospective and retrospective cohort studies, case-control, randomised controlled trials and cross-sectional studies that were carried out in and for the developing world will be eligible for inclusion. Peer-reviewed studies and grey literature examining cervical cancer treatment modalities in HIV-seropositive women will be included. Descriptive statistics and tables will be used to summarise results, and meta-analysis will be used where appropriate. The review findings will provide the current picture of the existing treatment methods being used to treat cervical cancer in HIV-seropositive women in developing countries. The findings might be used for the establishment of evidence-based guidelines for treatment of cervical cancer in seropositive women as well as prompt policy-makers and governments to decide and support future research in a way to find a lasting solution.

Pace mapping has been used to identify the site of origin of focal ventricular arrhythmias. The spatial resolution of pace mapping has not been adequately quantified using currently available three-dimensional mapping systems. The purpose of this study was to determine the spatial resolution of pace mapping in patients with idiopathic ventricular tachycardia or premature ventricular contractions originating in the right ventricular outflow tract. In 16 patients with idiopathic ventricular tachycardia/ectopy from the right ventricular outflow tract, comparisons and classifications of pace maps were performed by two observers (good pace map: match >10/12 leads; inadequate pace map: match < or =10/12 leads) and a customized MATLAB 6.0 program (assessing correlation coefficient and normalized root mean square of the difference (nRMSd) between test and template signals). With an electroanatomic mapping system, the correlation coefficient of each pace map was correlated with the distance between the pacing site and the effective ablation site. The endocardial area within the 10-ms activation isochrone was measured. The ablation procedure was effective in all patients. Sites with good pace maps had a higher correlation coefficient and lower nRMSd than sites with inadequate pace maps (correlation coefficient: 0.96 +/- 0.03 vs 0.76 +/- 0.18, P <.0001; nRMSd: 0.41 +/- 0.16 vs 0.89 +/- 0.39, P <.0001). Using receiver operating characteristic curves, appropriate cutoff values were >0.94 for correlation coefficient (sensitivity 81%, specificity 89%) and < or =0.54 for nRMSd (sensitivity 76%, specificity 80%). Good pace maps were located a mean of 7.3 +/- 5.0 mm from the effective ablation site and had a mean activation time of -24 +/- 7 ms. However, in 3 (18%) of 16 patients, the best pace map was inadequate at the effective ablation site, with an endocardial activation time at these sites of -25 +/- 12 ms. Pace maps with correlation coefficient > or =0.94 were confined to an area of 1.8 +/- 0.6 cm2. The 10-ms isochrone measured 1.2 +/- 0.7 cm2. The spatial resolution of a good pace map for targeting ventricular tachycardia/ectopy is 1.8 cm2 in the right ventricular outflow tract and therefore is inferior to the spatial resolution of activation mapping as assessed by isochronal activation. In approximately 20% of patients, pace mapping is unreliable in identifying the site of origin, possibly due a deeper site of origin and preferential conduction via fibers connecting the focus to the endocardial surface.

Because of the prevalence of methamphetamine abuse worldwide, it is not uncommon for subjects in law enforcement encounters to be methamphetamine-intoxicated. Methamphetamine has been present in arrest-related death cases in which an electronic control device (ECD) was used. The primary purpose of this study was to determine the cardiac effects of an ECD in a methamphetamine intoxication model. Sixteen anesthetized Dorset sheep (26-78 kg) received 0.0 mg/kg (control animals, n = 4), 0.5 mg/kg (n = 4), 1.0 mg/kg (n = 4), or 1.5 mg/kg (n = 4) of methamphetamine hydrochloride as a slow intravenous (IV) bolus during continuous cardiac monitoring. The animals received the following exposures in sequence from a TASER X26 ECD beginning at 30 minutes after the administration of the drug: 1) 5-second continuous exposure, 2) 15-second intermittent exposure, 3) 30-second intermittent exposure, and 4) 40-second intermittent exposure. Darts were inserted at the sternal notch and the cardiac apex, to a depth of 9 mm. Cardiac motion was determined by thoracotomy (smaller animals, < or = 32 kg) or echocardiography (larger animals, > 68 kg). Data were analyzed using descriptive statistics and chi-square tests. Animals given methamphetamine demonstrated signs of methamphetamine toxicity with tachycardia, hypertension, and atrial and ventricular ectopy in the 30-minute period immediately after administration of the drug. Smaller animals (n = 8, < or = 32 kg, mean = 29.4 kg) had supraventricular dysrhythmias immediately after the ECD exposures. Larger animals (n = 8, > 68 kg, mean = 72.4) had only sinus tachycardia after the exposures. One of the smaller animals had frequent episodes of ventricular ectopy after two exposures, including runs of delayed onset, nonsustained six- to eight-beat unifocal and multifocal ventricular tachycardia that spontaneously resolved. This animal had significant ectopy prior to the exposures as well. Thoracotomy performed on three smaller animals demonstrated cardiac capture during ECD exposure consistent with previous animal studies. In the larger animals, none of the methamphetamine-intoxicated animals demonstrated cardiac capture. Two control sheep showed evidence of capture similar to the smaller animals. No ventricular fibrillation occurred after the exposure in any animal. In smaller animals (32 kg or less), ECD exposure exacerbated atrial and ventricular irritability induced by methamphetamine intoxication, but this effect was not seen in larger, adult-sized animals. There were no episodes of ventricular fibrillation after exposure associated with ECD exposure in methamphetamine-intoxicated sheep.

We have previously shown that the HIV protease inhibitor lopinavir has selective toxicity against human papillomavirus (HPV)-positive cervical carcinoma cells via an unknown mechanism. SiHa cervical carcinoma cells were stably transfected with the proteasome sensor vector pZsProSensor-1 to confirm lopinavir inhibits the proteasome in these cells. The Panorama Xpress profiler 725 antibody array was then used to analyse specific changes in protein expression in lopinavir-treated versus control untreated SiHa cells followed by PCR and western blotting. Colorimetric growth assays of lopinavir-treated E6/E7 immortalised versus control human keratinocytes were performed. Targeted small interfering RNA gene silencing followed by growth assay comparison of lopinavir-treated/untreated SiHa cells was also used. Lopinavir induced an increase in the fluorescence of pZsProSensor-1 transfected SiHa cells, indicative of proteasomal inhibition. Ribonuclease L (RNASEL) protein was shown to be up-regulated in lopinavir-treated SiHa cells, which was confirmed by PCR and western blot. Targeted silencing of RNASEL reduced the sensitivity of SiHa cells to lopinavir. Selective toxicity against E6/E7 immortalised keratinocytes versus control cells was also seen with lopinavir and was associated with up-regulated RNASEL expression. These data are consistent with the toxicity of lopinavir against HPV-positive cervical carcinoma cells being related to its ability to block viral proteasome activation and induce an up-regulation of the antiviral protein RNASEL. This is supported by the drug's selective toxicity and up-regulation of RNASEL in E6/E7 immortalised keratinocytes combined with the increased resistance to lopinavir observed in SiHa cells following silencing of RNASEL gene expression.

Locally advanced invasive cervical cancer [International Federation of Gynecology and Obstetrics (FIGO) IIB/III] is treated by chemoradiation. The response to treatment is variable within a given FIGO stage. Therefore, the aim of the present study was to evaluate the gene promoter methylation profile and corresponding transcript expression of a panel of six genes to identify genes which could predict the response of patients treated by chemoradiation. In total, 100 patients with invasive cervical cancer in FIGO stage IIB/III who underwent chemoradiation treatment were evaluated. Ten patients developed systemic metastases during therapy and were excluded. On the basis of patient follow-up, 69 patients were chemoradiation-sensitive, whereas 21 were chemoradiation-resistant. Gene promoter methylation and gene expression was determined by TaqMan assay and quantitative real-time PCR, respectively, in tissue samples. The methylation frequency of ESR1, BRCA1, RASSF1A, MLH1, MYOD1 and hTERT genes ranged from 40 to 70%. Univariate and hierarchical cluster analysis revealed that gene promoter methylation of MYOD1, ESR1 and hTERT could predict for chemoradiation response. A pattern of unmethylated MYOD1, unmethylated ESR1 and methylated hTERT promoter as well as lower ESR1 transcript levels predicted for chemoradiation resistance. Methylation profiling of a panel of three genes that includes MYOD1, ESR1 and hTERT may be useful to predict the response of invasive cervical carcinoma patients treated with standard chemoradiation therapy.

We evaluated the effectiveness of transcatheter arterial coil embolization therapy for the treatment of spontaneous hemothorax followed by aneurysm rupture in neurofibromatosis patients. Three patients were treated for massive hemothorax caused by arterial lesions associated with neurofibromatosis. Bleeding episodes were secondary to ascending cervical artery aneurysm and dissection of vertebral artery in 1 patient, and intercostal artery aneurysm with or without arteriovenous fistula in 2 patients. Patients were treated by transarterial coil embolization combined with chest drainage. In 1 patient, the ruptured ascending cervical artery aneurysm was well embolized but, shortly after the embolization, fatal hemorrhage induced by dissection ofmore » the vertebral artery occurred and the patient died. In the other 2 patients, the ruptured intercostal artery aneurysm was well embolized and they were successfully treated and discharged. Transcatheter arterial coil embolization therapy is an effective method for the treatment of spontaneous hemothorax followed by aneurysm rupture in neurofibromatosis patients.« less

Objectives: the aim was to translate and culturally adapt the Adherence Determinants Questionnaire scale for the Portuguese language in the Brazilian context, and to check its reliability and validity to analyze the elements of the adherence of patients to the clinical treatment for breast and cervical cancer. Method: this was a methodological study, carried out in two oncology reference centers. The sample consisted of 198 participants, with 152 being treated for breast cancer and 46 being treated for cervical cancer. The content validation was performed by a committee of experts. The construct validation was demonstrated through factor analysis and the reliability was analyzed using Cronbach's alpha. Results: the committee of experts made the necessary adjustments so that the scale was adapted to the Brazilian context. The factor analysis suggested a reduction from seven to five factors and the maintenance of 38 items similar to those of the original scale. The reliability, investigated through Cronbach's alpha, was .829, showing high internal consistency. Conclusion: it was concluded that the Brazilian version of the Adherence Determinants Questionnaire scale is a valid and reliable instrument that is able to measure the elements of adherence to the treatment for breast and cervical cancer.

This is a cross-sectional study on the use of halovest appliance in the Orthopaedic and Traumatology Department, Kuala Lumpur Hospital from June 1993 to September 1996. Fifty-three patients with cervical spine injuries were treated by halovest stabilization. Majority of cases was caused by motor-vehicle accident; others were fall from height at construction sites, fall at home, hit by falling object and assault. The injuries were Jefferson fracture of C1, odontoid fractures, hangman fractures, open spinous process fracture and fracture body of C2, and fracture, and fracture-dislocation of the lower cervical spines. Majority of patients had hospital stay less than 30 days. The use of the halovest ranges from 4 to 16 weeks and the healing rate was 96%. Two patients of lower cervical spine injury had redislocation and one of them was operated. There was one case of non-union of type II odontoid fracture and treated by posterior fusion. Other complications encountered during halovest treatment were minor. They were pin-site infection, pin-loosening, clamp loosening and neck pain or neck stiffness. This method of treatment enables patient to ambulate early and reduces hospital stay. We found that halovest is easy to apply, safe and tolerable to most of the patients.

Computational intelligence methods, including non-linear classification algorithms, can be used in medical research and practice as a decision making tool. This study aimed to evaluate the usefulness of artificial intelligence models for 5-year overall survival prediction in patients with cervical cancer treated by radical hysterectomy. The data set was collected from 102 patients with cervical cancer FIGO stage IA2-IIB, that underwent primary surgical treatment. Twenty-three demographic, tumor-related parameters and selected perioperative data of each patient were collected. The simulations involved six computational intelligence methods: the probabilistic neural network (PNN), multilayer perceptron network, gene expression programming classifier, support vector machines algorithm, radial basis function neural network and k-Means algorithm. The prediction ability of the models was determined based on the accuracy, sensitivity, specificity, as well as the area under the receiver operating characteristic curve. The results of the computational intelligence methods were compared with the results of linear regression analysis as a reference model. The best results were obtained by the PNN model. This neural network provided very high prediction ability with an accuracy of 0.892 and sensitivity of 0.975. The area under the receiver operating characteristics curve of PNN was also high, 0.818. The outcomes obtained by other classifiers were markedly worse. The PNN model is an effective tool for predicting 5-year overall survival in cervical cancer patients treated with radical hysterectomy.

To compare the therapeutic effects between needle knife therapy combined with rotation traction manipulation and rotation traction manipulation for the treatment of cervical spondylotic radiculopathy. From November 2013 to June 2015, 80 patients with cervical spondylotic radiculopathy meeting the inclusion criteria were divided into two groups randomly:the control group in which 39 patients were treated with rotation traction manipulation, and the treatment group in which 41 patients were treated with needle knife combined with rotation traction manipulation. The patients in the control group were treated once dayly for 2 weeks, which was 1 course. The patients in the treatment group were treated with needle knife firstly once a week for 2 weeks, which was 1 course;then were treated with the same methods as the patients in the control group. The symptoms, signs score and the therapeutic effects of the two groups before and after treatment were observed. After treatment, symptoms and signs scores declined in both groups( P <0.05). The results of the treatment group were better than effects in the control group( P <0.05). In the treatment group, 19 patients got an excellent result, 16 good, 5 fair and 1 bad;while in the control group, 10 patients got an excellent result, 10 good, 16 fair and 3 bad;the results of the treatment group were better than the results of the control group( P <0.01). Needle knife combined with rotation traction manipulation is an effective method for the treatment of cervical spondylotic radiculopathy, which is better than using manipulation method simply. Needle knife therapy has follow advantages:improving local blood circulation, reducing local content of pain substance, increasing production of substances resisting pain, opening channels and collaterals, and make body reaching new static and dynamic balance on the new foundation.

Purpose: Intensity modulated radiation therapy (IMRT), compared with conventional 4-field treatment, can reduce the volume of bone marrow irradiated. Pelvic bone marrow sparing has produced a clinically significant reduction in hematologic toxicity (HT). This analysis investigated HT in Radiation Therapy Oncology Group (RTOG) 0418, a prospective study to test the feasibility of delivering postoperative IMRT for cervical and endometrial cancer in a multiinstitutional setting. Methods and Materials: Patients in the RTOG 0418 study were treated with postoperative IMRT to 50.4 Gy to the pelvic lymphatics and vagina. Endometrial cancer patients received IMRT alone, whereas patients with cervical cancer received IMRTmore » and weekly cisplatin (40 mg/m{sup 2}). Pelvic bone marrow was defined within the treatment field by using a computed tomography density-based autocontouring algorithm. The volume of bone marrow receiving 10, 20, 30, and 40 Gy and the median dose to bone marrow were correlated with HT, graded by Common Terminology Criteria for Adverse Events, version 3.0, criteria. Results: Eighty-three patients were eligible for analysis (43 with endometrial cancer and 40 with cervical cancer). Patients with cervical cancer treated with weekly cisplatin and pelvic IMRT had grades 1-5 HT (23%, 33%, 25%, 0%, and 0% of patients, respectively). Among patients with cervical cancer, 83% received 5 or more cycles of cisplatin, and 90% received at least 4 cycles of cisplatin. The median percentage volume of bone marrow receiving 10, 20, 30, and 40 Gy in all 83 patients, respectively, was 96%, 84%, 61%, and 37%. Among cervical cancer patients with a V40 >37%, 75% had grade 2 or higher HT compared with 40% of patients with a V40 less than or equal to 37% (P =.025). Cervical cancer patients with a median bone marrow dose of >34.2 Gy also had higher rates of grade ≥2 HT than did those with a dose of ≤34.2 Gy (74% vs 43%, P=.049). Conclusions: Pelvic IMRT with weekly cisplatin is associated with low rates of HT and high rates of weekly cisplatin use. The volume of bone marrow receiving 40 Gy and the median dose to bone marrow correlated with higher rates of grade ≥2 toxicity among patients receiving weekly cisplatin (cervical cancer patients). Evaluation and limitation of the volume of bone marrow treated with pelvic IMRT is warranted in patients receiving concurrent chemotherapy.« less

Blunt cerebrovascular injuries (BCVI) carry significant morbidity if not diagnosed and treated early. A high index of clinical suspicion is needed to recognize the injury patterns associated with this condition and to order the requisite imaging studies needed to diagnose it accurately. We report of BCVI associated with a congenital cervical spine malformation after blunt trauma. We recommend inclusion of cervical spine malformations to the current Eastern Association for the Surgery of Trauma screening criteria for BCVI and explain our rationale for the same.

- See, Test & Treat is a pathologist-driven program to provide cervical and breast cancer screening to underserved and underinsured patient populations. This program is largely funded by the CAP Foundation (College of American Pathologists, Northfield, Illinois) and is a collaborative effort among several medical specialties united to address gaps in the current health care system. - To provide an outline for administering a See, Test & Treat program, using an academic medical center as a model for providing care and collating the results of 5 years of data on the See, Test & Treat program's findings. - Sources include data from patients seen at Tufts Medical Center (Boston, Massachusetts) who presented to the See, Test & Treat program and institutional data between 2010 and 2014 detailing the outline of how to organize and operationalize a volunteer cancer-screening program. - During the 5-year course of the program, 203 women were provided free cervical and breast cancer screening. Of the 169 patients who obtained Papanicolaou screening, 36 (21.3%) had abnormal Papanicolaou tests. In addition, 16 of 130 patients (12.3%) who underwent mammography had abnormal findings. - In general, women from ethnic populations have barriers that prevent them from participating in cancer screening. However, the CAP Foundation's See, Test & Treat program is designed to reduce those barriers for these women by providing care that addresses cultural, financial, and practical issues. Although screening programs are helpful in identifying those who need further treatment, obtaining further treatment for these patients continues to be a challenge.

Limited evidence exists to guide clinical decision making regarding cervical disc herniations in professional athletes playing for the National Football League (NFL) in the United States. To describe the presentation and treatment outcomes of cervical disc herniations in NFL athletes with a focus on safety and return to sport. Case series; Level of evidence, 4. The records of a single NFL team and its consulting physicians were reviewed from 2000 to 2011. Only athletes with magnetic resonance imaging (MRI)-proven disc herniation concordant with the reported symptoms were included. A total of 16 athletes met inclusion criteria. Linemen, linebackers, and defensive backs were the most represented positions (13/16 athletes; 81%). The most common presentation was radiculopathy after a single traumatic event (9/16 athletes; 56%). Three players had transient paresis. Three players underwent one-level anterior cervical discectomy and fusion. These 3 players had failed nonoperative therapy and had evidence of spinal cord compression with signal change on MRI, but only 1 returned to sport. Three players received epidural steroid injections, which provided transient symptomatic relief. Five players were treated nonoperatively and did not return to sport. Two of these 5 athletes had cord compression with signal change and retired rather than undergo surgery. The other 3 were cleared but were released by the team. Eight players were treated nonoperatively and returned to sport. Three of these 8 athletes had evidence of disc material abutting the cord without cord signal change but had a normal examination finding and returned to sport after resolution of their symptoms and repeat MRI that demonstrated no cord compression. Five of the 8 players had evidence of root compression and were treated symptomatically. There were no subsequent traumatic spinal cord injuries at a minimum of 1-year follow-up. Data regarding the treatment of this unique population are limited but suggest that NFL athletes can safely return to sport after the treatment of cervical disc herniations. In the treatment algorithm for this study, cord compression with signal change in the cord on MRI was a consistent operative indication. Discs abutting the cord can be treated nonoperatively but do not allow for return to sport until symptoms have improved and repeat imaging demonstrates no cord compression. Isolated nerve root compression has a more favorable prognosis. It can be treated symptomatically and return to sport allowed when symptoms permit.

Cervical radiculopathy is a common disease that affects millions of people. Patients usually are managed by conservative therapy and surgical treatments. To compare the clinical outcomes between cervical disc arthroplasty (CDA) and conservative management for patients with single level cervical radiculopathy at C5/6. Seventy-two patients with cervical radiculopathy that only affect C5/6 joints were included and thirty-two of them received CDA surgery, and forty patients were treated with conservative management. All the patients were followed up around 4 years. Cervical curvature, cervical range of motion (CROM), horizontal displacement of cervical spine, and intervertebral gap were measured by radiological examination. All the patients have comparable disease severity based on pre-surgical radiological assessments. At the 4-year follow-up examination, patients with CDA surgery had less CROM at C5/6 level, while greater CROM at C4/5 level, than control group. Similarly, the horizontal displacement in CDA group decreased at C5/6 vertebrae, and increased at C4/5 level at the 4-year follow-up examination. The intervertebral gaps of patients in CDA group were larger than control group at one-year and last follow-up examination. CDA surgery stabilized C5/6 vertebrae and increased the CROM and horizontal displacement of upper adjacent C4/5 vertebrae. Copyright © 2018. Published by Elsevier Ltd.

Chemodenervation with botulinum neurotoxin (BoNT) is recommended as first-line treatment for the management of cervical dystonia. The choice of BoNT for treatment is subject to the consideration of several factors, including cost. To compare the costs incurred by patients and payers for onabotulinumtoxinA (ONA) or abobotulinumtoxinA (ABO) for the treatment of cervical dystonia. We conducted a retrospective, noninterventional closed cohort study of cervical dystonia patients within a single U.S. private neurological practice. Patient and payer incurred costs from medical billing records for patients satisfying inclusion and exclusion criteria treated from November 1, 2009, through January 1, 2013, were de-identified and included in the analysis. Forty-seven patients initially treated with at least 3 consecutive cycles of ONA, followed by at least 3 consecutive cycles of ABO were included, representing 282 injection cycles available for analysis. Patients were required to have had a positive response to treatment with both agents and no concomitant treatment with BoNT for any other condition during the analysis period. The analysis compared the primary endpoint of median overall payer and patient incurred costs reimbursed to the clinic under each treatment regimen. For the purposes of this cost analysis, comparable clinical outcomes on both therapies was assumed.   Switching from ONA to ABO resulted in an overall incurred reimbursement cost savings for payers and patients. Median costs per injection cycle for ONA were $1,925 ($0-$2,814) compared with $1,214 ($229-$2,899; P  less than  0.0001) for ABO, representing an approximate 37% reduction in incurred reimbursement costs inclusive of toxin and procedure. Overall toxin reimbursement costs, patient out-of-pocket toxin costs, and the cost of unavoidable waste were also lower when patients were treated with ABO.  For patients treated for cervical dystonia, switching from ONA to ABO resulted in payer and patient reimbursement cost reductions in a single U.S. private practice with outcomes assumed to be similar.

Purpose: ERCC1 (excision repair cross-complementation group 1) expression has been shown to be a molecular marker of cisplatin resistance in many tumor sites, but has not been well studied in cervical cancer patients. The purpose of this study was to measure tumoral ERCC1 in patients with locally advanced cervical cancer treated with chemoradiation therapy (CRT) in a large multicenter cohort, and to correlate expression with clinical outcome parameters. Methods and Materials: A total of 264 patients with locally advanced cervical cancer, treated with curative-intent radical CRT from 3 major Canadian cancer centers were evaluated. Pretreatment formalin-fixed, paraffin-embedded tumor specimens weremore » retrieved, and tissue microarrays were constructed. Tumoral ERCC1 (FL297 antibody) was measured using AQUA (R) technology. Statistical analysis was performed to determine the significance of clinical factors and ERCC1 status with progression-free survival (PFS) and overall survival (OS) at 5 years. Results: The majority of patients had International Federation of Gynecology and Obstetrics (FIGO) stage II disease (n=119, 45%); median tumor size was 5 cm. OS was associated with tumor size (HR 1.16, P=.018), pretreatment hemoglobin status (HR 2.33, P=.00027), and FIGO stage. In addition, tumoral ERCC1 status (nuclear to cytoplasmic ratio) was associated with PFS (HR 2.33 [1.05-5.18], P=.038) and OS (HR 3.13 [1.27-7.71], P=.013). ERCC1 status was not significant on multivariate analysis when the model was adjusted for the clinical factors: for PFS (HR 1.49 [0.61-3.6], P=.38); for OS (HR 2.42 [0.94-6.24] P=.067). Conclusions: In this large multicenter cohort of locally advanced cervical cancer patients treated with radical CRT, stage, tumor size, and pretreatment hemoglobin status were significantly associated with PFS and OS. ERCC1 status appears to have prognostic impact on univariate analysis in these patients, but was not independently associated with outcome on multivariate analysis.« less

The main purpose of this study was to evaluate propofol and its combined effect with cisplatin on apoptosis of cervical cancer cells and molecular mechanisms of this phenomenon. The effects of propofol and cisplatin on cell viability and apoptosis were detected by cell counting kit-8 (CCK-8) assay, colony formation assay and flow cytometry assay. Besides, protein expression of EGFR/JAK2/STAT3 pathway was determined by western blot. STAT3 was over-expressed in cervical cancer cells by STAT3 cDNA. Expression of EGFR and STAT3 protein of human tissues was evaluated by immunohistochemistry (IHC) assay. In this study, we found that not only propofol alone could inhibit cervical cancer cells viability but also could increase the inhibitory effect of cisplatin on cervical cancer cells growth. Meanwhile, propofol sensitized cervical cancer cells to cisplatin-induced apoptosis but not affected normal cervical cells. In genetic level, propofol could enhance the anti-tumor effect of cisplatin through EGFR/JAK2/STAT3 pathway. Further studies indicated that overexpression of EGFR and STAT3 is related to poor prognoses in cervical cancer patients, which contributed to confirm the clinical role of combined application of propofol and cisplatin. Propofol enhances the cisplatin-induced cell apoptosis cervical cancer cells via EGFR/JAK2/STAT3 pathway and may be developed as a potential therapeutic agent to treat cervical cancer.

Cervical cancer is one of the leading causes of cancer death in women. Human papillomaviruses (HPVs) are the major cause in almost 99.7% of cervical cancer. E6 oncoprotein of HPV and E6-associated protein (E6AP) are critical in causing p53 degradation and malignancy. Understanding the E6AP regulation is critical to develop treating strategy for cervical cancer patients. The COP9 signalosome subunit 6 (CSN6) is involved in ubiquitin-mediated protein degradation. We found that both CSN6 and E6AP are overexpressed in cervical cancer. We characterized that CSN6 associated with E6AP and stabilized E6AP expression by reducing E6AP poly-ubiquitination, thereby regulating p53 activity in cell proliferation and apoptosis. Mechanistic studies revealed that CSN6-E6AP axis can be regulated by EGF/Akt signaling. Furthermore, inhibition of CSN6-E6AP axis hinders cervical cancer growth in mice. Taken together, our results indicate that CSN6 is a positive regulator of E6AP and is important for cervical cancer development.

OBJECTIVES: The aim of this study was to review the literature on cervical spine fractures. METHODS: The literature on the diagnosis, classification, and treatment of lower and upper cervical fractures and dislocations was reviewed. RESULTS: Fractures of the cervical spine may be present in polytraumatized patients and should be suspected in patients complaining of neck pain. These fractures are more common in men approximately 30 years of age and are most often caused by automobile accidents. The cervical spine is divided into the upper cervical spine (occiput-C2) and the lower cervical spine (C3-C7), according to anatomical differences. Fractures in the upper cervical spine include fractures of the occipital condyle and the atlas, atlanto-axial dislocations, fractures of the odontoid process, and hangman's fractures in the C2 segment. These fractures are characterized based on specific classifications. In the lower cervical spine, fractures follow the same pattern as in other segments of the spine; currently, the most widely used classification is the SLIC (Subaxial Injury Classification), which predicts the prognosis of an injury based on morphology, the integrity of the disc-ligamentous complex, and the patient's neurological status. It is important to correctly classify the fracture to ensure appropriate treatment. Nerve or spinal cord injuries, pseudarthrosis or malunion, and postoperative infection are the main complications of cervical spine fractures. CONCLUSIONS: Fractures of the cervical spine are potentially serious and devastating if not properly treated. Achieving the correct diagnosis and classification of a lesion is the first step toward identifying the most appropriate treatment, which can be either surgical or conservative. PMID:24270959

Prospective randomized study. To compare the clinical outcome after Discover arthroplasty versus anterior cervical discectomy and fusion (ACDF) in patients treated for symptomatic single-level cervical disk disease. ACDF is still the gold standard for surgical treatment of cervical spine degenerative disk disease. However, results of many studies suggest that it may cause degenerative changes at levels immediately above and below the fusion, known as adjacent segment degenerative disease. Cervical arthroplasty has recently been introduced as an alternative to standard procedure of ACDF. It showed decreased surgical morbidity, decreased complications from postoperative immobilization, and an earlier return to previous level of function. A total of 105 consecutive patients with single-level cervical disk disease, producing radiculopathy and/or myelopathy were randomly divided into groups to undergo ACDF or Discover arthroplasty. All patients were evaluated with preoperative and postoperative serial radiographic studies and clinically, using Neck Disability Index, Visual Analog Scale and neurological status at 3, 6, 12, and 24 months. The results of our study indicate that cervical arthroplasty using Discover Artificial Cervical Disc provides favorable clinical and radiologic outcomes in a follow-up period of 24 months. There has been significant improvement in clinical parameters, Visual Analog Scale and Neck Disability Index, at 3, 6, 12, and 24 months in arthroplasty group comparing to control group. The Discover artificial cervical disc replacement offers favorable outcome compared with ACDF for a single-level cervical disk disease at short-term and long-term follow-up.

Induction of cervical neoplasia in the mouse cervix by herpes simplex virus types 1 (HSV-1) and 2 (HSV-2) has been reported. The present study was done to determine if transfection with DNA of HSV-2 can induce carcinogenesis in this animal model. Genomic HSV-2 DNA was isolated from infected HEp-2 cells and separated from host cell DNA by cesium chloride density gradient centrifugation. The DNA was applied to mouse cervix for periods of 80-100 weeks. Experimental controls were treated with uninfected genomic HEp-2 cell DNA or with calf thymus DNA. Vaginal cytological preparations from all animals were examined monthly to detect epithelial abnormalities. Animals were sacrificed and histopathology studies were done when cellular changes indicative of premalignant or malignant lesions were seen on vaginal smears. Cytologic and histologic materials were coded and evaluated without knowledge of whether they were from animals treated with virus or control DNA. Premalignant and malignant cervical lesions similar to those that occur in women were detected in 61% of the histologic specimens obtained from animals exposed to HSV-2 DNA. The yield of invasive cancers was 21% in animals treated with HSV-2 DNA. No cancers were detected in mice treated with either HEp-2 or calf thymus DNA. Dysplasia was detected in only one of these control animals.

Background The aim of this study was to analyze the clinical features and to evaluate the efficacy of anterior partial corpectomy and titanium mesh fusion and internal fixation of old fracture dislocation of the lower cervical spine. Material/Methods We retrospectively analyzed the clinical data of 52 patients with old lower cervical fracture and dislocation treated with anterior partial corpectomy and titanium mesh fusion fixation between January 2008 and December 2013, with a mean follow-up period of 4.1 years. There were 35 males and 17 females. Patient radiological data and clinical parameters were recorded and compared before and after the operations. Results The average follow-up was 4.1 years. Intervertebral height and physiological curvature were well-reconstructed for all cases. No loosening or rupturing of titanium plate or screw occurred. The neurological function of the patients with incomplete spinal cord injury was significantly improved, and the function of the nerve roots at the injury level was also improved in patients with complete spinal cord injury. Bone fusion was completed within 6 months to 1 year after surgery. Conclusions Completed decompression, sequence and physiological curvature of the cervical vertebra, immediate and long-term anterior cervical column support, and nerve function restoration can be achieved by using anterior partial corpectomy and titanium mesh fusion and internal fixation to treat old fracture dislocation of the lower cervical spine. For cases with locked facet joints or posterior structures invading the vertebral canal, the combined anterior and posterior approaches should be performed, when necessary, to achieve better results.

Objective To characterize population-level surgical treatment patterns for cervical carcinoma in situ (CIS) reported to the Michigan Cancer Surveillance Program (MCSP), and to inform data collection strategies. Methods All cases of cervical carcinoma in situ (CIS) (including cervical intraepithelial neoplasia grade 3 and adenocarcinoma in situ [AIS]) reported to the MCSP during 1998–2003 were identified. First course of treatment (ablative procedure, cone biopsy, loop electrosurgical excisional procedure [LEEP], hysterectomy, unspecified surgical treatment, no surgical treatment, unknown if surgically treated) was described by histology, race, and age at diagnosis. Results Of 17,022 cases of cervical CIS, 82.8% were squamous CIS, 3% AIS/adenosquamous CIS, and 14.2% unspecified/other CIS. Over half (54.7%) of cases were diagnosed in women under age 30. Excisional treatments (LEEP, 32.3% and cone biopsy, 17.3%) were most common, though substantial proportions had no reported treatment (17.8%) or unknown treatment (21.1%). Less common were hysterectomy (7.2%) and ablative procedures (2.6%). LEEP was the most common treatment for squamous cases, while hysterectomy was the most treatment for AIS/adenosquamous CIS cases. Across histologic types, a sizeable proportion of women diagnosed ≤30 years of age underwent excision, either LEEP (20%–38.7%) or cone biopsy (13.7%–44%). Conclusion Despite evidence suggesting it may be safer and equally effective as excision, ablation was rarely used for treating cervical squamous CIS. These population-based data indicate some notable differences in treatment by histology and age at diagnosis, with observed patterns appearing consistent with consensus guidelines in place at the time of study, but favoring more aggressive procedures. Future data collection strategies may need to validate treatment information, including the large proportion of no or unknown treatment. PMID:24002133

Expansive open-door laminoplasty (EOLP) is a useful technique for multiple-level cervical spondylotic myelopathy. The common postoperative complications of EOLP include moderate to severe neck pain, loss of cervical lordosis, decrease of cervical range of motion, and C5 palsy. We modified the surgical technique to lessen these complications. This study is aimed to elucidate the efficacy of modified techniques to lessen the complications of traditional procedures. We collected data from 126 consecutive patients treated at our institution between August 2008 and December 2012. Of these, 66 patients underwent conventional EOLP (CEOLP) and the other 60 patients underwent modified EOLP (MEOLP). The demographic and preoperative data, axial pain visual analog scale scores at 2 weeks and 3 months postoperatively, clinical outcomes evaluated using Nurick score and Japanese Orthopedic Association recovery rate at 12 months postoperatively, and radiographic results assessed using plain films at 3 months and 12 months postoperatively for both groups were compared and analyzed. There were no significant differences regarding the preoperative condition between the CEOLP and MEOLP groups (p > 0.05). The Japanese Orthopedic Association recovery rate of the MEOLP group was 70.3%, comparable to the result of the other group (70.2%). Postoperative axial neck pain, loss of range of motion, and loss of lordosis of cervical curvature decreased significantly in the MEOLP group (p < 0.05). The complications of temporary C5 nerve palsy found in the CEOLP group did not exist in the MEOLP group.

Cervical cancer is a leading cause of death due to cancer among women worldwide. Using transgenic mice to dissect the contributions of the human papillomavirus (HPV) 16 E6 and E7 oncogenes in cervical cancer, E7 was identified previously to be the dominant oncogene. Specifically, when treated with exogenous estrogen for 6 months, E7 transgenic mice developed cancer throughout the reproductive tract, but E6 transgenic mice did not. E6 contributed to carcinogenesis of the reproductive tract, as E6/E7 double transgenic mice treated for 6 months with estrogen developed larger cancers than E7 transgenic mice. In the current study, we investigated whether the E6 oncogene alone could cooperate with estrogen to induce cervical cancer after an extended estrogen treatment period of 9 months. We found that the E6 oncogene synergizes with estrogen to induce cervical cancer after 9 months, indicating that E6 has a weaker but detectable oncogenic potential in the reproductive tract compared with the E7 oncogene. Using transgenic mice that express mutant forms of HPV16 E6, we determined that the interactions of E6 with cellular α-helix and PDZ partners correlate with its ability to induce cervical carcinogenesis. In analyzing the tumors arising in E6 transgenic mice, we learned that E6 induces expression of the E2F-responsive genes, Mcm7 and cyclin E, in the absence of the E7 oncogene. E6 also prevented the expression of p16 in tumors of the reproductive tract through a mechanism mediated by the interaction of E6 with α-helix partners. PMID:17308103

Purpose: There is an important need to improve the effectiveness of radio-chemotherapy (RTCT) for cervical cancer. The CXCL12/CXCR4 pathway can influence RT response by recruiting normal myeloid cells to the tumor microenvironment that in turn can exert radioprotective effects, and may promote metastases. The objective of this study was to explore the efficacy and toxicity of combining RTCT with CXCL12/CXCR4 inhibition in cervical cancer. Experimental Design: CXCR4 expression was measured in 115 patients with cervical cancer. Two primary orthotopic cervical cancer xenografts (OCICx) with different levels of CXCR4 expression were treated with RT (30 Gy: 15 daily fractions) and weekly cisplatin (4 mg/kg), with or without the CXCR4 inhibitor Plerixafor (5 mg/kg/day). The endpoints were tumor growth delay and lymph node metastases. Acute intestinal toxicity was assessed using a crypt cell assay. Results: There was a fivefold variation in CXCR4 mRNA expression in the patient samples, and good correlation between the expression in patients and in the xenografts. The combination of RTCT and Plerixafor produced substantial tumor growth delay and reduced lymph node metastases compared with RTCT alone in both of the xenograft models. There was a trend toward reduced acute intestinal toxicity with the addition of Plerixafor to RTCT. There were no changes in normal organ morphology to suggest increased late toxicity. Conclusions: This study demonstrates that the addition of Plerixafor to standard RTCT improves primary tumor response and reduces metastases in cervical cancer with no increase in toxicity. This combination warrants further investigation in phase I/II clinical trials. Clin Cancer Res; 23(5); 1242-9. ©2016 AACR . ©2016 American Association for Cancer Research.

Retinoids are effective suppressors of the phenotypic development of cancer in many animal systems, whether the process is initiated by chemical, physical or viral carcinogens. Cases of cervical intraepithelial neoplasia are excellent for studying the effectiveness of retinoids as chemopreventive agents because the process can be closely followed by serial colposcopic and pathologic (cytology or biopsy) means and changes in the condition safely monitored. We have previously conducted a phase I study of trans-retinoic acid (Tretinoin) given topically by a collagen sponge and cervical cap. A dose of 0.372% was selected for phase II trial. We have treated 20 patients with topical retinoic acid, and a complete response with total regression of disease was obtained in 50%. Systemic and cervical side effects were mild and vaginal side effects moderate but tolerable. These results provide a clinical basis for a randomized, double-blind phase III study to definitely answer the question of whether retinoic acid is an effective chemopreventive agent for cervical cancer.

Posterior spinal osteosynthesis for cervical fracture/dislocation using a flexible multistrand cable system: technical note.

PubMed

Huhn, S L; Wolf, A L; Ecklund, J

1991-12-01

Cervical instability secondary to fracture/dislocation or traumatic subluxation involving the posterior elements may be treated by a variety of fusion techniques. The rigidity of the stainless steel wires used in posterior cervical fusions often leads to difficulty with insertion, adequate tension, and conformation of the graft construct. This report describes a technique of posterior cervical fusion employing a wire system using flexible stainless steel cables. The wire consists of a flexible, 49-strand, stainless steel cable connected on one end to a short, malleable, blunt leader with the opposite end connected to a small islet. The cable may be used in occipitocervical, atlantoaxial, facet-to-spinous process, and interspinous fusion techniques. The cable loop is secured by using a tension/crimper device that sets the desired tension in the cable. In addition to superior biomechanical strength, the flexibility of the cable allows greater ease of insertion and tension adjustment. In terms of direct operative instrumentation in posterior cervical arthrodesis, involving both the upper and lower cervical spine, the cable system appears to be a safe and efficient alternative to monofilament wires.

Breast and cervical cancers are the commonest cancers diagnosed in women living in low-income and middle-income countries (LMICs), where opportunities for prevention, early detection, or both, are few. Yet several cost-effective interventions could be used to reduce the burden of these two cancers in resource-limited environments. Population- wide vaccination against human papillomavirus (HPV) linked to cervical screening, at least once, for adult women has the potential to reduce the incidence of cervical cancer substantially. Strategies such as visual inspection with acetic acid and testing for oncogenic HPV types could make prevention of cervical cancer programmatically feasible. These two cancers need not be viewed as inevitably fatal, and can be cured, particularly if detected and treated at an early stage. Investing in the health of girls and women is an investment in the development of nations and their futures. Here we explore ways to lessen the divide between LMICs and high-income countries for breast and cervical cancers. Copyright © 2017 Elsevier Ltd. All rights reserved.

A case report on observing the recovery of sensory-motor function after cervical spinal cord transection. Laminectomy and transection of cervical spinal cord (C5) was performed on a male beagle weighing 3.5 kg. After applying polyethylene glycol (PEG) on the severed part, reconstruction of cervical spinal cord was confirmed by the restoration of sensorimotor function. Tetraplegia was observed immediately after operation, however, the dog showed stable respiration and survival without any complication. The dog showed fast recovery after 1 week, and recovered approximately 90% of normal sensorimotor function 3 weeks after the operation, although urinary disorder was still present. All recovery stages were recorded by video camera twice a week for behavioral analysis. While current belief holds that functional recovery is impossible after a section greater than 50% at C5-6 in the canine model, this case study shows the possibility of cervical spinal cord reconstruction after near-total transection. Furthermore, this case study also confirms that PEG can truly expedite the recovery of sensorimotor function after cervical spinal cord sections in dogs.

To evaluate the effect of cervical headgear and lower utility arch in growing skeletal Class II division 1 patients. The patients were divided into 3 groups, the first group was treated with cervical headgear alone (n=20), the second group was treated with cervical headgear and lower utility arch (n=20), and the third group was a control group without treatment (n=20). Cephalometric radiographs were taken and analyzed with SPSS15.0 software package. Student's t test was used to determine if there was significant difference among the 3 groups. Anterior facial height and ramus height displayed significantly increase in the treatment groups than those in the control group; the lower utility arch produced intrusion and lingual tipping of the mandibular incisors and distal tipping without extrusion of the mandibular molars; compared with the control group, maxillary molar total extrusion produced by cervical headgear treatment was not more than 1mm at average. The treatment groups show significant reduction in maxillary protrusion; significant increase in the anterior descent of the PP and ramus height, as a result, mandibular plane orientation is relatively unchanged. The treatment groups have maxillary molar extrusion less than 1mm, which can be considered clinically not significant. The lower utility arch produces mandibular incisor intrusion and lingual tipping, the mandibular molars tip distally without extrusion, the lower utility arch does not influence the mandibular rotation.

In a retrospective review of the cases of thirteen skeletally immature children and adolescents (four to eighteen years old) with instability of the upper part of the cervical spine (occiput to fifth cervical vertebra), we determined the efficacy of posterior arthrodesis and halo-cast immobilization in the management of this condition. The patients were divided into two groups: those with congenital vertebral anomalies alone (fusion or structural defects, or both) and those with cervical anomalies and systemic disorders (dwarfism, juvenile rheumatoid arthritis, Down syndrome, and cerebral palsy). Two patterns of instability were found: instabilities at intervertebral joints adjacent to vertebral fusions, and instabilities located in vertebral defects. For all patients treatment included a posterior arthrodesis with external immobilization by a halo cast, and in two patients internal fixation with wire was also used. Solid arthrodesis was obtained in the twelve patients who were treated with autogenous grafts (iliac cancellous bone in eleven and rib bone in one), and a non-union developed in a child who was treated with bank-bone rib segments. Posterior cervical arthrodesis with wire fixation carries some risk of neural injury and often is not applicable in children with anomalous vertebrae. Spine fusion using delicate exposure, decortication using an air-drill, and placement of autogenous cancellous iliac grafts with external immobilization by a halo cast minimizes the risk of neural damage and is a reliable way to obtain a solid arthrodesis.

Spinal cord injury without radiographic abnormalities (SCIWORA) is thought to represent mostly a pediatric entity and its incidence in adults is rather underreported. Some authors have also proposed the term spinal cord injury without radiologic evidence of trauma, as more precisely describing the condition of adult SCIWORA in the setting of cervical spondylosis. The purpose of the present study was to evaluate adult patients with cervical spine injuries and radiological-clinical examination discrepancy, and to discuss their characteristics and current management. During a 16-year period, 166 patients with a cervical spine injury were admitted in our institution (Level I trauma center). Upper cervical spine injuries (occiput to C2, 54 patients) were treated mainly by a Halo vest, whereas lower cervical spine injuries (C3-T1, 112 patients) were treated surgically either with an anterior, or posterior procedure, or both. Seven of these 166 patients (4.2%) had a radiologic-clinical mismatch, i.e., they presented with frank spinal cord injury with no signs of trauma, and were included in the study. Magnetic resonance imaging was available for 6 of 7 patients, showing intramedullary signal changes in 5 of 6 patients with varying degrees of compression from the disc and/or the ligamentum flavum, whereas the remaining patient had only traumatic herniation of the intervertebral disc and ligamentum flavum bulging. Follow-up period was 6.4 years on average (1-10 years). This retrospective chart review provides information on adult patients with cervical spinal cord injuries whose radiographs and computed tomography studies were normal. It furthers reinforces the pathologic background of SCIWORA in an adult population, when evaluated by magnetic resonance imaging. Particularly for patients with cervical spondylosis, special attention should be paid with regard to vascular compromise by predisposing factors such as smoking or vascular disease, since they probably contribute in the development of SCIWORA.

Some patients with fibromyalgia also exhibit the neurological signs of cervical myelopathy. We sought to determine if treatment of cervical myelopathy in patients with fibromyalgia improves the symptoms of fibromyalgia and the patients' quality of life. A non-randomized, prospective, case control study comparing the outcome of surgical (n = 40) versus non-surgical (n = 31) treatment of cervical myelopathy in patients with fibromyalgia was conducted. Outcomes were compared using SF-36, screening test for somatization, HADS, MMPI-2 scale 1 (Hypochondriasis), and self reported severity of symptoms 1 year after treatment. There was no significant difference in initial clinical presentation or demographic characteristics between the patients treated by surgical decompression and those treated by non-surgical means. There was a striking and statistically significant improvement in all symptoms attributed to the fibromyalgia syndrome in the surgical patients but not in the non-surgical patients at 1 year following the treatment of cervical myelopathy (P

Background Human Papillomavirus (HPV) infection is considered a necessary step for the development of cervical cancer and >95% of all cervical cancers have detectable HPV sequences. We have recently demonstrated the efficacy of radioimmunotherapy (RIT) which targeted viral oncoprotein E6 in treatment of experimental cervical cancer We hypothesized that pre-treatment of tumor cells with various agents which cause cell death and/or elevation of E6 levels would increase the accumulation of radiolabeled antibodies to E6 in cervical tumors. Methods HPV-16 positive CasKi cells were treated in vitro with up to 6 Gy of external radiation, or proteasome inhibitor MG-132 or unlabeled anti-E6 antibody C1P5 and cell death was assessed. Biodistribution of 188Rhenium (188Re)-labeled C1P5 antibody was performed in both control and radiation MG-132 treated CasKi tumor-bearing nude mice. Results . 188Re-C1P5 antibody demonstrated tumor specificity and very low uptake and fast clearance from the major organs. The amount of tumor uptake was enhanced by MG-132 but was unaffected by pre-treatment with radiation. In addition, in vitro studies demonstrated an unanticipated effect of unlabeled antibody on the amount of cell death, a finding that was suggested by our previous in vivo studies in CasKi tumor model. Conclusion We demonstrated that pre-treatment of cervical tumors with proteasome inhibitor MG-132 and with unlabeled antibody to E6 can serve as a means to generate non-viable cancer cells and to elevate the levels of target oncoproteins in the cells for increasing the accumulation of targeted radiolabeled antibodies in tumors. These results favor further development of RIT of cervical cancers targeting viral antigens. PMID:20127955

To provide retrospective, descriptive information on patients with cervical necrotizing fasciitis treated at a single center during the years 1998-2014, and to evaluate the outcome of a newly introduced treatment strategy. Retrospective analysis of clinical data obtained from medical records. Mortality, pre-morbidity, severity of illness, primary site of infection, type of bacteria, time parameters. The observed 3-month mortality was 6/59 (10 %). The most common initial foci of the infection were pharyngeal, dental or hypopharyngeal. The most common pathogen was Streptococcus milleri bacteria within the Streptococcus anginosus group (66 % of the cases). Using a combined treatment with early surgical debridement combined with hyperbaric oxygen treatment, it is possible to reduce the mortality rate among patients suffering from cervical necrotizing fasciitis, compared to the expected mortality rate and to previous historical reports. Data indicated that early onset of hyperbaric oxygen treatment may have a positive impact on survival rate, but no identifiable factor was found to prognosticate outcome.

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

In this retrospective study, we compared the cephalometric effects, the dental-arch changes, and the efficiency of Class II treatment with the pendulum appliance, cervical headgear, or extraction of 2 maxillary premolars, all associated with fixed appliance therapy. The sample of 82 patients with Class II malocclusion was divided into 3 groups: group 1 patients (n = 22; treatment time, 3.8 years) were treated with the pendulum appliance and fixed orthodontic appliances. Group 2 patients (n = 30; treatment time, 3.2 years) were treated with cervical headgear followed by fixed appliances; group 3 patients (n = 30; treatment time, 2.1 years) were treated with 2 maxillary premolar extractions and fixed appliances. The average starting ages of the groups ranged from 13.2 to 13.8 years. Data were obtained from serial cephalometric measurements and dental casts. The dental casts were analyzed with the treatment priority index. The treatment efficiency index was also used. The 3 treatment protocols produced similar cephalometric effects, especially skeletally. Comparisons among the 2 distalizing appliances (pendulum and cervical headgear) and extraction of 2 maxillary premolars for Class II treatment showed changes primarily in the maxillary dentoalveolar component and dental relationships. The facial profile was similar after treatment, except for slightly more retrusion of the upper lip in the extraction patients. The treatment priority index demonstrated that occlusal outcomes also were similar among the groups. The treatment efficiency index had higher values for the extraction group. The effects of treatment with the pendulum appliance or cervical headgear and extraction of 2 maxillary premolars associated with fixed appliances were similar from both occlusal and cephalometric standpoints. Class II treatment with extraction of maxillary teeth was more efficient because of the shorter treatment time. Differences in maxillary incisor retraction should be noted, but these differences might have been due to greater maxillary dentoalveolar protrusion in the extraction group before treatment.

Pelvic exenteration can be used to cure women with a central pelvic recurrence or persistence of gynecologic malignancy after initial definitive therapy. Refinements in patient selection, operative techniques, and surgical instrumentation have significantly improved outcomes over the past 60 years, but the procedure is still associated with significant mortality, morbidity, and recovery time. New technologies have made it possible to approach radical gynecologic surgeries in a minimally invasive fashion. We present 2 patients successfully treated with robotic-assisted anterior pelvic exenteration for treatment of persistent or recurrent cervical cancer after definitive radiotherapy.

Postoperative cervical chylous lymphoceles are extremely rare circumscribed collections of lymph which are usually treated by drainage or surgical exploration, but rarely by sclerotherapy. We investigated the efficacy of OK-432 (Picibanil, Chungai Pharmaceutical Co., Tokyo, Japan) sclerotherapy in the treatment of cervical lymphocele after neck dissection. Four patients with postoperative lymphocele who could not be cured by repeated percutaneous needle aspiration and pressure dressing were treated with intralesional injection of 0.1-0.2 mg OK-432 after aspiration of fluid. The aspirated fluid was assessed biochemically and cytologically, and regular palpation and ultrasonography/computed tomography were used to evaluate outcomes and recurrences. Two patients with chyle leak during neck dissection had lymphoceles in the left supraclavicular region 3 weeks later. The other two patients had lymphoceles on the right neck 9 and 12 months, respectively, after neck dissection. All aspirated fluids were chylous in origin without tumor cells. OK-432 sclerotherapy scored all four lesions with no major complications except for fever and local pain for several days. No lymphocele recurrences or metastatic cancers were observed in any patient for >1 year after sclerotherapy. Intralesional injection of OK-432 may be a safe and effective alternative to surgical exploration in the treatment of cervical lymphocele after neck dissection.

Cervical radiculopathy is a common neuro-musculo-skeletal disorder causing pain and disability. Traction is part of the evidence based manual physical therapy management due to its mechanical nature, type of traction and parameters related to its applicability and are still to be explored more through research. Our objective was to determine the Effects of Mechanical versus Manual Traction in Manual Physical Therapy combined with segmental mobilization and exercise therapy in the physical therapy management of Patients with Cervical Radiculopathy. This randomized control trial was conducted at department of physical therapy and rehabilitation, Rathore Hospital Faisalabad, from February to July 2015. Inclusion criteria were both male and female patients with evident symptoms of cervical spine radiculopathy and age ranged between 20-70 years. The exclusion criteria were Patients with history of trauma, neck pain without radiculopathy, aged less than 20 and more than 70. A total of 72 patients with cervical radiculopathy were screened out as per the inclusion criteria, 42 patients were randomly selected and placed into two groups by toss and trial method, and only 36 patients completed the study, while 6 dropped out. The mechanical traction was applied in group A and manual traction in group B along with common intervention of segmental mobilization and exercise therapy in both groups for 6 weeks. The patient's outcomes were assessed by self reported NPRS and NDI at the baseline and after completion of 06 weeks exercise program at 3 days per week. The data was analyzed through SPSS version-21, and paired T test was applied at 95% level significance to determine the statistical deference between two groups. Clinically the group of patients treated with mechanical traction managed pain (mean pre 6.26, mean post 1.43), and disability (mean pre 24.43 and mean post 7.26) more effectively as compared with the group of patients treated with manual traction (Pain mean pre 6.80, mean post 3.85 and disability mean pre 21.92 and post 12.19). Statistically the results of both mechanical and manual traction techniques are equally significant in group A and B for pain and disability (p-value less than 0.05). If patients of cervical radiculopathy treated with mechanical traction, segmental mobilization, and exercise therapy will manage pain and disability more effectively than treated with manual traction, segmental mobilization, and exercise therapy.

Non-thermal plasma has been extensively researched as a new cancer treatment technology. We investigated the selective cytotoxic effects of non-thermal micro-dielectric barrier discharge (micro-DBD) plasma in cervical cancer cells. Two human cervical cancer cell lines (HeLa and SiHa) and one human fibroblast (HFB) cell line were treated with micro-DBD plasma. All cells underwent apoptotic death induced by plasma in a dose-dependent manner. The plasma showed selective inhibition of cell proliferation in cervical cancer cells compared to HFBs. The selective effects of the plasma were also observed between the different cervical cancer cell lines. Plasma treatment significantly inhibited the proliferation of SiHa cells in comparison to HeLa cells. The changes in gene expression were significant in the cervical cancer cells in comparison to HFBs. Among the cancer cells, apoptosis-related genes were significantly enriched in SiHa cells. These changes were consistent with the differential cytotoxic effects observed in different cell lines.

The involvement of the thyroid by tuberculosis (TB) is rare. Hypothyroidism caused by tissue destruction is an extremely rare report. Our aim was to report a patient with primary thyroid TB emphasizing the importance of diagnosis, despite the rarity of the occurrence. Women, 62 years old, showing extensive cervical mass since four months, referring lack of appetite, weight loss, dysphagia and dysphonia. Laboratorial investigation revealed primary hypothyroidism. Cervical ultrasound: expansive lesion in left thyroid lobe, involving adjacent muscle. Computed tomography scan: 13 cm diameter cervical mass with central necrosis. Fine needle biopsy: hemorrhagic material. total thyroidectomy, left radical neck dissection and protective tracheotomy. The pathological examination showed chronic granulomatous inflammatory process with areas of caseous necrosis and lymph node involvement. The thyroid baciloscopy was positive. Pulmonary disease was absent. The patient was treated with antituberculosis drugs. Thyroid TB is not frequent, and should be considered as differential diagnosis of hypothyroidism and anterior cervical mass.

Surgery for failed cervical spine reconstruction.

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.

OBJECTIVE: To determine the factors influencing cervical cancer diagnosis and treatment in countries of East, Central and Southern Africa (ECSA). METHODS: Data were collected from randomly selected primary health care centres, district and provincial hospitals, and tertiary hospitals in each participating country. Health care workers were interviewed, using a questionnaire; the facilities for screening, diagnosing, and treating cervical cancer in each institution were recorded, using a previously designed checklist. FINDINGS: Although 95% of institutions at all health care levels in ECSA countries had the basic infrastructure to carry out cervical cytology screening, only a small percentage of women were actually screened. Lack of policy guidelines, infrequent supply of basic materials, and a lack of suitable qualified staff were the most common reasons reported. CONCLUSIONS: This study demonstrates that there is an urgent need for more investment in the diagnosis and treatment of cervical cancer in ECSA countries. In these, and other countries with low resources, suitable screening programmes should be established. PMID:11242819

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

Cervical medial branch blocks are used to treat patients with chronic neck pain. The aim of this study was to clarify the anatomical aspects of the cervical medial branches to improve the accuracy and safety of radiofrequency denervation. Twenty cervical specimens were harvested from 20 adult cadavers. The anatomical parameters of the C4-C7 cervical medial branches were measured. The 3-dimensional computed tomography reconstruction images of the bone were also analyzed. Based on cadaveric analysis, most of the cervical dorsal rami gave off 1 medial branch; however, the cervical dorsal rami gave off 2 medial branches in 27%, 15%, 2%, and 0% at the vertebral level C4, C5, C6, and C7, respectively. The diameters of the medial branches varied from 1.0 to 1.2 mm, and the average distance from the notch of inferior articular process to the medial branches was about 2 mm. Most of the bifurcation sites were located at the medial side of the posterior tubercle of the transverse process. On the analysis of 3-dimensional computed tomography reconstruction images, cervical medial branches (C4 to C6) passed through the upper 49% to 53% of a line between the tips of 2 consecutive superior articular processes (anterior line). Also, cervical medial branches passed through the upper 28% to 35% of a line between the midpoints of 2 consecutive facet joints (midline). The present anatomical study may help improve accuracy and safety during radiofrequency denervation of the cervical medial branches.

Cervical radiculopathic pain is a very common symptom that may occur with cervical spondylosis. Mechanical allodynia is often associated with cervical radiculopathic pain and is inadequately treated with current therapies. However, the precise mechanisms underlying cervical radiculopathic pain-associated mechanical allodynia have remained elusive. Compelling evidence from animal models suggests a role of large-diameter dorsal root ganglion neurons and plasticity of spinal circuitry attached with Aβ fibers in mediating neuropathic pain. Whether cervical radiculopathic pain condition induces plastic changes of large-diameter dorsal root ganglion neurons and what mechanisms underlie these changes are yet to be known. With combination of patch-clamp recording, immunohistochemical staining, as well as behavioral surveys, we demonstrated that upon chronic compression of C7/8 dorsal root ganglions, large-diameter cervical dorsal root ganglion neurons exhibited frequent spontaneous firing together with hyperexcitability. Quantitative analysis of hyperpolarization-activated cation current ( I h ) revealed that I h was greatly upregulated in large dorsal root ganglion neurons from cervical radiculopathic pain rats. This increased I h was supported by the enhanced expression of hyperpolarization-activated, cyclic nucleotide-modulated channels subunit 3 in large dorsal root ganglion neurons. Blockade of I h with selective antagonist, ZD7288 was able to eliminate the mechanical allodynia associated with cervical radiculopathic pain. This study sheds new light on the functional plasticity of a specific subset of large-diameter dorsal root ganglion neurons and reveals a novel mechanism that could underlie the mechanical allodynia associated with cervical radiculopathy.

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

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.

To analyze the clinical manifestations of three cases of cervical necrotizing fasciitis caused by klebsiella pneumoniae and to analyze the published articles concerning the relationship between invasive klebsiella syndrome and necrotizing fasciitis in Chinese Mainland. We have retrospectively analyzed three cases of cervical necrotizing fasciitis caused by klebsiella pneumoniae treated in our department between 2003 and 2012. We also reviewed the Chinese-language scientific literature included in the WanFang data by searching with the following key words: necrotizing fasciitis, klebsiella pneumoniae and liver abscess. These patients recovered uneventfully without obvious complications or disseminated infection foci. Sporadic cases of invasive klebsiella syndrome were reported without necrotizing fasciitis involvement in Chinese Mainland. Cervical necrotizing fasciitis caused by klebsiella pneumoniae may give rise to disseminated infection but there has been no such case report in Chinese Mainland.

We analyzed cervical cancer incidence and mortality data in American Indian and Alaska Native (AI/AN) women compared with women of other races. We improved identification of AI/AN race, cervical cancer incidence, and mortality data using Indian Health Service (IHS) patient records; our analyses focused on residents of IHS Contract Health Service Delivery Area (CHSDA) counties. Age-adjusted incidence and death rates were calculated for AI/AN and White women from 1999 to 2009. AI/AN women in CHSDA counties had a death rate from cervical cancer of 4.2, which was nearly twice the rate in White women (2.0; rate ratio [RR] = 2.11). AI/AN women also had higher incidence rates of cervical cancer compared with White women (11.0 vs 7.1; RR = 1.55) and were more often diagnosed with later-stage disease (RR = 1.84 for regional stage and RR = 1.74 for distant stage). Death rates decreased for AI/AN women from 1990 to 1993 (-25.8%/year) and remained stable thereafter. Although rates decreased over time, AI/AN women had disproportionately higher cervical cancer incidence and mortality. The persistently higher rates among AI/AN women compared with White women require continued improvements in identifying and treating cervical cancer and precancerous lesions.

These studies represent further investigations that have been done utilizing the fluorescence from pyridinoline, one of the major crosslinks of type I and III collagen, to evaluate cervical connective tissue changes during various female reproductive periods. Based on our previous studies, a prototype instrument has been constructed. The instrument was specifically designed for the purpose of vaginal examination of cervical connective tissue by measuring light induced fluorescence directly from the surface of the external os of the cervix. The studies were carried out on nonpregnant rats, rats during gestation at different periods, rats at different times during postpartum, and rats during preterm birth after being treated with antiprogesterone drugs. A study has also been done on humans during pregnancy and postpartum. The results parallel previous investigations that have used various invasive methods to analyze cervical extensibility, cervical collagen content and collagenase. In consideration of the important role of the collagen fibers and their turnover in the process of cervical function during pregnancy (softening or ripening at term), this method could be a useful tool for evaluating treatment strategies of the cervix. Moreover, the instrument could serve as a device for the non-invasive estimation of cervical status in the clinic and the diagnosis of the changes in the cervix during the preparation for labor.

The aim of this study was to evaluate the effectiveness and toxicities of three-dimensional conformal radiation therapy (3DCRT), intensity-modulated radiation therapy (IMRT), and volumetric-modulated arc therapy (VMAT) in patients with cervical esophageal cancer. Specifically, we asked whether technological advances conferred an advantage with respect to the clinical curative effect. Seventy-eight patients with cervical esophageal cancer treated with definitive radiotherapy with or without concomitant chemotherapy at our institution between 2007 and 2014 were enrolled in the study: 26 received 3DCRT, 30 were treated with IMRT, and 22 underwent VMAT. Kaplan-Meier analysis and the Cox proportional hazard model were used to analyze overall survival (OS) and failure-free survival (FFS). Treatment-related toxicity was also assessed. For all patients, the 2-year OS and FFS rates were 56.2 and 53.9%, respectively. The 2-year OS for the 3DCRT, IMRT, and VMAT groups was 53.6, 55.6, and 60.6%, respectively (P = 0.965). The corresponding 2-year FFS rates were 49.5, 56.7, and 60.1% (P = 0.998). A univariate analysis of the complete response to treatment showed an advantage of treatment modality with respect to OS (P < 0.001). The development of acute hematologic toxicity was not significantly different among the three groups. The survival rates of patients treated with IMRT and VMAT were comparable to the survival of patients administered 3DCRT, while lower lung mean dose, V20, maximum dose of brachial plexus and spinal cord. Grade 1 radiation pneumonitis occurred significantly less in patients treated with IMRT and VMAT than with 3DCRT (P = 0.011). A complete response was the most important prognostic factor of the patients with cervical esophageal cancer. © 2016 International Society for Diseases of the Esophagus.

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.

Objective: To analyze differences in survival between black and non-black women diagnosed with cervical cancer and treated at the National Cancer Institute in Brazil. Methods: This retrospective cohort study was conducted using medical records of patients who were treated for cervical cancer between 2006 and 2009 at the Brazilian National Cancer Institute - Rio de Janeiro - Brazil. The clinical and epidemiological characteristics of black and non-black patients were compared using the chi-square test. Survival functions over five years were calculated using the Kaplan-Meier estimator and compared using the log-rank test. Associations between race and mortality risk were analyzed using the Cox proportional hazards model. P-values <0.05 were considered statistically significant. Results: The study included 1,482 women, of whom 188 (12.7%) were black, 1,209 (81.6%) were non-black and 85 (5.7%) were of unspecified race. The age at diagnosis of the patients ranged from 19 to 84 years (mean 50.1 years; SD±13.2). Hemoglobin <12 g/dL at the time of diagnosis (p=0.008) and absence of surgery as primary treatment (p = 0.005) were more frequent among black women. Cox analysis adjusted for these two factors showed no statistically significant difference in the mortality risk associated with cervical cancer among black and non-black women (HR=1.1 95% CI 0.9-1.5; p=0.27). Conclusion: After adjusting for hemoglobin levels and surgery, race alone was not shown to be a prognostic factor for patients with cervical cancer. Creative Commons Attribution License

We report a rare case of anterolateral meningioma of the foramen magnum (FMM) and high cervical spine presenting both intradural and extradural growth in a 7.5-year-old boy. We also performed a review of the relevant peer-reviewed literature. The patient presented with progressive tetraparesis and gait instability. Neuroimaging revealed an anterolateral tumor of the foramen magnum, C1 and C2 cervical spine level. The patient was treated in two stages: During the first operation, the extradural part was resected while the intradural part was removed in a second operation. Following the second operation, the patient showed almost complete neurological recovery as a result of cervical spinal cord and brainstem decompression but was complicated with cerebrospinal fluid leakage and infection by Acinetobacter. He sustained two further operations for dural sealing and external ventricular drainage and was treated with intraventricular administration of antibiotics. Histopathology of the tumor confirmed a meningotheliomatous meningioma. At the 6-month post-op follow-up examination, the patient exhibited complete neurological recovery and no radiological tumor recurrence. To the authors' best knowledge, we report the third case of sporadic pediatric meningioma of the foramen magnum and high cervical compartments with an extradural growth. Accurate pre-operative estimation of possible extradural growth is crucial towards surgical planning and sufficient treatment. Treatment of choice is total resection in a single operating session to avoid re-operations and increased risk of complications. If not possible, a re-operation should always attempt to secure the desired result.

Thyroid imaging is indicated to evaluate congenital hypothyroidism during newborn screening or in cases of a palpable thyroid mass in children and adolescents. This pictorial essay reviews the ultrasonography (US) of thyroid diseases in children and adolescents, including normal thyroid gland development, imaging features of congenital thyroid disorders (dysgenesis, [aplasia, ectopy, hypoplasia], dyshormonogenesis, transient hypothyroidism, thyroglossal duct cyst), diffuse thyroid disease (Grave's disease, Hashimoto's thyroiditis, and suppurative thyroiditis), and thyroid nodules. The primary imaging modalities for evaluating thyroid diseases are US and radionuclide scintigraphy. Additionally, US can be used to guide aspiration of detected nodules. PMID:25741204

Bilateral vertebral artery lesion after dislocating cervical spine trauma. A case report.

This case report illustrates the problems associated with diagnosis and management of vertebral artery injuries resulting from dislocating cervical spine trauma. Treatment involved the principles of anterior stabilization of dislocating cervical spine fracture as well as the diagnostic procedures and therapeutic modalities appropriate for vertebral artery lesions. Because vertebral artery injuries with cervical spine trauma are rarely symptomatic, they can easily be overlooked. Bilateral or dominant vertebral artery occlusion, however, may cause fatal ischemic damage to the brain stem and cerebellum. Cervical spine dislocation was stabilized immediately after admission using internal fixation by ventral plate and corticocancellous bone graft. Immediate angiography was performed when brain stem neurologic dysfunction manifested 36 hours after surgery. The patient was treated with anticoagulation, osmotherapy, and controlled hypertension. A fatal outcome resulted in this case of dominant left vertebral artery occlusion. Necropsy even revealed bilateral vertebral artery damage at the level of the osseous lesion. The possibility of the complication of a vertebral artery lesion should be kept in mind when examining patients with cervical spine trauma, especially in patients with fracture-dislocation. Immediate identification by vertebral angiography, magnetic resonance imaging, or thin-slice computed tomography scan is necessary for optimal management of this injury.

Recently, there are tendency to use natural products such as Ziziphus Jujube (Jujube) as therapeutic agents for cancer. Understanding the molecular mechanisms of anti-cancer effects of Jujube may improve the current therapeutic strategies against cervical cancer. Our MTT data showed a significant dose- and time-dependent inhibition of OV-2008 cell proliferation following Jujube administration. Moreover, qRT-PCR analyses significantly revealed the suppression of cyclin D1 and the enhancement of P53, P21 and P27 expression in treated cells. These results suggest that the herb exerts a cytotoxic effect on cervical cancer cells through alternation of the expression of the genes that are involved in regulation of cell cycle.

Cervical spondylotic radiculo-myelopathy in patients with athetoid-dystonic cerebral palsy: clinical evaluation and surgical treatment.

PubMed Central

1984-01-01

The acute onset of symptoms of severe cervical radiculo-myelopathy in four patients with athetoid-dystonic cerebral palsy is reported. Neurological and radiological examination showed that the spondylotic changes of the cervical spine were responsible for new neurological deficits leading to the patients being bedridden. Dystonic-athetoid neck movements may cause excessive axial neck rotation as well as flexion and extension movements of the spine. These repetitive exaggerated movements may result in early degenerative changes of the vertebrae which may enhance the radiculo-myelopathy. The four patients were treated with an anterior discectomy with interbody fusion. They were bedridden pre-operatively but all have since been able to walk with or without a cane. It is concluded that early anterior decompression with interbody fusion is a treatment of choice for cervical spondylotic radiculo-myelopathy in association with athetoid cerebral palsy.

Hirayama disease is an initially progressive disease caused by cervical neck flexion compressing the anterior horns of the lower cervical spinal cord. It is primarily seen in young males of Indian or Asian descent. With increasing dispersion of these populations this condition is increasingly being encountered internationally. This grand round reviews this rare but increasingly recognized condition. We present a classic case of a young Indian male with progressive hand and forearm weakness. We discuss the typical clinical presentation, appropriate investigations and management of this condition. Our patient presented with oblique amyotrophy and underwent a diagnostic flexion MRI scan which revealed anterior translation of the posterior dura with compression of the anterior horns of the lower cervical cord. He has been successfully treated in a cervical collar. This case illustrates the typical presentation, diagnostic investigations and treatment of Hirayama syndrome. It is hoped that this review will alert clinicians of this condition and optimize the management of affected individuals.

Introduction This study aims to compare the antioxidant abilities of cervical squamous carcinoma cells and cervical adenocarcinoma cells and to study the related mechanisms. Material and methods Cervical squamous carcinoma and adenocarcinoma cells were treated with H2O2. Cell proliferation was determined with the MTT assay. The reactive oxygen species (ROS) level was detected by the 2’,7’-dichlorofluorescein-diacetate (DCFH-DA) method. The 5,5’-dithiobis-2-nitrobenzoic acid (DTNB) method was performed to measure intracellular concentrations of reduced glutathione (GSH) and oxidized glutathione (GSSG). The nitrite formation method, the molybdate colorimetric method, and the DTNB colorimetric method were used to determine activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx), respectively. Results Compared with untreated control cells, cell proliferation of cervical squamous carcinoma cells and cervical adenocarcinoma cells was significantly inhibited by H2O2 treatment (p < 0.05). Reactive oxygen species levels and GSSG levels were significantly increased (p < 0.01), whereas GSH levels were significantly decreased (p < 0.05 or 0.01) in both cells after H2O2 treatment. Thus the ratio of GSH/GSSG was significantly decreased by H2O2 treatment in both cells (p < 0.01). In addition, H2O2 treatment significantly increased activities of SOD, CAT, and GPx in both cells (p < 0.05 or 0.01). Furthermore, the above-mentioned changes induced by H2O2 treatment were more dramatic in cervical squamous carcinoma cells. Conclusions The antioxidant ability of cervical squamous carcinoma cells is lower than that of cervical adenocarcinoma cells, which may be related to the increased ROS levels in cervical squamous carcinoma cells induced by H2O2 treatments.

To evaluate the causes, treatment and prevention of esophageal fistulas after anterior cervical spine surgery. Between January 2004 and December 2011, 5 of 2348 patients who underwent anterior cervical surgery in our hospital developed esophageal fistulas (three male and two female patients, average age 34 years). Their diagnoses were cervical injuries (three), cervical spondylosis (one) and cervical tuberculosis (one). Their esophageal fistulas were treated by debridement and exploratory surgery, primary suturing of the perforation and/or sternocleidomastoid myoplasty. If conservative treatment failed or esophageal fistula recurred, plate removal was offered. Postoperative treatment included esophageal rest, enteral nutrition, wound drainage, and antibiotics. Methylene blue was used to evaluate results. An esophageal fistula was discovered during anterior cervical surgery in one patient and primary suturing performed. In four patients, fistulas were diagnosed after anterior cervical decompression and fusion. In one of these, only debridement and exploratory surgery were required. In another, a perforation was sutured during debridement and exploratory surgery. In the third, internal fixation was removed because of failure of prolonged conservative treatment. In the fourth, the esophageal fistula recurred repeatedly; he required removal of the hardware and reinforcement with a sternocleidomastoid muscle flap. At 6-48 months follow-up, all patients were in good condition, symptom free, and without cervical instability or infectious spondylitis. Successful management of esophageal fistula after anterior cervical spinal surgery depends on primary closure of the perforation with or without muscle flaps, surgical drainage, esophageal rest and nutritional support, and removal of hardware if necessary. Prevention consists of careful surgery and gentle tissue handling. © 2012 Tianjin Hospital and Wiley Publishing Asia Pty Ltd.

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

Purpose: The management of patients with cervical lymph-node metastases from unknown primary site (UPS) remains a matter of discussion. This study aimed to analyze the results and prognostic factors in a series of patients treated with radiotherapy. Methods and Materials: Data from 113 patients who presented with cervical lymph nodes metastases from UPS treated from 1980 to 2004 were reviewed. Eighty-seven patients (77.0%) were squamous cell carcinoma (SCC). Ninety-one patients were treated with curative and 22 with palliative intent. Fifty-nine of 113 patients (52.2%) received surgery followed by radiotherapy and 54 of 113 (47.8%) received radiotherapy alone. Radiotherapy was deliveredmore » to the neck and pharyngeal mucosa in 67 patients and to the ipsilateral or bilateral neck in 45 patients. Twenty-one patients (18.5%) also received chemotherapy. Results: The 5-year overall survival rates were 40.7% for the entire group and 46.6% for the SCC subgroup. The occurrence of the occult primary was observed in 23 of 113 patients (20.3%), 19 (82.6%) within the head and neck region. At multivariate analysis, treatment with curative intent and extensive irradiation of bilateral neck and pharyngeal mucosa were favorable prognostic factors for the whole series, and treatment with curative intent, extensive irradiation of bilateral neck and pharyngeal mucosa, and absence of extracapsular spread were favorable prognostic factors for the SCC subgroup. Conclusions: Patients with cervical lymph node metastases from UPS have a similar prognosis to those affected by other head and neck malignancies. Curative treatment strategies including neck dissection and extensive irradiation by three-dimensional conformal radiation therapy resulted in significantly better outcomes.« less

Delays in time to treatment initiation (TTI) with definitive radiation therapy (RT) or chemotherapy and RT (CRT) for cervical cancer could lead to poorer outcomes. This study investigates disparities in TTI and the impact of TTI on overall survival (OS). Adult women with non-metastatic cervical squamous cell carcinoma diagnosed between 2004 and 2014, treated with definitive RT or CRT, and reported to the National Cancer Database were included. TTI was defined as days from diagnosis to start of RT or CRT. The impact of TTI on OS in patients treated with concurrent CRT which included brachytherapy was then assessed. Overall, 14,924 patients were included (84.7% CRT, 15.3% RT). TTI was significantly longer for Non-Hispanic Black (NHB) (RR, 1.14; 95% CI, 1.11 to 1.18) and Hispanic women (RR, 1.19; 95% CI, 1.15 to 1.24) compared to Non-Hispanic White (NHW) women. Expected TTI (eTTI) for NHW, NHB, and Hispanic women were 38.1, 45.2, and 49.4days. eTTI rose from 36.2days in 2004 to 44.3days by 2014. Intensity-modulated radiation therapy (IMRT) was associated with increased eTTI of 46.5days versus 40.0days for non-IMRT. Longer TTI was not associated with inferior OS in patients treated with concurrent CRT. Delays in starting RT/CRT for cervical cancer increased from 2004 to 2014. Delays disproportionately affect NHB and Hispanic women. However, increased TTI was not associated with increased mortality for women receiving CRT. Further study of TTI's impact on other endpoints is warranted to determine if TTI represents an important quality indicator. Copyright © 2017 Elsevier Inc. All rights reserved.

To estimate efficacy of a visual triage of human papillomavirus (HPV)-positive women to either immediate cryotherapy or referral if not treatable (eg, invasive cancer, large precancers). We evaluated visual triage in the HPV-positive women aged 25 to 55 years from the 10,000-woman Guanacaste Cohort Study (n = 552). Twelve Peruvian midwives and 5 international gynecologists assessed treatability by cryotherapy using digitized high-resolution cervical images taken at enrollment. The reference standard of treatability was determined by 2 lead gynecologists from the entire 7-year follow-up of the women. Women diagnosed with histologic cervical intraepithelial neoplasia grade 2 or worse or 5-year persistence of carcinogenic HPV infection were defined as needing treatment. Midwives and gynecologists judged 30.8% and 41.2% of women not treatable by cryotherapy, respectively (P < 0.01). Among 149 women needing treatment, midwives and gynecologists correctly identified 57.5% and 63.8% (P = 0.07 for difference) of 71 women judged not treatable by the lead gynecologists and 77.6% and 59.7% (P < 0.01 for difference) of 78 women judged treatable by cryotherapy. The proportion of women judged not treatable by a reviewer varied widely and ranged from 18.6% to 61.1%. Interrater agreement was poor with mean pairwise overall agreement of 71.4% and 66.3% and kappa's of 0.33 and 0.30 for midwives and gynecologists, respectively. In future "screen-and-treat" cervical cancer prevention programs using HPV testing and cryotherapy, practitioners will visually triage HPV-positive women. The suboptimal performance of visual triage suggests that screen-and-treat programs using cryotherapy might be insufficient for treating precancerous lesions. Improved, low-technology triage methods and/or improved safe and low-technology treatment options are needed.

Systemic and local infections and inflammations are known to cause infertility in humans and animals. However, the mechanisms by which infection/inflammation induces infertility are only partially known. The objectives of this study were: (i) to provide models of systemic (acute) and local (sub-acute) inflammation by intra-peritoneal injection or intra-cervical deposition of lipopolysaccharide (LPS) in the rabbit and (ii) to assess their effects on uterine tissues and sperm transport in the genital tract of rabbit does. Intra-peritoneal administration of different doses of LPS induced systemic effects such as fever, anorexia and changes in white blood cells (WBC) count. In our study, LPS inoculation (100μg/kg) produced an inflammation-like status that lasted for about 3 days, with minimal distress for the animals. Intra-peritoneal administration of LPS 60h before artificial insemination induced a rapid increase of IL-1β concentrations. The intra-cervical inoculation of LPS did not show any systemic effects, as confirmed by the lack of changes in body temperature, feed intake and WBC count. Histological examination of uterine tissues showed an endometritis-like inflammation status in LPS-treated does, more severe in those inoculated intra-cervically. The number of spermatozoa recovered from uterine horns and oviducts of intra-cervically treated does was less than that retrieved from intra-peritoneally treated animals and controls. These results suggest (i) that sub-acute or acute inflammation may cause infertility by compromising the uterine environment and/or impairing sperm transport and (ii) that the LPS-induced -infection/inflammation experimental model is useful for studying the mechanisms involved in reproductive dysfunctions in the rabbit.

The aim of this study was to compare the efficacy and safety of anterior cervical discectomy and fusion (ACDF) and cervical arthroplasty for patients with cervical spondylosis. PubMed, Embase, and Cochrane Library were used to search for relevant articles published prior to April 2016 to identify studies comparing ACDF and cervical arthroplasty involving patients with cervical spondylosis. Relative risks (RR) and mean differences (MD) were used to measure the efficacy and safety of ACDF and cervical arthroplasty using the random effects model. The meta-analysis of 17 studies involved 3122 patients diagnosed with cervical spondylosis. Patients undergoing ACDF showed lower overall success rate (RR 0.84; 95 % CI 0.77-0.92; P < 0.001), higher VAS score (MD 0.36; 95 % CI 0.08-0.64; P = 0.011), and shorter mean surgical duration (MD -1.62; 95 % CI -2.80 to -0.44; P = 0.007) when compared with cervical arthroplasty. However, the association between ACDF therapy and the risk of mean blood loss (MD -0.16; 95 % CI -0.34 to 0.02; P = 0.082), mean hospitalization (MD 0.02; 95 % CI -0.31 to 0.36; P = 0.901), patient satisfaction (RR 0.96; 95 % CI 0.92-1.00; P = 0.066), neck disability index (MD 0.20; 95 % CI -0.05 to 0.44; P = 0.113), reoperation (RR 1.25; 95 % CI 0.64-2.41; P = 0.514), or complication (RR 1.17; 95 % CI 0.90-1.52; P = 0.242) was not statistically significant. Patients undergoing ACDF therapy tended to exhibit lower overall success rate, higher VAS score, and decreased mean surgical duration when compared with patients treated with cervical arthroplasty.

Objective Costs associated with HPV-related diseases such as cervical dysplasia, cervical cancer, and genital warts have not been evaluated in Sweden. These costs must be estimated in order to determine the potential savings if these diseases were eradicated and to assess the combined cost-effectiveness of HPV vaccination and cervical cancer screening. The present study aimed to estimate prevention, management, and treatment costs associated with cervical dysplasia, cervical cancer, and genital warts from a societal perspective in Sweden in 2009, 1 year before the quadrivalent HPV vaccination program was implemented. Methods and Materials Data from the Swedish cervical cancer screening program was used to calculate the costs associated with prevention (cytological cervical cancer screening), management (colposcopy and biopsy following inadequate/abnormal cytological results), and treatment of CIN. Swedish official statistics were used to estimate treatment costs associated with cervical cancer. Published epidemiological data were used to estimate the number of incident, recurrent, and persistent cases of genital warts; a clinical expert panel assessed management and treatment procedures. Estimated visits, procedures, and use of medications were used to calculate the annual cost associated with genital warts. Results From a societal perspective, total estimated costs associated with cervical cancer and genital warts in 2009 were €106.6 million, of which €81.4 million (76%) were direct medical costs. Costs associated with prevention, management, and treatment of CIN were €74 million; screening and management costs for women with normal and inadequate cytology alone accounted for 76% of this sum. The treatment costs associated with incident and prevalent cervical cancer and palliative care were €23 million. Estimated costs for incident, recurrent and persistent cases of genital warts were €9.8 million. Conclusion Prevention, management, and treatment costs associated with cervical dysplasia, cervical cancer, and genital warts are substantial. Defining these costs is important for future cost-effectiveness analyses of the quadrivalent HPV vaccination program in Sweden. PMID:26398189

Background Cervical fractures from falls are a potentially lethal injury in older patients. Little is known about their epidemiology and outcomes. Objectives To examine the prevalence of cervical spine fractures after falls among older Americans and show changes in recent years. Further, to compare 12-month outcomes in patients with cervical and hip fracture after falls. Design, Setting, and Participants A retrospective study of Medicare data from 2007–2011 including patients ≥65 with cervical fracture and hip fracture after falls treated at acute care hospitals. Measurements Rates of cervical fracture, 12-month mortality and readmission rates after injury. Results Rates of cervical fracture increased from 4.6/10,000 in 2007 to 5.3/10,000 in 2011, whereas rates of hip fracture decreased from 77.3/10,000 in 2007 to 63.5/10,000 in 2011. Patients with cervical fracture without and with spinal cord injury (SCI) were more likely than patients with hip fracture, respectively, to receive treatment at large hospitals (54.1%, 59.4% vs. 28.1%, p< 0.001), teaching hospitals (40.0%, 49.3% vs. 13.4%, p< 0.001), and regional trauma centers (38.5%, 46.3% vs. 13.0%, p< 0.001). Patients with cervical fracture, particularly those with SCI, had higher risk-adjusted mortality rates at one year than those with hip fracture (24.5%, 41.7% vs. 22.7%, p<0.001). By one year, more than half of patients with cervical and hip fracture died or were readmitted to the hospital (59.5%, 73.4% vs. 59.3%, p<0.001). Conclusion Cervical spine fractures occur in one of every 2,000 Medicare beneficiaries annually and appear to be increasing over time. Patients with cervical fractures had higher mortality than those with hip fractures. Given the increasing prevalence and the poor outcomes of this population, hospitals need to develop processes to improve care for these vulnerable patients. PMID:26456855

This study aimed to figure out three-year clinical outcomes and complications of ACDF with Zero-p in treating multilevel cervical spondylotic myelopathy (MCSM) by comparing with plate fixation. Patients with MCSM caused by degenerative disc herniation only were recruited from April 2010 to December 2010. According to the surgical procedures, the patients were divided into two groups at random, the plate group and Zero-P group. The data was collected before surgery and at three-year follow-up. Clinical parameters, including Japanese orthopedic association (JOA) score, neck disabled index (NDI) were evaluated. Cervical segmental lordosis was calculated and fusion in each level was assessed on lateral radiographs. The Bazaz's criterion and the short Swallowing and Quality of Life (SQOL) questionnaires were used to evaluate the dysphagia incidence and severity respectively. The presence of ALOD was observed and recorded on lateral radiographs. A total of 72 patients (46 men and 26 women) were recruited. The mean age at operation was 52.9±7.9years, ranged from 43 to 69 years. There was no significant difference between two groups preoperatively in age, sex, operative levels, JOA, NDI, cervical lordosis, dysphagia incidence, SQOL and ALOD incidence. JOA, NDI and cervical lordosis improved postoperatively and postoperative SQOL got restitution in both groups. However, no difference was detected. There were 7 patients with ALOD in the plate group after surgeries while there was only 1 patient in Zero-P group. The difference of AOLD incidence between them was significant. Of the 7 patients with ALOD in the plate group, 4 patients developed ALOD in cranial level, 2 in caudal level and 1 in both levels. The patient in Zero-P group developed ALOD in caudal level. Based on the three-year follow-up, we could not conclude that Zero-P was superior to plate fixation in clinical outcomes such as neurological results, cervical lordosis, fusion rate and the incidence and severity of dysphagia in treating MCSM. However, it had the advantage of reducing ALOD incidence which tended to happen in ACDF with plate fixation. Copyright © 2016 Elsevier B.V. All rights reserved.

The rat parvovirus H-1PV has oncolytic and tumour-suppressive properties potentially exploitable in cancer therapy. This possibility is being explored and results are encouraging, but it is necessary to improve the oncotoxicity of the virus. Here we show that this can be achieved by co-treating cancer cells with H-1PV and histone deacetylase inhibitors (HDACIs) such as valproic acid (VPA). We demonstrate that these agents act synergistically to kill a range of human cervical carcinoma and pancreatic carcinoma cell lines by inducing oxidative stress, DNA damage and apoptosis. Strikingly, in rat and mouse xenograft models, H-1PV/VPA co-treatment strongly inhibits tumour growth promoting complete tumour remission in all co-treated animals. At the molecular level, we found acetylation of the parvovirus nonstructural protein NS1 at residues K85 and K257 to modulate NS1-mediated transcription and cytotoxicity, both of which are enhanced by VPA treatment. These results warrant clinical evaluation of H-1PV/VPA co-treatment against cervical and pancreatic ductal carcinomas. PMID:24092664

Cervical cancer is the most common cancer in women, and ranks seventh of all cancers worldwide, with 529000 cases in 2008 and more than 85% cases occur in developing countries. One way to treat this cancer is through the inhibition of HDAC enzymes which play a strategic role in the regulation of gene expression. Suberoyl Anilide Hydroxamic Acid (SAHA) or Vorinostat is a drug which commercially available to treat the cancer, but still has some side effects. This research present in silico SAHA modification in Zinc Binding Group (ZBG) by organoselenium compound to get ligands which less side effect. From molecular docking simulation, and interaction analysis, there are five best ligands, namely CC27, HA27, HB28, IB25, and KA7. These five ligands have better binding affinity than the standards, and also have interaction with Zn2+ cofactor of inhibited HDAC enzymes. This research is expected to produce more potent HDAC inhibitor as novel drug for cervical cancer treatment.

Motility is the feature that allows spermatozoa to actively reach and penetrate the female gamete during fertilization. When this function is altered, and especially decreased, troubles in conceiving may occur. In this study, we demonstrated that treating fertile women with myo-inositol (MI) vaginal suppositories ameliorated their partners' sperm motility and also positively affected their conceiving capacity, without changes in cervical mucus structural and biochemical characteristics. Indeed, by means of the postcoital test on female cervical mucus, a significant improvement especially in progressive sperm motility was recorded after MI suppository use. Concomitantly, after MI treatment, a reduction of immotile spermatozoa percentage was observed. Importantly, MI vaginal supplementation positively correlated with a pregnancy for 5 of the 50 couples enrolled in the study, leading us to speculate that this substance may substantially contribute to create in the cervical mucus an ideal milieu that makes spermatozoa more motile and functionally able to fertilize. Even though the detailed mechanism is still unclear, these results should encourage MI vaginal use for the clinical improvement of male infertility, through their partners.

Cervical cancer is one of the most prevalent malignancies in women worldwide. Therefore, the investigation about the molecular pathogenesis and related therapy targets of cervical cancer is an emergency. The objective of the present study is to investigate the effects of valproic acid (VPA), a histone deacetylase inhibitor, on the angiogenesis of cervical cancer. The effects and mechanisms of VPA on in vitro angiogenesis and vascular endothelial growth factor (VEGF) expression of human cervical cancer HeLa and SiHa cells were investigated. Our present study reveals that 1 mM VPA can significantly inhibit the in vitro angiogenic potential and VEGF expression of human cervical cancer HeLa and SiHa cells. Further, the transcription and protein levels of hypoxia inducible factor-1α (HIF-1α), and not HIF-1β, are significantly inhibited in VPA-treated cervical cancer cells. Over expression of HIF-1α can obviously reverse VPA-induced VEGF down regulation. VPA-treatment decreases the activation of Akt and ERK1/2 in both HeLa and SiHa cells in a time-dependent manner. The inhibitor of Akt (LY 294002) or ERK1/2 (PD98059) can inhibit VEGF alone and cooperatively reinforce the suppression effects of VPA on HIF-1α and VEGF expression. Collectively, our data reveal that the inhibition of PI3K/Akt and ERK1/2 signals are involved in VPA-induced HIF-1α and VEGF suppression of cervical cancer cells.

Radical hysterectomy has been developed as a standard treatment in Stage I and II cervical cancers with and without adjuvant therapy. However, there have been several attempts to standardize the technique of radical hysterectomy required for different tumor extension with variable success. Total mesometrial resection as ontogenetic compartment-based oncologic surgery - developed by open surgery - can be standardized identically for all patients with locally defined tumors. It appears to be promising for patients in terms of radicalness as well as complication rates. Robotic surgery may additionally reduce morbidity compared to open surgery. We describe robotically assisted total mesometrial resection (rTMMR) step by step in cervical cancer and present feasibility data from 26 patients. Patients (n = 26) with the diagnosis of cervical cancer were included. Patients were treated by robotic total mesometrial resection (rTMMR) and pelvic or pelvic/periaortic robotic therapeutic lymphadenectomy (rtLNE) for FIGO stage IA-IIB cervical cancer. No transition to open surgery was necessary. No intraoperative complications were noted. The postoperative complication rate was 23%. Within follow-up time (mean: 18 months) we noted one distant but no locoregional recurrence of cervical cancer. There were no deaths from cervical cancer during the observation period. We conclude that rTMMR and rtLNE is a feasible and safe technique for the treatment of compartment-defined cervical cancer.

Background Clinical characteristics of isolated, idiopathic cervical dystonia such as onset site and spread to and from additional body regions have been addressed in single-site studies with limited data and incomplete or variable dissociation of focal and segmental subtypes. Objectives To characterize clinical characteristics and demographics of isolated, idiopathic cervical dystonia in the largest standardized, multicenter cohort. Methods The Dystonia Coalition, through a consortium of 37 recruiting sites in North America, Europe and Australia recruited 1477 participants with focal (60.7%) or segmental (39.3%) cervical dystonia on examination. Clinical and demographic characteristics were evaluated in terms of the body region of dystonia onset and spread. Results Site of dystonia onset was: a) focal neck only (78.5%), b) focal onset elsewhere with later segmental spread to neck (13.3%), and c) segmental onset with initial neck involvement (8.2%).Frequency of spread from focal cervical to segmental dystonia (22.8%) was consistent with prior reports, but frequency of segmental onset with initial neck involvement was substantially higher than 3% previously reported. Cervical dystonia with focal neck onset, more than other subtypes, is associated with spread and tremor of any type. Sensory tricks were less frequent in cervical dystonia with segmental components, and segmental cervical onset occurred at an older age. Conclusions Subgroups had modest but significant differences in the clinical characteristics that may represent different clinical entities or pathophysiologic subtypes. These findings are critical for design and implementation of studies to describe, treat, or modify disease progression in idiopathic isolated cervical dystonia. PMID:27753188

High-risk human papillomaviruses (HPV), such as HPV-16, are etiologic agents of a variety of anogenital and oral malignancies, including nearly all cases of cervical cancer. Cervical cancers arising in transgenic mice that express HPV-16 E7 in an inducible manner require the continuous expression of E7 for their maintenance. However, in HPV-associated cancers in vivo, E6 and E7 invariably are coexpressed. In this study, we investigated whether cervical cancers rely on the continuous expression of E7 in the context of constitutively expressed E6. We placed the inducible HPV-16 E7 transgene onto a background in which HPV-16 E6 was constitutively expressed. In transgenic mice with high-grade cervical dysplastic lesions and cervical cancer, repressing the expression of E7 led to the regression of all cancers and the vast majority of high-grade dysplastic lesions. In addition, cervical cancers were occasionally observed in transgenic mice in which E7 was repressed and then reexpressed. Our findings indicate that even in the presence of constitutively expressed E6, the continuous expression of E7 is required for the maintenance of cervical cancers and most precancerous lesions. These data have important implications for the potential clinical use of drugs designed to inhibit the expression and/or function of E7 to treat HPV-associated cancers. ©2012 AACR.

Posterior cervical decompression is an accepted treatment for multilevel cervical spondylotic myelopathy (CSM). Each posterior technique has its own advantages and disadvantages. In the present study, we compared the functional and radiological outcomes of expansive hemilaminectomy and laminoplasty with mini titanium plate in the treatment of multilevel CSM. Forty-four patients with multilevel CSM treated with posterior cervical surgery in Department of Orthopedic Surgery, Beijing Army General Hospital from March 2011 to June 2012 were enrolled in this retrospective study. Patients were divided into two groups by surgical procedure: Laminoplasty (Group L) and hemilaminectomy (Group H). Perioperative parameters including age, sex, duration of symptoms, operative duration, and intraoperative blood loss were recorded and compared. Spinal canal area, calculated using AutoCAD ® software(Autodesk Inc., San Rafael, CA, USA), and neurological improvement, evaluated with Japanese Orthopedic Association score, were also compared. Neurological improvement did not differ significantly between groups. Group H had a significantly shorter operative duration and significantly less blood loss. Mean expansion ratio was significantly greater in Group L (77.83 ± 6.41%) than in Group H (62.72 ± 3.86%) (P < 0.01). Both surgical approaches are safe and effective in treating multilevel CSM. Laminoplasty provides a greater degree of enlargement of the spinal canal, whereas expansive hemilaminectomy has the advantages of shorter operative duration and less intraoperative blood loss.

The purpose of this study was to assess the 5-year survival and morbidity in cases with radical hysterectomy and pelvic lymphadenectomy with pre- and postoperative irradiation performed to treat Stage IA2-IIB cervical cancer. During a 10(1/2)-year period between July 1990 and December 2000, 501 consecutive radical hysterectomies with bilateral pelvic lymphadenectomy were performed by the same gynecological surgeon in Stage IA2, IB, IIA and IIB cervical cancer. The patients were treated by pre- and postoperative irradiation as well. Apart from recurrence, perioperative complications were minimal with no long-term morbidity. The absolute 5-year survival rates for the patients in Stage IA2, IB1, IB2, IIA and IIB were 94.4%, 90.7%, 84.1%, 71.1%, and 55.4%, respectively. The respective 5-year survival rates for patients without or with lymph node metastasis were 94.5% and 33.3% in Stage IB2, 81.7% and 48.7% in Stage IIA and 70.2% and 36.5% in Stage IIB, respectively. Nerve-sparing radical hysterectomy with pelvic lymph node dissection and pre- and postoperative irradiation remains the treatment of choice for most patients with early-stage and even Stage IIB cervical cancer. The radicalism and extent of lymph node dissection and parametrial resection should be individualized and tailored to tumor- and patient-related risk factors.

To study MRI and positron emission tomography (PET)/CT imaging of osteoradionecrosis (ORN) of the subaxial cervical spine, a serious long-term complication of radiation therapy (RT) for head and neck cancers that can lead to pain, vertebral instability, myelopathy and cord compression. This is a single-institution retrospective review of patients diagnosed and treated for ORN of the subaxial cervical spine following surgery and radiation for head and neck cancer. We report PET/CT imaging and MRI for four patients, each with extensive treatment for recurrent head and neck cancer. Osteomyelitis (OM) and discitis are the end-stage manifestations of ORN of the subaxial spine. ORN of the subaxial spine has variable imaging appearance and needs to be differentiated from recurrent or metastatic disease. Surgical violation of the posterior pharyngeal wall on top of the compromised vasculature in patients treated heavily with RT may pre-dispose the subaxial cervical vertebrae to ORN, with possible resultant OM and discitis. MRI and PET/CT imaging are complimentary in this setting. PET/CT images may be misinterpreted in view of the history of head and neck cancer. MRI should be utilized for definitive diagnosis of OM and discitis in view of its imaging specificity. We identify the end-stage manifestation of ORN in the sub-axial spine on PET/CT and MRI to facilitate its correct diagnosis.

To investigate the frequency of airway injury and damage to other vital structures associated with cervical bite wounds in dogs and cats and the implications for management and outcome. A retrospective search of electronic patient records was used to identify dogs and cats suffering cervical bite wounds that were presented to a large multidisciplinary veterinary hospital over a four year period. Complete records were available for 55 animals, with one animal suffering two separate injuries. Fourteen animals (25%) had injuries to vital structures, including airway injury in nine (17%) which was surgically confirmed and treated in six (11%). Airway injuries were associated with either subcutaneous or mediastinal emphysema in all affected animals. Other structures injured included the jugular vein, pharynx, oesophagus and spine. Airway injuries were treated with primary repair in five animals and a fasciomuscular patch in one. Temporary tracheostomy was performed in three animals. Median duration of hospitalisation was one day (0-19) with 53 animals (54 cases) (96%) surviving to discharge. Long-term follow-up (16-114 months) revealed that 43 of 49 animals were alive with six that died due to unrelated reasons. Cervical bite wounds are associated with significant injury to vital structures. Up to 17% of animals may have injury to their airway. Identification and treatment of airway injury is vital and was associated with an excellent outcome in six animals.

Cervical intraepithelial neoplasia (CIN) stage 2-3 is a premalignant lesion that can progress to cervical cancer in 10-20 years if untreated. To conduct systematic reviews of randomized and nonrandomized studies for effects of cryotherapy, loop electrosurgical excision procedure (LEEP), and cold knife conization (CKC) as treatment for CIN 2-3. Medline, Embase, and other databases were searched to February 2012 for benefits, and to July 2012 for harms. Additionally, experts were contacted. Keywords for CIN, cervical cancer, and the treatments were used. Studies of nonpregnant women 18 years or older not previously treated for CIN were included. Two investigators independently screened and collected data. Relative risks and proportions were calculated and evidence assessed using GRADE (Grading of Recommendations Assessment, Development and Evaluation). Recurrence rate was 5.3% 12 months after cryotherapy or LEEP, and 1.4% after CKC. There seemed to be little or no differences in frequency of complications after LEEP or cryotherapy, but they occurred more often after CKC. Evidence suggests premature delivery is most common with CKC, but it also occurs after LEEP and cryotherapy. Despite a comprehensive search, there is very low quality evidence and often no evidence for important outcomes, including reproductive outcomes and complications. Studies assessing these outcomes are needed. Copyright © 2015 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd. All rights reserved.

The evaluation of 5-year results obtained through 2 radiochemotherapy (RCT) regimens: cisplatin (CDDP), 20 mg/m × 5 days every 21 days; and CDDP, 40 mg/m per week in locally advanced cervical carcinoma. In this single-institution prospective randomized phase 3 study, 326 patients with stage IIB to IIIB squamous cell cervical carcinoma treated from March 2003 to March 2005 were included. One hundred sixty patients (49%) had stage IIB cervical carcinoma, 103 patients (31.5%) had stage IIIA cervical carcinoma, and 63 patients (19.5%) had stage IIIB cervical carcinoma. The patients were randomly assigned to 2 therapeutic arms: 164 patients in arm A (5 days) concurrent RCT with CDDP, 20 mg/m per day, days 1 to 5 every 21 days; and 162 patients in arm B (weekly), concurrent RCT with CDDP, 40 mg/m per day weekly. All patients were treated with external beam radiotherapy on the abdominopelvic region using 15-MV x-rays and a cervical boost using the x-rays arch technique or medium-dose-rate intracavitary brachytherapy. The 5-year survival rate obtained through the 2 RCT regimens are not statistically different, even if a tendency of superiority can be observed in the 5-day arm as far as overall survival (78% in arm A vs 72% in arm B; p = 0.14) and disease-free survival (73% in arm A and 69% in arm B; p = 0.09) are concerned. Five-year local relapse-free survival was significantly superior in the 5-day CDDP arm (87%) in comparison with the weekly CDDP arm (77%); p < 0.01. In the 5-day arm, local relapse rate was twice lower, 21/164 (13%), compared with the weekly arm, 40/162 (25%); p < 0.01). Distance failures were identical in the 2 therapeutic groups: 22/164 (13%) and 21/162 (13%), respectively, which shows the superiority of arm A regarding local control. The results of our study demonstrate that RCT with cisplatin, 20 mg/m × 5 days every 21 days, is superior regarding local efficacy and is less toxic compared with the weekly chemotherapy regimen.

Objective The aim of this study was to evaluate the efficacy and safety of anterior cervical corpectomy and fusion (ACCF) and anterior cervical discectomy and fusion (ACDF) for treating two-adjacent-level cervical spondylosis myelopathy (CSM). Design A meta-analysis of the two anterior fusion methods was conducted. The electronic databases of PubMed, the Cochrane Central Register of Controlled Trials, ScienceDirect, CNKI, WANFANG DATA and CQVIP were searched. Quality assessment of the included studies was evaluated using the Cochrane Risk of Bias Tool and the Methodological Index for Non-Randomised Studies criteria. Pooled risk ratios of dichotomous outcomes and standardised mean differences (SMDs) of continuous outcomes were generated. Using the χ2 and I2 tests, the statistical heterogeneity was assessed. Subgroup and sensitivity analyses were also performed. Participants Nine eligible trials with a total of 631 patients and a male-to-female ratio of 1.38:1 were included in this meta-analysis. Inclusion criteria Randomised controlled trials (RCTs) and non-randomised controlled trials that adopted ACCF and ACDF to treat two-adjacent-level CSM were included. Results No significant differences were identified between the two groups regarding hospital stay, the Japanese Orthopaedic Association (JOA) score, visual analogue scale (VAS) scores for neck and arm pain, total cervical range of motion (ROM), fusion ROM, fusion rate, adjacent-level ossification and complications, while ACDF had significantly less bleeding (SMD=1.14, 95% CI (0.74 to 1.53)); a shorter operation time (SMD=1.13, 95% CI (0.82 to 1.45)); greater cervical lordosis, total cervical (SMD=−2.95, 95% CI (−4.79 to −1.12)) and fused segment (SMD=−2.24, 95% CI (−3.31 to −1.17)); higher segmental height (SMD=−0.68, 95% CI (−1.03 to −0.34)) and less graft subsidence (SMD=0.40, 95% CI (0.06 to 0.75)) compared to ACCF. Conclusions The results suggested that ACDF has more advantages compared to ACCF. However, additional high-quality RCTs and a longer follow-up duration are needed. PMID:25031189

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

Some patients with fibromyalgia also exhibit the neurological signs of cervical myelopathy. We sought to determine if treatment of cervical myelopathy in patients with fibromyalgia improves the symptoms of fibromyalgia and the patients’ quality of life. A non-randomized, prospective, case control study comparing the outcome of surgical (n = 40) versus non-surgical (n = 31) treatment of cervical myelopathy in patients with fibromyalgia was conducted. Outcomes were compared using SF-36, screening test for somatization, HADS, MMPI-2 scale 1 (Hypochondriasis), and self reported severity of symptoms 1 year after treatment. There was no significant difference in initial clinical presentation or demographic characteristics between the patients treated by surgical decompression and those treated by non-surgical means. There was a striking and statistically significant improvement in all symptoms attributed to the fibromyalgia syndrome in the surgical patients but not in the non-surgical patients at 1 year following the treatment of cervical myelopathy (P ≤ 0.018–0.001, Chi-square or Fisher’s exact test). At the 1 year follow-up, there was a statistically significant improvement in both physical and mental quality of life as measured by the SF-36 score for the surgical group as compared to the non-surgical group (Repeated Measures ANOVA P < 0.01). There was a statistically significant improvement in the scores from Scale 1 of the MMPI-2 and the screening test for somatization disorder, and the anxiety and depression scores exclusively in the surgical patients (Wilcoxon signed rank, P < 0.001). The surgical treatment of cervical myelopathy due to spinal cord or caudal brainstem compression in patients carrying the diagnosis of fibromyalgia can result in a significant improvement in a wide array of symptoms usually attributed to fibromyalgia with attendant measurable improvements in the quality of life. We recommend detailed neurological and neuroradiological evaluation of patients with fibromyalgia in order to exclude compressive cervical myelopathy, a potentially treatable condition.

The number of elderly patients being diagnosed with cervical cancer is increasing, and the outcome of cervical cancer related to age is controversial. We conducted a retrospective analysis in patients treated for advanced cervical cancer in order to investigate patient characteristics and prognosis of older patients. Medical records were collected of 159 patients with cervical cancer who had been treated with radiotherapy or combined radiotherapy and chemotherapy from January 2007 to January 2009. The patients were divided into two age groups: (1) patients ≥65 years old, and (2) patients <65 years old. There were 52 women in group 1, 107 in group 2. Prognosis, patient characteristics, treatment, and toxicities were evaluated. With a median follow-up of 36.5 months, local control for groups 1 and 2 was 88.5% and 79.4%, respectively. Disease-free survival for the two groups was 71.2% and 67.3%; overall survival was 73.1% and 72.9%. As shown by univariate analyses, there was no statistically significant difference between the two groups (P > 0.05). Seventy-six patients had human papillomavirus (HPV) at diagnosis (twelve women ≥65 years, 64 women ≤65 years; P = 0.000). Forty-two women tested positive for HPV 16, while 32 women tested positive for HPV 18 respectively. Pelvic and/or paraaortic lymph-node metastasis was found in 25 patients (eight in group 1, 17 in group 2; P = 0.960) on computed tomography scan. Of the 159 patients analyzed, sixteen patients (16/52) in group 1 received concurrent chemotherapy, while 96 (96/107) in group 2 completed that treatment. Cervical cancer has the same prognosis in old and young women. Age may not be an independent increased risk of death in women with cervical cancer, and the age-group is at lower risk for virulent HPV strands (HPV 16/18) compared to younger patients. Treatment recommendations were implemented less often for older patients. Radiotherapy remained the most common treatment chosen for elderly patients. This confirms that there is a stronger need to pay attention to the elderly patient.

Cervical cancer is the fourth most frequent malignancy affecting women worldwide, but drug resistance and toxicities remain a major challenge in chemotherapy. The use of natural compounds is promising because they are less toxic and able to target multiple signaling pathways. The 1'S-1'-acetoxychavicol acetate (ACA), a natural compound isolated from wild ginger Alpinia conchigera , induced cytotoxicity on various cancer cells including cervical cancer. MicroRNAs (miRNAs) are short noncoding RNAs that regulate numerous biological processes, such as apoptosis and chemosensitivity. Past studies reported that miR-629 is upregulated in many cancers, and its expression was altered in ACA-treated cervical cancer cells. However, the role of miR-629 in regulating sensitivity toward ACA or other anticancer agents has not been reported. Hence, this study aims to investigate the role of miR-629 in regulating response toward ACA on cervical cancer cells. The miR-629 expression following transfection with miR-629 hairpin inhibitor and hairpin inhibitor negative control was measured using quantitative real-time polymerase chain reaction (RT-qPCR). The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to investigate sensitivity toward ACA. Apoptosis was detected using Annexin V/propidium iodide and Caspase 3/7 assays. The gene target for miR-629 was identified using miRNA target prediction programs, luciferase reporter assay and Western blots. Gene overexpression studies were performed to evaluate its role in regulating response toward ACA. Transfection with miR-629 hairpin inhibitor downregulated its expression in both cervical cancer cell lines. Suppression of miR-629 increased sensitivity toward ACA by reducing cell proliferation and inducing apoptosis. Luciferase reporter assay confirmed RSU1 as a direct target of miR-629. Overexpression of miR-629 decreased RSU1 protein expression, while inhibition of miR-629 increased RSU1 protein expression. Overexpression of RSU1 augmented antiproliferative and apoptosis-inducing effects of ACA. Our findings showed that combination of ACA with miR-629 and RSU1 may provide a potential strategy in treating cervical cancer.

Cervical cancer is the second most common cancer in women. Standard treatment options available for cervical cancer including chemotherapy, surgery and radiation therapy associated with their own side effects and toxicities. Tumor-targeted delivery of anticancer drugs is perhaps one of the most appropriate strategies to achieve optimal outcomes from treatment and improve quality of life. Recently nanocarriers based drug delivery systems owing to their unique properties have been extensively investigated for anticancer drug delivery. In addition to that addressing the anatomical significance of cervical cancer, various local drug delivery strategies for the cancer treatment are introduced like: gels, nanoparticles, polymeric films, rods and wafers, lipid based nanocarrier. Localized drug delivery systems allows passive drug targeting results in high drug concentration at the target site. Further they can be tailor made to achieve both sustained and controlled release behavior, substantially improving therapeutic outcomes and minimizing side effects. This review summarizes the meaningful advances in drug delivery strategies to treat cervical cancer. Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.

High risk HPV infection is a causative factor of cervical cancer. The constitutive expression of HPV E6-E7 genes is important for the maintenance of cancer phenotypes. The cellular transcription co-activator p300 plays a crucial role in the regulation of HPV genes thus it was targeted for the inhibition of HPV-associated cervical cancer. In the present study, HPV positive cervical cells were treated with C646, a selective inhibitor of p300, to investigate its influence on HPV E6-E7 expression and cancer cell growth. Results of RT-qPCR, Western-blot and promoter activity assays showed that C646 inhibited the transcription of HPV E6-E7, which was accompanied with the accumulation of p53 protein. Meanwhile, cell proliferation was suppressed, glucose metabolism was disrupted and apoptosis was induced via the intrinsic pathway. Generally, the anti-cervical cancer potential of C646 was demonstrated and a novel mechanism was proposed in this study. Copyright © 2017. Published by Elsevier B.V.

We report a case of cervical pyogenic spondylitis complicated by epidural abscess with quadriplegia during treatment of severe burns. The patient was a 49-year-old man with 3rd-degree burns to 20% of his body, involving the lower extremities. We performed escharectomy of the 3rd-degree necrosis on days 7 and 16, followed by the first skin graft on day 23. Pseudomonas aeruginosa was detected in the postoperative graft wound culture. On day 23 after the skin graft, he became febrile and began to experience cervical pain and muscle weakness of the extremities. By day 24, quadriplegia had developed. A cervical vertebral magnetic resonance imaging (MRI) scan showed pyogenic spondylitis with an epidural abscess, which was causing the quadriplegia. We treated the patient by performing curettage of the pyogenic lesion and anterior fixation of the cervical vertebral bodies. The fact that P. aeruginosa was detected in the pyogenic focus culture indicated that burn wound sepsis was responsible for the infection. This case reinforces that acting on a strong suspicion helps to establish a diagnosis and initiate appropriate treatment early.

The optimal treatment for cervical cancer is still a controversial matter: in the last two decades a lot of different modalities combining surgery, radiotherapy (RT) and chemotherapy (CHT) have been suggested and analysed in clinical trials. Nevertheless, analysis of treatment in cancer patients should be directed not only to survival, but also to the cost of complications and quality of life. In June 1988, a French-Italian co-operative group set up a glossary in which the complications of the treatment of cervical cancer are described and ranked. Nowadays, this is the only international system based upon an accurate description of symptoms and signs of complications following multidisciplinary treatment. The glossary was based on our previous experience in treating patients by surgery alone, RT or their combinations. Recently multimodality treatment includes also CHT. The aim of the present study was to verify whether the glossary is still a useful clinical instrument in outcome evaluation of cervical cancer treatment. The analysis has been done on a retrospective consecutive series of 579 patients affected by cervical cancer, treated in five Italian institutions. A minimum of 12 months follow up was required. All medical records of the patients enrolled, were examined by two independent reviewers in order to classify the complications according to the glossary. Out of 579 patients 319 (55.1%) were free of complications and 260 (44.9%) experienced at least one complication. We found 436 complications. The distribution by Grade was: G1 58.9%, G2 27.5%, G3 13.5%. We had no fatal complication (G4). The glossary included all observed complications, except for pulmonary fibrosis. The glossary is still a useful instrument in evaluating the outcome of cervical cancer treatment, whatever the therapy, and should be considered in quality of life assessment.

Objective In this study, we investigated whether regular use of aspirin or acetaminophen was associated with risk of cervical cancer in women treated at an American cancer hospital. Methods This case-control study included 328 patients with cervical cancer and 1,312 controls matched on age and decade enrolled. Controls were women suspected of having but not ultimately diagnosed with a neoplasm. Analgesic use was defined as regular (at least once per week for ≥6 months), frequent (≥7 tablets/week), very long term (≥11 years), or frequent, long term (≥7 tablets per week for ≥5 years). Results Compared to nonusers, frequent aspirin use was associated with decreased odds of cervical cancer (odds ratio, 0.53; 95%confidence interval, 0.29–0.97). A slightly larger association was observed with frequent, long-term use of aspirin (odds ratio, 0.46; 95% confidence interval, 0.22–0.95). Acetaminophen use was not associated with the risk of cervical cancer. Conclusions Our findings suggest that frequent and frequent, long-term use of aspirin is associated with decreased odds of cervical cancer. To our knowledge, this is the first US-based study examining these associations. Given the widespread use of nonsteroidal anti-inflammatory drugs and acetaminophen worldwide, further investigations of the possible role of analgesics in cervical cancer, using a larger sample size with better-defined dosing regimens, are warranted.

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

Objectives. We analyzed cervical cancer incidence and mortality data in American Indian and Alaska Native (AI/AN) women compared with women of other races. Methods. We improved identification of AI/AN race, cervical cancer incidence, and mortality data using Indian Health Service (IHS) patient records; our analyses focused on residents of IHS Contract Health Service Delivery Area (CHSDA) counties. Age-adjusted incidence and death rates were calculated for AI/AN and White women from 1999 to 2009. Results. AI/AN women in CHSDA counties had a death rate from cervical cancer of 4.2, which was nearly twice the rate in White women (2.0; rate ratio [RR] = 2.11). AI/AN women also had higher incidence rates of cervical cancer compared with White women (11.0 vs 7.1; RR = 1.55) and were more often diagnosed with later-stage disease (RR = 1.84 for regional stage and RR = 1.74 for distant stage). Death rates decreased for AI/AN women from 1990 to 1993 (−25.8%/year) and remained stable thereafter. Conclusions. Although rates decreased over time, AI/AN women had disproportionately higher cervical cancer incidence and mortality. The persistently higher rates among AI/AN women compared with White women require continued improvements in identifying and treating cervical cancer and precancerous lesions. PMID:24754650

Meta-analysis of 4 prospective randomized controlled Food and Drug Administration (FDA) Investigational Device Exemption (IDE) clinical trials. To maximize the information available from 4 IDE studies by analyzing the combined outcomes of cervical arthroplasty versus fusion at 24-month follow-up. To date, 4 randomized clinical trials have been completed in the United States under FDA IDE protocols to study cervical arthroplasty. Each trial reported arthroplasty to be at least as successful as fusion controls based on noninferiority trial designs. However, sample sizes in any given trial may not be sufficient to demonstrate superiority of treatment effect. Meta-analysis enables pooling of results from comparable trials, which may lead to more precise and statistically significant estimates of treatment effect. Four cervical arthroplasty randomized clinical trials with comparable enrollment criteria and outcome measures were conducted independently by 3 separate sponsors to study the following devices: Bryan, Prestige, ProDisc-C, and PCM cervical disc replacements. A total of 1608 patients were treated across 98 investigative sites. Data were available for 1352 treated patients, of which 1226 were evaluable at 24 months. Assessments included clinical success definitions based on neck disability index, maintenance or improvement of neurological status, subsequent surgery or intervention at the index level (survivorship), and a composite score comprising these as well as serious device-related adverse events. Trial endpoint comparisons were made at 24 months postoperatively. For each endpoint, a random-effects meta-analysis was performed to compare the success rates of cervical arthroplasty with anterior cervical discectomy and fusion (ACDF). Also, supportive frequentist and bayesian analyses were performed. The pooled primary overall success results indicated a statistically significant treatment effect favoring arthroplasty compared with ACDF. Overall success was achieved by 77.6% of the arthroplasty patients and by 70.8% of the ACDF patients (pooled odds ratio [OR]: 0.699, 95% confidence interval [CI]: 0.539-0.908, P = 0.007). The results of the individual subcomponent meta-analyses, all of which favored arthroplasty, were neck disability index success (OR: 0.786, 95% CI: 0.589-1.050, P = 0.103), neurological status (OR: 0.552, 95% CI: 0.364-0.835, P = 0.005), and survivorship (OR: 0.510, 95% CI: 0.275-0.946, P = 0.033). Only the survivorship endpoint suggested low heterogeneity. These findings suggest that cervical arthroplasty is superior to ACDF in overall success, neurological success, and survivorship outcomes at 24 months postoperatively.

Cardiac magnetic resonance (CMR) imaging is increasingly important in the diagnostic work-up of a wide range of heart diseases, including those with arrhythmogenic potential. To assess the added value of CMR in etiological diagnosis of ventricular arrhythmias after an inconclusive conventional investigation. Patients undergoing CMR between 2005 and 2011 for investigation of ventricular arrhythmias were included (n=113). All had documented arrhythmias. Those with a definite diagnosis from a previous investigation and those with evidence of coronary artery disease (acute coronary syndrome, typical angina symptoms, increase in biomarkers or positive stress test) were excluded. CMR results were considered relevant when they fulfilled diagnostic criteria. Of the 113 patients, 57.5% were male and mean age was 41.7 ± 16.2 years. Regarding the initial arrhythmia, 38.1% had ventricular fibrillation/sustained ventricular tachycardia (VF/VT) and 61.9% had less complex ventricular ectopy. CMR imaging showed criteria of a specific diagnosis in 42.5% of patients, was totally normal in 36.3%, and showed non-specific alterations in the remainder. In VF/VT patients, specific criteria were found in 60.4%, and in 31.4% of those with less complex ectopy. The most frequent diagnoses were arrhythmogenic right ventricular dysplasia, ventricular non-compaction and myopericarditis. It is worth noting that, although there was no evidence of previous coronary artery disease, 6.2% of patients had a late gadolinium enhancement distribution pattern compatible with myocardial infarction. CMR gives additional and important information in the diagnostic work-up of ventricular arrhythmias after an inconclusive initial investigation. The proportion of patients with diagnostic criteria was 42.5% (60.0% in those with VF/VT), and CMR was completely normal in 36.6%. Copyright © 2012 Sociedade Portuguesa de Cardiologia.

Intermittent change in p-wave discernibility during periods of ectopy and sinus arrhythmia is a cause of inappropriate atrial fibrillation (AF) detection in insertable cardiac monitors (ICM). To address this, we developed and validated an enhanced AF detection algorithm. Atrial fibrillation detection in Reveal LINQ ICM uses patterns of incoherence in RR intervals and absence of P-wave evidence over a 2-min period. The enhanced algorithm includes P-wave evidence during RR irregularity as evidence of sinus arrhythmia or ectopy to adaptively optimize sensitivity for AF detection. The algorithm was developed and validated using Holter data from the XPECT and LINQ Usability studies which collected surface electrocardiogram (ECG) and continuous ICM ECG over a 24-48 h period. The algorithm detections were compared with Holter annotations, performed by multiple reviewers, to compute episode and duration detection performance. The validation dataset comprised of 3187 h of valid Holter and LINQ recordings from 138 patients, with true AF in 37 patients yielding 108 true AF episodes ≥2-min and 449 h of AF. The enhanced algorithm reduced inappropriately detected episodes by 49% and duration by 66% with <1% loss in true episodes or duration. The algorithm correctly identified 98.9% of total AF duration and 99.8% of total sinus or non-AF rhythm duration. The algorithm detected 97.2% (99.7% per-patient average) of all AF episodes ≥2-min, and 84.9% (95.3% per-patient average) of detected episodes involved AF. An enhancement that adapts sensitivity for AF detection reduced inappropriately detected episodes and duration with minimal reduction in sensitivity. © The Author 2017.

We examined the role of intratumoral metabolic heterogeneity on 18F-FDG PET during concurrent chemoradiotherapy (CCRT) in predicting survival outcomes for patients with cervical cancer. This prospective study consisted of 44 patients with bulky (≥ 4 cm) cervical cancer treated with CCRT. All patients underwent serial 18F-FDG PET studies. Primary cervical tumor standardized uptake values, metabolic tumor volume, and total lesion glycolysis (TLG) were measured in pretreatment and intra-treatment (2 weeks) PET scans. Regional textural features were analyzed using the grey level run length encoding method (GLRLM) and grey-level size zone matrix. Associations between PET parameters and overall survival (OS) were tested by Kaplan-Meier analysis and Cox regression model. In univariate analysis, pretreatment grey-level nonuniformity (GLNU) > 48 by GLRLM textural analysis and intra-treatment decline of run length nonuniformity < 55% and the decline of TLG (∆TLG) < 60% were associated with significantly worse OS. In multivariate analysis, only ∆TLG was significant (P = 0.009). Combining pretreatment with intra-treatment factors, we defined the patients with a initial GLNU > 48 and a ∆TLG ≤ 60% as the high-risk group and the other patients as the low-risk. The 5-year OS rate for the high-risk group was significantly worse than that for the low-risk group (42% vs. 81%, respectively, P = 0.001). The heterogeneity of intratumoral FDG distribution and the early temporal change in TLG may be an important predictor for OS in patients with bulky cervical cancer. This gives the opportunity to adjust individualized regimens early in the treatment course. PMID:27508103

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

Cervical cancer cells (HeLa) response to photodynamic therapy using a zinc phthalocyanine photosensitizer.

Cervical cancer is the most common gynecological malignancy worldwide, and the leading cause of cancer related deaths among females. Conventional treatment for early cervical cancer is radical hysterectomy. In locally advanced cancer the treatment of choice is concurrent chemo radiation. Although such treatment methods show promise, they do have adverse side effects. To minimize these effects, as well as prevent cancer re-occurrence, new treatment methods are being investigated. Photodynamic therapy (PDT) involves the selective uptake of a photosensitizer (PS) by cancer cells, illumination with light of an appropriate wavelength that triggers a photochemical reaction leading to the generation of reactive oxygen and subsequent tumor regression. The effect of PDT on a cervical cancer cell line (HeLa) was assessed by exposing cultured cells to a sulphonated zinc phthalocyanine PS (ZnPcS mix ) and irradiating the cells using a 673nm diode laser. The effects were measured using the Trypan blue viability assay, adenosine triphosphate assay (ATP) luminescence assay for proliferation, Lactate Dehydrogenase (LDH) membrane integrity cytotoxicity assay, and fluorescent microscopy to assess PS cellular localization and nuclear damage. Fluorescent microscopy revealed localization of the PS in the cytoplasm and perinuclear region of HeLa cells. PDT treated cellular responses showed dose dependent structural changes, with decreased cell viability and proliferation, as well as considerable membrane damage. Hoechst stained cells also revealed DNA damage in PDT treated cells. The final findings from this study suggest that ZnPcS mix is a promising PS for the PDT treatment of cervical cancer in vitro, where a significant 85% cellular cytotoxicity with only 25% cellular viability was noted in cells which received 1μM ZnPcS mix when an 8J/cm 2 fluence was applied.

Cervical radicular syndrome (CRS) due to a herniated disc can be safely treated by surgical decompression of the spinal root. In the vast majority of cases this relieves pain in the arm and restores function. However, conservative treatment also has a high chance on relieving symptoms. The objective of the present study is to evaluate the (cost-) effectiveness of surgery versus prolonged conservative care during one year of follow-up, and to evaluate the timing of surgery. Predisposing factors in favour of one of the two treatments will be evaluated. Patients with disabling radicular arm pain, suffering for at least 2 months, and an MRI-proven herniated cervical disc will be randomised to receive either surgery or prolonged conservative care with surgery if needed. The surgical intervention will be an anterior discectomy or a posterior foraminotomy that is carried out according to usual care. Surgery will take place within 2-4 weeks after randomisation. Conservative care starts immediately after randomisation. The primary outcome measure is the VAS for pain or tingling sensations in the arm one year after randomisation. In addition, timing of surgery will be studied by correlating the primary outcome to the duration of symptoms. Secondary outcome measures encompass quality of life, costs and perceived recovery. Predefined prognostic factors will be evaluated. The total follow-up period will cover two years. A sample size of 400 patients is needed. Statistical analysis will be performed using a linear mixed model which will be based on the 'intention to treat' principle. In addition, a new CRS questionnaire for patients will be developed, the Leiden Cervical Radicular Syndrome Functioning (LCRSF) scale. The outcome will contribute to better decision making for the treatment of cervical radicular syndrome. NTR3504.

Purpose To evaluate the potential of gene expression signatures to predict response to treatment in locally advanced cervical cancer treated with definitive chemotherapy and radiation. Experimental Design Tissue biopsies were collected from patients participating in Radiation Therapy Oncology Group (RTOG) 0128, a phase II trial evaluating the benefit of celecoxib in addition to cisplatin chemotherapy and radiation for locally advanced cervical cancer. Gene expression profiling was done and signatures of pretreatment, mid-treatment (before the first implant), and “changed” gene expression patterns between pre- and mid-treatment samples were determined. The ability of the gene signatures to predict local control versus local failure was evaluated. Two-group t test was done to identify the initial gene set separating these end points. Supervised classification methods were used to enrich the gene sets. The results were further validated by leave-one-out and 2-fold cross-validation. Results Twenty-two patients had suitable material from pretreatment samples for analysis, and 13 paired pre- and mid-treatment samples were obtained. The changed gene expression signatures between the pre- and mid-treatment biopsies predicted response to treatment, separating patients with local failures from those who achieved local control with a seven-gene signature. The in-sample prediction rate, leave-one-out prediction rate, and 2-fold prediction rate are 100% for this seven-gene signature. This signature was enriched for cell cycle genes. Conclusions Changed gene expression signatures during therapy in cervical cancer can predict outcome as measured by local control. After further validation, such findings could be applied to direct additional therapy for cervical cancer patients treated with chemotherapy and radiation. PMID:19509178

The Cervical and Breast Cancer Prevention (CECAP) Project sought to develop a national model for cervical cancer prevention in Indonesia based on visual inspection with acetic acid (VIA) to detect abnormal changes in the cervix. The purpose of this study was to evaluate a pilot project introducing VIA and cryotherapy in Indonesia and to identify lessons learned that could be applied to the national scale-up of cervical cancer prevention services. Fifty-four months (July 2007 to December 2011) of service records at 17 health centers were abstracted and analyzed. The data were used to calculate the proportion of all women aged 30-50 who received VIA screening, the VIA-positive rate, the treatment rate, and the interval between screening and treatment. The 45 050 women screened during the project included 24.4% of the total female population in the target age group in the catchment area. Throughout the 5-year project, 83.1% of VIA-positive women sought cryotherapy. During the last 18 months of the project, after data collection tools were revised to more accurately reflect when cryotherapy was received, 13% of women were treated on the same day that they were screened. Among the 74% of women treated within 1 month of screening, the mean interval between screening and treatment was 7.2 days. As cervical cancer prevention services are scaled up throughout Indonesia, changes in the service delivery model and program management are needed to increase screening coverage, promote a single-visit approach, and ensure the quality of services. © 2013 The Authors.

Manipulative techniques have shown promising results for relief of tension-type headache (TTH), however prior studies either lacked a control group, or suffered from poor methodological quality. The aim of this study was to compare the effect of spinal manipulation combined with massage versus massage alone on range of motion of the cervical spine, headache frequency, intensity and disability in patients with TTH. Randomized, single-blinded, controlled clinical trial. University clinic. We enrolled 105 subjects with TTH. Participants were divided into two groups: 1) manipulation and massage; 2) massage only (control). Four treatment sessions were applied over four weeks. The Headache Disability Inventory (HDI) and range of upper cervical and cervical motion were evaluated at baseline, immediately after the intervention and at a follow-up, 8 weeks after completing the intervention. Both groups demonstrated a large (ƒ=1.22) improvement on their HDI scores. Those that received manipulation reported a medium-sized reduction (ƒ=0.33) in headache frequency across all data points (P<0.05) compared to the control group. Both groups showed a large within-subject effect for upper cervical extension (ƒ=0.62), a medium-sized effect for cervical extension (ƒ=0.39), and large effects for upper cervical (ƒ=1.00) and cervical (ƒ=0.27) flexion. The addition of manipulation resulted in larger gains of upper cervical flexion range of motion, and this difference remained stable at the follow-up. These findings support the benefit of treating TTH with either massage or massage combined with a manipulative technique. However, the addition of manipulative technique was more effective for increasing range of motion of the upper cervical spine and for reducing the impact of headache. Although massage provided relief of headache in TTH sufferers, when combined with cervical manipulation, there was a stronger effect on range of upper cervical spine motion.

Trichomonas vaginalis induces apoptosis in host cells through various mechanisms; however, little is known about the relationship between apoptosis, reactive oxygen species (ROS), and NF-κB signaling pathways in the cervical mucosal epithelium. Here, we evaluated apoptotic events, ROS production, and NF-κB activity in T. vaginalis-treated cervical mucosal epithelial SiHa cells, with or without specific inhibitors, using fluorescence microscopy, DNA fragmentation assays, subcellular fractionation, western blotting, and luciferase reporter assay. SiHa cells treated with live T. vaginalis at a multiplicity of infection of 5 (MOI 5) for 4 h produced intracellular and mitochondrial ROS in a parasite-load-dependent manner. Incubation with T. vaginalis caused DNA fragmentation, cleavage of caspase 3 and PARP, and release of cytochrome c into the cytoplasm. T. vaginalis-treated SiHa cells showed transient early NF-κB p65 nuclear translocation, which dramatically dropped at 4 h after treatment. Suppression of NF-κB activity was dependent on parasite burden. However, treatment with the ROS scavenger, N-acetyl-C-cysteine (NAC), reversed the effect of T. vaginalis on apoptosis and NF-κB inactivation in SiHa cells. Taken together, T. vaginalis induces apoptosis in human cervical mucosal epithelial cells by parasite-dose-dependent ROS production through an NF-κB-regulated, mitochondria-mediated pathway.

Spinal intramedullary arteriovenous malformations are uncommon and a challenging type of neurosurgical entities. They are rarely located to cervical segment. On the other hand, although hemangiomas are relatively common bone tumors, cervical involvement is again rare and clinically significant ones are infrequent. A 14 year-old-male patient referred to an academic tertiary care unit and presented with neck pain and left hand weakness. Neurological examination revealed motor strength deficit at intrinsic muscles and hyperesthesia at the left hand. Furthermore the pathological reflexes were positive on the left hand side. Imaging studies showed compression fracture, lytic changes resembling a hemangioma at C7 vertebra, and also an intramedullary vascular pathology at C5-6 level which was shown to be an intradural-intramedullary arteriovenous malformation (AVM) on digital subtraction angiography. Based on neurological and radiological findings, the decision was to treat the patient. After embolization of the AVM, the neurological condition of the patient deteriorated and immediate MRI scan of the cervical spine revealed edema of the spinal cord at the C5-6 level. Thus an emergent surgery was performed and C5-6-7 laminectomies with C5-T2 posterior fixation and arthrodesis were implemented. A second stage operation was carried out as C7 corpectomy with a distractable titanium cage 2 weeks after initial surgery. A follow-up evaluation at five years revealed 4/5 motor strength on his left intrinsic hand muscles and mild hyperactive deep tendon reflexes. Imaging studies at the postoperative period showed stable placement of the construct and no evidence of contrast enhancement at the C5-6 level inside the spinal cord. A rare case of multiple pathologies affecting the cervical spine, coincidentally diagnosed after a pathological fracture during a bicycle accident as vertebral hemangioma and intradural-intramedullary AVM that was successfully treated with early detection, have been presented. One should assess such patients under multidisciplinary fashion and treat on a case-by-case basis for achieving the best results in patient care.

Introduction: Upper cervical injuries (UCI) have a wide range of radiological and clinical presentation due to the unique complex bony, ligamentous and vascular anatomy. We recently proposed a rational approach in an attempt to unify prior classification system and guide treatment. In this paper, we evaluate the clinical results of our algorithm for UCI treatment. Materials and Methods: A prospective cohort series of patients with UCI was performed. The primary outcome was the AIS. Surgical treatment was proposed based on our protocol: Ligamentous injuries (abnormal misalignment, facet perched or locked, increase atlanto-dens interval) were treated surgically. Bone fractures without ligamentous injuries were treated with a rigid cervical orthosis, with exception of fractures in the dens base with risk factors for non-union. Results: Twenty-three patients treated initially conservatively had some follow-up (mean of 171 days, range from 60 to 436 days). All of them were neurologically intact. None of the patients developed a new neurological deficit. Fifteen patients were initially surgically treated (mean of 140 days of follow-up, ranging from 60 to 270 days). In the surgical group, preoperatively, 11 (73.3%) patients were AIS E, 2 (13.3%) AIS C and 2 (13.3%) AIS D. At the final follow-up, the American Spine Injury Association (ASIA) score was: 13 (86.6%) AIS E and 2 (13.3%) AIS D. None of the patients had neurological worsening during the follow-up. Conclusions: This prospective cohort suggested that our UCI treatment algorithm can be safely used. Further prospective studies with longer follow-up are necessary to further establish its clinical validity and safety. PMID:25788816

Annually approximately 160 new cervical cancers are diagnosed in Finland. Screening has decreased both incidence and mortality by 80%. Both primary HPV-testing and Pap smear can be used in screening. In the future HPV vaccination will decrease the number of cervical cancers. Abnormal findings in Pap smears indicate management. LSIL lesions are followed up especially among young women and HSIL lesions treated. Follow-up after treatment should be reliably arranged, because increased risk of cancer remains ever after treatment.

Treatment of cervical cancer is often effective but at the cost of the woman's fertility. Ovarian transposition with subsequent oocyte retrieval and surrogate pregnancy can enable these patients to become genetic parents. We present the third reported such case. A 22-year-old woman was diagnosed with bulky, stage IB cervical cancer. Following transposition of both ovaries to the upper abdomen, she underwent pelvic irradiation followed by total abdominal hysterectomy. Eleven years later she presented for assisted reproduction. Two oocytes were retrieved following ovarian stimulation and transcutaneous, abdominal oocyte retrieval. One embryo was transferred to the gestational surrogate, resulting in a single intrauterine pregnancy and successful delivery at term. These procedures can preservefertility while successfully treating cervical cancer.

Open-door expansile cervical laminoplasty (ODECL) is an effective surgical technique in the treatment of multilevel cervical spondylotic myelopathy. In the present study, we reviewed the safety and short-term neurological outcome after expansile cervical laminoplasty in the treatment of acute central cord syndrome. We retrospectively reviewed our database over a 3-year period (January 1997-January 2001) and identified 69 surgically treated cervical spinal cord injuries, including 29 cases of acute traumatic central cord syndrome (ATCCS). Fifteen of these patients underwent expansile cervical laminoplasty, whereas 14 did not because of radiographic evidence of sagittal instability. We collected data on the preoperative and the immediate postoperative and 3-month neurological examinations. Neurological function was assessed using the Asia Spinal Injury Association (ASIA) grading system. We also reviewed the occurrence of complications and short-term radiological stability after the index procedure. The median age was 56 years. All patients had hyperextension injuries with underlying cervical spondylosis and stenosis in the absence of overt fracture or instability. The average delay from injury to surgery was 3 days. The preoperative ASIA grade scale was grade C, 8 patients, and grade D, 7 patients. There were no cases of immediate postoperative deterioration or at 3 months follow-up. Neurological outcome: 71.4% (10/14) of patients improved 1 ASIA grade when examined 3 months post injury. Surgical intervention consisting of ODECL can be safely applied in the subset of patients with ATCCS without instability who have significant cervical spondylosis/stenosis. Open-door expansile cervical laminoplasty is a safe, low-morbidity, decompressive procedure, and in our patients did not produce neurological deterioration.

Cervical collar brace protection of the cervical spine at the scene of the incident is the first priority for emergency medical technicians treating patients who have sustained trauma. However, there is still controversy between over- or underprotection. The objective of this study was to survey the cervical spine injury of lightweight motorcycle accident victims and further evaluate the neck collar protection policy. We retrospectively reviewed patients who sustained lightweight motorcycle injuries, assumed to have been at a low velocity, with incidence of cervical spine damage, from a single medical center's trauma registration from 2008 to 2009. Patients were divided into 2 groups: those who were immobilized by cervical collar brace and those who were not. Of the 8633 motorcycle crash victims, 63 patients had cervical spine injury. The average of the injury severity score in these patients was 14.31 ± 8.25. There was no significant correlation of cervical spine injury between the patients who had had the neck collar applied and those who had not (χ(2), P = .896). The length of stay in intensive care unit was longer in the patients who had the neck collar applied, but the total hospital length of stay was not statistically different to the patients who did not have the neck collar applied. The incidence of cervical spinal injuries in the urban area lightweight motorcyclists is very low. Prehospital protocol for application of a cervical collar brace to people who have sustained a lightweight motorcycle accident in the urban area should be revised to avoid unnecessary restraint and possible complications.

This study was conducted to evaluate new acupuncture protocols for the clinical treatment of cervical spinal cord diseases in 19 dogs. Three treatment options containing Jing-jiaji (cervical jiaji) were developed to treat neck pain, hemiparesis, and tetraparesis depending on the severity. The interval between the neurological disease onset and treatment (duration of signs), time to improvement after treatment, and recovery time were compared in dogs by body weight, age, and dry needle acupuncture (AP) with or without electro-AP (EAP). The duration of signs was longer in dogs weighing greater than 10 kg than in those weighing less than 10 kg (p＜ 0.05). Improvement and recovery times did not vary by body weight. Additionally, improvement and recovery times did not vary by age. The improvement and recovery times were longer in the AP+EAP group than the AP group (p＜ 0.05). Acupuncture with Jing-jiaji was effective in cervical spinal cord diseases in different sized dogs and in middle-aged and senior dogs. This report standardized AP treatment containing Jing-jiaji for canine cervical problems and evaluated its effects. The newly standardized AP methodology offers clinical practitioners an effective way to improve the outcomes of cervical neurological diseases in dogs.

Cervicovaginal HIV level (CV-VL) influences HIV transmission. Plasma viral load (PVL) correlates with CV-VL, but discordance is frequent. We evaluated how PVL, behavioral, immunological, and local factors/conditions individually and collectively correlate with CV-VL. CV-VL was measured in the cervicovaginal lavage fluid (CVL) of 481 HIV-infected women over 976 person-visits in a longitudinal cohort study. We correlated identified factors with CV-VL at individual person-visits and detectable/undetectable PVL strata by univariate and multivariate linear regression and with shedding pattern (never, intermittent, persistent ≥3 shedding visits) in 136 women with ≥3 visits by ordinal logistic regression. Of 959 person-visits, 450 (46.9%) with available PVL were discordant, 435 (45.3%) had detectable PVL with undetectable CV-VL, and 15 (1.6%) had undetectable PVL with detectable CV-VL. Lower CV-VL correlated with highly active antiretroviral therapy (HAART) usage (P = 0.01). Higher CV-VL correlated with higher PVL (P < 0.001), inflammation-associated cellular changes (P = 0.03), cervical ectopy (P = 0.009), exudate (P = 0.005), and trichomoniasis (P = 0.03). In multivariate analysis of the PVL-detectable stratum, increased CV-VL correlated with the same factors and friability (P = 0.05), while with undetectable PVL, decreased CV-VL correlated with HAART use (P = 0.04). In longitudinal analysis, never (40.4%) and intermittent (44.9%) shedding were most frequent. Higher frequency shedders were more likely to have higher initial PVL [odds ratio (OR) = 2.47/log10 increase], herpes simplex virus type 2 seropositivity (OR = 3.21), and alcohol use (OR = 2.20). Although PVL correlates strongly with CV-VL, discordance is frequent. When PVL is detectable, cervicovaginal inflammatory conditions correlate with increased shedding. However, genital shedding is sporadic and not reliably predicted by associated factors. HAART, by reducing PVL, is the most reliable means of reducing cervicovaginal shedding.

Multiple aspergillus spondylitis (AS) is a life threatening infection that occurs more commonly in immunocompromised patients, and is commonly treated with antifungal agents. However, there is relatively little information available on the treatment of multiple AS. The authors encountered a 46-year-old man suffering from low back and neck pain with radiculomyelopathy after a liver transplant. The patient had concomitant multiple AS in the cervico-thoraco-lumbar spine and right hip joint, as confirmed by radiologic imaging studies. The pathological examination of a biopsy specimen revealed fungal hyphae at the cervical and lumbar spine. Anterior decompression and interbody fusion were performed for the cervical and lumbar lesions, which showed instability and related neurological symptoms. Additional antifungal therapy was also performed. The patient was treated successfully with remission of his symptoms. PMID:20404956

The aim of the present study was to evaluate the distinctions in survival and toxicity between patients with cervical cancer with common iliac node or para-aortic node involvement, who were treated with extended-field intensity-modulated radiotherapy (EF-IMRT) and patients with or without lower involved pelvic nodes, who were treated with pelvic IMRT. A total of 55 patients treated with EF-IMRT and 52 patients treated with pelvic IMRT at the Sun Yat-Sen University Cancer Center (Guangzhou, China) were retrospectively analyzed. Patients treated with EF-IMRT had the highest level of lymph node involvement to the para-aortic or common iliac nodes, while patients treated with pelvic IMRT had no para-aortic or common iliac nodes involved (P<0.001). The median follow-up time was 29.5 months. The 3-year overall survival (OS) rates of EF-IMRT and pelvic IMRT were 79.4 and 82.3% (P=0.45), respectively, and the 3-year disease-free survival (DFS) rates of EF-IMRT and pelvic IMRT were 61.0 and 73.7% (P=0.55), respectively. Cox's regression analysis revealed that EF irradiation was a protective prognostic factor for OS and DFS. A total of 16 patients in the EF-IMRT group and 13 patients in the pelvic IMRT group experienced treatment failure (P=0.67), with the patterns of failure being the same for the two groups (P=0.88). The cumulative incidence of grade 3 and 4 acute toxicities in the EF-IMRT group was 34.5%, in comparison with 19.2% in the pelvic group (P=0.048). The results of the present study suggest that patients with cervical cancer with grossly involved common iliac or para-aortic nodes should be electively subjected to EF irradiation to improve the survival and alter patterns of recurrence. Notably, EF irradiation delivered via IMRT exhibits an increased toxicity incidence, however, this remains within an acceptable range.

Evidence collection post sexual assault varies across the nation. The Ohio Department of Health has a standardized kit for evidence collection used during the forensic exams of sexual assault survivors. The protocol includes obtaining 4 swabs: 2 from the vaginal pooled fluid and 2 from the cervical area. The purpose is to determine if augmenting the state protocol with cervical os swabs and a comparison slide will improve evidentiary findings in adolescent and adult female rape survivors. A descriptive study of 30 months for sexual assault female survivors over the age of 13 treated at a level II emergency department by a trained sexual assault nurse examiner (SANE). The comparisons of cervical os specimens versus vaginal pool findings were analyzed by the Canton-Stark County Crime Laboratory (C-SCCL). Eighty-six cases were completed. After investigation, local law enforcement officials turned in 36 kits (42%) to be processed at the C-SCCL for the standard vaginal pool swabs and slide. The average estimated time interval between assault and treatment time was 20.46 hours (range, 2.83 to 80.83 hours). The average age of the survivor was 23.7 years, (range, 15 to 48). Eight percent (3/36) had only cervical os semen evidentiary findings. Forty-four percent (16/36) had positive semen evidentiary findings in vaginal pool and cervical os. Successful convictions were aided by the cervical os research study, especially because vaginal pool evidence diminishes when collected after 24 hours, but may be present longer in the cervical os.

To describe an approach to cervical brachytherapy in a patient with congenital septate uterus and locally advanced cervical carcinoma. The patient is a 34-year-old female with septate uterus presenting with pelvic pain. Workup demonstrated a stage IIB cervical adenocarcinoma with imaging evidence of an involved right external iliac lymph node. The patient received whole pelvic radiation, with concurrent weekly cisplatin (40 mg/m(2)), to a dose of 45 Gy in 25 fractions followed by a parametrial boost of 5.4 Gy and an additional nodal boost of 9 Gy. The patient was initiated on cervical brachytherapy following fraction 23 of pelvic radiation. To conform to her septated uterus, a Rotte-Y tandem was used. Additionally, 2 CT-compatible ovoids were placed in the vaginal apex to enhance dose distribution and coverage of the target volume. Each fraction of brachytherapy was performed with CT-based planning. A high-risk clinical target volume (HR-CTV) and normal structures were defined and constrained per American Brachytherapy Society (ABS) and Groupe Européen de Curiethérapie/European Society for Therapeutic Radiology and Oncology (GEC-ESTRO) guidelines. The brachytherapy dose was 27.5 Gy in 5 fractions of 5.5 Gy each, prescribed to the HR-CTV. Herein, we report the first documented case of cervical brachytherapy in a patient with septate uterus and locally advanced cervical carcinoma. Using CT-guided planning, in conjunction with the ABS and GEC-ESTRO guidelines, the patient was effectively treated with adapted cervical brachytherapy, meeting criteria for HR-CTV coverage and normal tissue tolerances.

Epidemiology of cervical cancer with special focus on India.

Cervical cancer is on the declining trend in India according to the population-based registries; yet it continues to be a major public health problem for women in India. Multifactorial causation, potential for prevention, and the sheer threat it poses make cervical cancer an important disease for in-depth studies, as has been attempted by this paper. This paper attempts to review the available knowledge regarding the epidemiology and pattern of cervical cancer; types of HPV (human papilloma virus) prevalent among cervical cancer patients and among women in general, high-risk groups such as commercial sex workers, and HIV (human immunodeficiency virus)-positive women; and the role of the national program on cancer in control efforts. The peak age of incidence of cervical cancer is 55-59 years, and a considerable proportion of women report in the late stages of disease. Specific types of oncogenic HPV-16, 18 have been identified in patients with cervical cancer. Other epidemiological risk factors are early age at marriage, multiple sexual partners, multiple pregnancies, poor genital hygiene, malnutrition, use of oral contraceptives, and lack of awareness. A multipronged approach is necessary which can target areas of high prevalence identified by registries with a combination of behavior change communication exercises and routine early screening with VIA. Sensitizing the people of the area, including menfolk, is necessary to increase uptake levels. Vaccination against types 16 and 18 can also be undertaken after taking into confidence all stakeholders, including the parents of adolescent girls. Preventing and treating cervical cancer and reducing the burden are possible by targeting resources to the areas with high prevalence.

This report describes a paediatric patient presenting with haemodynamically stable non-sustained ventricular tachycardia 1 day after minor blunt chest trauma. Initial laboratory studies, chest X-ray and echocardiography were normal; however, cardiac MRI revealed precordial haematoma, myocardial contusion and small pericardial effusion. Throughout her hospital course, she remained asymptomatic aside from frequent couplets and triplets of premature ventricular contractions. Ectopy was controlled with oral verapamil. This case highlights how significant cardiac injury may be missed with standard diagnostic algorithms. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Cellular and physiological responses to the degradation products of titanium implants are key indicators to determine the quality of biocompatibility of implant devices. The present study investigated titanium dioxide (TiO2) nanoparticle-induced cytotoxicity, apoptotic morphological modification, and apoptotic-related gene expressions in the human cervical carcinoma cells. TiO2 nanoparticle-induced cytotoxicity on cancer cells was determined by the sulphorhodamine-B assay. Apoptotic morphological modification such as nuclear fragmentation, rounding, cytoplasm shrinkage, loss of adhesion, and reduced cell volume were observed by an inverted, fluorescence, and confocal laser scanning microscope (CLSM). The DNA fragmentation study showed the occurrence of necrosis and apoptosis in nanoparticle-treated cells. The qPCR study showed the increased p53 and bax mRNA expression in the nanoparticle-treated cells compared to control. In addition, caspase 3 activity was increased in nanoparticle-treated cells, which indicates the increased auto-catalysis. Taking all these data together, it may suggest that TiO2 nanoparticle could inhibit the growth of HeLa cells.

Cervical spine injuries of variable severity are common among patients with an acute traumatic brain injury (TBI). We hypothesised that TBI patients with positive head computed tomography (CT) scans would have a significantly higher risk of having an associated cervical spine fracture compared to patients with negative head CT scans. This widely generalisable retrospective sample was derived from 3,023 consecutive patients, who, due to an acute head injury (HI), underwent head CT at the Emergency Department of Tampere University Hospital (August 2010-July 2012). Medical records were reviewed to identify the individuals whose cervical spine was CT-imaged within 1 week after primary head CT due to a clinical suspicion of a cervical spine injury (CSI) (n = 1,091). Of the whole cranio-cervically CT-imaged sample (n = 1,091), 24.7% (n = 269) had an acute CT-positive TBI. Car accidents 22.4% (n = 244) and falls 47.8% (n = 521) were the most frequent injury mechanisms. On cervical CT, any type of fracture was found in 6.6% (n = 72) and dislocation and/or subluxation in 2.8% (n = 31) of the patients. The patients with acute traumatic intracranial lesions had significantly (p = 0.04; OR = 1.689) more cervical spine fractures (9.3%, n = 25) compared to head CT-negative patients (5.7%, n = 47). On an individual cervical column level, head CT positivity was especially related to C6 fractures (p = 0.031, OR = 2.769). Patients with cervical spine fractures (n = 72) had altogether 101 fractured vertebrae, which were most often C2 (22.8, n = 23), C7 (19.8%, n = 20) and C6 (16.8%, n = 17). Head trauma patients with acute intracranial lesions on CT have a higher risk for cervical spine fractures in comparison to patients with a CT-negative head injury. Although statistically significant, the difference in fracture rate was small. However, based on these results, we suggest that cervical spine fractures should be acknowledged when treating CT-positive TBIs.

Spontaneous cervical intradural disc herniation (IDH) is a rare occurrence with limited and disparate information available regarding its presentation, diagnosis, and treatment. However, its accurate detection is vital for planning surgical treatment. In this review of the literature, we collected data from all cervical IDHs described to date. Particular attention was paid to diagnostic findings, surgical approach, and causation for cervical IDH, especially at the cervicothoracic junction. A review for cases of cervical IDH was performed via the following search criteria: ("neck"[MeSH Terms] OR "neck"[All Fields] OR "cervical"[All Fields]) AND intradural[All Fields] AND disc[All Fields]. Thirty-seven cases of cervical disc herniation were identified. Demographic variables identified included age, sex, cervical level of herniation, history of associated cervical trauma, presence of Brown-Séquard syndrome, Horner syndrome, and other neurologic findings, radiographic findings, direction of surgical approach, and postoperative outcomes. A total of 37 cases of cervical IDH were identified. Most of the cases occurred at the lower levels of the cervical spine, with 35.1% at the C5-C6 level, followed by 24.3% at C6-C7, and lower still at other levels. Of the patients reviewed, 44.4% had a previous history of trauma before manifestation of symptom, with the majority being spontaneous IDH with no previous history of trauma or spine surgery. Brown-Séquard syndrome was present in 43.2% of the patients, whereas 10.8% of patients experienced Horner syndrome. The most common presentations of IDH included quadriplegia, finger/gait ataxia, radiculopathy, and nuchal pain. The degree of neurologic recovery was not associated with patient age. Most of the cervical IDHs in the literature were treated surgically via an anterior approach, but a larger portion of patients who underwent a posterior approach had improved recovery. Cervical IDH is a rare event, with this review of the literature outlining the clinical and radiographic parameters of its presentation as well as comparing common surgical strategies for treatment. We outline theories underlying the development of cervical IDH and argue for a posterior surgical approach in which the disc herniation is sequestrated with migration. Copyright © 2017 Elsevier Inc.

Evidence is limited for outcomes of surgical versus conservative management for patients with cervical esophageal or hypopharyngeal perforations. Patients with cervical esophageal or hypopharyngeal perforations treated between 1994 and 2014 were identified using an institutional database. Outcomes were compared between patients who underwent operative drainage and those who had conservative management with broad-spectrum antibiotics and withholding oral intake. Twenty-eight patients were identified with hypopharyngeal or cervical esophageal perforations, mostly due to iatrogenic (nasogastric tube placement, endoscopy, endotracheal intubation) injuries (68%). Fourteen were treated initially with conservative management and 14 with initial surgery. Six patients failed conservative treatment and two patients failed surgical treatment. Patients managed conservatively who had eaten between injury and diagnosis (p=0.003), those who had 24 hours or more between the time of injury and diagnosis (p=0.026), and those who showed signs of systemic toxicity (p=0.001) were significantly more likely to fail conservative treatment and require surgery. No variables were significant for treatment failure in the surgical group. Of the 20 patients who ultimately underwent a surgical procedure, two required a second procedure. Patients who have eaten between the time of perforation and diagnosis, have 24 hours or more between injury and diagnosis, and those that show signs of systemic toxicity are at higher risk of failing conservative management and surgical drainage should be considered. For patients without these risk factors, a trial of conservative management can be attempted. Copyright © 2015 Elsevier Inc. All rights reserved.

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.

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

2006-01-01

Cervical spine spondylodiscitis is a rare, but serious manifestation of spinal infection. We present a retrospective study of 20 consecutive patients between 01/1994 and 12/1999 treated because of cervical spondylodiscitis. Mean age at the time of treatment was 59.7 (range 34–81) years, nine of them female. In all cases, diagnosis had been established with a delay. All patients in this series underwent surgery such as radical debridement, decompression if necessary, autologous bone grafting and instrumentation. Surgery was indicated if a neurological deficit, symptoms of sepsis, epidural abscess formation with consecutive stenosis, instability or severe deformity were present. Postoperative antibiotic therapy was carried out for 8–12 weeks. Follow-up examinations were performed a mean of 37 (range 24–63) months after surgery. Healing of the inflammation was confirmed in all cases by laboratory, clinical and radiological parameters. Spondylodesis was controlled radiologically and could be achieved in all cases. One case showed a 15°kyphotic angle in the proximal adjacent segment. Spontaneous bony bridging of the proximal adjacent segment was observed in one patient. In the other cases the adjacent segments radiologically showed neither fusion nor infection related changes. Preoperative neurological deficits improved in all cases. Residual neurological deficits persisted in three of eight cases. The results indicate that spondylodiscitis in cervical spine should be treated early and aggressive to avoid local and systemic complications. PMID:16868782

Background: Posterior cervical decompression is an accepted treatment for multilevel cervical spondylotic myelopathy (CSM). Each posterior technique has its own advantages and disadvantages. In the present study, we compared the functional and radiological outcomes of expansive hemilaminectomy and laminoplasty with mini titanium plate in the treatment of multilevel CSM. Methods: Forty-four patients with multilevel CSM treated with posterior cervical surgery in Department of Orthopedic Surgery, Beijing Army General Hospital from March 2011 to June 2012 were enrolled in this retrospective study. Patients were divided into two groups by surgical procedure: Laminoplasty (Group L) and hemilaminectomy (Group H). Perioperative parameters including age, sex, duration of symptoms, operative duration, and intraoperative blood loss were recorded and compared. Spinal canal area, calculated using AutoCAD® software (Autodesk Inc., San Rafael, CA, USA), and neurological improvement, evaluated with Japanese Orthopedic Association score, were also compared. Results: Neurological improvement did not differ significantly between groups. Group H had a significantly shorter operative duration and significantly less blood loss. Mean expansion ratio was significantly greater in Group L (77.83 ± 6.41%) than in Group H (62.72 ± 3.86%) (P < 0.01). Conclusions: Both surgical approaches are safe and effective in treating multilevel CSM. Laminoplasty provides a greater degree of enlargement of the spinal canal, whereas expansive hemilaminectomy has the advantages of shorter operative duration and less intraoperative blood loss.

Purpose: To retrospectively analyze the outcomes and prognostic factors of cervical esophageal squamous cell carcinoma (SCC) treated with intensity modulated radiation therapy (IMRT). Methods: Thirty-seven patients with cervical esophageal SCC treated with IMRT were analyzed retrospectively. They received 54–66 Gy in 27–32 fractions. Nineteen patients received concurrent (n=12) or sequential (n=7) platinum-based two drugs chemoradiotherapy. Overall survival (OS), local control rates (LCR) and prognostic factors were evaluated. Acute toxicities and patterns of first failures were observed. Results: The median follow-up was 46 months for alive patients. The l-, 3-, 4- and 5-year OS of the all patients were 83.8%, 59.1%,more » 47.5% and 32.6% respectively. The median survival time was 46 months. The l-, 3-,4- and 5-year LCR were 82.9%, 63.0%, 54.5% and 54.5%, respectively. Univariate and Multivariate analysis all showed that size of GTV was an independent prognostic factor (p=0.033, p=0.039). There were no patients with Grade 3 acute radiation esophagitis and Grade 2–4 acute pneumonitis. The local failure accounted for 70.0% of all treatment-related failures. Conclusion: IMRT is safe and effective in the treatment of cervical esophageal squamous cell carcinoma. Size of GTV is an independent prognostic factor. Local failure still remains the main reason of treatment failures. The authors declare no conflicts of interest in preparing this article.« less

Symptomatic cervical disc disease (SCDD) is a common degenerative disease, and Discover artificial cervical disc, a new-generation nonconstrained artificial disk, has been developed and performed gradually to treat it. We performed this meta-analysis to compare the efficacy and safety between Discover cervical disc arthroplasty (DCDA) and anterior cervical discectomy and fusion (ACDF) for SCDD. An exhaustive literature search of PubMed, EMBASE, and the Cochrane Library was conducted to identify randomized controlled trials that compared DCDA with ACDF for patients suffering SCDD. A random-effect model was used. Results were reported as standardized mean difference or risk ratio with 95% confidence interval. Of 33 articles identified, six studies were included. Compared with ACDF, DCDA demonstrated shorter operation time (P < 0.0001), and better range of motion (ROM) at the operative level (P < 0.00001). But no significant differences were observed in blood loss, neck disability index (NDI) scores, neck and arm pain scores, Japanese orthopaedic association (JOA) scores, secondary surgery procedures and adverse events (P > 0.05). Subgroup analyses did not demonstrated significant differences. In conclusion, DCDA presented shorter operation time, and better ROM at the operative level. However, no significant differences were observed in blood loss, NDI scores, neck and arm pain scores, JOA scores, secondary surgery procedures and adverse events between the two groups. Additionally, more studies of high quality with mid- to long-term follow-up are required in future.

To understand better the current regional situation and public health response to cervical cancer and female breast cancer in the Americas. Data on cervical cancer and female breast cancers in 33 countries, for the period from 2000 to the last year with available data, were extracted from the Pan American Health Organization (PAHO) Regional Mortality Database and analysed. Changes in mortality rates over the study period - in all countries except those with small populations and large fluctuations in time-series mortality data - were calculated using Poisson regression models. Information from the PAHO Country Capacity Survey on noncommunicable diseases was also analysed. The Bahamas, Trinidad and Tobago and Uruguay showed relatively high rates of death from breast cancer, whereas the three highest rates of death from cervical cancer were observed in El Salvador, Nicaragua and Paraguay. Several countries - particularly Paraguay and Venezuela - have high rates of death from both types of cancer. Although mortality from cervical cancer has generally been decreasing in the Americas, decreases in mortality from breast cancer have only been observed in a few countries in the Region of the Americas. All but one of the 25 countries in the Americas included in the PAHO Country Capacity Survey reported having public health services for the screening and treatment of breast and cervical cancers. Most countries in the Americas have the public health capacity needed to screen for - and treat - breast and cervical cancers and, therefore, the potential to reduce the burden posed by these cancers.

Interleukin-8 (IL-8) serves an important function in chronic inflammation and cancer development; however, the underlying molecular mechanism(s) of IL-8 in uterine cervical cancer remains unclear. The present study investigated whether IL-8 and its receptors [IL-8 receptor (IL-8R)A and IL-8RB] contributed to the proliferative and migratory abilities of HeLa cervical cancer cells, and also investigated the potential underlying molecular mechanisms. Results demonstrated that IL-8 and its receptors were detected in HeLa cells, and levels of IL-8RA were significantly increased compared with those of IL-8RB. Furthermore, the level of IL-8 in cervical cancer tissues was significantly increased compared with that in normal uterine cervical tissues, and migratory and proliferative efficiencies of HeLa cells treated with exogenous IL-8 were increased, compared with untreated HeLa cells. In addition, exogenous IL-8 was able to downregulate endocytic adaptor protein (NUMB), and upregulate IL-8RA, IL-8RB and extracellular signal-regulated protein kinases (ERKs) expression levels in HeLa cells. Results suggest that IL-8 and its receptors were associated with the tumorigenesis of uterine cervical cancer, and exogenous IL-8 promotes the carcinogenic potential of HeLa cells by increasing the expression levels of IL-8RA, IL-8RB and ERK, and decreasing the expression level of NUMB.

To evaluate cytologic diagnoses of dysbacteriosis and Gardnerella infection and to obtain insight into the diagnostic problems of Gardnerella. One hundred randomly selected samples of each of 3 diagnostic series were rescreened by 2 pathologists, resulting in 2 rescreening diagnoses and a consensus diagnosis. A smear was considered unequivocal when the original O code and the O code of the consensus diagnoses were equal and discordant when the flora diagnoses of the 2 pathologists differed. Discordance was highest in the dysbacteriotic series (20%) and lowest in the healthy group (4%). Unequivocal diagnoses were established in 65% of the dysbacteriotic smears, 80% of the Gardnerella smears and 93% of the healthy smears. Misclassification of Gardnerella occurred in the presence of clusters of bacteria mixed with spermatozoa. Blue mountain cells in Gardnerella infection can be identified unequivocally in cervical smears. Because of the clinical importance of treating Gardnerella, such advantageous spin-offs of cervical screening should be exploited.

Persistent neck pain is a common problem after surgery of the cervical spine. No therapy recommendation exists for these patients. The objective of this study was to determine if a therapeutic medial branch block is a rational treatment for patients with postoperative neck pain after cervical spine operations. Retrospective practice audit. Review of charts of all patients who underwent cervical spine operations for degenerative reasons during a time period of 3 years. Patients with persistent postsurgical pain were treated with therapeutic medial branch blocks (local anesthetic and steroid). A positive treatment response was defined if at least 80% reduction of pain could be achieved or if the patient was sufficiently satisfied with the relief. All patients with a minimum follow up time of 6 months were included. Of the 312 operations performed, 128 were artificial disc operations, 125 were stand alone cages, and 59 were fusions with cage and plate. Persistent neck pain occurred in 33.3% of the patients. There was no difference between the patients with neck pain and the whole group of patients. More than half of the patients with neck pain--52.9%--were treated successfully with therapeutic medial branch blocks. Since no further treatment was necessary, the initial treatment was considered successful. Nearly a third--32.2%--of the patients were initially treated successfully, but their pain recurred and further diagnostics and treatments were necessary. In this group of patients, significantly more with double level operations were found (P = 0.003). Patients not responding to the medial branch block were 14.9%. This audit is retrospective and observational, and therefore does not represent a high level of evidence. However, to our knowledge, since this information has not been previously reported and no recommendation for the treatment of post-operative zygapophysial joint pain exists, it appears to be the best available research upon which to recommend treatment and to plan higher quality studies. For persistent postsurgical neck pain only limited therapy recommendations exist. This study suggests treating these patients in a first instance with therapeutic medial branch blocks. The success rate is 52.9 %.

Upper cervical instability is common in many skeletal dysplasias, and surgical treatment can be difficult because of small, fragile osseous elements. In this study of children with skeletal dysplasia and upper cervical instability, we compared fusion rates and complications between (1) patients treated with no instrumentation or with wiring techniques and (2) those who underwent rigid cervical spine instrumentation. We also sought to characterize the presentation and common parameters of upper cervical instability in this population. A multicenter study identified twenty-eight children with skeletal dysplasia who underwent surgery from 2000 through 2011 for C1-C2 instability and were followed for a minimum of two years. Fourteen children were treated with no instrumentation or with instrumentation with wires or cables (nonrigid-fixation group) and fourteen were treated with screws (or hooks) and rods (rigid-fixation group). All patients received autograft, and twenty (twelve in the nonrigid group and eight in the rigid group) were treated with a halo-body jacket. Fourteen children had C1-C2 fusion, and fourteen had occipitocervical fusion. Eleven (39%) underwent spinal cord decompression. The nonunion rate was significantly higher in the nonrigid-fixation group (six of fourteen) than in the rigid-fixation group (zero of fourteen; p = 0.0057). Complications, including nonunion, occurred in nine patients in the nonrigid group and one patient in the rigid group. However, two of the complications in the nonrigid-fixation group were vertebral artery bleeding episodes that actually occurred during an attempt at rigid fixation (the fixation was subsequently done with wiring). No new neurologic deficits were observed. Five of the seven children with a preoperative neurologic deficit showed at least partial recovery, with significant improvement in the Japanese Orthopaedic Association upper-extremity score (p = 0.047). The nonunion rate is relatively high after patients undergo spinal fusion for C1-C2 instability with nonrigid instrumentation, even if a halo-body jacket is applied. Rigid fixation with screws and rods improves fusion rates. Copyright © 2015 by The Journal of Bone and Joint Surgery, Incorporated.

Most previous studies of the use of cervical pessaries were either retrospective or case controlled and their results showed that this intervention might be a preventive strategy for women at risk of preterm birth; no randomised controlled trials have been undertaken. We therefore undertook a randomised, controlled trial to investigate whether the insertion of a cervical pessary in women with a short cervix identified by use of routine transvaginal scanning at 20-23 weeks of gestation reduces the rate of early preterm delivery. The Pesario Cervical para Evitar Prematuridad (PECEP) trial was undertaken in five hospitals in Spain. Pregnant women (aged 18-43 years) with a cervical length of 25 mm or less were randomly assigned according to a computer-generated allocation sequence by use of central telephone in a 1:1 ratio to the cervical pessary or expectant management (without a cervical pessary) group. Because of the nature of the intervention, this study was not masked. The primary outcome was spontaneous delivery before 34 weeks of gestation. Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00706264. 385 pregnant women with a short cervix were assigned to the pessary (n=192) and expectant management groups (n=193), and 190 were analysed in each group. Spontaneous delivery before 34 weeks of gestation was significantly less frequent in the pessary group than in the expectant management group (12 [6%] vs 51 [27%], odds ratio 0·18, 95% CI 0·08-0·37; p<0·0001). No serious adverse effects associated with the use of a cervical pessary were reported. Cervical pessary use could prevent preterm birth in a population of appropriately selected at-risk women previously screened for cervical length assessment at the midtrimester scan.

Cost-effectiveness analysis with decision analysis and meta-analysis. To determine the relative cost-effectiveness of anterior cervical discectomy with fusion (with autograft, allograft, or spacers), anterior cervical discectomy without fusion (ACD), and cervical disc replacement (CDR) for the treatment of 1-level cervical disc disease. There is debate as to the optimal anterior surgical strategy to treat single-level cervical disc disease. Surgical strategies include 3 techniques of anterior cervical discectomy with fusion (autograft, allograft, or spacer-assisted fusion), ACD, and CDR. Several controlled trials have compared these treatments but have yielded mixed results. Decision analysis provides a structure for making a quantitative comparison of the costs and outcomes of each treatment. A literature search was performed and yielded 156 case series that fulfilled our search criteria describing nearly 17,000 cases. Data were abstracted from these publications and pooled meta-analytically to estimate the incidence of various outcomes, including index-level and adjacent-level reoperation. A decision analytic model calculated the expected costs in US dollars and outcomes in quality-adjusted life years for a typical adult patient with 1-level cervical radiculopathy subjected to each of the 5 approaches. At 5 years postoperatively, patients who had undergone ACD alone had significantly (P < 0.001) more quality-adjusted life years (4.885 ± 0.041) than those receiving other treatments. Patients with ACD also exhibited highly significant (P < 0.001) differences in costs, incurring the lowest societal costs ($16,558 ± $539). Follow-up data were inadequate for comparison beyond 5 years. The results of our decision analytic model indicate advantages for ACD, both in effectiveness and costs, over other strategies. Thus, ACD is a cost-effective alternative to anterior cervical discectomy with fusion and CDR in patients with single-level cervical disc disease. Definitive conclusions about degenerative changes after ACD and adjacent-level disease after CDR await longer follow-up. 4.

The rat parvovirus H-1PV has oncolytic and tumour-suppressive properties potentially exploitable in cancer therapy. This possibility is being explored and results are encouraging, but it is necessary to improve the oncotoxicity of the virus. Here we show that this can be achieved by co-treating cancer cells with H-1PV and histone deacetylase inhibitors (HDACIs) such as valproic acid (VPA). We demonstrate that these agents act synergistically to kill a range of human cervical carcinoma and pancreatic carcinoma cell lines by inducing oxidative stress, DNA damage and apoptosis. Strikingly, in rat and mouse xenograft models, H-1PV/VPA co-treatment strongly inhibits tumour growth promoting complete tumour remission in all co-treated animals. At the molecular level, we found acetylation of the parvovirus nonstructural protein NS1 at residues K85 and K257 to modulate NS1-mediated transcription and cytotoxicity, both of which are enhanced by VPA treatment. These results warrant clinical evaluation of H-1PV/VPA co-treatment against cervical and pancreatic ductal carcinomas. © 2013 The Authors. Published by John Wiley and Sons, Ltd on behalf of EMBO.

Cervical total disc replacement (TDR) is an increasingly accepted procedure for the treatment of symptomatic cervical degenerative disc disease. Multiple Level I evidence clinical trials have established cervical TDR to be a safe and effective procedure in the short-term. The objective of this study is to provide a long-term assessment of TDR versus anterior discectomy and fusion for the treatment of one- and two-level disc disease. This study was a continuation of a prospective, multicenter, randomized, US FDA IDE clinical trial comparing cervical TDR with the Mobi-C © Cervical Disc versus ACDF through 7 years follow-up. Inclusion criteria included a diagnosis of symptomatic cervical degenerative disc disease at one or two cervical levels. TDR patients were treated using a Mobi-C © artificial disc (Zimmer Biomet, Austin TX, USA). ACDF with allograft and anterior plate was used as a control treatment. Outcome measures were collected preoperatively and postoperatively at 6 weeks, at 3, 6, 12, 18 months, annually through 60 months, and at 84 months. Measured outcomes included Overall success, Neck Disability Index (NDI), VAS neck and arm pain, segmental range of motion (ROM), patient satisfaction, SF-12 MCS/PCS, major complications, and subsequent surgery rate. The primary endpoint was an FDA composite definition of success comprising clinical improvement and an absence of major complications and secondary surgery events. A total of 599 patients were enrolled and treated, with 164 treated with one-level TDR, 225 treated with two-level TDR, 81 treated with one-level ACDF, and 105 treated with two-level ACDF. At seven years, follow-up rates ranged from 73.5% to 84.4% (overall 80.2%).The overall success rates of two level TDR and ACDF patients were 60.8% and 34.2%, respectively (p<0.0001). The overall success rates of one level TDR and ACDF patients were 55.2% and 50%, respectively (p>0.05). Both the single and two level TDR and ACDF groups showed significant improvement from baseline NDI scores, VAS neck and arm pain scores, and SF-12 MCS/PCS scores (p<0.0001). In the single level cohort, there was an increased percentage of TDR patients who reported themselves as "very satisfied" (TDR 90.9% vs ACDF 77.8%; p= 0.028). There was a lower rate of adjacent level secondary surgery in the single level TDR patients (3.7%) versus the ACDF patients (13.6%; p = 0.007).In the two level TDR group, the NDI success rate was significantly greater in the TDR group (TDR: 79.0% vs. ACDF: 58.0%; p=0.001). There was significantly more improvement in NDI change score at 7 years in the TDR patients versus ACDF. The TDR group had a significantly higher rate of patients who were "very satisfied" with their treatment compared to the ACDF group (TDR: 85.9% vs. ACDF: 73.9%). The rate of subsequent surgery at the index level was significantly lower in the TDR group compared to the ACDF group (TDR: 4.4% vs. ACDF: 16.2%; p=0.001). The rate of adjacent level secondary surgery was significantly lower in the two level TDR (4.4%) patients compared to the ACDF (11.3%; p=0.03) patients. In both single and two level cohorts, the percentage of patients with worse NDI (2.5%-3.8% of two level surgeries and 1.2%-2.5% of single level surgeries) or worse neck pain (5%-6.8% of the two level surgeries and 1.3% - 3.8% of the single level surgeries) was strikingly low in both groups but trended lower in the TDR patients. At seven years, the composite success analysis demonstrated clinical superiority of two level TDR over ACDF and non-inferiority of single level TDR versus ACDF. There were lower rates of secondary surgery and higher adjacent level disc survivorship in both groups. Both surgeries were remarkably effective in alleviating pain relative to baseline and the rate of patients with worse disability or neck pain was surprisingly low. Overall, greater than 95% of patients (from both groups) who underwent TDR and 88% of patients who underwent ACDF were "very satisfied" at seven years. The differences in clinical effectiveness of TDR versus ACDF becomes more apparent as treatment increases from one to two levels, indicating a significant benefit for TDR over ACDF for two-level procedures. The Mobi-C Clinical Trial (ClinicalTrials.gov registration number: NCT00389597) was conducted at 24 sites in the US and was approved by the Institutional Review Board, Research Ethics Committee, or local equivalent of each participating site. 1.

Case report. We present a case of myositis ossificans (MO) of the upper cervical spine in a young child. The literature is reviewed with the classification, etiology, and treatment of MO discussed. Calcification of joint capsule, muscle, cartilage, and ligaments is a well-known phenomenon and is known as myositis ossificans. It is very rarely seen in the head and neck, with no reports of MO of the soft tissues surrounding the first 2 cervical vertebrae. An 8-year-old boy presented with severe neck pain after a fall. He had had a similar neck injury 4 years before, but made a full recovery. Radiographs showed a large ossified lesion between the posterior elements of C1 and C2. After further imaging, a diagnosis of MO was made. The child was treated with simple analgesia and observation. With no evidence of neurologic compromise and minimal symptoms, there was no indication for surgical intervention. Although rare, MO should be suspected as one of the possible causes of persistent pain following cervical spine injury in children. We would advise a low threshold for cervical spine imaging in the child presenting with persistent neck pain and stiffness, even years after injury.

The authors present the results of analysis of combined physiobalneotherapy in the patients with neurological manifestations of degenerative lesions in the cervical spine with special reference to the clinical form of the disease. The use of unified criteria for the assessment of cervico-brachial pain syndrome and clinico-neuropsychological status of the patients in conjunction with auxiliary research techniques made it possible to demonstrate the high efficacy of the treatment using low-frequency pulse therapy supplemented by the application of radon baths. The best therapeutic effect was achieved in a group of patients presenting with cervico-brachial syndrome treated during the periods of exacerbation of cervical spine osteochondrosis. A less pronounced positive effect was documented in the group having the recurrent clinical course of cervico-brachial pain syndrome due to degenerative and dystrophic lesions in the cervical spine and diskopathy. The difference between the responses of the two groups of patients can be accounted for not only by the severity of degenerative lesions in the cervical spine but also by the changes in their psychoemotional sphere.

To compare the short-term efficacy of anterior cervical discectomy and fusion(ACDF) with traditional nail plate system and Zero-profile device in the treatment of cervical spondylotic myelopathy(CSM). The clinical data of 45 patients with CSM treated from July 2014 to August 2015 was retrospectively analyzed. There were 23 males and 22 females with an average age of 53.7 years old(range, 32 to 71 years old). The course of disease was 5 months to 2 years. All the patients were treated with ACDF with 24 cases by traditional nail plate system fixation(group A) and 21 cases by Zero-P system fixation(group B). Operation time and intraoperative bleeding were compared between two groups. Neurological function and cervical pain were evaluated by Japanese Orthopaedic Association scores (JOA) and visual analogue scale (VAS), respectively. Cervical curvature(Cobb angle) change and intervertebral fusion were evaluated by X-rays and CT. And associated complications were analyzed in two groups. All the patients were followed up for 12 to 16 months with an average of 14 months. Operation time of group A and B was(87.6±23.2) min and (62.7±17.3) min respectively, and the difference was significant between two groups; and intraoperative bleeding was (80.2±36.8) ml and (78.4±29.6) ml respectively, and the difference was not significant. At final follow-up, JOA and VAS of all patients were obvious improved, but there was no significant difference between two groups. Preoperative Cobb angle in group A and B was (8.7±4.3) ° and (8.6±4.2) ° respectively, and the difference was significant. The Cobb angle at final follow-up was (14.5±6.4) ° and (17.4±8.6) ° respectively, and the difference between two groups was significant. The incidence of dysphagia in group A and B were 29.17% and 9.52% respectively, and there was significant difference between two groups. All intervertebral spaces got fusion at final follow-up. No tracheo-asophageal injury and recurrent laryngeal nerve damage or other complications were found. No fusional migration, subsidence, loosening, breakage, etc. were found. The clinical comparison of Zero-P interbody fixation system and cervical plate internal fixation for the treatment of cervical spondylosis was quite fair, but Zero-P showed a better therapeutic effect with improvement of life quality.

Reoperation After Cervical Disc Arthroplasty Versus Anterior Cervical Discectomy and Fusion: A Meta-analysis.

Anterior cervical discectomy and fusion is a standard surgical treatment for cervical radiculopathy and myelopathy, but reoperations sometimes are performed to treat complications of fusion such as pseudarthrosis and adjacent-segment degeneration. A cervical disc arthroplasty is designed to preserve motion and avoid the shortcomings of fusion. Available evidence suggests that a cervical disc arthroplasty can provide pain relief and functional improvements similar or superior to an anterior cervical discectomy and fusion. However, there is controversy regarding whether a cervical disc arthroplasty can reduce the frequency of reoperations. We performed a meta-analysis of randomized controlled trials (RCTs) to compare cervical disc arthroplasty with anterior cervical discectomy and fusion regarding (1) the overall frequency of reoperation at the index and adjacent levels; (2) the frequency of reoperation at the index level; and (3) the frequency of reoperation at the adjacent levels. PubMed, EMBASE, and the Cochrane Register of Controlled Trials databases were searched to identify RCTs comparing cervical disc arthroplasty with anterior cervical discectomy and fusion and reporting the frequency of reoperation. We also manually searched the reference lists of articles and reviews for possible relevant studies. Twelve RCTs with a total of 3234 randomized patients were included. Eight types of disc prostheses were used in the included studies. In the anterior cervical discectomy and fusion group, autograft was used in one study and allograft in 11 studies. Nine of 12 studies were industry sponsored. Pooled risk ratio (RR) and associated 95% CI were calculated for the frequency of reoperation using random-effects or fixed-effects models depending on the heterogeneity of the included studies. A funnel plot suggested the possible presence of publication bias in the available pool of studies; that is, the shape of the plot suggests that smaller negative or no-difference studies may have been performed but have not been published, and so were not identified and included in this meta-analysis. The overall frequency of reoperation at the index and adjacent levels was lower in the cervical disc arthroplasty group (6%; 108/1762) than in the anterior cervical discectomy and fusion group (12%; 171/1472) (RR, 0.54; 95% CI, 0.36-0.80; p = 0.002). Subgroup analyses were performed according to secondary surgical level. Compared with anterior cervical discectomy and fusion, cervical disc arthroplasty was associated with fewer reoperations at the index level (RR, 0.50; 95% CI, 0.37-0.68; p < 0.001) and adjacent levels (RR, 0.52; 95% CI, 0.37-0.74; p < 0.001). Cervical disc arthroplasty is associated with fewer reoperations than anterior cervical discectomy and fusion, indicating that it is a safe and effective alternative to fusion for cervical radiculopathy and myelopathy. However, because of some limitations, these findings should be interpreted with caution. Additional studies are needed. Level I, therapeutic study.

Fractures of the axis (C2) are the most common cervical spinal injuries in the elderly population. Several authors have reported improved survival among elderly patients with C2 fractures when treated surgically. We aimed to analyze whether surgery improves survival of elderly with C2 fractures. An observational population-based longitudinal multi-registry study was carried out. Swedish Patient Registry 1997 to 2014 and Swedish Cause of Death Registry 1997 to 2014 served as source of patient sample. Survival after C2 fracture according to non-surgical and surgical treatment was the outcome measure. We included all patients treated for the primary diagnosis of C2 fracture (10th revision of the International Statistical Classification of Diseases and Related Health Problems or ICD-10: S12.1) at an age ≥70 years and receiving treatment at a health-care facility. Non-surgical treatment comprises cervical collar or halo-vest treatment. Surgical treatment was identified in the Swedish patient registry extract using the Swedish classification of procedural codes. Survival was determined using the Kaplan-Meier method. Comorbidity was determined using the Charlson Comorbidity Index. Of the included 3,375 elderly patients with C2 fractures (43% men, aged 83±7 years), 22% were treated surgically. Surgical treatment was assigned based on age, gender, and year of treatment. The 1-year survival of 2,618 non-surgically treated patients was 72% (n=1,856), and 81% (n=614) for the 757 surgically treated (p<.001, relative risk reduction=11%). Adjusted for age, gender, comorbidity, and year of injury, surgically treated patients had greater survival than non-surgically treated patients (hazard ratio=0.88, 95% confidence interval: 0.79-0.97). Among those above 88 years of age (95% confidence interval: 85-92), surgical treatment lost its effect on survival. Despite the frailty of elderly patients, the morbidity of cervical external immobilization with a rigid collar seemingly weighs greater than surgical morbidity, even in octogenarians. For those above 88 years of age, non-surgical treatment should be primarily attempted. Copyright © 2018 The Author(s). Published by Elsevier Inc. All rights reserved.

Abstract The present study aimed to explore surgical treatments and assess the effects based on the features of cervical spine fracture in patients with ankylosing spondylitis (AS) and to summarize the experiences in perioperative management. Retrospective analysis was performed in 25 AS patients with cervical spine fracture treated in our hospital from January 2011 to December 2013. The patients were divided according to fracture segments, including 4 cases at C4 to C5, 8 cases at C5 to C6, and 13 cases at C6 to C7. Among them, 12 belonged to I type, 5 to II type, and 8 to III type based on the improved classification method for AS cervical spine fracture. The Subaxial Cervical Spine Injury Classification score for these patients was 7.2 ± 1.3, and the assessment of their neurological function states showed 6 patients (24%) were in American Spinal Injury Association (ASIA) A grade, 1 (4%) in ASIA B grade, 3 (12%) in ASIA C grade, 12 (48%) in ASIA D grade, and 3 (12%) in ASIA E grade. Surgical methods contained simple anterior approach alone, posterior approach alone, and combined posterior–anterior or anterior–posterior approach. The average duration of patients’ hospital stay was 38.6 ± 37.6, and the first surgical methods were as follows: anterior approach alone on 6 cases, posterior surgery alone on 9 cases, and combined posterior–anterior or anterior–posterior approach on 10 patients. The median segments of fixation and fusion were 4.1 ± 1.4 sections. Thirteen patients developed complications. During 2 to 36 months of postoperative follow-up, 1 patient died of respiratory failure caused by pulmonary infections 2 months after leaving hospital. At the end of the follow-up, bone graft fusion was achieved in the rest of patients, and obvious looseness or migration of internal fixation was not observed. In addition, the preoperative neurological injury in 12 patients (54.5%) was also alleviated in different levels. AS cervical spine fracture, an unstable fracture, should be treated with operation, and satisfactory effects will be achieved after the individualized surgical treatment according to the improved classification method for AS cervical spine fracture.

To assess skeletal and dental changes in patients successfully treated with the Forsus appliance based on cervical vertebral maturation status. Forty-seven Class II patients, successfully treated with the Forsus appliance, were divided into peak and postpeak growth groups determined immediately prior to Forsus placement. The mean (SD) ages of the peak and postpeak groups were 13.4 (1.0) and 14.1 (1.3) years, respectively. Superimpositions of initial, Forsus placement, Forsus removal, and final cephalometric radiographs were completed, allowing the measurement of changes during three treatment phases. There were no significant differences between groups during treatment phase 1 (alignment/leveling), with both groups demonstrating a worsening of the Class II molar relationship. However, during treatment phase 2 (Class II correction), patients within the peak group demonstrated significantly higher mean apical base, mandibular and molar changes, and an increased rate of change compared with those in the postpeak group. No significant differences were observed during treatment phase 3 (detail/finishing). Following an initial worsening of the Class II molar relationship as a result of straight-wire appliance effects, Forsus appliance treatment initiated during cervical vertebral maturation status (CS) 3-4 elicits more effective and efficient correction of Class II molar relationships than when initiated during CS 5-6. Data support that these effects are due mainly to maxillary skeletal and dentoalveolar restraint during a period of more rapid mandibular growth.

Cervical cancer is preventable but continues to cause the deaths of more than 270,000 women worldwide each year, most of them in developing countries where programs to detect and treat precancerous lesions are not affordable or available. Studies have demonstrated that screening by visual inspection of the cervix using acetic acid (VIA) is a simple, affordable, and sensitive test that can identify precancerous changes of the cervix so that treatment such as cryotherapy can be provided. Government partners implemented screening and treatment using VIA and cryotherapy at demonstration sites in Peru, Uganda, and Vietnam. Evaluations were conducted in the three countries to explore the barriers and facilitating factors for the use of services and for incorporation of screen-and-treat programs using VIA and cryotherapy into routine services. Results showed that use of VIA and cryotherapy in these settings is a feasible approach to providing cervical cancer prevention services. Activities that can help ensure successful programs include mobilizing and educating communities, organizing services to meet women's schedules and needs, and strengthening systems to track clients for follow-up. Sustainability also depends on having an adequate number of trained providers and reducing staff turnover. Although some challenges were found across all sites, others varied from country to country, suggesting that careful assessments before beginning new secondary prevention programs will optimize the probability of success.

Prolonged accumulation of misfolded or unfolded proteins caused by cellular stress, including oxidative stress, induces endoplasmic reticulum stress, which then activates an unfolded protein response (UPR). ER stress is usually maintained at higher levels in cancer cells as compared to normal cells due to altered metabolism in cancer. Here, we investigated whether curcumin is ER stress-mediated apoptosis in cervical cancer cells, and ROS increased by curcumin are involved in the process as an upstream contributor. Curcumin inhibited proliferation of cervical cancer cells (C33A, CaSki, HeLa, and ME180) and induced apoptotic cell death. Curcumin activated ER-resident UPR sensors, such as PERK, IRE-1α, and ATF6, and their downstream-signaling proteins in cervical cancer cells, but not in normal epithelial cells and peripheral blood mononuclear cells (PBMCs). CHOP, a key factor involved in ER stress-mediated apoptosis, was also activated by curcumin. CHOP decreased the ratio of anti-apoptotic protein Bcl-2 to pro-apoptotic protein Bax expression, and subsequently increased the apoptotic population of cervical cancer cells. Furthermore, curcumin elevated levels of intracellular reactive oxygen species (ROS) in cervical cancer cells, but not in normal epithelial cells. Scavenging ROS resulted in inhibition of ER stress and partially restored cell viability in curcumin-treated cancer cells. Collectively, these observations show that curcumin promotes ER stress-mediated apoptosis in cervical cancer cells through increase of cell type-specific ROS generation. Therefore, modulation of these differential responses to curcumin between normal and cervical cancer cells could be an effective therapeutic strategy without adverse effects on normal cells. © 2015 Wiley Periodicals, Inc.

The colony-forming ability of cervical cancer is affected by many factors. Oct4, an important transcription factor, is highly expressed in several tumors and promotes the colony-forming ability of cancer cells. Thus, it is considered a potential target for the treatment of cancer. However, we know little about the expression level of Oct4 and its epigenetic regulatory mechanism in cervical cancer cells. In this study, we are the first to observe that human papillomavirus (HPV)-positive cervical cancer cell lines (HeLa, Caski) have a stronger colony-forming ability than HPV-negative cervical cancer cell lines (C-33A). Moreover, the expression level of Oct4 in both HeLa and Caski cells was also higher than that in C-33A cells. We then confirmed that there was a negative correlation between the expression of Oct4 and DNMT3A in these three types of cervical cancer cells, whereas DNA methyltransferase 1 and 3B had no differences among the cell lines. However, after DNA methylation in both key regulatory regions of the Oct4 gene and the genomic levels were analyzed, we found that DNA methyltransferase 3A could neither regulate the expression of Oct4 nor affect the whole level of genomic DNA methylation. These results suggest three points: (1) Oct4 might be treated as a new target for the treatment of cervical cancer, (2) we could not inhibit the expression of Oct4 by DNA demethylation, and (3) HPV virus might initiate cervical carcinogenesis by upregulation of Oct4 expression.

A medico-legal review of cases involving quadriplegia following cervical spine surgery: Is there an argument for a no-fault compensation system?

To determine whether patients who become quadriplegic following cervical spine surgery are adequately compensated by our present medico-legal system. The outcomes of malpractice suits obtained from Verdict Search (East Islip, NY, USA), a medico-legal journal, were evaluated over a 20-year period. Although the present malpractice system generously rewards many quadriplegic patients with substantial settlements/ Plaintiffs' verdicts, a subset receive lesser reimbursements (verdicts/settlements], while others with defense verdicts receive no compensatory damages. Utilizing Verdict Search, 54 cases involving quadriplegia following cervical spine surgery were reviewed for a 20-year interval (1988-2008). The reason(s) for the suit, the defendants, the legal outcome, and the time to outcome were identified. Operations included 25 anterior cervical procedures, 22 posterior cervical operations, 1 circumferential cervical procedure, and 6 cases in which the cervical operations were not defined. The four most prominent legal allegations for suits included negligent surgery (47 cases), lack of informed consent (23 cases), failure to diagnose/treat (33 cases), and failure to brace (15 cases). Forty-four of the 54 suits included spine surgeons. There were 19 Plaintiffs' verdicts (average US $5.9 million, range US $540,000-US $18.4 million), and 20 settlements (average US $2.8 million, range US $66,500-US $12.0 million). Fifteen quadriplegic patients with defense verdicts received no compensatory damages. The average time to verdicts/settlements was 4.3 years. For 54 patients who were quadriplegic following cervical spine surgery, 15 (28%) with defense verdicts received no compensatory damages. Under a No-Fault system, quadriplegic patients would qualify for a "reasonable" level of compensation over a "shorter" time frame.

Objective A Zero-profile device is a cervical stand-alone cage with integrated segmental fixation device. We characteristically evaluated the radiological changes as well as clinical outcomes in the application of Zero-profile devices compared with stand-alone cages and anterior cervical plates with iliac bone grafts for the cervical disease. Methods Retrospectively, total 60 patients at least more than one year follow-up were enrolled. Twenty patients were treated with Zero-profile devices (Group A), twenty patients with stand-alone cages (Group B) and twenty patients with anterior cervical plates and iliac bone grafts (Group C) for a single level cervical disease. The clinical outcomes were evaluated by Odom's criteria and Bazaz-Yoo dysphagia index. The radiologic parameters were by subsidence and the changes of the midpoint interbody height (IBH), the segmental kyphotic angle (SKA), the overall kyphotic angle (OKA) in index level. Results Although there was no significant clinical difference according to the Odom's criteria among them(p=0.766), post-operative dysphagia was significantly decreased in the Group A and B compared with the Group C (p=0.04). From the immediate postoperative to the last follow-up time, the mean change of IBH decrement and SKA increment were significant in the Group B compared with the Group A (p=0.025, p=0.033) and the Group C (p=0.001, p=0.000). The subsidence rate was not significant among all groups (p=0.338). Conclusion This Zero-profile device is a valuable alternative to the anterior cervical discectomy and fusion with a low incidence of postoperative dysphagia and without segmental kyphotic change.

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.

The aim of this report is to describe the potential clinical utility of tracer [F-18]-Fluorodeoxyglucose (FDG) uptake, quantitated as a standardized uptake value (SUV) by positron emission tomography (PET), to evaluate treatment response to neoadjuvant chemotherapy (NAC) in advanced uterine cervical cancer. We briefly describe the clinical courses of three women with advanced cervical cancer who were treated with neoadjuvant chemotherapy (NAC) prior to radical hysterectomy and who were analyzed for correlation with the decrease in tumor volume by magnetic resonance imaging (MRI), in SUV by FDG-PET, and by histologic response. In these individuals, tumor volume and SUV were decreased by NAC. The decrease in SUV by FDG-PET was better correlated to histologic response for NAC than MRI was in advanced cervical cancer. Measurement of SUV by FDG-PET has clinical utility in evaluating treatment response for NAC in advanced cervical cancer. Although work in this field is still in the early stages, this report demonstrates that SUV by FDG-PET has the potential to become the new standard for monitoring the treatment response of NAC in cervical cancer. This monitoring approach must be proven in a larger number of patients for both primary and secondary lesions and should be further explored in another gynecologic cancer.

Estrogen and its nuclear receptor, estrogen receptor α, are necessary cofactors in the initiation and multistage progression of carcinogenesis in the K14E6/E7 transgenic mouse model of human papillomavirus–associated cervical cancer. Recently, our laboratory reported that raloxifene, a selective estrogen receptor modulator, promoted regression of high-grade dysplasia and cancer that arose in the cervix of K14E6/E7 transgenic mice treated long-term with estrogen. Herein, we evaluated the recurrence of cervical cancer after raloxifene therapy in our preclinical model of human papillomavirus–associated cervical carcinogenesis. We observed recurrence of cervical cancer in mice re-exposed to estrogen after raloxifene treatment, despite evidence suggesting the antagonistic effects of raloxifene persisted in the reproductive tract after treatment had ceased. We also observed recurrence of neoplastic disease in mice that were not retreated with exogenous estrogen, although the severity of disease was less. Recurrent neoplastic disease and cancers retained functional estrogen receptor α and responded to retreatment with raloxifene. Moreover, continuous treatment of mice with raloxifene prevented the emergence of recurrent disease seen in mice in which raloxifene was discontinued. These data suggest that cervical cancer cells are not completely eradicated by raloxifene and rapidly expand if raloxifene treatment is ceased. These findings indicate that a prolonged treatment period with raloxifene might be required to prevent recurrence of neoplastic disease and lower reproductive tract cancers. PMID:24418098

Case report: absent C6 cervical pedicle in a collegiate football player.

Congenital absence of a cervical pedicle is a rare clinical finding with only 70 reported cases in the literature from 1946 until present. The congenitally absent pedicle has clinical importance owing to the frequency of misdiagnosis and inappropriate invasive treatments. We present the case of a 21-year-old college football player who experienced neck and shoulder pain after violent twisting of his neck by the face mask. The player walked off the field under his own power. He was sent to the locker room, where he underwent right shoulder and cervical spine radiographs. Initial review of the radiographs raised concern for a jumped right C6 facet. The patient then underwent CT and MRI of the cervical spine, confirming the diagnosis of an absent cervical pedicle. He was treated nonoperatively for a short time and completed the season. He had no symptoms at last followup at 8 months. The most frequent location of the absent cervical pedicle is at the C6 level, and the next most common is at the C5 level. Neural compression or instability is uncommon and nonsurgical treatment is the mainstay of treatment. Misdiagnosis can lead to inappropriate treatment such as halo or tong application with traction, which occurred in seven of 57 cases in one series, and exploratory surgery, which occurred in four of 57 cases.

Human papilloma virus (HPV) is one of the main risk factors associated with the development of cervical cancer and its precursor lesions. It has been reported that HPV16 and 18 types cover approximately 70% of cervical cancer worldwide; however, significant variation in percentages of HPV infections could be related to specific populations. Purified DNA of 67 cervical samples were analyzed by Linear Array® HPV genotyping kit. These analyzed samples correspond to 19 cervical tumors, 15 high-grade squamous intraepithelial lesions, 20 low-grade squamous intraepithelial lesions, and 13 cervical samples without injury were studied, all of them previously diagnosed. In general, 16 different HPV types were found with differences in their frequencies, cervical invasive cancer being the richest in HPV sequences, followed by the low-grade squamous intraepithelial lesions and then high-grade lesions. HPV16 was the most frequently distributed type in neoplastic lesions of the cervix, followed by the HPV52, suggesting viral type variability, probably associated to the geographical region studied. The results could indicate variability in HPV presence in Mexico, underlining the important role for HPV52 among others in the Mexican population. This would also potentially have an impact on the current anti-HPV vaccination schemes. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

The role of prostaglandins E1 and E2, dinoprostone, and misoprostol in cervical ripening and the induction of labor: a mechanistic approach.

PubMed

Bakker, Ronan; Pierce, Stephanie; Myers, Dean

2017-08-01

Prostaglandins play a critical role in cervical ripening by increasing inflammatory mediators in the cervix and inducing cervical remodeling. Prostaglandin E1 (PGE1) and prostaglandin E2 (PGE2) exert different effects on these processes and on myometrial contractility. These mechanistic differences may affect outcomes in women treated with dinoprostone, a formulation identical to endogenous PGE2, compared with misoprostol, a PGE1 analog. The objective of this review is to evaluate existing evidence regarding mechanistic differences between PGE1 and PGE2, and consider the clinical implications of these differences in patients requiring cervical ripening for labor induction. We conducted a critical narrative review of peer-reviewed articles identified using PubMed and other online databases. While both dinoprostone and misoprostol are effective in cervical ripening and labor induction, they differ in their clinical and pharmacological profiles. PGE2 has been shown to stimulate interleukin-8, an inflammatory cytokine that promotes the influx of neutrophils and induces remodeling of the cervical extracellular matrix, and to induce functional progesterone withdrawal. Misoprostol has been shown to elicit a dose-dependent effect on myometrial contractility, which may affect rates of uterine tachysystole in clinical practice. Differences in the mechanism of action between misoprostol and PGE2 may contribute to their variable effects in the cervix and myometrium, and should be considered to optimize outcomes.

Highlights: •miR-196a was overexpressed in cervical cancer tissue compared to normal tissue. •miR-196a expression elevated proliferation and migration of cervical cancer cells. •miR-196a inhibited NTN4 expression by binding 3′-UTR region of NTN4 mRNA. •NTN4 inversely correlated with miR-196a expression in cervical tissue and cell line. •NTN4 expression was low in cervical cancer tissue compared to normal tissue. -- Abstract: Recent research has uncovered tumor-suppressive and oncogenic potential of miR-196a in various tumors. However, the expression and mechanism of its function in cervical cancer remains unclear. In this study, we assess relative expression of miR-196a in cervical premalignant lesions, cervical cancermore » tissues, and four cancer cell lines using quantitative real-time PCR. CaSki and HeLa cells were treated with miR-196a inhibitors, mimics, or pCDNA/miR-196a to investigate the role of miR-196a in cancer cell proliferation and migration. We demonstrated that miR-196a was overexpressed in cervical intraepithelial neoplasia 2–3 and cervical cancer tissue. Moreover, its expression contributes to the proliferation and migration of cervical cancer cells, whereas inhibiting its expression led to a reduction in proliferation and migration. Five candidate targets of miR-196a chosen by computational prediction and Cervical Cancer Gene Database search were measured for their mRNA in both miR-196a-overexpressing and -depleted cancer cells. Only netrin 4 (NTN4) expression displayed an inverse association with miR-196a. Fluorescent reporter assays revealed that miR-196a inhibited NTN4 expression by targeting one binding site in the 3′-untranslated region (3′-UTR) of NTN4 mRNA. Furthermore, qPCR and Western blot assays verified NTN4 expression was downregulated in cervical cancer tissues compared to normal controls, and in vivo mRNA level of NTN4 inversely correlated with miR-196a expression. In summary, our findings provide new insights about the functional role of miR-196a in cervical carcinogenesis and suggested a potential use of miR-196a for clinical diagnosis and as a therapeutic target.« less

Prospective study. To identify proteins with differential expression in the cerebrospinal fluid (CSF) from 15 clinically normal (control) dogs and 15 dogs with cervical spondylomyelopathy (CSM). Canine CSM is a spontaneous, chronic, compressive cervical myelopathy similar to human cervical spondylotic myelopathy. There is a limited knowledge of the molecular mechanisms underlying these conditions. Differentially expressed CSF proteins may contribute with novel information about the disease pathogenesis in both dogs and humans. Protein separation was performed with 2-dimensional electrophoresis. A Student t test was used to detect significant differences between groups (P < 0.05). Three comparisons were made: (1) control versus CSM-affected dogs, (2) control versus non-corticosteroid-treated CSM-affected dogs, and (3) non-corticosteroid-treated CSM-affected versus corticosteroid-treated CSM-affected dogs. Protein spots exhibiting at least a statistically significant 1.25-fold change between groups were selected for subsequent identification with capillary-liquid chromatography tandem mass spectrometry. A total of 96 spots had a significant average change of at least 1.25-fold in 1 of the 3 comparisons. Compared with the CSF of control dogs, CSM-affected dogs demonstrated increased CSF expression of 8 proteins including vitamin D-binding protein, gelsolin, creatine kinase B-type, angiotensinogen, α-2-HS-glycoprotein, SPARC (secreted protein, acidic, rich in cysteine), calsyntenin-1, and complement C3, and decreased expression of pigment epithelium-derived factor, prostaglandin-H2 D-isomerase, apolipoprotein E, and clusterin. In the CSF of CSM-affected dogs, corticosteroid treatment increased the expression of haptoglobin, transthyretin isoform 2, cystatin C-like, apolipoprotein E, and clusterin, and decreased the expression of angiotensinogen, α-2-HS-glycoprotein, and gelsolin. Many of the differentially expressed proteins are associated with damaged neural tissue, bone turnover, and/or compromised blood-spinal cord barrier. The knowledge of the protein changes that occur in CSM and upon corticosteroid treatment of CSM-affected patients will aid in further understanding the pathomechanisms underlying this disease. N/A.

The traditional surgical approach to treat multi-level cervical disc disease (mCDD) has been anterior cervical discectomy and fusion (ACDF). There has been recent development of other surgical approaches to further improve clinical outcomes. Collectively, when elements of these different approaches are combined in surgery, it is known as hybrid surgery (HS) which remains a novel treatment option. A systematic review and meta-analysis was conducted to compare the outcomes of HS versus ACDF for the treatment of mCDD. Relevant articles were identified from six electronic databases from their inception to January 2016. From 8 relevant studies identified, 169 patients undergoing HS were compared with 193 ACDF procedures. Operative time was greater after HS by 42 min (p < 0.00001), with less intraoperative blood loss by 26 mL (p < 0.00001) and shorter return to work by 32 days (p < 0.00001). In terms of clinical outcomes, HS was associated with greater C2-C7 range of motion (ROM) preservation (p < 0.00001) and less functional impairment (p = 0.008) after surgery compared to ACDF. There was no significant difference between HS and ACDF with respect to postoperative pain (p = 0.12). The postoperative course following HS was not significantly different to ACDF in terms of length of stay (p = 0.24) and postoperative complication rates (p = 0.18). HS is a novel surgical approach to treat mCDD, associated with a greater operative time, less intraoperative blood loss and comparable if not superior clinical outcomes compared to ACDF. While it remains a viable consideration, there is a lack of robust clinical evidence in the literature. Future large prospective registries and randomised trials are warranted to validate the findings of this study.

Purpose: To investigate, in a prospective trial, the acute and chronic toxicity of patients with cervical cancer treated with surgery and postoperative intensity-modulated radiotherapy (RT) delivered using helical tomotherapy, with or without the administration of concurrent chemotherapy. Patients and Methods: A total of 24 evaluable patients entered the study between March 2006 and August 2009. The indications for postoperative RT were tumor size, lymphovascular space invasion, and the depth of cervical stromal invasion in 15 patients; 9 patients underwent postoperative RT because of surgically positive lymph nodes. All patients underwent pelvic RT delivered with helical tomotherapy and intracavitary high-dose-rate brachytherapy.more » Treatment consisted of concurrent weekly platinum in 17, sequential carboplatin/Taxol in 1, and RT alone in 6. The patients were monitored for acute and chronic toxicity using the Common Toxicity Criteria, version 3.0. Results: The median follow-up was 24 months (range, 4-49). At the last follow-up visit, 23 patients were alive and disease free. Of the 24 patients, 12 (50%) experienced acute Grade 3 gastrointestinal toxicity (anorexia in 5, diarrhea in 4, and nausea in 3). One patient developed acute Grade 4 genitourinary toxicity (vesicovaginal fistula). For patients treated with concurrent chemotherapy, the incidence of acute Grade 3 and 4 hematologic toxicity was 71% and 24%, respectively. For patients treated without concurrent chemotherapy, the incidence of acute Grade 3 and 4 hematologic toxicity was 29% and 14%, respectively. Two long-term toxicities occurred (vesicovaginal fistula at 25 months and small bowel obstruction at 30 months). The overall and progression-free survival rate at 3 years for all patients was 100% and 89%, respectively. Conclusion: The results of our study have shown that postoperative external RT for cervical cancer delivered with helical tomotherapy and high-dose-rate brachytherapy and with or without chemotherapy is feasible, with acceptable acute and chronic toxicity.« less

The objective of this study is to understand the prevalence of short cervical length between 20 and 24 weeks gestation in China and to evaluate the efficacy of micronized progesterone for prolonging gestation in nulliparous patients with a short cervix. From May 2010 to May 2015, a total of 25 328 asymptomatic women with singleton pregnancies at Peking University First Hospital had their cervical length routinely measured between 20 and 24 weeks of gestation. A cervical length of 25 mm or less was defined as a shortened cervical length. The therapies prescribed include vaginal micronized progesterone capsules (200 mg each night) or bed rest from 20 to 34 weeks of gestation. The primary outcome was spontaneous delivery before 33 weeks. (1) One hundred fourteen women had a cervical length of ≤25 mm (0.45%). (2) Twenty-nine of which with previous spontaneous preterm delivery or late pregnancy loss had cervical cerclage, the remaining 85 women by the use of vaginal progesterone or simply resting activity restriction to prevent preterm birth. (3) In 85 nulliparous women treated by progesterone or bed rest, progesterone use in cervical length between 10 and 20 mm was associated with a statistically significant reduction in the incidence of preterm birth at <33 weeks of gestation (9.5% versus 45.5%, p = 0.02) compared with bed rest. There were no significant differences in cervical length between 20 and 25 mm in their rates of spontaneous preterm delivery at <33 (5.3% versus 3.2%, p = 0.72), <37 (33.3% versus 54.5%, p = 0.25), or <35 weeks (14.3% versus 45.5, p = 0.06) of gestation between vaginal progesterone and bed rest. The rate of short cervical length was less than expected. Vaginal progesterone is efficacious for the prolonging of gestation in women with a cervical length of 10-20 mm in the mid-trimester for a singleton gestation and nulliparous women. For a cervical length of 20-25 mm in the mid trimester, vaginal progesterone compared with bed rest did not prolong pregnancy.

Purpose: Constitutively activated signal transducers and activators of transcription (STAT) factors, in particular STAT1, STAT3, and STAT5, have been detected in a wide variety of human primary tumors and have been demonstrated to directly contribute to oncogenesis. However, the expression pattern of these STATs in cervical carcinoma is still unknown, as is whether or not they have prognostic significance. This study investigated the expression patterns of STAT1, STAT3, and STAT5 in cervical cancer and their associations with clinical outcomes in patients treated with radical radiation therapy. Methods and Materials: A total of 165 consecutive patients with International Federation of Gynecologymore » and Obstetrics (FIGO) Stages IB to IVA cervical cancer underwent radical radiation therapy, including external beam and/or high-dose-rate brachytherapy between 1989 and 2002. Immunohistochemical studies of their formalin-fixed, paraffin-embedded tissues were performed. Univariate and multivariate analyses were performed to identify and to evaluate the effects of these factors affecting patient survival. Results: Constitutive activations of STAT1, STAT3, and STAT5 were observed in 11%, 22%, and 61% of the participants, respectively. While STAT5 activation was associated with significantly better metastasis-free survival (p < 0.01) and overall survival (p = 0.04), STAT1 and STAT3 activation were not. Multivariate analyses showed that STAT5 activation, bulky tumor ({>=}4 cm), advanced stage (FIGO Stages III and IV), and brachytherapy (yes vs. no) were independent prognostic factors for cause-specific overall survival. None of the STATs was associated with local relapse. STAT5 activation (odds ratio = 0.29, 95% confidence interval = 0.13-0.63) and advanced stage (odds ratio = 2.54; 95% confidence interval = 1.03-6.26) were independent predictors of distant metastasis. Conclusions: This is the first report to provide the overall expression patterns and prognostic significance of specific STATs in cervical carcinoma. Our results indicate that constitutive STAT5 activation correlates with better metastasis-free survival and overall survival in cervical cancer patients who have received radiation therapy.« less

Are treatments for cervical precancerous lesions in less-developed countries safe enough to promote scaling-up of cervical screening programs? A systematic review.

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

Ersmark, H; Kalen, R

1987-04-01

In a follow-up study of ten atlas and 85 axis fractures, 12% had residual symptoms in the form of local and radiating cervical pain. The residual symptoms were interpreted as a sign of a mild demyelinating process initiated by the trauma of the medulla. At least 22% of the accidents occurred while the person was under the influence of drugs or alcohol. Therefore, a wide range of residual symptoms (progressive or nonprogressive) could be attributed in part to abuse of drugs and alcohol. A permanent measurable loss of motion occurred following injury to the atlas or axis, irrespective of the modality of treatment. Cervical fusion created the greatest loss of motion and collar immobilization the least. Skull traction and a halo-vest were intermediate in patients with loss of motion, and the degree of loss of range was essentially equal. Residual symptoms, including pain, were found in 20% of those treated with a collar, 40% of those treated with surgical methods, 5% of those treated with traction, and 5% of those treated with a Halo-vest. Residual symptoms did not correlate at all with degree of displacement of the original fracture.

Genital infection is a common worldwide disease among females with clinical features such as bilateral lower abdominal tenderness, abnormal vaginal or cervical discharge, fever, abnormal vaginal bleeding, dyspareunia, vaginal itching, and adnexal tenderness, which can significantly impair women's health and quality of life. Genital infection is commonly treated with antibiotics, leading to an imbalance in gut flora due to prolonged use of antibiotics. Therefore, it is necessary to discover safe and efficacious alternative treatment strategies for patients with genital infection. Complementary and alternative medicine (CAM) is becoming increasingly prevalent among women with genital infection. CAM has interested the western mainstream medical community because of its less invasive, safe, effective, economical, and convenient therapies. CAM focuses on the prevention and treatment of disease and has become an important force in treating chronic disease. During the last few decades, the popularity of CAM has gradually increased. To further understand the efficacy of CAM in treating genital infection, our paper will review the current progress of treating genital infection including vulvitis, vaginitis, cervicitis, and pelvic inflammatory disease (PID) with CAM therapies. Several CAM strategies including traditional Chinese medicine (TCM), acupuncture, Psychology interference, and physical therapy are introduced in this review. PMID:24648850

Type II fractures of the odontoid process of the axis are the most common injury of the cervical spine in elderly patients. Only little evidence exists on whether elderly patients should be treated conservatively or surgically. The mortality and survival probability of 51 patients were determined in a retrospective study. The range of motion, pain and the neck disability index were clinically investigated. Of the 51 patients 37 were treated surgically and 14 conservatively. The conservatively treated group showed a higher mortality (64 % vs. 32 %). Kaplan-Meier analysis revealed a median survival of the conservatively treated group of 29 months, whereby during the first 3 months of treatment this group showed a higher survival probability and afterwards the surgically treated group showed a higher survival probability. The clinical examination of 20 patients revealed limited range of motion of the cervical spine. Additionally, moderate levels of pain and complaints were recorded using the neck disability index. Fractures of the odontoid process pose a far-reaching danger for elderly patients. A balanced assessment of the general condition should be carried out at the beginning of treatment of these patients. In the early phase following trauma no differences were found with respect to survival rates but for long-term survival the operatively treated group showed advantages; however, these advantages cannot be causally attributed to the choice of therapy.

Cervical cancer screening among women who attend sexually transmitted diseases (STD) clinics: background paper for 2010 STD Treatment Guidelines.

In April 2008, experts reviewed updates on sexually transmitted disease (STD) prevention and treatment in preparation for the revision of the Centers for Disease Control and Prevention (CDC) STD Treatment Guidelines. This included a review of cervical cancer screening in the STD clinical setting. Key questions were identified with assistance from an expert panel. Reviews of the literature were conducted using the PubMed computerized database and shared with the panel. Updated information was incorporated in the 2010 CDC STD Treatment Guidelines. We recommend that STD clinics offering cervical screening services screen and treat women according to guidelines by the American College of Obstetrics and Gynecology, the American Cancer Society, the US Preventive Services Task Force, and the American Society for Colposcopists and Cervical Pathologists. New to the 2010 guidelines are higher age for initiating cervical screening (age ≥ 21 years) and less frequent intervals of screening (at least every 3 years). New recommendations include new technologies, such as liquid-based cytology and high-risk human papillomavirus (HPV) DNA tests. Liquid-based technologies are not recommended over conventional testing. HPV DNA tests are recommended as adjunct tests and with new indications for use in cervical screening and management. Stronger recommendations were issued for STD clinics offering cervical screening services to have protocols in place for follow-up of test results and referral (eg, colposcopy). Important additions to the 2010 STD Treatment Guidelines include information on updated algorithms for screening and management of women and recommendations for use of liquid-based cytology and high-risk HPV testing.

miR-25-3p reverses epithelial-mesenchymal transition via targeting Sema4C in cisplatin-resistance cervical cancer cells.

PubMed

2017-01-01

Acquisition of epithelial-mesenchymal transition (EMT) has recently been proposed as an important contributor of drug resistance in cervical cancer cells. However, the underlying mechanisms are still unclear. MicroRNAs play a crucial role in regulating EMT. The aim of this study was to explore the potential role of miR-25-3p in regulating EMT in cisplatin-resistant (CR) cervical cancer cells. To this end, we established stable CR cervical cancer cells, HeLa-CR and CaSki-CR, and investigated the function of miR-25-3p in regulating EMT. It is found that CR cervical cancer cells possessed more EMT characteristics and demonstrated higher migratory abilities and invasiveness. miR-25-3p downregulation was also seen in HeLa-CR and CaSki-CR cells. Of note, ectopic expression of miR-25-3p reversed the EMT phenotype and sensitized CR cells to cisplatin via targeting Sema4C. Furthermore, stable overexpression of miR-25-3p in HeLa-CR cells suppressed tumor growth in mice, downregulated Sema4C and Snail, and upregulated E-cadherin compared with the control group. These results suggest that miR-25-3p is an important regulator of cervical cancer EMT and chemoresistance. Thus, upregulation of miR-25-3p could be a novel approach to treat cervical cancers that are resistant to chemotherapy. © 2016 The Authors.

Study Design: Retrospective trends analysis. Objectives: Cervical fusion is a common adjunctive surgical modality used in the treatment of cervical spondylotic myelopathy (CSM). The purpose of this study was to quantify national trends in patient demographics, hospital characteristics, and outcomes in the surgical management of CSM. Methods: This was a retrospective study that used the National Inpatient Sample. The sample included all patients over 18 years of age with a diagnosis of CSM who underwent cervical fusion from 2003 to 2013. The outcome measures were in-hospital mortality, length of stay, and hospital charges. Chi-square tests were performed to compare categorical variables. Independent t tests were performed to compare continuous variables. Results: We identified 62 970 patients with CSM who underwent cervical fusion from 2003 to 2013. The number of fusions performed per year in the treatment of CSM increased from 3879 to 8181. The average age of all fusion patients increased from 58.2 to 60.6 years (P < .001). Length of stay did not change significantly from a mean of 3.7 days. In-hospital mortality decreased from 0.6% to 0.3% (P < .01). Hospital charges increased from $49 445 to $92 040 (P < .001). Conclusions: This study showed a dramatic increase in cervical fusions to treat CSM from 2003 to 2013 concomitant with increasing age of the patient population. Despite increases in average age and number of comorbidities, length of stay remained constant and a decrease in mortality was seen across the study period. However, hospital charges increased dramatically.

Women screened for cervical cancer in Sweden are currently treated under a one-size-fits-all programme, which has been successful in reducing the incidence of cervical cancer but does not use all of the participants' available medical information. This study aimed to use women's complete cervical screening histories to identify diagnostic patterns that may indicate an increased risk of developing cervical cancer. A nationwide case-control study was performed where cervical cancer screening data from 125,476 women with a maximum follow-up of 10 years were evaluated for patterns of SNOMED diagnoses. The cancer development risk was estimated for a number of different screening history patterns and expressed as Odds Ratios (OR), with a history of 4 benign cervical tests as reference, using logistic regression. The overall performance of the model was moderate (64% accuracy, 71% area under curve) with 61-62% of the study population showing no specific patterns associated with risk. However, predictions for high-risk groups as defined by screening history patterns were highly discriminatory with ORs ranging from 8 to 36. The model for computing risk performed consistently across different screening history lengths, and several patterns predicted cancer outcomes. The results show the presence of risk-increasing and risk-decreasing factors in the screening history. Thus it is feasible to identify subgroups based on their complete screening histories. Several high-risk subgroups identified might benefit from an increased screening density. Some low-risk subgroups identified could likely have a moderately reduced screening density without additional risk. © 2017 UICC.

This report describes a new, minimally invasive procedure, posterior percutaneous endoscopic cervical diskectomy, performed with a unilateral biportal endoscopic approach. The procedure is used to treat cervical foraminal soft disk protrusion. This report also describes the short-term results with this procedure. In 2015, 14 patients underwent this new, minimally invasive procedure. The technique was applied with a standard arthroscopy device and conventional spine instruments. The Neck Disability Index and visual analog scale scores for the neck and upper arm were evaluated, and 13 consecutive patients were included in the analysis. Mean follow-up was 14.8 months (range, 12-18 months). The Neck Disability Index decreased from 27.0±2.5 to 6.8±1.4 at the last follow-up (P<.05). Visual analog scale scores for the neck and upper arm also decreased significantly (neck, 6.2±0.8 to 2.4±0.9; upper arm, 7.0±1.1 to 2.2±0.6). Posterior percutaneous endoscopic cervical diskectomy with a uniportal endoscope provides a clear operative field because of continuous endoscopic saline irrigation and requires only a short hospitalization and no postoperative rehabilitation. Posterior percutaneous endoscopic cervical diskectomy with a unilateral biportal endoscopic approach also can be performed efficiently because of the wide field of visualization and familiar surgical field. Thus, posterior percutaneous endoscopic cervical diskectomy with the unilateral biportal endoscopic approach may be an alternative procedure for cervical foraminal soft disk protrusion.

Abstract Objective To understand better the current regional situation and public health response to cervical cancer and female breast cancer in the Americas. Methods Data on cervical cancer and female breast cancers in 33 countries, for the period from 2000 to the last year with available data, were extracted from the Pan American Health Organization (PAHO) Regional Mortality Database and analysed. Changes in mortality rates over the study period – in all countries except those with small populations and large fluctuations in time–series mortality data – were calculated using Poisson regression models. Information from the PAHO Country Capacity Survey on noncommunicable diseases was also analysed. Findings The Bahamas, Trinidad and Tobago and Uruguay showed relatively high rates of death from breast cancer, whereas the three highest rates of death from cervical cancer were observed in El Salvador, Nicaragua and Paraguay. Several countries – particularly Paraguay and Venezuela – have high rates of death from both types of cancer. Although mortality from cervical cancer has generally been decreasing in the Americas, decreases in mortality from breast cancer have only been observed in a few countries in the Region of the Americas. All but one of the 25 countries in the Americas included in the PAHO Country Capacity Survey reported having public health services for the screening and treatment of breast and cervical cancers. Conclusion Most countries in the Americas have the public health capacity needed to screen for – and treat – breast and cervical cancers and, therefore, the potential to reduce the burden posed by these cancers.

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

Cervical cancer is the leading incident cancer and the main cause of cancer-related mortality among women in sub-Saharan Africa. Furthermore, HIV-infected women are at a higher risk of developing cervical cancer than HIV-negative women. The purpose of this study was to distinguish differences in characteristics of HIV-positive and HIV-negative patients with cervical cancer in Dar es Salaam, Tanzania. The HIV status of cervical cancer patients diagnosed and/or treated at Ocean Road Cancer Institute in Dar es Salaam, Tanzania, during the period 2007-2011 was abstracted from the medical records. Additional abstracted information included patient's name, age, place of residence, occupation, education, marital status, age at marriage, gravidity, and screening clinic visit results. Ocean Road Cancer Institute patients came from two sources: the screening clinic followed by treatment clinic or the treatment clinic without prior screening. HIV-positive and HIV-negative patients were compared regarding the above-listed clinical and epidemiologic factors. Multivariable analysis was also performed to assess the risk factors associated with cervical cancer treatment without prior screening at Ocean Road Cancer Institute. HIV-positive cervical cancer patients tended to be younger, with higher education and lower parity. Patients screened for cervical cancer prior to treatment were more likely to be HIV-positive (OR: 2.09, 95% CI: 1.36, 3.21), less likely to have higher disease stages (OR: 0.64, 95% CI: 0.43, 0.94), and less likely to reside outside of Dar es Salaam (OR: 0.44, 95% CI: 0.30, 0.65). Screening for cervical cancer at Ocean Road Cancer Institute is utilised by more HIV-positive patients from Dar es Salaam. Future studies should focus on identifying the reasons for lower utilisation of screening by HIV-negative patients and patients from other distant rural regions in Tanzania. © The Author(s) 2016.

Cancer of uterine cervix is the second most common cause of cancer related deaths among women. The aim of this study is to report the experience of Military Hospital Mohamed V in the management of cervical cancer and their results. All cervical cancer managed at the radiotherapy department of Military Hospital Mohamed V between January 2005 and February 2010, were included for investigation of their demographic, histological, therapeutic and follow-up characteristics. Of the 162 cases managed, 151 (93.2 %) cases were treated in our department. In our study the median age was 51.5 years (33-82). The median duration of symptoms before diagnosis was four [3, 7] months. The major presenting complaints were abnormal vaginal bleeding (89.8 %). Squamous cell carcinoma cervix was seen in 86.2 % (n = 137), adenocarcinoma in 11.3 % (n = 18) and adenosquamous carcinoma in 2.4 % (n = 4). One hundred seventeen (84.8 %) cases were seen at late stage. An abdominal and pelvic computed tomography (CT) scan was performed in 34.6 % (n = 56) of cases, magnetic resonance imaging (MRI) in 62.9 % (n = 102). The pelvic lymph nodes were achieved in 16.6 % of cases. Over half of patients 58.3 % (n = 88) were treated with a combination of external beam radiation therapy (EBRT) and a concurrent cisplatin based chemotherapy (40 mg /m2 weekly). With a mean of 51.6 months (2 to 109), we recorded 19 (12.6 %) pelvic relapse and 15 (9.9 %) metastases. The median time to onset was 19.4 months (2-84 months). The local control rate was 63.6 % (n = 96) and 21 (13.9 %) patients were lost to follow-up. The overall survival (OS) at 3 years and 5 years was respectively 78.3 % and 73.6 % and the relapse-free survival (RFS) was respectively 80 % and 77.2 %. Most of cervical cancer patients in Morocco are seen at late stage necessitating referral for radiotherapy, chemotherapy or palliative care. This may reflect lack of cervical screening in order to early detect and treat pre-malignant disease stage.

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 (P<.01). No significant group-by-time interactions were found for cervical 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 changes in active cervical range of motion, except for rotation. Changes in neck pain surpassed the minimal clinically important difference, whereas changes in disability did not. Changes in cervical range of motion were small and not clinically meaningful. Because we did not include a control or placebo group in this study, we cannot rule out a placebo effect or natural changes over time as potential reasons for the improvements measured in both groups.

Transvertebral foraminotomy (TVF) combined with anterior cervical decompression and fusion (ACDF) can be used to treat multilevel cervical spondylotic myelopathy and radiculopathy; however, the radiological outcomes and effectiveness of this hybrid procedure are unknown. We retrospectively assessed 22 consecutive patients treated with combined TVF and ACDF between January 2007 and May 2016. The Japanese Orthopedic Association (JOA) score and Odom's criteria were analyzed. Radiological assessment included the C2-7 sagittal Cobb angle (CA) and range of motion (ROM). The tilting angle (TA), TA ROM, and disc height (DH) of segments adjacent to the ACDF were also measured. Adjacent segment degeneration, which includes disc degeneration, was evaluated. The mean postoperative follow-up was 41.7 months. All surgeries were performed at two adjacent segments, with ACDF and TVF of the upper and lower segments, respectively. The JOA scores significantly improved. There were no significant differences in the C2-7 CA, C2-7 ROM, TA, and TA ROM, but there was a statistically significant decrease in DH of the lower adjacent segment to ACDF. Progression of disc degeneration was identified in two patients, with no progression in the criterion of adjacent segment degeneration over the follow-up. The TVF combined with ACDF produced excellent clinical results and maintained spinal alignment, albeit with a reduction in DH. TVF was safely performed at the lower segment adjacent to the ACDF, although this might result in earlier degeneration. In conclusion, this hybrid method is less invasive and beneficial for reduction of the number of fused levels.

Patients presenting with gunshot wounds (GSWs) to the neck are difficult to assess because of their injuries are often severe and they are incompletely evaluated by computed tomography (CT) alone. Our institution treats hundreds of patients with GSWs each year and we present our experience using magnetic resonance imaging (MRI) in the evaluation of cervical GSWs. From August 2000 to July 2012, all GSWs to the cervical spine treated at our institution were cataloged. Seventeen patients had 1 or more MRI studies of the cervical spine. Informed consent was obtained before MRI indicating the risks of retained metal fragments in the setting of high magnetic fields. CT scans were obtained before and after MRI to document any possible migration of metal fragments. We documented patients' neurologic examination results before and after MRI and at follow-up. Patients' age range was 18-56 years (mean 29.8 years). Eleven of 17 patients had retained metal fragments seen on CT scan, including 3 patients with fragments within the spinal canal. No patient experienced a decline in neurologic function after MRI. No migration of retained fragments was observed. Fifteen of 17 patients returned for follow-up examinations, with an average follow-up interval of 39.1 weeks (range, 1.3-202.3 weeks; median, 8 weeks). For carefully selected patients, MRI can be an effective tool in assessing GSWs to the neck and it can significantly improve the evaluation and management of this cohort. No patient in our series experienced a complication related to MRI. Copyright © 2015 Elsevier Inc. All rights reserved.

Purpose: To evaluate the risk of cardiovascular events (CVE) in patients with cervical cancer treated with radiotherapy or chemoradiation. Methods and Materials: The incidence of CVE in patients treated between 1989 and 2002 by radiotherapy or chemoradiation was compared with a Dutch reference population. Standardized incidence ratios (SIRs) were calculated for myocardial infarction (MI), angina pectoris (AP), congestive heart failure (CHF), cerebrovascular accident (CVA) separately and for any cardiac event combined (MI, AP, and CHF). Results: In 277 patients with a median follow-up of 4.5 years (range, 0.1-17 years) and a median survival of 9.2 years, 27 cardiac events occurred.more » The 5-, 10-, and 15-year actuarial incidence of any cardiac event were 9, 14, and 16%, respectively. For the whole population, the SIR for MI was elevated (2.05, 95% CI: 1.12-3.43). The radiotherapy group (n = 132) was older and had more cardiovascular risk factors than the chemoradiation group (n = 145). The SIR for MI in the radiotherapy group was 2.88 (95% CI: 1.44-5.15) and in the chemoradiation group 1.00 (95% CI: 0.21-7.47). In multivariate analyses, there was no relation between treatment modality and the risk for MI. Conclusions: In this cohort of cervical cancer patients, an increased risk for developing a MI was observed. This increased risk of MI, in combination with the high prevalence of cardiovascular risk factors in cervical cancer patients, urges the need to explore strategies to reduce their risk for cardiovascular morbidity.« less

The objective was to analyze the outcomes of the patients, who received salvage radiotherapy for incidentally discovered cervical cancer following simple hysterectomy, and to identify the influence of intracavitary radiotherapy on treatment outcomes. Data from 117 patients with occult cervical cancer who underwent simple hysterectomy followed by salvage radiotherapy from September 1979 to November 2010 were collected. All the patients received external beam radiotherapy with (n = 45) or without (n = 72) intracavitary radiotherapy. Local control, disease-free survival, overall survival and treatment-related toxicity were investigated. The median follow-up time was 75 months. The 5- and 10-year local control/disease-free survival/overall survival rates were 93/87/87% and 90/84/83%, respectively. Among 98 patients who had no residual disease and negative resection margin on surgical specimens, 32 (33%) received intracavitary radiotherapy and 66 (67%) did not. There were no differences in patient and tumor characteristics between patients treated with and without intracavitary radiotherapy. The 5-year local control rate for the non-intracavitary radiotherapy group was 93 versus 94% for the intracavitary radiotherapy group (P = 0.564); the disease-free survival rate was 88 versus 94% (P = 0.894); the overall survival rate was 95 versus 85% (P = 0.106), respectively. Among all patients, there were 5% of Grade 3 or higher late toxicities. Patients with occult invasive cervical cancer discovered following simple hysterectomy could be treated safely and effectively with salvage radiotherapy. For patients with no residual disease and negative resection margin, intracavitary radiotherapy could be omitted.

Cervical carotid aneurysms are rare, and surgical treatment should be planned for each patient. The authors report 9 cases of cervical carotid aneurysm in 9 patients(mean age, 53.7 years;5 men)who were treated surgically between 2005 and 2014. The aneurysm was located in the internal carotid artery in 6 patients, the common carotid artery in 2 patients, and the carotid bifurcation in 1 patient. Four aneurysms were recurrences after a previous endovascular intervention(parent artery coil embolization, covered stent placement, or stent with coil embolization). The mean interval between the endovascular therapy and the onset of the present illness was 6 years. All the patients presented a mass effect at the neck, including lower cranial nerve dysfunction in 1 patient. Two patients presented with ischemic events presumably due to thromboembolism from the target aneurysms. Surgical treatments included local vascular reconstruction procedures in 6 patients(interposition vein or artificial graft bypass in 5 patients and in situ bypass in 1 patient). Four aneurysms were then resected. Two patients with rich collateral blood flow were treated with ligation of the parent artery proximal to the aneurysm. Surgical complications included embolic stroke and cranial nerve dysfunction in 2 patients, respectively, both presumably due to surgical manipulation. The modified Rankin scale(mRS)score at discharge was 0 in 5 patients, 1 in 1 patient, 2 in 2 patients, and 6 in 1 patient(vascular tumor). Surgical treatment of cervical carotid aneurysms seems a reasonable treatment of choice, but lower nerve dysfunction and embolism from the aneurysm should be avoided.

Focus groups and in-depth interviews with women being treated for cervical-uterine cancer within the Andalusian Health Service. Analysis with Nudist Vivo 1.0 (QSR International Pty Ltd, Doncaster, Victoria, Australia). The needs and expectations detected were: coherence in the promotion strategies and the presence of a proactive approach by health professionals, availability of comprehensive information and understanding, possibility of expressing to health professionals one's doubts and fears, and of participation in decision-making, technical quality, humane treatment and continuity of care and attention to psychosocial aspects. The knowledge of women in the treatment of cancer of the cervix and uterus plays a crucial part in improving the delivery of these services.

Analysis of the Cytotoxic Potential of Anisomelic Acid Isolated from Anisomeles malabarica

2013-01-01

Anisomelic acid (AA), one of the major compounds in Anisomeles malabarica, was tested for its cytotoxicity and apoptosis-inducing potential in breast and cervical cancer cells. The MTT assay for cell viability indicated that AA is cytotoxic to all of the four cell lines tested in a dose- and duration-dependent manner. Acridine Orange & Ethidium Bromide (AO & EB) and Hoechst 33258 staining of AA-treated cells revealed typical apoptotic morphology such as condensed chromatin and formation of apoptotic bodies. The comet assay revealed DNA strand break(s), indicating that AA induces DNA damage which culminates in apoptosis. Thus, the study revealed the anti-proliferative and apoptosis-inducing properties of AA in both breast and cervical cancer cells. Therefore, anisomelic acid offers potential for application in breast and cervical cancer therapy. PMID:23833721

[Minimally invasive approach for cervical spondylotic radiculopathy].

PubMed

Ding, Liang; Sun, Taicun; Huang, Yonghui

2010-01-01

To summarize the recent minimally invasive approach for cervical spondylotic radiculopathy (CSR). The recent literature at home and abroad concerning minimally invasive approach for CSR was reviewed and summarized. There were two techniques of minimally invasive approach for CSR at present: percutaneous puncture techniques and endoscopic techniques. The degenerate intervertebral disc was resected or nucleolysis by percutaneous puncture technique if CSR was caused by mild or moderate intervertebral disc herniations. The cervical microendoscopic discectomy and foraminotomy was an effective minimally invasive approach which could provide a clear view. The endoscopy techniques were suitable to treat CSR caused by foraminal osteophytes, lateral disc herniations, local ligamentum flavum thickening and spondylotic foraminal stenosis. The minimally invasive procedure has the advantages of simple handling, minimally invasive and low incidence of complications. But the scope of indications is relatively narrow at present.

2016-06-17

In patients with C2 rheumatoid pannus with spinal cord compression the treatment of choice is extensive surgery either through a transoral resection of the dens axis or a dorsal stabilisation, or both. We present a case of an 11-mm rheumatoid pannus with significant compression of the spinal cord, which failed surgical treatment with respect to dorsal stabilisation. Therefore, rigid cervical collar for 8 weeks followed by soft collar for another 4 weeks was chosen as a treatment option. During the follow-up period of 1 year, the pannus reduced significantly and the spinal cord decompressed. In cases where surgery is not an option or is technically very demanding, the alternative of cervical collar immobilisation is a satisfying option.

Fracture of the First Cervical Vertebra in a High School Football Player: A Case Report

Trupiano, Tim P.; Sampson, Michelle L.; Weise, Marc W.

1997-01-01

Objective: To present the case of a high school football player with a burst fracture of the ring of C1 resulting from a “spearing” tackle. Background: Cervical spine fractures are rare in collision sports, but their potentially grave consequences mean that they must be given special attention. Spearing was banned by the National Collegiate Athletic Association and the National Federation of High School Athletic Associations in 1976, and the number of cervical spine fractures in high school and college football players has fallen dramatically. However, cervical spine fractures do still occur, and they present a diagnostic challenge to sports medicine professionals. Differential Diagnosis: Cervical sprain. Treatment: Treatment consists of halo-vest immobilization. Surgical fusion may be necessary for unstable C1-C2 fractures, although initial halo-vest treatment is usually attempted. Uniqueness: A 17-year-old defensive back attempted to make a tackle with his head lowered. He was struck on the superolateral aspect of the helmet by the opposing running back. He remained in the game for another play, but then left the field under his own power, complaining of neck stiffness and headache. Physical examination revealed upper trapezius and occiput tenderness, bilateral cervical muscle spasm, and pain at all extremes of voluntary cervical movement. He was alert and oriented, with a normal neurologic examination. Treatment with ice was attempted but was discontinued due to increased pain and stiffness. Heat resulted in decreased pain and stiffness, but his symptoms persisted, and he was trans- ported to the emergency room. Plain radiographs were read as negative, but a CT scan demonstrated a burst fracture of Cl. He was treated with halo-vest immobilization for 8 weeks and a rigid cervical collar for 8 additional weeks. Physical therapy was then initiated, and normal cervical range of motion and strength were restored within 6 weeks. The athlete competed in track 6 months after the injury and continues to play recreational sports without difficulty. At clinical follow-up 8 months after injury, he had full, painless cervical range of motion and a normal neurologic examination. Conclusions: A potentially devastating cervical spine injury can present insidiously, without dramatic signs or symptoms. Therefore, sports medicine professionals must retain a high index of suspicion when evaluating athletes with cervical spine complaints. ImagesFig 1.Fig 2. PMID:16558448

Cervical kyphosis may occur with neurofibromatosis type I (NF1) and is often associated with vertebral dysplasia. Outcomes of cervical spinal fusion in patients with NF1 are not well described because of the rarity of the condition. We aimed to (1) characterize the clinical presentation of cervical kyphosis and (2) report the outcomes of posterior and anteroposterior cervical fusion for the condition in these children. The medical records and imaging studies of 22 children with NF1 who had undergone spinal fusion for cervical kyphosis (mean, 67°) at a mean age of 11 years and who had been followed for a minimum of 2 years were reviewed. Thirteen children presented with neck pain; 10, with head tilt; 9, with a previous cervical laminectomy or fusion; and 5, with a neurologic deficit. Two patients had spontaneous dislocation of the mid-cervical spine without a neurologic deficit. Eleven had scoliosis, with the major curve measuring a mean of 61°. Nine patients underwent posterior and 13 underwent anteroposterior surgery. Twenty-one received spinal instrumentation, and 1 was not treated with instrumentation. Preoperative halo traction was used for 9 patients, and it reduced the mean preoperative kyphosis by 34% (p = 0.0059). At the time of final follow-up, all spinal fusion sites had healed and the cervical kyphosis averaged 21° (mean correction, 69%; p < 0.001). The cervical kyphosis correction was significantly better after the anteroposterior procedures (83%) than after the posterior-only procedures (58%) (p = 0.031). Vertebral dysplasia and erosion continued in all 17 patients who had presented with dysplasia preoperatively. Thirteen patients had complications, including 5 new neurologic deficits and 8 cases of junctional kyphosis. Nine patients required revision surgery. Junctional kyphosis was more common in children in whom ≤5 levels had been fused (p = 0.054). Anteroposterior surgery provided better correction of cervical kyphosis than posterior spinal fusion in children with NF1. Erosion of vertebral bodies continued during the postoperative follow-up period in all patients who had presented with dysplastic changes preoperatively. The cervical spine should be screened in all children with NF1. Fusion should include at least 6 levels to prevent junctional kyphosis. Therapeutic Level III.

This is prospective observational study. To prospectively investigate the correlation among axial neck pain; a newly developed patient-based quality of life outcome measure, the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ); and cervical sagittal alignment after open-door laminoplasty for cervical myelopathy. Many studies have focused on postoperative axial neck pain after laminoplasty. However, the correlation among cervical sagittal alignment, neck pain, and JOACMEQ has not been investigated. In total, 57 consecutive patients treated by open-door laminoplasty for cervical myelopathy were included (mean age, 63.7 y; 15 women and 42 men) and divided into 2 groups according to diagnosis [cervical spondylotic myelopathy (CSM) group: 35 patients, and ossification of the posterior longitudinal ligament (OPLL) group: 22 patients]. JOA score, a subdomain of cervical spine function (CSF) in the JOACMEQ, and the visual analog scale for axial neck pain were assessed preoperatively and 12 months postoperatively. Radiographic cervical sagittal parameters were measured by C2 sagittal vertical axis (C2 SVA), C2-C7 lordosis, C7 sagittal slope (C7 slope), and range of motion. C2 SVA values in both groups shifted slightly anteriorly between preoperative and 12-month postoperative measurements (CSM: +19.7±10.9 mm; OPLL: +22.1±13.4 mm vs. CSM: +23.2±16.1 mm; OPLL: +28.7±15.4 mm, respectively). Postoperative axial neck pain in the OPLL group showed strong negative correlations with C2 SVA and C7 slope. Strong negative correlations were found between axial neck pain and CSF in both the preoperative CSM and OPLL groups (CSM: r=-0.45, P=0.01; OPLL: r=-0.61, P<0.01) and between axial neck pain and CSF in the postoperative OPLL group (r=-0.51, P=0.05). This study demonstrated a significant negative correlation between neck pain and CSF in both the CSM and OPLL groups preoperatively and in the OPLL group postoperatively. Radiographic cervical sagittal alignment did not significantly correlate with preoperative or postoperative axial neck pain.

To investigate the treatment methods and the clinical therapeutic effects of symptomatic cervical vertebral hemangioma associated with cervical spondylotic myelopathy. A retrospective analysis was performed in 18 patients (10 males and 8 females, aged 30-62 years with an average age of 45.3 years) with cervical vertebral hemangioma associated with cervical spondylotic myelopathy between January 2006 and September 2008. The disease duration was 10-26 months (mean, 15.6 months). All patients had single vertebral hemangioma, including 2 cases at C3, 3 cases at C4, 5 cases at C5, 5 cases at C6, and 3 cases at C7. The X-ray films showed a typical "palisade" change. According to the clinical and imaging features, there were 13 cases of type II and 5 cases of type IV of cervical hemangioma. The standard anterior cervical decompression and fusion with internal fixation were performed and then percutaneous vertebroplasty (PVP) was used. The cervical X-ray films were taken to observe bone cement distribution and the internal fixation after operation. The recovery of neurological function and the neck pain relief were measured by Japanese Orthopaedic Association (JOA) score and visual analogue scale (VAS) score. All operations were successful with no spinal cord and nerves injury, and the incisions healed well. Anterior bone cement leakage occurred in 2 cases without any symptoms. All cases were followed up 24-28 months (mean, 26 months) and the symptoms were improved at different degrees without fracture and collapse of vertebra or recurrence of hemangioma. During the follow-up, there was no implant loosening, breakage and displacement, and the mean fusion time was 4 months (range, 3-4.5 months). The JOA score and VAS score had a significant recovery at 3 months and at last follow-up when compared with preoperative values (P < 0.05). Based on JOA score at last follow-up, the results were excellent in 9 cases, good in 6 cases, fair in 2 cases, and poor in 1 case. The anterior cervical decompression and fusion with internal fixation combined with PVP treatment is one of the ideal ways to treat symptomatic cervical vertebral hemangioma associated with cervical spondylotic myelopathy, which could completely decompress the spinal cord and effectively alleviate the clinical symptoms caused by vertebral hemangioma.

We report the interim results from XCiDaBLE, a large, prospective, observational "naturalistic" study evaluating Xeomin® (incobotulinumtoxinA) for Cervical Dystonia or BLEpharospasm in the United States. Subjects (≥ 18 years old) with cervical dystonia (CD) are followed for two treatment cycles and monitored via Interactive Voice/Web Response. The subject's physician must have chosen to treat with incobotulinumtoxinA prior to and independent of enrollment in this study. Subject-reported scales include the Subject Global Impression-Severity and Improvement and Cervical Dystonia Impact Profile (CDIP-58), and Work Productivity and Quality of Life (QoL) are assessed by means of an employment questionnaire and work history and the SF-12v2 Health Survey (SF-12v2). Subjects are seen by the investigator for three visits, which include a baseline visit (including the first injection), a second injection visit, and a final study visit (12 weeks after the second injection). This ongoing study includes 145 subjects with a diagnosis of CD. The majority were female (82.3%) and white (91.0%) and had previously been treated with botulinum toxins (77.2%). There were 106 employed at the time of disease onset, but 12.6 years later only 44% were still employed at the time of enrolment into the study, and 20% were either receiving or seeking disability benefits. The mean total dose/treatment of CD was 225.2 units for the first injection. The CDIP-58 total score was significantly improved 4 weeks after the first injection compared to baseline (p≤0.0001). Most subjects noted improvement in their global impression assessment. No new or unexpected adverse events occurred. The results from these interim analyses confirm previous controlled, single-dose studies of incobotulinumtoxinA in terms of efficacy and safety.

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

PubMed

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.

The stand-alone treatment of degenerative cervical spine pathologies is a proven method in clinical practice. However, its impact on subsidence, the resulting changes to the profile of the cervical spine and the possible influence of clinical results compared to treatment with additive plate osteosynthesis remain under discussion until present. This study was designed as a retrospective observational cohort study to test the hypothesis that radiographic subsidence of cervical cages is not associated with adverse clinical outcomes. 33 cervical segments were treated surgically by ACDF with stand-alone cage in 17 patients (11 female, 6 male), mean age 56 years (33-82 years), and re-examined after eight and twenty-six months (mean) by means of radiology and score assessment (Medical Outcomes Study Short Form (MOS-SF 36), Oswestry Neck Disability Index (ONDI), painDETECT questionnaire and the visual analogue scale (VAS)). Subsidence was observed in 50.5% of segments (18/33) and 70.6% of patients (12/17). 36.3% of cases of subsidence (12/33) were observed after eight months during mean time of follow-up 1. After 26 months during mean time of follow-up 2, full radiographic fusion was seen in 100%. MOS-SF 36, ONDI and VAS did not show any significant difference between cases with and without subsidence in the two-sample t-test. Only in one type of scoring (painDETECT questionnaire) did a statistically significant difference in t-Test emerge between the two groups (p = 0.03; α = 0.05). However, preoperative painDETECT score differ significantly between patients with subsidence (13.3 falling to 12.6) and patients without subsidence (7.8 dropped to 6.3). The radiological findings indicated 100% healing after stand-alone treatment with ACDF. Subsidence occurred in 50% of the segments treated. No impact on the clinical results was detected in the medium-term study period.

Background Cervical intraepithelial neoplasia (CIN) is the most common pre-malignant lesion. Atypical squamous changes occur in the transformation zone of the cervix with mild, moderate or severe changes described by their depth (CIN 1, 2 or 3). Cervical intraepithelial neoplasia is treated by local ablation or lower morbidity excision techniques. Choice of treatment depends on the grade and extent of the disease. Objectives To assess the effectiveness and safety of alternative surgical treatments for CIN. Search methods We searched the Cochrane Gynaecological Cancer Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE and EMBASE (up to April 2009). We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of included studies. Selection criteria Randomised controlled trials (RCTs) of alternative surgical treatments in women with cervical intraepithelial neoplasia. Data collection and analysis Two review authors independently abstracted data and assessed risks of bias. Risk ratios that compared residual disease after the follow-up examination and adverse events in women who received one of either laser ablation, laser conisation, large loop excision of the transformation zone (LLETZ), knife conisation or cryotherapy were pooled in random-effects model meta-analyses. Main results Twenty-nine trials were included. Seven surgical techniques were tested in various comparisons. No significant differences in treatment failures were demonstrated in terms of persistent disease after treatment. Large loop excision of the transformation zone appeared to provide the most reliable specimens for histology with the least morbidity. Morbidity was lower than with laser conisation, although the trials did not provide data for every outcome measure. There were not enough data to assess the effect on morbidity when compared with laser ablation. Authors’ conclusions The evidence suggests that there is no obvious superior surgical technique for treating cervical intraepithelial neoplasia in terms of treatment failures or operative morbidity.

Background Cervical drains have historically been used to avoid postoperative wound and respiratory complications such as excessive edema, hematoma, infection, re-intubation, delayed extubation, or respiratory distress. Recently, some surgeons have ceased using drains because they may prolong hospital stay, operative time, or patient discomfort. The objective of this retrospective case-control series is to investigate the effectiveness of postoperative drains following one- and two-level cervical fusions. Methods A chart review was conducted at a single institution from 2010-2013. Outcome measures included operative time, hospital stay, estimated blood loss and incidence of wound complications (infection, hematoma, edema, and complications with wound healing or evacuation), respiratory complications (delayed extubation, re-intubation, and respiratory treatment), and overall complications (wound complications, respiratory complications, dysphagia, and other complications). Statistical analyses including independent samples t-test, chi-square, analysis of covariance, and linear regression were used to compare patients who received a postoperative drain to those who did not. Results The study population included 39 patients who received a postoperative drain and 42 patients who did not. There were no differences in demographics between the two groups. Patients with drains showed increased operative time (100.1 vs 69.3 min, p < 0.001), hospital stay (38.9 vs. 31.7 hrs, p = 0.021), and blood loss (62.7 vs 29.1 mL, p < 0.001) compared to patients without drains. The frequency of wound complications, respiratory complications, and overall complications did not vary significantly between groups. Conclusions/Level of Evidence Cervical drains may not be necessary for patients undergoing one- and two-level cervical fusion. While there were no differences in incidence of complications between groups, patients treated with drains had significantly longer operative time and length of hospital stay. Clinical relevance This could contribute to excessive costs for patients treated with drains, despite the lack of compelling evidence of the advantages of this treatment in the literature and in the current study.

Cervical spinal cord injury (SCI) is a devastating event for the patient and family. It has a huge impact on society because of the intensive resources required to manage the patient in both the acute and rehabilitation phases. Given the resource-limited setting in South Africa, questions are often raised regarding whether the outcome of this group of patients justifies the expense of their care. However local data have not been available to date. To evaluate the mortality, morbidity and functional outcome of cervical SCI patients in the South African environment. All cervical SCI patients managed in the acute spinal cord injury unit at Groote Schuur Hospital over a 12-month period were included. Epidemiological data, management, complications, neurological status and change were assessed. Those referred for rehabilitation were followed up in terms of mortality and ambulation status. There were 101 patients, with an average age of 34.7 years. Motor vehicle accidents were the commonest cause of injury, with violence contributing 21%. Fifty-nine patients required referral to a rehabilitation unit. Of these, 18 were functional walkers, and only 6 were care-dependent. By 1 year post injury all but 1 patient had been discharged from the health service. Fourteen patients died; in half of these cases injury was at C5 level and above. Despite cervical SCI being a devastating event, aggressive early intervention yields a better-than-expected 1-year survival rate. Associated problems, such as pressure sores, remain a major problem both for the patient and in terms of health care costs. It is difficult to predict prognosis on presentation because of spinal shock. It is recommended that all patients initially be treated aggressively, with exit strategies in place once all the information is available and a confident assessment of poor prognosis can be made.

 Anterior cervical fusion (ACF) with autologous bone was reported > 50 years ago. The continuous development of materials with elastic properties close to that of the cortical bone improves induction of osteogenesis and simplifies the technique of interbody fusion. To determine the safety and efficiency of stand-alone trabecular metal (TM) (or porous tantalum) cages for ACF, we performed a retrospective analysis of 88 consecutive patients with one-level or two-level degenerative disk disease (DDD) causing cervical myelopathy treated by interbody fusion with stand-alone TM cages.  During a 65-month period, 88 consecutive patients had ACF at 105 levels between C3 and C7. All surgeries involved one- or two-segmental DDD producing mild or severe cervical spine myelopathy, in 31 patients (35.2%), associated with unilateral or bilateral radiculopathy. We implanted all disk spaces with unfilled TM trapezoidal cages (Zimmer Biomet Spine, Broomfield, Colorado, United States).  At a mean follow-up of 31 months (range: 12-65 months), 95.4% of patients had a good to excellent outcome, with subjective and objective improvement of myelopathy; the result was fair in two and poor in two other patients. Radicular pain and/or any deficits disappeared in 84 patients (95.4%) complaining of preoperative myeloradiculopathy. The fusion rate was 68.2% at 6 months and 100% at 1 year. Device fragmentation was never observed. In two cases, a second operation with removal of TM cages, corpectomy, expansion cages, and plating was necessary.  TM cages appear to be safe and efficient for ACF in DDD patients with myelopathy. To confirm our preliminary impressions, larger studies with long-term follow-up are necessary. Georg Thieme Verlag KG Stuttgart · New York.

Hypothyroidism is a common complication when radiotherapy is part of the treatment for head and neck tumours. This study aimed to show the incidence of hypothyroidism and possible risk factors in these patients. Factors related to the population, tumour, treatment and occurrence of hypothyroidism were analysed in 241 patients diagnosed with head and neck carcinoma. Approximately 53 per cent of patients were diagnosed with radiation-induced hypothyroidism. Its occurrence was related to: tumour location, laryngeal surgery type, neck dissection type, post-operative complications, cervical radiotherapy and radiotherapy unit type (linear particle accelerator or telecobalt therapy technology). Control of thyroid function should be standardised for several years after treatment, particularly in patients with risk factors, such as those treated with telecobalt therapy, those with post-operative complications and for whom the thyroid parenchyma is included in the irradiated area (laryngeal or pharyngeal location and bilateral cervical radiation).

Cervical vertebral (C) malformation is rarely reported in large breed dogs. Congenital cervical kyphosis (CCK) may result from defects of vertebral segmentation, failure of formation or both. This report describes two cases of C3-C4 CCK in young sighthounds, treated surgically. An 18-month-old female Deerhound and a six-week-old female Borzoi dog were presented because of the complaints of reluctance to exercise and signs of of neck pain. Both dogs were neurologically normal. Diagnostic imaging revealed C3-C4 deformity, moderate kyphosis, and spinal canal stenosis associated with chronic spinal cord pressure atrophy. Both dogs underwent surgical treatment. A staged two-step surgery starting with dorsal decompression was elected in the Deerhound. After the first surgical procedure, the dog developed focal myelomalacia and phrenic nerve paralysis and was euthanatized. A ventral distraction-fusion technique with two locking plates was performed in the Borzoi. This patient recovered uneventfully and long-term follow-up computed tomography revealed complete spondylodesis. Until now, CCK has only been described in sighthounds. Congenital cervical kyphosis might be considered a differential diagnosis in these breeds that are presented with signs of cervical pain. Ventral realignment-fusion and bone grafting may be considered for surgical treatment, although the earliest age at which this procedure can and should be performed remains unclear.

Low physician density, undercapacitated laboratory infrastructures, and limited resources are major limitations to the development and implementation of widely accessible cervical cancer prevention programs in sub-Saharan Africa. We developed a system operated by nonphysician health providers that used widely available and affordable communication technology to create locally adaptable and sustainable public sector cervical cancer prevention program in Zambia, one of the world's poorest countries. Nurses were trained to perform visual inspection with acetic acid aided by digital cervicography using predefined criteria. Electronic digital images (cervigrams) were reviewed with patients, and distance consultation was sought as necessary. Same-visit cryotherapy or referral for further evaluation by a gynecologist was offered. The Zambian system of "electronic cervical cancer control" bypasses many of the historic barriers to the delivery of preventive health care to women in low-resource environments while facilitating monitoring, evaluation, and continued education of primary health care providers, patient education, and medical records documentation. The electronic cervical cancer control system uses appropriate technology to bridge the gap between screening and diagnosis, thereby facilitating the conduct of "screen-and-treat" programs. The inherent flexibility of the system lends itself to the integration with future infrastructures using rapid molecular human papillomavirus-based screening approaches and wireless telemedicine communications.

The clinical significance of determining sentinel lymph nodes (SLN) in patients with invasive cervical cancer was studied. From 2013 to 2014, 30 cervical cancer patients (T1a1NxM0-T1b1NxM0) were treated at the Gynecological Oncology Department of the Cancer Research Institute. The day before surgery, four submucosal injections of 99mTc Al2O3 at a total dose of 80 MBq were made in each quadrant around the cervical tumor. Patients were submitted to preoperative lymphoscintigraphy and intraoperative SLN detection. The feasibility of preserving the reproductive potential in patients after radical abdominal trachelectomy was assessed. The 3-year, overall, disease-free and metastasis-free survival rates were analyzed. Thirty-four SLNs were detected by single-photon emission computed tomography (SPECT) and 42 SLNs were identified by intraoperative gamma probe. The sensitivity in detecting SLNs was 100% for intraoperative SLN identification and 80% for SPECT image. The reproductive potential was preserved in 86% of patients. The 3-year overall and metastases-free survival rates were 100%. Recurrence occurred in 8.6% of cases.

Branchial cleft or cervical lymphoepithelial cysts: etiology and management.

PubMed

Glosser, Jeffrey W; Pires, Carlos Alberto S; Feinberg, Stephen E

2003-01-01

The cervical lymphoepithelial or branchial cleft cyst is a developmental cyst that has a disputed pathogenesis. The objective of this article is to provide a brief review of the literature and to define diagnostic terms related to this anomaly, as well as to describe its etiology, clinical presentation and treatment. The cervical lymphoepithelial or branchial cleft cyst usually presents as a unilateral, soft-tissue fluctuant swelling that typically appears in the lateral aspect of the neck, anterior to the sternocleidomastoid muscle, and becomes clinically evident late in childhood or in early adulthood. Clinicians can diagnose the cyst with appropriate imaging to assess the extent of the lesion before definitive surgical treatment. The authors describe a patient who underwent excision of a well-encapsulated cystic structure that was diagnosed as a branchial cleft cyst. The cervical lymphoepithelial or branchial cleft cyst can be easily misdiagnosed as a parotid swelling or odontogenic infection. It is imperative that clinicians make an accurate diagnosis so that appropriate treatment (that is, surgical excision) can be performed. If the cysts are treated properly, recurrences are rare.

Persistent HPV infection is a necessary condition for the occurrence of cervical cancer. Prophylactic HPV vaccines have been developed to reduce the incidence of cervical cancer. Two vaccines are commercially available: bivalent (types 16, 18) and quadrivalent (6, 11, 16 and 18). This study aimed to perform a systematic review and metaanalysis of the HPV vaccines' efficacy in women, focusing its performance stratified by clinical outcomes. Randomized controlled trials (RCT) published between 2000 and 2009 were identified from searches of MEDLINE, LILACS and Cochrane Library, and evaluated by two independent reviewers. Six RCT were selected. The vaccines reduced the risk of precursor lesions of cervical cancer, presenting efficacy of 97% (95%CI: 90-99) for CIN 2 and 96% (95%CI: 89-99) for CIN 3, in the per protocol analysis. The efficacies in the analysis by intention to treat were smaller: 63% (95%CI: 52-71) and 42% (95%CI: 26-55), respectively. In order to evaluate its effectiveness on the incidence and mortality rates for cervical cancer, longer-term studies will be needed.

In an open randomized clinical trial 100 pregnant women with low Bishop Scores at term were treated either with intracervical Prostaglandin (PG) E2 (0.5 mg in 2.5 ml triacetin-gel) 12 hours before labor induction with intravenous oxytocin or with oxytocin infusion alone. In 46 of the 50 pretreated patients (92%) the Bishop Score progressed at least 3 points, in four cases only 2 points. The mean Bishop score in the untreated patients increased insignificantly. After PGE2-gel administration 16 patients delivered during the 12 hour interval compared to 3 in the group without pretreatment. The first induction attempt was successful in 14 (64%) of the 22 patients that were left to be induced after cervical softening and in 26 (57%) of the 47 women without cervical priming. The Cesarean section rate was 10% (n = 5) in the PGE2-gel group and 12% (n = 6) in the control group. Dosage of oxytocin required for labor induction was significantly lower after cervical softening. No serious fetal or maternal side effects were observed after PGE2 pretreatment.

To explore current practice in fertility-sparing surgery for cervical cancer in the UK. A web-based structured questionnaire was designed and circulated to all members of the British Gynaecological Cancer Society. From 111 recipients, a total of 49 responses were collected. The majority of centres treated between 20-29 cases of invasive cervical cancer surgically (21/49, 42.9%) and performed between 0-5 cases of radical trachelectomy annually (29/49, 59.2%). The vaginal approach was the one most commonly used and was offered by almost half of the centres (21/49, 42.9%); laparoscopic techniques were offered in 13 (13/49, 26.6%). The responses were divided as to whether these cases should have been referred to supra-regional centres (25/49, 51.0%). With the use of Human Papillomavirus vaccination leading to a projected decrease in the number of cervical cancer incidence, patients may need to be referred to supraregional centres in the future.

Between 1994 and 1999, 837 flexion-extension cervical spine films (F/E) were ordered as part of a protocol to evaluate cervical stability in blunt trauma victims, particularly obtunded patients with otherwise normal films. After 5 years' experience with this protocol, a review of its efficiency and cost-effectiveness was performed. The radiology reports and charts were reviewed for positive or suggestive F/E series. Nearly a third of all series were inadequate to rule out instability. Only four patients were identified who had decreased admission Glasgow Coma Scale score, normal plain films and/or CT, and positive or suggestive findings on F/E. One was felt to be a false positive, and the others had minor or borderline findings; all were treated with continuation of the cervical collar. Although one patient was lost to follow-up, none of the other three required subsequent surgery or developed deformity or neurologic injury. Flexion-extension studies were not a cost-effective part of the protocol, and they were dropped.

The occurrence of radiological mediastinal lymphadenopathy as the only evidence of tumor recurrence of cervical carcinoma is very rare. We report on such a case with stenosis of the esophagus. A 36-year-old Caucasian woman, without any relevant history of gynecological cancer, underwent a trans-vaginal ultrasound with evidence of any cervical lesion locally extended. After histologically-proven diagnosis of squamous cell carcinoma of the cervix uterine, the patient was treated by neoadjuvant chemoradiation, followed by total abdominal hysterectomy with bilateral salpingoophorectomy. A subsequent close follow-up was negative for recurrence of disease until December 2008, two years after diagnosis. At that period, the patient experienced cough and severe dysphagia and for this reason she underwent several examinations including esophagogastroduodenoscopy, whole-body computed tomographic scan and bronchoscopy with transbronchial needle aspiration. Histology led to diagnosis of recurrence of cervical cancer, HPV31-positive, in multiple mediastinal lymphnodes, with infiltration of the esophageal mucosa. Mediastinal lymphade-nopathy in patients with a history of cervical carcinoma should be suspicious of metastatic disease, even if there is no radiological evidence of distant metastases.

IκB kinase b Mediating the Downregulation of p53 and p21 by Lipopolysaccharide in Human Papillomavirus 16+ Cervical Cancer Cells.

Cervical cancer is the second most common cancer of woman in the world, and human papillomavirus (HPV) infection plays an important role in the development of most of the cases. IκB kinase β (IKKβ) is a kinase-mediating nuclear factor kappa B (NF-κB) activation by phosphorylating the inhibitor of NF-κB (IκB) and is related by some diseases caused by virus infection. However, there is little known about the correlation between IKKβ and HPV infection in cervical cancer. This study aimed to investigate the expression of IKKβ protein in cervical cancer tissues and effects of inflammation on HPV positive or negative cervical cancer cells through detecting the expression of IKKβ, IκBα, p53, and p21 proteins after treated with lipopolysaccharide (LPS) to mimic bacterial infection. We also examined the effects of LPS on cervical cancer cells after blocking IKKβ with pharmacological inhibitor. Thirty-six matched specimens of cervical cancer and adjacent normal tissues were collected and analyzed in the study. The expression of IKKβ in the tissue specimens was determined by immunohistochemical staining. In addition, Western blot was used to detect the expression level changes of IKKβ, IκBα, p53, and p21 after LPS stimulated in the HPV16+ (SiHa) and HPV16- (C33A) cervical cancer cell lines. Furthermore, the effects of IKKβ inhibitor SC-514 on LPS-induced expression change of these proteins were investigated. The expression of IKKβ was higher in cervical cancer than adjacent normal tissues, and there was no significant difference between tumor differentiation, size, and invasive depth with IKKβ expression. The LPS, which increased the expression level of IKKβ protein but decreased in the IκBα, p53 and p21 proteins, was illustrated in HPV16+ (SiHa) but not in HPV16- (C33A) cells. Moreover, IKKβ inhibitor SC-514 totally reversed the upregulation of IKKβ and downregulation of p53 and p21 by LPS in SiHa cells. IKKβ may mediate the downregulation of p53 and p21 by LPS in HPV16+ cervical cancer cells.

Cervical spine injury may present with pediatric patients having sustained fractures of the craniofacial skeleton. Management considerations of the cervical spine often take priority to the fractures of the facial skeleton. The goal of this study was to examine this subset of patients with a focus on initial presentation and need for intervention. A retrospective review from 2000 to 2012 of all facial fractures in patients ≤ 18 years at a level 1 trauma center was performed. Patient demographics, location of fractures, and the presence of a cervical spine injury were collected. During this time period, 285 patients met inclusion criteria. Ten patients were found to have a cervical spine injury. Fractures of the zygoma and orbit were significantly associated with a cervical spine injury. Patients with a cervical spine injury had a Glasgow Coma Scale of 11.2 compared with 13.8 in those without (P < 0.05). C1 was injured in 4 patients, C2 in 2 patients, and C3 to C7 in 4 patients. A surgical airway was required in 1 patient, and 6 were intubated in the trauma bay. Fractures of the mandible were significantly associated with injury to C2. Le Fort fractures and palate fractures approached significance with injury to C1. Only 1 patient had neurologic impairment at presentation, manifested as upper extremity parasthesias, and underwent decompression and fusion in the operating room. Those patients admitted (90%) were all admitted for reasons other than management of the cervical spine injury. The majority of patients (70%) were treated with collar immobilization. One patient expired. No patients had a neurologic deficit at the time of discharge. In this study only 1 cervical spine injury necessitated intervention, with an eventual full recovery. Cervical spine injuries presenting with fractures of the facial skeleton appear to be relatively benign in this series; however, care must be taken to identify all such injuries to avoid exacerbation during maneuvers commonly used for facial fracture treatment. Special caution should be used when examining patients with a depressed Glasgow Coma Scale or in those with upper midface fractures.

A retrospective 1-year cost-utility analysis. To determine the cost-effectiveness of anterior cervical discectomy and fusion with plating (ACDFP) in comparison with posterior cervical foraminotomy (PCF) for patients with single-level cervical radiculopathy. Cervical radiculopathy due to cervical spondylosis is commonly treated by either PCF or ACDFP for patients who are refractory to nonsurgical treatment. Although some have suggested superior outcomes with ACDFP as compared with PCF, the former is also associated with greater costs. The present study analyzes the cost-effectiveness of ACDFP versus PCF for patients with single-level cervical radiculopathy. Forty-five patients who underwent ACDFP and 25 patients who underwent PCF for single-level cervical radiculopathy were analyzed. One-year postoperative health outcomes were assessed based on Visual Analogue Scale, Pain Disability Questionnaire, Patient Health Questionnaire, and EuroQOL-5 Dimensions questionnaires to analyze the comparative effectiveness of each procedure. Direct medical costs were estimated using Medicare national payment amounts and indirect costs were based on patient missed work days and patient income. Postoperative 1-year cost/utility ratios and the incremental cost-effectiveness ratio (ICER) were calculated to assess for cost-effectiveness using a threshold of $100,000/QALY gained. The 1-year cost-utility ratio for the PCF cohort was significantly lower ($79,856/QALY gained) than that for the ACDFP cohort ($131,951/QALY gained) (P<0.01). In calculating the 1-year ICER, as the ACDFP cohort showed lower QALY gained than the PCF cohort, the ICER was negative and is not reported, meaning that ACDFP was dominated by PCF. Statistically significant and clinically relevant improvements (through minimum clinically important differences) were seen in both cohorts. Although both cohorts showed improved health outcomes, ACDFP was not cost-effective relative to the threshold of $100,000/QALY gained at 1-year postoperatively, whereas PCF was. The durability of these results must be analyzed with long-term cost-utility analysis studies.

To date, no study had reported the phenomenon of deteriorated postoperative cervical tilt in Lenke type 2 adolescent idiopathic scoliosis patients. The purpose of this study is to evaluate the cervical tilt in Lenke type 2 adolescent idiopathic scoliosis patients with right-elevated shoulder treated by either full fusion or partial/non fusion of the proximal thoracic curve. A total of 30 Lenke type 2 AIS patients with preoperative right-elevated shoulder underwent posterior spinal instrumentation from 2009 to 2011 were included in this study. All the subjects were divided into 2 groups according to the selection of upper instrumented vertebra. There were 14 cases proximally fused to T1 or T2 (Group A) and 16 cases proximally fused to T3 or below (Group B). Both standing anteroposterior and sagittal X-ray films of the spine obtained preoperatively, one week after the operation, and at a minimum of two-year follow-up were analyzed with respect to the following parameters: cervical tilt, T1 tilt, proximal thoracic Cobb angle, main thoracic Cobb angle, apical vertebral translation of proximal thoracic curve, apical vertebral translation of main thoracic curve, radiographic shoulder height, cervical lordosis, proximal thoracic kyphosis and main thoracic kyphosis. Most (83.3%) of the patients in these two groups gained satisfactory shoulder balance after surgery. However, the cervical tilt significantly improved in group A (p < 0.001) but deteriorated in group B (p < 0.001). In group A, the decrease of cervical tilt significantly positively correlated with that of T1 tilt (p < 0.001). In group B, the increase of cervical tilt significantly positively correlated with both the increase of T1 tilt (p < 0.001) and the increase of apical vertebral translation of proximal thoracic curve (p < 0.05). Lenke type 2 AIS patients with right-elevated shoulder gain improved shoulder but deteriorated cervical tilt after partial/non fusion of proximal thoracic curve. Full fusion of proximal thoracic curve helps to prevent the residual cervical tilt in these patients.

A retrospective database review. The aim of this study was to determine readmission reasons and rates following primary, elective anterior cervical spinal fusion surgery for cervical spondylosis and determine risk factors predicting increased risk of 30-day readmission in an exclusively elderly population. In the United States, there were almost 190,000 cervical spine procedures in 2009. Many cervical spine surgery patients are elderly, a demographic increasingly requiring surgery for degenerative cervical spine pathology. Unfortunately, this patient population is poorly studied, particularly concerning readmission rates. Medicare data from 2005 to 2012 were queried for elderly patients (65-84 years) who underwent primary one to two and ≥three-level anterior cervical spine fusion surgeries for cervical spondylosis. Forty-five thousand two hundred eighty-four patients treated with one to two-level and 12,103 patients with ≥three-level anterior cervical fusion (ACF) were identified and included in two study cohorts. Reasons for and rates of readmission were determined within 30 days, 90 days, and one-year postoperatively. Risk factors for medical, surgical, and all 30-day readmissions were also determined, selecting from various comorbidities, demographics, and surgical variables. Readmission rates of 1.0% to 1.4%, 2.7% to 3.6%, and 13.2% to 14.1% were observed within 30 days, 90 days, and one year. Within 30 days, over 30% of patients from both study cohorts were readmitted for surgical reasons. Of surgical reasons for 30-day readmission, hematoma/seroma diagnoses were the most frequent (11.4%-15.4% of all readmissions). Male gender, diabetes mellitus, chronic pulmonary disease, obesity, and smoking history were all found to be predictive of all-cause readmissions. Unplanned 30-day readmission rates following primary, elective ACF in elderly patients is low and often due to medical reasons. Frequent surgical reasons for 30-day readmission include hematoma/seroma formation. Male gender and various comorbid diagnoses are significant predictors of all-cause readmissions within 30 days. 3.

To explore serial reconstruction strategy for severe cervical cicatrix deformity. A total of 24 cases, III or IV degree cervical contracture deformity, were treated in Shanghai Ninth People's Hospital from January 2006 to December 2011. There were 18 males and 6 females with an average age of 35.4 years. The etiologies included burns, chemical injuries and scalding. Three evaluation indices of mental cervical angle (MCA) including soft tissue MCA, osseous MCA and dynamic MCA were measured before treatment and during follow-ups. The first-stage treatment was comprised of cervical cicatrix resection, contracture release, lift of dual direction platysma flap, reconstruction of MCA and skin grafting. At Months 3-6, second-stage treatment was performed, including lower mandible scar resection, correction of lower lip eversion, lower mandible region reconstruction with free (para-) scapular skin flap. After two-stage treatment, the patients underwent periodical re-evaluations for gross appearance, function and measurement of MCA. Twenty-two patients completing two-stage reconstruction were followed up. Notable improvement of cervical mobilization and contour were achieved. Soft tissue MCA decreased from 130° ± 34° to 110° ± 24°, osseous MCA increased from 71° ± 23° to 95° ± 19° and dynamic MCA increased from 25° ± 18° to 80° ± 26°. The serial treatment strategy is effective. In comparisons with reconstruction with skin graft only or skin flap only, the strategy possesses many advantages.

Prospective, randomized, single-center, clinical trial. To prospectively examine the 7- and 10-year outcomes of cervical arthroplasty to anterior cervical discectomy and fusion (ACDF). Degeneration of the cervical discs causing radiculopathy is a frequent source of surgical intervention, commonly treated with ACDF. Positive clinical outcomes are associated with arthrodesis techniques, yet there remains a long-term concern for adjacent segment change. Cervical disc arthroplasty has been designed to mitigate some of the challenges associated with arthrodesis whereas providing for a similar positive neurological outcome. As data has been collected from numerous prospective US FDA IDE trials, longer term outcomes regarding adjacent segment change may be examined. As part of an FDA IDE trial, a single center collected prospective outcomes data on 47 patients randomized in a 1:1 ratio to ACDF or arthroplasty. Success of both surgical interventions remained high at the 10-year interval. Both arthrodesis and arthroplasty demonstrated statistically significant improvements in neck disability index, visual analog scale neck and arm pain scores at all intervals including 7- and 10-year periods. Arthroplasty demonstrated an advantage in comparison to arthrodesis as measured by final 10-year NDI score (8 vs. 16, P = 0.0485). Patients requiring reoperation were higher in number in the arthrodesis cohort (32%) in comparison with arthroplasty (9%) (P = 0.055). At 7 and 10 years, cervical arthroplasty compares favorably with ACDF as defined by standard outcomes scores in a highly selected population with radiculopathy. 1.

Women diagnosed with invasive cervical carcinoma during pregnancy are faced with difficult decisions regarding therapy and the fate of their unborn child. A modest treatment delay for International Federation of Gynecology and Obstetrics Stage I cervical lesions is considered acceptable in patients who wish to continue their pregnancy. Two patients with locally advanced cervical carcinoma diagnosed early in the second trimester strongly desired continuation of their pregnancies. They were treated with neoadjuvant chemotherapy until the third trimester, and then underwent delivery and definitive surgical treatment. The patients were evaluated during pregnancy for evidence of a clinical response to chemotherapy. Intraoperative findings and pathologic analysis of the surgical material provided further objective data regarding disease status. Both patients experienced a dramatic reduction in tumor volume, rendering radical hysterectomy feasible at the time of cesarean section. In addition, both patients tolerated chemotherapy well and there were no adverse fetal effects. Favorable neonatal outcomes were achieved. One patient experienced recurrence within 5 months of surgery, whereas the other patient remained without evidence of disease for 2 years. To the authors' knowledge, these reports constitute the first description of the use of neoadjuvant chemotherapy for invasive squamous cell carcinoma of the cervix in pregnancy (MEDLINE 1966-1997). This therapeutic option should be considered in selected women with locally advanced cervical carcinoma who do not want termination of their pregnancy.

Early fixation of type II odontoid fractures has been shown to provide high rates of long-term stabilization and osteosynthesis. In this report, the authors present the case of a patient with a locked type II odontoid fracture treated by anterior screw fixation facilitated by closed transoral and posterior cervical manual reduction. While transoral intraoperative reduction of a partially displaced odontoid fracture has previously been described, the authors present the first case utilizing this technique in the treatment of a completely dislocated type II odontoid fracture.

Sixty-five patients with cervical spine injuries and varied neurological deficits were treated operatively. Evaluation revealed an improvement in neurological findings dependent upon the promptness of anatomical reduction in patients with incomplete lesions. The more frequent neurological improvement seen with open reduction and internal fixation as compared with closed reduction was not statistically significant but was felt to justify the additional resources required for internal fixation. In complete lesions, there was no evidence that the time of anatomical reduction was related to improvement in neurological findings.

There are several methods of treating cervical dysplasia, including surgical and electric conisation, laservaporisation. The aim of our study was to evaluate leep-loop method and laservaporisation wtih CO2 laser. Material consisted of 49 women, 28 underwent leep-loop conisation and 21 lavervaporisation. The effectiveness of laser treatment was 90,4% and with leep-loop 96,4%, but the difference was not statistically significant. Mean time of wound healing and frequency of pain was shorter after laser treatment, but the differences were not statistically significant. Conclusions: Effect treatment with both methods is comparable.

Acute whiplash injuries are a common cause of soft tissue trauma for which the standard treatment is rest and initial immobilisation with a soft cervical collar. Because the efficacy of this treatment is unknown a randomised study in 61 patients was carried out comparing the standard treatment with an alternative regimen of early active mobilisation. Results showed that eight weeks after the accident the degree of improvement seen in the actively treated group compared with the group given standard treatment was significantly greater for both cervical movement (p less than 0.05) and intensity of pain (p less than 0.0125).

Management of cervical lymph nodes metastases of squamous cell carcinoma (SCC) from primary of unknown origin (PUO) is contentious and there is insignificant data from India on this subject. To present experience of management of these patients treated with curative intent at a single institution. Retrospective study of patients treated between 1989-1994 in a tertiary referral cancer centre. Eighty-nine patients were evaluated in the study period and their survival compared with patients with common sites of primary in the head and neck with comparable node stage. Kaplan-Meier method. The clinical stage of the neck nodes at presentation was N1 in 11%, N2a in 28.5%, N2b in 22.5%, N3 in 35% and Nx in 3.4% patients. All patients underwent surgery and 70 patients received more than 40Gy postoperative radiotherapy. Twenty-nine (32.6%) patients had relapse of which 19 (21%) were in the neck. Postoperative radiotherapy did not influence the neck relapse (p=0.72). Primary was detected in 13 patients (14.6%) on subsequent follow up. The overall five and eight-years survival was 55% and 51% respectively. The overall five-year survival was better compared to patients with known primary with comparable node stage. Patients with cervical lymph nodes metastases of SCC from PUO have reasonable survival and low rate of development of subsequent primary when treated with surgery and radiotherapy. The overall survival is comparable to that of patients with known primary and hence an attempt at cure should always be made.

BACKGROUND Human papillomavirus (HPV) vaccines prevent HPV infection and cervical precancers. The impact of vaccinating women with a current infection or after treatment for an HPV-associated lesion is not fully understood. OBJECTIVES To determine whether HPV-16/18 vaccination influences the outcome of infections present at vaccination and the rate of infection and disease after treatment of lesions. STUDY DESIGN We included 1711 women (18–25 years) with carcinogenic human papillomavirus infection and 311 women of similar age who underwent treatment for cervical precancer and who participated in a community-based trial of the AS04-adjuvanted HPV-16/18 virus-like particle vaccine. Participants were randomized (human papillomavirus or hepatitis A vaccine) and offered 3 vaccinations over 6 months. Follow-up included annual visits (more frequently if clinically indicated), referral to colposcopy of high-grade and persistent low-grade lesions, treatment by loop electrosurgical excisional procedure when clinically indicated, and cytologic and virologic follow-up after treatment. Among women with human papillomavirus infection at the time of vaccination, we considered type-specific viral clearance, and development of cytologic (squamous intraepithelial lesions) and histologic (cervical intraepithelial neoplasia) lesions. Among treated women, we considered single-time and persistent human papillomavirus infection, squamous intraepithelial lesions, and cervical intraepithelial neoplasia 2+. Outcomes associated with infections absent before treatment also were evaluated. Infection-level analyses were performed and vaccine efficacy estimated. RESULTS Median follow-up was 56.7 months (women with human papillomavirus infection) and 27.3 months (treated women). There was no evidence of vaccine efficacy to increase clearance of human papillomavirus infections or decrease incidence of cytologic/histologic abnormalities associated with human papillomavirus types present at enrollment. Vaccine efficacy for human papillomavirus 16/18 clearance and against human papillomavirus 16/18 progression from infection to cervical intraepithelial neoplasia 2+ were −5.4% (95% confidence interval −19,10) and 0.3% (95% confidence interval −69,41), respectively. Among treated women, 34.1% had oncogenic infection and 1.6% had cervical intraepithelial neoplasia 2+ detected after treatment, respectively, and of these 69.8% and 20.0% were the result of new infections. We observed no significant effect of vaccination on rates of infection/lesions after treatment. Vaccine efficacy estimates for human papillomavirus 16/18 associated persistent infection and cervical intraepithelial neoplasia 2+ after treatment were 34.7% (95% confidence interval −131, 82) and −211% (95% confidence interval −2901, 68), respectively. We observed evidence for a partial and nonsignificant protective effect of vaccination against new infections absent before treatment. For incident human papillomavirus 16/18, human papillomavirus 31/33/45, and oncogenic human papillomavirus infections post-treatment, vaccine efficacy estimates were 57.9% (95% confidence interval −44, 88), 72.9% (95% confidence interval 29, 90), and 36.7% (95% confidence interval 1.5, 59), respectively. CONCLUSION We find no evidence for a vaccine effect on the fate of detectable human papillomavirus infections. We show that vaccination does not protect against infections/lesions after treatment. Evaluation of vaccine protection against new infections and resultant lesions warrants further consideration in future studies. PMID:26892991

Cervical cancer (CC) is the leading cause of cancer-related death among women in sub-Saharan Africa, primarily because of limited access to effective screening and preventive treatment. Our aim was to assess the feasibility of a human papillomavirus (HPV)-based CC screen-and-treat approach in a low-resource context. We recruited 1012 women aged 30-49 years through a CC screening campaign conducted in the District Hospital of Dschang, Cameroon. Participants performed HPV self-sampling, which was tested for high-risk HPV (HR-HPV) DNA using the point-of-care Xpert HPV assay. All HPV-positive women were invited for visual inspection with acetic acid and Lugol's iodine (VIA/VILI) to exclude CC or enable triage. A cervical sample for histological analysis was also collected. Women positive for HPV 16/18/45 and for other HR-HPV with pathological VIA/VILI were selected to undergo treatment with thermocoagulation. The HPV prevalence in the study population was 18.5% (n = 187); of these cases, 20 (10.6%), 42 (22.3%) and 140 (74.9%) were positive for HPV16, HPV18/45 and other HR-HPV types, respectively. Overall, 107/185 (57.8%) VIA/VILI examinations were classified as pathological and 78 (42.2%) as normal. Women positive for HPV16/18/45 were 4.2 times more likely to harbor cervical intraepithelial neoplasia grade 2 or worse (CIN2+) than those with other HPV types. The specificity of HPV 16/18/45 genotypes for detection of high-grade lesions among HR-HPV positive women was higher than that of VIA/VILI in all age groups. The sensitivity and specificity of VIA/VILI in detecting CIN2+ among HPV positive women were 80% and 44%, respectively. Overall, 110/121 screen-positive women (90.9%) were eligible for, and were treated with, thermocoagulation. An HPV-based screen-and-treat approach is feasible in a low-resource context and may contribute to improving the effectiveness of CC prevention programs. Immediate thermocoagulation treatment for women who are HPV16- and/or HPV18/45-positive is a practical approach for the treatment of CIN2+. The combination of HPV-testing and VIA/VILI for CC screening might reduce overtreatment. © 2017 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

Purpose: To evaluate the long-term results of computed tomography (CT)–planned high-dose-rate (HDR) brachytherapy (BT) for treating cervical cancer patients. Methods and Materials: CT-planned HDR BT was performed according to the adapted Group European de Curietherapie-European Society for Therapeutic Radiology and Oncology (GEC-ESTRO) recommendations in 216 consecutive patients with locally advanced cervical cancer, International Federation of Gynecology and Obstetrics (FIGO) stage IB to IVA, who were treated with conformal external beam radiation therapy and concomitant chemotherapy. We analyzed outcomes and late side effects evaluated according to the Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer and Subjective, Objective,more » Management, Analysis evaluation scoring system and compared them with the results from a historical group. Results: The median age was 56 years (range, 32-83 years). The median follow-up time for living patients was 52 months (range 37-63 months). The 5-year cumulative incidence function for the local recurrence rate for patients with FIGO II and III was 5.5% and 20%, respectively (P=.001). The 5-year rates of overall survival (OS) and disease-free survival (DFS) were 66.4% and 58.5%, respectively. The relative risk of failure for OS and DFS for FIGO III in relation to FIGO II was 2.24 (P=.003) and 2.6 (P=.000) and for lymph node enlargement was 2.3 (P=.002) and 2 (P=.006), respectively. In 2 patients, rectovaginal fistula occurred, and in 1 patient, vesicovaginal fistula occurred without local progression. Comparison of late adverse effects in patients treated according to the GEC-ESTRO recommendations and in the historical group revealed a reduction in fistula formation of 59% and also a reduction in rectal grade 3 to 4 late toxicity of >59%. Conclusions: This is the largest report with mature data of CT-planned BT HDR for the treatment of cervical cancer with good local control and acceptable toxicity. In comparison with the historical series, there is a substantial benefit in terms of severe late effects. FIGO III and enlarged lymph nodes in positron emission tomography–CT/CT are negative prognostic factors, both with a relative risk of failure of approximately 2.« less

MicroRNAs (miRNAs) are short non-coding RNAs that regulate genes posttranscriptionally. Past studies have reported that miR-210 is up-regulated in many cancers including cervical cancer, and plays a pleiotropic role in carcinogenesis. However, its role in regulating response towards anti-cancer agents has not been fully elucidated. We have previously reported that the natural compound 1’S-1’-acetoxychavicol acetate (ACA) is able to induce cytotoxicity in various cancer cells including cervical cancer cells. Hence, this study aims to investigate the mechanistic role of miR-210 in regulating response towards ACA in cervical cancer cells. In the present study, we found that ACA down-regulated miR-210 expression in cervical cancer cells, and suppression of miR-210 expression enhanced sensitivity towards ACA by inhibiting cell proliferation and promoting apoptosis. Western blot analysis showed increased expression of mothers against decapentaplegic homolog 4 (SMAD4), which was predicted as a target of miR-210 by target prediction programs, following treatment with ACA. Luciferase reporter assay confirmed that miR-210 binds to sequences in 3′UTR of SMAD4. Furthermore, decreased in SMAD4 protein expression was observed when miR-210 was overexpressed. Conversely, SMAD4 protein expression increased when miR-210 expression was suppressed. Lastly, we demonstrated that overexpression of SMAD4 augmented the anti-proliferative and apoptosis-inducing effects of ACA. Taken together, our results demonstrated that down-regulation of miR-210 conferred sensitivity towards ACA in cervical cancer cells by targeting SMAD4. These findings suggest that combination of miRNAs and natural compounds could provide new strategies in treating cervical cancer. PMID:28401751

Cervical cancer is a leading cause of cancer death for women all across the developing world, where much of the infrastructure required for effective cervical cancer screening is unavailable because of limited resources. One of the most common method to screen for cervical cancer is by visual inspection with acetic acid (VIA), in which the cervix is imaged with the naked eye. Given inherent challenges in analysis and documentation when characterizing cervical tissue with the naked eye, an optical solution is needed. To address this challenge, a smartphone was modified and transformed into a mobile colposcope (a device used to image the cervix from outside) by adding a custom-fit light source and optics. The mobile smartphone colposcope was designed such that it augments VIA and easily integrates within the standard of care. The mobile smartphone colposcope is controlled by an app, which, stores cervical images captured on the mobile smartphone colposcope on a portal, enabling remote doctors to evaluate images and the treatment chosen by the health worker. Images from patients undergoing cervical cancer screening by a nurse using VIA in the University Hospital of Mirebalais (HUM) GYN outpatient clinic in Haiti were captured on the mobile smartphone colposcope. These images were later analyzed by an experienced OB/GYN at HUM, who determined whether or not the patient should be treated with cryoablation; more complicated cases were also shared with a consulting doctor in the US. The opinions of the experienced OB/GYN doctors at HUM, as well as the experts from the US, were used to educate nurses and midwives performing mobile colposcopy. These results suggest that remote assessment offered by mobile colposcopy can improve training of health workers performing VIA, and ultimately affect the therapy administered to patients.

Telomeres are transcribed into long non-coding RNA, referred to as telomeric repeat-containing RNA (TERRA), which plays important roles in maintaining telomere integrity and heterochromatin formation. TERRA has been well characterized in HeLa cells, a type of cervical cancer cell. However, TERRA abundance and stability have not been examined in other cervical cancer cells, at least to the best of our knowledge. Thus, in this study, we measured TERRA levels and stability, as well as telomere length in 6 cervical cancer cell lines, HeLa, SiHa, CaSki, HeLa S3, C-33A and SNU-17. We also examined the association between the TERRA level and its stability and telomere length. We found that the TERRA level was several fold greater in the SiHa, CaSki, HeLa S3, C-33A and SNU-17 cells, than in the HeLa cells. An RNA stability assay of actinomycin D-treated cells revealed that TERRA had a short half-life of ~4 h in HeLa cells, which was consistent with previous studies, but was more stable with a longer half-life (>8 h) in the other 5 cell lines. Telomere length varied from 4 to 9 kb in the cells and did not correlate significantly with the TERRA level. On the whole, our data indicate that TERRA abundance and stability vary between different types of cervical cancer cells. TERRA degrades rapidly in HeLa cells, but is maintained stably in other cervical cancer cells that accumulate higher levels of TERRA. TERRA abundance is associated with the stability of RNA in cervical cancer cells, but is unlikely associated with telomere length.

This is a retrospective study of patients with cervical myelopathy resulting from adjacent-segment disease who were treated by open-door expansive laminoplasty. The purpose of this study was to evaluate the effectiveness of laminoplasty for cervical myelopathy resulting from adjacent-segment disease. Adjacent-segment disease is one of the problems associated with anterior cervical decompression and fusion. However, the optimal surgical management strategy is still controversial. Thirty-one patients who underwent open-door expansive laminoplasty for cervical myelopathy resulting from adjacent-segment disease and age- and sex-matched 31 patients with myelopathy who underwent laminoplasty as the initial surgery were enrolled in the study. The pre- and postoperative Japanese Orthopedic Association scores (JOA scores) and the recovery rate were compared between the two groups. The average JOA scores in the patients with adjacent-segment disease and the controls were 9.2 +/- 2.6 and 9.4 +/- 2.3 before the expansive laminoplasty and 11.9 +/- 2.8 and 13.3 +/- 1.7 at the follow-up examination, respectively; the average recovery rates in the two groups were 37.1 +/- 22.4% and 50.0 +/- 21.3%, respectively (P = 0.04). The mean number of segments covered by the high-intensity lesions on the T2-weighted magnetic resonance images was 1.87 and 0.9, respectively (P = 0.001). Moderate neurologic recovery was obtained after open-door laminoplasty in patients with cervical myelopathy resulting from adjacent-segment disc disease, although the results were not as satisfactory as those in the control group. This may be attributed to the irreversible damage of the spinal cord caused by persistent compression at the adjacent segments.

Intractable cervical radiculopathy secondary to stenosis or herniated nucleus pulposus is commonly treated with an anterior cervical decompression and fusion (ACDF) procedure. However, there is little evidence in the literature that demonstrates the impact such surgery has on long-term range of motion (ROM) outcomes. The objective of this study was to compare cervical ROM and patient-reported outcomes in patients before and after a 1, 2, or 3 level ACDF. Prospective, nonexperimental. Forty-six patients. The following were measured preoperatively and also at 3 and 6 months after ACDF: active ROM (full and painfree) in three planes (ie, sagittal, coronal, and horizontal), pain visual analog scale, Neck Disability Index, and headache frequency. Patients undergoing an ACDF for cervical radiculopathy had their cervical ROM measured preoperatively and also at 3 and 6 months after the procedure. Neck Disability Index and pain visual analog scale values were also recorded at the same time. Both painfree and full active ROM did not change significantly from the preoperative measurement to the 3-month postoperative measurement (ps>.05); however, painfree and full active ROM did increase significantly in all three planes of motion from the preoperative measurement to the 6-month postoperative measurement regardless of the number of levels fused (ps≤.023). Visual analog scale, Neck Disability Index, and headache frequency all improved significantly over time (ps≤.017). Our results suggest that patients who have had an ACDF for cervical radiculopathy will experience improved ROM 6 months postoperatively. In addition, patients can expect a decrease in pain, an improvement in neck function, and a decrease in headache frequency. Copyright © 2013 Elsevier Inc. All rights reserved.

OBJECTIVE Cervical total disc replacement (TDR) has been shown in a number of prospective clinical studies to be a viable treatment alternative to anterior cervical discectomy and fusion (ACDF) for the treatment of symptomatic degenerative disc disease. In addition to preserving motion, evidence suggests that cervical TDR may result in a lower incidence of subsequent surgical intervention than treatment with fusion. The goal of this study was to evaluate subsequent surgery rates up to 5 years in patients treated with TDR or ACDF at 1 or 2 contiguous levels between C-3 and C-7. METHODS This was a prospective, multicenter, randomized, unblinded clinical trial. Patients with symptomatic degenerative disc disease were enrolled to receive 1- or 2-level treatment with either TDR as the investigational device or ACDF as the control treatment. There were 260 patients in the 1-level study (179 TDR and 81 ACDF patients) and 339 patients in the 2-level study (234 TDR and 105 ACDF patients). RESULTS At 5 years, the occurrence of subsequent surgical intervention was significantly higher among ACDF patients for 1-level (TDR, 4.5% [8/179]; ACDF, 17.3% [14/81]; p = 0.0012) and 2-level (TDR, 7.3% [17/234]; ACDF, 21.0% [22/105], p = 0.0007) treatment. The TDR group demonstrated significantly fewer index- and adjacent-level subsequent surgeries in both the 1- and 2-level cohorts. CONCLUSIONS Five-year results showed treatment with cervical TDR to result in a significantly lower rate of subsequent surgical intervention than treatment with ACDF for both 1 and 2 levels of treatment.

Cervical cancer is the second commonest type and third cause of cancer death among women in low-income countries. Women living with HIV/AIDS are at greater risk of developing cervical cancer. The study aimed to identify the determinant factors forsuspected precancerous cervical lesions among HIV- positive women in Mekelle hospital, Ethiopia. Anunmatched case-control study was conducted among randomly selected HIV positive women in Mekelle hospital in 2014. In Mekelle Hospital, routine screening for lesions of the cervix uteri by visual inspection with acetic acid (VIA) is done in HIV positive women by trained nurses. Suspicious findings are treated by cryotherapy or referred to the Gynaecologist. A number of 116 cases, who had suspicious findings on VIA, and 232 HIV-positive controls without suspicious findings on VIA were randomly selected and enrolled into the study The determinant factors for precancerous cervical lesion were analyzed using multiple logistic regression and described as adjusted odds ratio (AOR). HIV positive women who had CD4 cells less than 350/mm3 were two times more likely to have precancerous cervical lesion compared to those with CD4 cells above 350/mm3. Women with two (AOR = 3.6; 95% CI: 1.7, 7.7) and three (AOR = 2.5; 95% CI: 1.2, 5.4) sexual partners were four and three times more likely to have precancerous cervical lesion, respectively, as compared to those who had one sexual partner. Age, History of STI and duration of ART had no influence on presence of VIA positive lesions in HIV positive women. CD4 count cells and number of sexual partners were predictors of VIA positive cervical lesion among HIV positive women.

The American Society for Colposcopy and Cervical Pathology Colposcopy Standards address the role of and approach to colposcopy and biopsy for cervical cancer prevention in the United States. Working Group 1 was tasked with defining the role of colposcopy, describing benefits and potential harms, and developing an official terminology. A systematic literature review was performed. A national survey of American Society for Colposcopy and Cervical Pathology members provided input on current terminology use. The 2011 International Federation for Cervical Pathology and Colposcopy terminology was used as a template and modified to fit colposcopic practice in the United States. For areas without data, expert consensus guided the recommendation. Draft recommendations were posted online for public comment and presented at an open session of the 2017 International Federation for Cervical Pathology and Colposcopy World Congress for further comment. All comments were considered for the final version. Colposcopy is used in the evaluation of abnormal or inconclusive cervical cancer screening tests. Colposcopy aids the identification of cervical precancers that can be treated, and it allows for conservative management of abnormalities unlikely to progress. The potential harms of colposcopy include pain, psychological distress, and adverse effects of the procedure. A comprehensive colposcopy examination should include documentation of cervix visibility, squamocolumnar junction visibility, presence of acetowhitening, presence of a lesion(s), lesion(s) visibility, size and location of lesions, vascular changes, other features of lesion(s), and colposcopic impression. Minimum criteria for reporting include squamocolumnar junction visibility, presence of acetowhitening, presence of a lesion(s), and colposcopic impression. A recommended terminology for use in US colposcopic practice was developed, with comprehensive and minimal criteria for reporting.

The current Australian National Cervical Screening Program (NCSP) involves biennial, cytology-based screening of women from the age of 18 years. From December, 2017 this will change to a five-yearly human papilloma virus-based screening commencing at age 25. There is some concern that the new program may delay the opportunistic detection of cervical cancers in women under 25 years. (1) To review all cases of invasive cervical cancer in Queensland women under the age of 25 over the last 28 years. (2) To determine symptoms and screening history prior to diagnosis. A retrospective cohort study was undertaken at the Queensland Centre for Gynaecological Cancer (QCGC) and the Queensland Cancer Registry (QCR) of all women aged between 13 and 25 years diagnosed with cervical cancer in Queensland between 1984 and 2012. Demographic data and symptoms prior to diagnosis were extracted from the QCGC and QCR databases. A total of 56 women aged 13-25, were diagnosed with cervical cancer and treated at the QCGC between 1984 and 2012. The commonest reason for the diagnosis of cancer was investigation of abnormal symptoms (n = 22, 39%) rather than routine Pap smear abnormalities (n = 15, 26%). Consistent with the world literature, there is a very low incidence of cervical cancer in women under 25 years of age, irrespective of the age of commencement of screening, or the screening interval. Our study lends some support to the proposed commencement age of 25 years in the new NCSP. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Why does cervical cancer occur in a state-of-the-art screening program?

The goal of cervical screening is to detect and treat precancers before some become cancer. We wanted to understand why, despite state-of-the-art methods, cervical cancers occured in relationship to programmatic performance at Kaiser Permanente Northern California (KPNC), where >1,000,000 women aged ≥30years have undergone cervical cancer screening by triennial HPV and cytology cotesting since 2003. We reviewed clinical histories preceding cervical cancer diagnoses to assign "causes" of cancer. We calculated surrogate measures of programmatic effectiveness (precancers/(precancers and cancers)) and diagnostic yield (precancers and cancers per 1000 cotests), overall and by age at cotest (30-39, 40-49, and ≥50years). Cancer was rare and found mainly in a localized (treatable) stage. Of 623 cervical cancers with at least one preceding or concurrent cotest, 360 (57.8%) were judged to be prevalent (diagnosed at a localized stage within one year or regional/distant stage within two years of the first cotest). Non-compliance with recommended screening and management preceded 9.0% of all cancers. False-negative cotests/sampling errors (HPV and cytology negative), false-negative histologic diagnoses, and treatment failures preceded 11.2%, 9.0%, and 4.3%, respectively, of all cancers. There was significant heterogeneity in the causes of cancer by histologic category (p<0.001 for all; p=0.002 excluding prevalent cases). Programmatic effectiveness (95.3%) and diagnostic yield were greater for squamous cell versus adenocarcinoma histology (p<0.0001) and both decreased with older ages (p trend <0.0001). A state-of-the-art intensive screening program results in very few cervical cancers, most of which are detected early by screening. Screening may become less efficient at older ages.

To compare patterns of failure, late toxicities, and survival in locally advanced cervical cancer patients treated by either low-dose-rate (LDR) or conformal high-dose-rate (HDRc) brachytherapy as a part of curative radiotherapy. A retrospective comparative study of 217 advanced cervix cancer patients was conducted; 90 of these patients received LDR and 127 received HDRc brachytherapy. All patients were staged using International Federation of Gynecology and Obstetrics (FIGO) rules, had pretreatment magnetic resonance imaging (MRI), and were treated with concurrent cisplatin chemoradiotherapy. Both groups matched for FIGO stage, MRI tumor volume, and uterine invasion status. Local and pelvic failures were similar 12-13% and 14% both in both groups. Abdominal and systemic failures in LDR group were 21% and 24%, whereas corresponding failures in HDRc group were 20% and 24%. Sixty-eight percent (87/127) of patients treated by HDRc remained asymptomatic, whereas 42% (38/90) of patients were asymptomatic from the bowel and bladder symptoms after treatment with LDR. The 5-year OS rate was 60% (SE = 4%). The 5-year failure-free survival rate was 55% (SE = 3%). There was no significant difference between the groups. Image-guided HDRc planning led to a large decrease in late radiation effects in patients treated by HDRc. Patterns of failure and survival were similar in patients treated either by LDR or HDRc.

Background Cervical total disc replacement (TDR) is an increasingly accepted procedure for the treatment of symptomatic cervical degenerative disc disease. Multiple Level I evidence clinical trials have established cervical TDR to be a safe and effective procedure in the short-term. The objective of this study is to provide a long-term assessment of TDR versus anterior discectomy and fusion for the treatment of one- and two-level disc disease. Methods This study was a continuation of a prospective, multicenter, randomized, US FDA IDE clinical trial comparing cervical TDR with the Mobi-C© Cervical Disc versus ACDF through 7 years follow-up. Inclusion criteria included a diagnosis of symptomatic cervical degenerative disc disease at one or two cervical levels. TDR patients were treated using a Mobi-C© artificial disc (Zimmer Biomet, Austin TX, USA). ACDF with allograft and anterior plate was used as a control treatment. Outcome measures were collected preoperatively and postoperatively at 6 weeks, at 3, 6, 12, 18 months, annually through 60 months, and at 84 months. Measured outcomes included Overall success, Neck Disability Index (NDI), VAS neck and arm pain, segmental range of motion (ROM), patient satisfaction, SF-12 MCS/PCS, major complications, and subsequent surgery rate. The primary endpoint was an FDA composite definition of success comprising clinical improvement and an absence of major complications and secondary surgery events. Results A total of 599 patients were enrolled and treated, with 164 treated with one-level TDR, 225 treated with two-level TDR, 81 treated with one-level ACDF, and 105 treated with two-level ACDF. At seven years, follow-up rates ranged from 73.5% to 84.4% (overall 80.2%). The overall success rates of two level TDR and ACDF patients were 60.8% and 34.2%, respectively (p<0.0001). The overall success rates of one level TDR and ACDF patients were 55.2% and 50%, respectively (p>0.05). Both the single and two level TDR and ACDF groups showed significant improvement from baseline NDI scores, VAS neck and arm pain scores, and SF-12 MCS/PCS scores (p<0.0001). In the single level cohort, there was an increased percentage of TDR patients who reported themselves as “very satisfied” (TDR 90.9% vs ACDF 77.8%; p= 0.028). There was a lower rate of adjacent level secondary surgery in the single level TDR patients (3.7%) versus the ACDF patients (13.6%; p = 0.007). In the two level TDR group, the NDI success rate was significantly greater in the TDR group (TDR: 79.0% vs. ACDF: 58.0%; p=0.001). There was significantly more improvement in NDI change score at 7 years in the TDR patients versus ACDF. The TDR group had a significantly higher rate of patients who were “very satisfied” with their treatment compared to the ACDF group (TDR: 85.9% vs. ACDF: 73.9%). The rate of subsequent surgery at the index level was significantly lower in the TDR group compared to the ACDF group (TDR: 4.4% vs. ACDF: 16.2%; p=0.001). The rate of adjacent level secondary surgery was significantly lower in the two level TDR (4.4%) patients compared to the ACDF (11.3%; p=0.03) patients. In both single and two level cohorts, the percentage of patients with worse NDI (2.5%-3.8% of two level surgeries and 1.2%-2.5% of single level surgeries) or worse neck pain (5%-6.8% of the two level surgeries and 1.3% - 3.8% of the single level surgeries) was strikingly low in both groups but trended lower in the TDR patients. Conclusions At seven years, the composite success analysis demonstrated clinical superiority of two level TDR over ACDF and non-inferiority of single level TDR versus ACDF. There were lower rates of secondary surgery and higher adjacent level disc survivorship in both groups. Both surgeries were remarkably effective in alleviating pain relative to baseline and the rate of patients with worse disability or neck pain was surprisingly low. Overall, greater than 95% of patients (from both groups) who underwent TDR and 88% of patients who underwent ACDF were “very satisfied” at seven years. The differences in clinical effectiveness of TDR versus ACDF becomes more apparent as treatment increases from one to two levels, indicating a significant benefit for TDR over ACDF for two-level procedures. Ethical Standards The Mobi-C Clinical Trial (ClinicalTrials.gov registration number: NCT00389597) was conducted at 24 sites in the US and was approved by the Institutional Review Board, Research Ethics Committee, or local equivalent of each participating site.

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

Cervical cystic lymphangioma (CCL) is a rare and benign tumour involving congenital and cystic abnormalities derived from lymphatic vessels. The most accepted treatment continues to be surgical excision. However, when this infiltrates vital neurovascular neck structures, complete excision is difficult and if only partial, the recurrence rate is very high. The most frequently used alternative treatment is to inject sclerosants into the lesion. The use of these techniques has reported good results in children; however, there are few references thereof with regard to adults. We are reporting on a cervical cystic lymphangioma in a male aged 22, treated with an intra-lesion injection of 20 cc with 0.01 mg/cc dilution of OK-432 (picibanil) in physiological serum. Sole complications were fever and local reaction where the solution was injected. One month after treatment the lymphangioma had totally remitted and sixteen months later continues in remittance.

We report the case of a patient with carcinoma "en cuirasse" of the vulva. A female patient presented complaining of inguinal lymphadenopathy. Lymph node excision, immunohistochemistry analyses, and further exams showed the presence of cervical adenocarcinoma. The cancer was surgically removed and the patient was treated with radiotherapy and chemotherapy with a good initial response. Some months later she presented with intense edema of the lower limbs, hardening and thickening of the labia majora, and pelvic and genital ulceration. A cutaneous biopsy with subsequent immunohistochemical staining showed lymphatic dissemination of adenocarcinoma to the vulva. Carcinoma "en cuirasse" is a rare presentation of cutaneous metastasis in which the affected skin shows hardening and induration, acquiring a sclerodermoid appearance. This is, to the best of our knowledge, the first report in Brazil of carcinoma "en cuirasse" of the vulva associated with cervical adenocarcinoma.

Coronary artery disease predisposes to atrial fibrillation (AF), but the effects of chronic atrial ischemia/infarction on AF-related substrates are unknown. Regional right atrial myocardial infarction (MI) was created in 40 dogs by ligating an artery that supplies the right atrial free wall and not the ventricles; 35 sham dogs with the same artery isolated but not ligated were controls. Dogs were observed 8 days after MI and subjected to open-chest study, in vitro optical mapping, and/or cell isolation for patch-clamp and Ca(2+) imaging on day 8. Holter ECGs showed more spontaneous atrial ectopy in MI dogs (eg, 662±281 on day 7 versus 34±25 ectopic complexes per day at baseline; 52±21 versus 1±1 atrial tachycardia episodes per day). Triggered activity was increased in MI border zone cells, which had faster decay of caffeine-evoked Ca(2+) transients and enhanced (by ≈73%) Na(+)-Ca(2+) exchange current. Spontaneous Ca(2+) sparks (confocal microscopy) occurred under β-adrenergic stimulation in more MI dog cells (66±9%) than in control cells (29±4%; P<0.01). Burst pacing induced long-lasting AF in MI dogs (1146±259 versus 30±14 seconds in shams). Increased border zone conduction heterogeneity was confirmed by both bipolar electrode mapping in vivo and optical mapping. Optical mapping demonstrated stable border zone reentry in all 9 MI preparations but in none of 6 shams. Border zone tissue showed increased fibrous tissue content. Chronic atrial ischemia/infarction creates substrates for both spontaneous ectopy (Ca(2+)-release events, increased Na(+)-Ca(2+) exchange current) and sustained reentry (conduction abnormalities that anchor reentry). Thus, chronic atrial infarction in dogs promotes both AF triggers and the substrate for AF maintenance. These results provide novel insights into potential AF mechanisms in patients with coronary artery disease.

Torres, Mylin A.; Jhingran, Anuja; Thames, Howard D.

Purpose: To compare the treatment and outcomes of cervical cancer patients treated with concurrent chemoradiotherapy (CT-RT) in a multi-institutional trial or as standard care. Patients and Methods: We reviewed the records of 302 patients treated with CT-RT for locoregionally confined, intact cervical cancer between 1990 and 2005. Of the 302 patients, 76 were treated using cisplatin and 5-fluorouracil (C/F) on Radiation Therapy Oncology Group protocol 90-01 (CT-RT{sub 90-01}); 226 underwent CT-RT as standard care with either C/F [CT-RT{sub SC(C/F)}; n = 115] or weekly cisplatin [CT-RT{sub SC(WC)}; n = 111). Results: The CT-RT{sub 90-01} patients more often had tumors {>=}6more » cm and were less often diabetic than were the CT-RT{sub SC} patients. The CT-RT{sub SC(WC)} patients were more likely than the CT-RT{sub SC(C/F)} patients to be {>=}60 years old or to have Stage III-IV disease. During treatment, CT-RT{sub SC(C/F)} patients experienced more Grade 2-3 neutropenia and were, therefore, less likely to receive 200 mg/m{sup 2} cisplatin than were either CT-RT{sub SC(WC)} or CT-RT{sub 90-01} patients (52% vs. 77% vs. 85%, respectively; p <0.001). At 5 years, the disease-specific survival rates were greater for patients treated with C/F [CT-RT{sub SC(C/F)}, 75%; CT-RT{sub 90-01}, 79%] than for those treated with CT-RT{sub SC(WC)} (58%; p = 0.02). On multivariate analysis, C/F chemotherapy, cisplatin dose {>=}200 mg/m{sup 2}, Stage I-II disease, and negative pelvic lymph nodes were independent predictors of improved disease-specific survival. Conclusions: Even within a large comprehensive cancer center, the high rates of chemotherapy completion achieved on a multi-institutional trial can be difficult to reproduce in standard practice. Although C/F toxicity was greater in the standard care patients, their outcomes were similar to those of patients treated with C/F on Radiation Therapy Oncology Group protocol 90-01.« less

Longitudinal Changes in Active Bone Marrow for Cervical Cancer Patients Treated With Concurrent Chemoradiation Therapy

DOE Office of Scientific and Technical Information (OSTI.GOV)

Noticewala, Sonal S.; Li, Nan; Williamson, Casey W.

Purpose: To quantify longitudinal changes in active bone marrow (ABM) distributions within unirradiated (extrapelvic) and irradiated (pelvic) bone marrow (BM) in cervical cancer patients treated with concurrent chemoradiation therapy (CRT). Methods and Materials: We sampled 39 cervical cancer patients treated with CRT, of whom 25 were treated with concurrent cisplatin (40 mg/m{sup 2}) and 14 were treated with cisplatin (40 mg/m{sup 2}) plus gemcitabine (50-125 mg/m{sup 2}) (C/G). Patients underwent {sup 18}F-fluorodeoxyglucose positron emission tomographic/computed tomographic imaging at baseline and 1.5 to 6.0 months after treatment. ABM was defined as the subvolume of bone with standardized uptake value (SUV) above the mean SUV ofmore » the total bone. The primary aim was to measure the compensatory response, defined as the change in the log of the ratio of extrapelvic versus pelvic ABM percentage from baseline to after treatment. We also quantified the change in the proportion of ABM and mean SUV in pelvic and extrapelvic BM using a 2-sided paired t test. Results: We observed a significant increase in the overall extrapelvic compensatory response after CRT (0.381; 95% confidence interval [CI]: 0.312, 0.449) and separately in patients treated with cisplatin (0.429; 95% CI: 0.340, 0.517) and C/G (0.294; 95% CI: 0.186, 0.402). We observed a trend toward higher compensatory response in patients treated with cisplatin compared with C/G (P=.057). Pelvic ABM percentage was reduced after CRT both in patients receiving cisplatin (P<.001) and in those receiving C/G (P<.001), whereas extrapelvic ABM percentage was increased in patients receiving cisplatin (P<.001) and C/G (P<.001). The mean SUV in pelvic structures was lower after CRT with both cisplatin (P<.001) and C/G (P<.001). The mean SUV appeared lower in extrapelvic structures after CRT in patients treated with C/G (P=.076) but not with cisplatin (P=.942). We also observed that older age and more intense chemotherapy regimens were correlated with a decreased compensatory response on multivariable analysis. In patients treated with C/G, mean pelvic bone marrow dose was found to be negatively correlated with the compensatory response. Conclusion: Patients have differing subacute compensatory responses after CRT, owing to variable recovery in unirradiated marrow. Intensive chemotherapy regimens appear to decrease the extrapelvic compensatory response, which may lead to increased hematologic toxicity.« less

Cervical cancer is a predominantly human papillomavirus (HPV)-driven disease worldwide. However, its incidence is unexplainably low in western Asia, including Saudi Arabia. Using this paradigm, we investigated the role of HPV infection rate and host genetic predisposition in TP53 G72C single nucleotide polymorphism (SNP) presumed to affect cancer incidence. Patients treated between 1990 and 2012 were reviewed, and a series of 232 invasive cervical cancer cases were studied and compared with 313 matched controls without cancer. SNP was genotyped by way of direct sequencing. HPV linear array analysis was used to detect and genotype HPV in tumor samples. The incidence of cervical cancer revealed bimodal peaks at 42.5 years, with a slighter rebound at 60.8 years. Among all cases, 77% were HPV-positive and 16 HPV genotypes were detected-mostly genotypes 16 (75%) and 18 (9%)-with no difference by age, histology, or geographical region. Although the TP53 G72C genotype was not associated with overall cervical cancer risk, it was significantly associated with HPV positivity (odds ratio, 0.57; 95% confidence interval, 0.36-0.90; P = .016). Furthermore, the variant C allele was significantly overtransmitted in the population (P < .0003). Cervical cancer incidence displays bimodal curve peaking at a young age with secondary rebound at older age. The combination of relative low HPV infection and variant TP53 72C allele overtransmission provide a plausible explanation for the low incidence of cervical cancer in our population. Therefore, HPV screening and host SNP genotyping may provide more relevant biomarkers to gauge the risk of developing cervical cancer.

OBJECTIVE Bony overgrowth and spontaneous fusion are complications of cervical arthroplasty. In contrast, bone loss or bone remodeling of vertebral bodies at the operation segment after cervical arthroplasty has also been observed. The purpose of this study is to investigate a potential complication-bone loss of the anterior portion of the vertebral bodies at the surgically treated segment after cervical total disc replacement (TDR)-and discuss the clinical significance. METHODS All enrolled patients underwent follow-up for more than 24 months after cervical arthroplasty using the Baguera C disc. Clinical evaluations included recording demographic data and measuring the visual analog scale and Neck Disability Index scores. Radiographic evaluations included measurements of the functional spinal unit's range of motion and changes such as bone loss and bone remodeling. The grading of the bone loss of the operative segment was classified as follows: Grade 1, disappearance of the anterior osteophyte or small minor bone loss; Grade 2, bone loss of the anterior portion of the vertebral bodies at the operation segment without exposure of the artificial disc; or Grade 3, significant bone loss with exposure of the anterior portion of the artificial disc. RESULTS Forty-eight patients were enrolled in this study. Among them, bone loss developed in 29 patients (Grade 1 in 15 patients, Grade 2 in 6 patients, and Grade 3 in 8 patients). Grade 3 bone loss was significantly associated with postoperative neck pain (p < 0.05). Bone loss was related to the motion preservation effect of the operative segment after cervical arthroplasty in contrast to heterotopic ossification. CONCLUSIONS Bone loss may be a potential complication of cervical TDR and affect early postoperative neck pain. However, it did not affect mid- to long-term clinical outcomes or prosthetic failure at the last follow-up. Also, this phenomenon may result in the motion preservation effect in the operative segment after cervical TDR.

Background Cervical cancer is the most common reproductive health cancer in Malawi. In most cases, women report to health facilities when the disease is in its advanced stage. In this study, we investigate service providers’ perceptions about barriers for women to access cervical cancer screening and early treatment services in Malawi. Methods We conducted in-depth interviews with 13 district coordinators and 40 service providers of cervical cancer screening and early treatment services in 13 districts in Malawi. The study was conducted in 2012. The district coordinators helped the research team identify the health facilities which were providing cervical cancer screening and early treatment services. Results Almost all informants reported that cervical cancer was a major public health problem in their districts and that prevention efforts for this disease were being implemented. They were aware of the test and treat approach using visual inspection with acetic acid (VIA). They, however, said that the delivery of cervical cancer screening and early treatment services was compromised because of factors such as gross shortage of staff, lack of equipment and supplies, the lack of supportive supervision, and the use of male service providers. Informants added that the lack of awareness about the disease among community members, long distances to health facilities, the lack of involvement of husbands, and prevailing misperceptions about the disease (eg, that it is caused by the exposure to the VIA process) affect the uptake of these services. Conclusion While progress has been made in the provision of cervical cancer screening and early treatment services in Malawi, a number of factors affect service delivery and uptake. There is a need to continue creating awareness among community members including husbands and also addressing identified barriers such as shortage of staff and supplies in order to improve uptake of services.

A carbothioamide NSO tridentate Schiff base ligand (HL) and its square planar complexes Na[NiLOAc], Na[PdLOAc] and [PtLdmso] have been synthesized and characterized on the basis of melting point, elemental analysis, FT-IR, 1H NMR, 13C NMR, UV-Vis spectra. The structure of HL was elucidated with X-ray diffraction analysis. In the present study, the synthesized compounds were evaluated for their anticancer properties against three human cancer cell lines breast cancer (MCF-7), cervical (Hela), and colon (HCT-116). In addition, the cytotoxicity of the synthesized compounds was tested on a normal human cell line (human endothelial cell line EA.hy926). Among the tested compounds, the complex [NiLOAc] excelled in halting proliferation of the cervical and colon cancer cells with median inhibitory concentration (IC50) values of 28.33 and 34.4 μM, respectively. The complex, [PdLOAc] demonstrated selective cytotoxicity against breast cancer line MCF-7 with IC50 = 47.5 μM, while HL showed inhibitory effect against colon cancer cell line (HCT-116) with IC50 = 55.66 μM. The complex, [PtLdmso] showed mild activity against breast cancer (MCF-7) and cervical cancer (Hela) cells with IC50 = 64.44 and 68.3 μM, respectively, whereas, it displayed insignificant cytotoxicity against human endothelial cells (EA.hy926) with IC50 > 200 μM. Cancer cells treated with [NiLOAc] showed apoptotic features such as membrane blebbing and DNA condensation. Thus, the findings of the present study demonstrated that the series of metal complexes of HL could form the new lead for development of cancer chemotherapies to treat human cervical, breast and colon malignancies.

Owing to the technical and logistical complexities of matching photon and proton treatment modalities, we developed and implemented a technique of comprehensive head and neck radiation using 3-dimensional (3D) conformal proton therapy. A monoisocentric technique was used with a 30-cm snout. Cervical lymphatics were treated with 3 fields: a posterior-anterior field with a midline block and a right and a left posterior oblique field. The matchline of the 3 cervical nodal fields with the primary tumor site fields was staggered by 0.5 cm. Comparative intensity-modulated photon plans were later developed for 12 previously treated patients to provide equivalent target coverage,more » while matching or improving on the proton plans' sparing of organs at risk (OARs). Dosimetry to OARs was evaluated and compared by treatment modality. Comprehensive head and neck irradiation using proton therapy yielded treatment plans with significant dose avoidance of the oral cavity and midline neck structures. When compared with the generated intensity-modulated radiation therapy (IMRT) plans, the proton treatment plans yielded statistically significant reductions in the mean and integral radiation dose to the oral cavity, larynx, esophagus, and the maximally spared parotid gland. There was no significant difference in mean dose to the lesser-spared parotid gland by treatment modality or in mean or integral dose to the spared submandibular glands. A technique for cervical nodal irradiation using 3D conformal proton therapy with uniform scanning was developed and clinically implemented. Use of proton therapy for cervical nodal irradiation resulted in large volume of dose avoidance to the oral cavity and low dose exposure to midline structures of the larynx and the esophagus, with lower mean and integral dose to assessed OARs when compared with competing IMRT plans.« less

The purpose of this study was to report on the incidence, diagnosis and clinical manifestation of VAI following cervical spine injuries observed in a prospective observational study with a standardized clinical and radiographical protocol. During a 16-year period, 69 (mean age: 43 ± 20.7 years; 25 female, 44 male) of 599 patients had cervical spine injury suspicious for VAI due to facet luxation and/or fractures extending into the transverse foramen. Diagnosis and management of these patients followed a previously published protocol (Kral in Zentralbl Neurochir 63:153-158, 2002). Digital subtraction angiography (DSA) was performed in all 69 patients. Injury grading of VAI was done according to Biffl et al. (Ann Surg 231:672-681, 2000). All patients with VAI were treated with anticoagulation (heparin followed by ASS) for 6 months. In cases suspicious for VAI, the incidence of VAI detected by DSA was 27.5% (n = 19 of 69 patients). VAI Grade I occurred in 15.8%, Grade II in 26.3%, Grade IV in 52.6% and Grade V in 5.2%. Of 19 patients, 4 (21%) had clinical signs of vertebrobasilar ischemia. Two patients died in hospital after 4 and 21 days respectively. Of 69 patients, 33 (47.8%) with suspected VAI had unstable spine injuries and were treated surgically. In patients with cervical spine fractures or dislocations crossing the course of the vertebral artery, VAI are relatively frequent and may be associated with significant morbidity and mortality. VAI were identified by DSA in 27.5%. Despite anticoagulation therapy, 5.8% became clinically symptomatic and 2.9% died due to cerebrovascular ischemia.

Aim To report outcomes for patients with para-aortic lymph node positive cervical cancer treated with a dynamic field-matching technique. Background PET staging of cervical cancer has increased identification of patients with para-aortic lymph node metastasis. IMRT enables dose escalation in this area, but matching IMRT fields with traditional whole pelvis fields presents a challenge. Materials and methods From 2003 to 2012, 20 patients with cervical cancer and para-aortic lymph node metastasis were treated utilizing the dynamic field-matching technique. As opposed to single-isocenter half-beam junction techniques, this technique employs wedge-shaped dose junctions for the abutment of fields. We reviewed the records of all patients who completed treatment with the technique and abstracted treatment, toxicity, and disease-related outcome data for analysis. Results Median prescribed dose to the whole pelvis field was 45 Gy and para-aortic IMRT field 50.4 Gy. All but 3 patients underwent HDR (13 pts) or LDR (4 pts) brachytherapy. All patients developed lower GI toxicity; 10 grade 1, 9 grade 2, and 1 grade 4 (enterovaginal fistula). Median DFS was 12.4 months with 1 and 2-year DFS 60.0% and 38.1%. One-year OS was 83.7% and 2-year OS, 64.4%. A total of 10 patients developed recurrence; none occurred at the matched junction. Conclusions The dynamic field-matching technique provides a means for joining conventional whole pelvis fields and para-aortic IMRT fields that substantially reduces dose deviations at the junction due to field mismatch. Treatment with the dynamic matching technique is simple, effective, and tolerated with no apparent increase in toxicity. PMID:26900356

Retrospective case series OBJECTIVE.: To review clinical and radiological outcomes of craniovertebral surgery in children with Morquio A syndrome (Mucopolysaccharidosis type IVA) and develop an evidence-based management algorithm. Myelopathy secondary to craniovertebral pathology is a common cause of neurological disability in Morquio A syndrome. Previously unresolved surgical controversies include the value of surveillance, surgical indications and operative technique. A retrospective case-based review of children with Morquio A syndrome and craniovertebral pathology seen in a tertiary referral paediatric centre from 1992-2016 was performed. Patients treated non-operatively and operatively were included. Medical records and imaging were reviewed to determine clinical and radiological findings at initial assessment, prior to cervical spine surgery, early post-operative period and final follow-up. The clinical outcomes of interest were neurological status and mobility at follow-up, complications and need for further surgery. Twenty-seven patients were included. Surgical indications were radiological evidence of cervicomedullary compression alone (6 cases) or with clinical evidence of myelopathy (12 cases). Eighteen patients (median age 6.2 years, range 3.5 - 15.9 years) underwent surgery, with median follow-up of 8.5years. Occiput to upper cervical spine fusion with C1 decompression was performed in all cases with the addition of autologous calvarial graft in young patients (12 cases) and occipital-cervical plate fixation in older children (6 cases). Neurological improvement occurred in 38% of cases but by one functional level only. Six of 9 conservatively treated patients remained independent walkers. Surgery for craniovertebral pathology is required in the majority of children with Morquio A syndrome. Close clinical and radiological surveillance is essential for timely intervention. Occiput to cervical fusion is safe and feasible even in young patients and improves clinical and radiological parameters. 4.

The diagnosis of squamous intraepithelial lesions in cervical tissue specimens is subject to substantial variability. Adjunctive immunohistochemical (IHC) staining for p16 has been shown to add objective biomarker information to morphologic interpretation of hematoxylin and eosin (H&E)-stained tissues. In the CERvical Tissue AdjunctIve aNalysis (CERTAIN) study, we systematically analyzed the impact of adjunctive p16 IHC on the accuracy (agreement with reference pathology results) of diagnosing cervical intraepithelial neoplasia of grade 2 or worse (CIN2+) in the United States. Eleven hundred cervical biopsies were divided into 4 sets of 275 cases by stratified randomization. All H&E slides from each set were interpreted by 17 to 18 individual surgical pathologists, for a total of 19,250 reads by 70 surgical pathologists. After a wash-out period and blinding to original results, cases were re-read by the same pathologists using H&E+p16-stained slides. Using expert consensus diagnoses on H&E+p16 as reference, adjunctive p16 IHC use significantly improved diagnostic agreement of surgical pathologists by 4.7% (95% confidence interval [CI], 3.9, 5.4; P<0.0001). This improvement was driven by an increase of 11.5% (95% CI, 9.3, 13.5; P<0.0001) in sensitivity and an increase of 3.0% (95% CI, 2.2, 3.7; P<0.0001) in specificity. Diagnostic performance was significantly increased as well when expert consensus diagnoses established on H&E only was used as reference. Furthermore, interobserver reliability improved significantly from moderate (H&E: κ=0.58) to substantial (H&E+p16: κ=0.73; P<0.0001). Adjunctive use of p16 IHC provides more accurate and reproducible diagnostic results in the interpretation of cervical biopsies, ensuring that more patients are treated correctly without treating more patients.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

Nowadays, anterior cervical artificial disc replacement (ACDR) has achieved favorable outcomes in treatment for patients with single-level cervical spondylosis. However, It is still controversial that whether or not it will become a potent therapeutic alternation in treating 2 contiguous levels cervical spondylosis compared with anterior cervical decompression and fusion (ACDF). Therefore, we conducted a systematic review and meta-analysis to compare the efficacy and safety of ACDR and ACDF in patients with 2 contiguous levels cervical spondylosis. According to the computer-based online search, PubMed, Embase, Web of Science, and Cochrane Library for articles published before July 1, 2017 were searched. The following outcome measures were extracted: neck disability index (NDI), visual analog scale (VAS) neck, VAS arm, Short Form (SF)-12 mental component summary (MCS), SF-12 physical component summary (PCS), overall clinical success (OCS), patient satisfaction (PS), device-related adverse event (DRAE), subsequent surgical intervention (SSI), neurological deterioration (ND), and adjacent segment degeneration (ASD). Methodological quality was evaluated independently by 2 reviewers using the Furlan for randomized controlled trial (RCT) and MINORS scale for clinical controlled trials (CCT). The chi-squared test and Higgin I test were used to evaluate the heterogeneity. A P < .10 for the chi-squared test or I values exceeding 50% indicated substantial heterogeneity and a random-effect model was applied; otherwise, a fixed-effect model was used. All quantitative data were analyzed by the Review Manager 5.2 (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark). Nine RCTs and 2 CCT studies containing 2715 patients were included for this meta-analysis. The pooled analysis indicated that the ACDR group is superior to ACDF in NDI, VAS neck, PCS score, OCS, PS, DRAE, ASD, and SSI. However, the pooled results indicate that there was no significant difference in the ND, VAS arm and in MCS score. The present meta-analysis suggests that for bi-level cervical spondylosis, ACDR appears to provide superior clinical effectiveness and safety effects than ACDF. In the future, more high-quality RCTs are warranted to enhance this conclusion.

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 postural therapy, plaster braces to correct an imbalance in cervical spine biomechanics can prevent deformity development. According to patients' clinical characteristics, choosing individual treatment programs can correct the severe cervical kyphosis and achieve good outcome.

Background Human papillomavirus (HPV) has proven to be the cause of several severe clinical conditions on the cervix, vulva, vagina, anus, oropharynx and penis. Several studies have assessed the costs of cervical lesions, cervical cancer (CC), and genital warts. However, few have been done in Africa and none in Swaziland. Cost analysis is critical in providing useful information for economic evaluations to guide policymakers concerned with the allocation of resources in order to reduce the disease burden. Materials and methods A prevalence-based cost of illness (COI) methodology was used to investigate the economic burden of HPV-related diseases. We used a top-down approach for the cost associated with hospital care and a bottom-up approach to estimate the cost associated with outpatient and primary care. The current study was conducted from a provider perspective since the state bears the majority of the costs of screening and treatment in Swaziland. All identifiable direct medical costs were considered for cervical lesions, cervical cancer and genital warts, which were primary diagnoses during 2015. A mix of bottom up micro-costing ingredients approach and top-down approaches was used to collect data on costs. All costs were computed at the price level of 2015 and converted to dollars ($). Results The total annual estimated direct medical cost associated with screening, managing and treating cervical lesions, CC and genital warts in Swaziland was $16 million. The largest cost in the analysis was estimated for treatment of high-grade cervical lesions and cervical cancer representing 80% of the total cost ($12.6 million). Costs for screening only represented 5% of the total cost ($0.9 million). Treatment of genital warts represented 6% of the total cost ($1million). Conclusion According to the cost estimations in this study, the economic burden of HPV-related cervical diseases and genital warts represents a major public health issue in Swaziland. Prevention of HPV infection with a national HPV immunization programme for pre-adolescent girls would prevent the majority of CC related deaths and associated costs. PMID:28531205

Research investigators often choose to euthanize mice by cervical dislocation (CD) when other methods would interfere with the aims of a research project. Others choose CD to assure death in mice treated with injected or inhaled euthanasia agents. CD was first approved for mouse euthanasia in 1972 by the AVMA Panel on Euthanasia, although scientific assessment of its humaneness has been sparse. Here we compared 4 methods of spinal dislocation--3 targeting the cervical area (CD) and one the thoracic region--in regard to time to respiratory arrest in anesthetized mice. Of the 81 mice that underwent CD by 1 of the 3 methods tested, 17 (21%) continued to breathe, and euthanasia was scored as unsuccessful. Postmortem radiography revealed cervical spinal lesions in 5 of the 17 cases of unsuccessful CD euthanasia. In addition, 63 of the 64 successfully euthanized mice had radiographically visible lesions in the high cervical or atlantooccipital region. In addition, 50 of 64 (78%) mice euthanized successfully had radiographically visible thoracic or lumbar lesions or both. Intentionally creating a midthoracic dislocation in anesthetized mice failed to induce respiratory arrest and death in any of the 18 mice subjected to that procedure. We conclude that CD of mice holds the potential for unsuccessful euthanasia, that anesthesia could be valuable for CD skills training and assessment, and that postmortem radiography has minimal promise in quality-control assessments.

Evidence-based clinical guidelines ensure best practice protocols are available in health care. There is a widespread use of human papillomavirus deoxyribonucleic acid (HPV-DNA) tests in Brazil, regardless of the lack of official guidelines. On behalf of the Brazilian Association for the Lower Genital Tract Pathology and Colposcopy (ABPTGIC, in the Portuguese acronym), a team of reviewers searched for published evidence and developed a set of recommendations for the use of HPV-DNA tests in cervical cancer screening in Brazil. The product of this process was debated and consensus was sought by the participants. One concern of the authors was the inclusion of these tests in the assessment of women with cytologic atypia and women treated for cervical intraepithelial neoplasia (CIN). Testing for HPV is recommended in an organized screening scenario to identify women with precursor lesions or asymptomatic cervical cancer older than 30 years of age, and it can be performed every 5 years. It also has value after the cytology showing atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesions (LSILs) as a triage test for colposcopy, in the investigation of other cytological alterations when no abnormal findings are observed at colposcopy, seeking to exclude disease, or, further, after treatment of high-grade cervical intraepithelial neoplasia, to rule out residual disease.

Stereotactic body radiation therapy (SBRT) administered via a helical tomotherapy (HT) system is an effective modality for treating lung cancer and metastatic liver tumors. Whether SBRT delivered via HT is a feasible alternative to brachytherapy in treatment of locally advanced cervical cancer in patients with unusual anatomic configurations of the uterus has never been studied. A 46-year-old woman presented with an 8-month history of abnormal vaginal bleeding. Biopsy revealed squamous cell carcinoma of the cervix. Magnetic resonance imaging (MRI) showed a cervical tumor with direct invasion of the right parametrium, bilateral hydronephrosis, and multiple uterine myomas. International Federation of Gynecology and Obstetrics (FIGO) stage IIIB cervical cancer was diagnosed. Concurrent chemoradiation therapy (CCRT) followed by SBRT delivered via HT was administered instead of brachytherapy because of the presence of multiple uterine myomas with bleeding tendency. Total abdominal hysterectomy was performed after 6 weeks of treatment because of the presence of multiple uterine myomas. Neither pelvic MRI nor results of histopathologic examination at X-month follow-up showed evidence of tumor recurrence. Only grade 1 nausea and vomiting during treatment were noted. Lower gastrointestinal bleeding was noted at 14-month follow-up. No fistula formation and no evidence of haematological, gastrointestinal or genitourinary toxicities were noted on the most recent follow-up. CCRT followed by SBRT appears to be an effective and safe modality for treatment of cervical cancer. Larger-scale studies are warranted.

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.

To compare the efficacy of tocolytic treatment with indomethacin (I), magnesium sulfate (M) and nifedipine (N) for acute tocolysis in women with advanced cervical dilation (4-6 cm). A single center, randomized trial was carried out involving patients in preterm labor (cervix 1-6 cm). Secondary analysis of women with advanced cervical dilation (cervix 4-6 cm) at 24-32 weeks' gestation who received intravenous M, oral N or I suppositories comprised this study population. Over 38 months, 92 women with advanced cervical dilation were randomized to one tocoloytic type. Days gained in utero (11.7) and percent remaining undelivered at 48 h (60.8%), 72 h (53.1%) and >7 days (38.3%) were similar regardless of tocolytic employed (p = 0.923, 0.968, 0.791, 0.802, respectively). Likewise, gestational age at delivery (30.7 ± 3.2) was similar between groups (p = 0.771). Finally, neonatal statistics were not different when stratified by tocolytic treatment. There were no statistical differences between tocolytics in treating women with advanced cervical dilation. All offered significant days gained in utero after therapy, a high percentage remaining undelivered after 48 or 72 h and after 7 days. It would appear from data that there may be advantages to tocolytic treatment even in women with advanced cervical dilation.

We set out to assess the health care resource utilization and cost of cervical cancer from the perspective of a single-payer health care system. Retrospective observational data for women diagnosed with cervical cancer in British Columbia between 2004 and 2009 were analyzed to calculate patient-level resource utilization patterns from diagnosis to death or 5-year discharge. Domains of resource use within the scope of this cost analysis were chemotherapy, radiotherapy, and brachytherapy administered by the BC Cancer Agency; resource utilization related to hospitalization and outpatient visits as recorded by the B.C. Ministry of Health; medically required services billed under the B.C. Medical Services Plan; and prescriptions dispensed under British Columbia's health insurance programs. Unit costs were applied to radiotherapy and brachytherapy, producing per-patient costs. The mean cost per case of treating cervical cancer in British Columbia was $19,153 (standard error: $3,484). Inpatient hospitalizations, at 35%, represented the largest proportion of the total cost (95% confidence interval: 32.9% to 36.9%). Costs were compared for subgroups of the total cohort. As health care systems change the way they manage, screen for, and prevent cervical cancer, cost-effectiveness evaluations of the overall approach will require up-to-date data for resource utilization and costs. We provide information suitable for such a purpose and also identify factors that influence costs.

Three of the eight recurrences involved lymph nodes exclusively (N), two patients relapsed exclusively at the primary tumour site (T) and three patients presented local and lymph node recurrence (T and N). Treatment consisted of salvage total laryngectomy with bilateral cervical lymph node dissection in three cases, bilateral cervical lymph node dissection and sensitized radiotherapy in two cases, exclusive chemotherapy in one case, cervical lymph node dissection and cervical radiotherapy in one case. The last patient with recurrence died prior to salvage therapy. The larynx preservation rate was 94.9%. In comparison with the literature, treatment of stage T1-T2N0M0 glottic cancer by exclusive radiotherapy gives very good results, with a larynx preservation rate of 95%.

Background This review aimed to synthesize and analyze the diagnostic accuracy and the likelihood of providing correct treatment of the syndromic approach Vaginal Discharge Flowchart in managing cervical infections caused by Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT), and vaginal infections caused by Trichomonas vaginalis (TV) and Bacterial vaginosis (BV) and Candida albicans. This review will inform updating the WHO 2003 guidelines on Vaginal Discharge syndromic case management. Methods A systematic review was conducted on published studies from 01-01-2000 to 30-03-2015 in multiple databases. Studies evaluating the diagnostic accuracy and validation of the WHO Vaginal Discharge Flowchart were included. Validation parameters including sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) and the 95% confidence intervals for the different types of the flowchart were taken as outcomes, re-calculated, and analysed using a fixed model meta-analysis for data pooling. The level of agreement between the index and reference test were determined by the Cohen’s Kappa co-efficiency test. Each individual study was assessed on quality using the QUADAS-2 tool. Findings The search yielded 2,845 studies of which 16 met the eligibility criteria for final analysis. The diagnostic performance to identify cervical infections was low and resulted in a high proportion of over and missed treatment. The four flowcharts had a sensitivity between 27.37% in history and risk assessment and 90.13% with microscopy, with the inverse in specificity rates. The treatment performances between the flowcharts were inconsistent. The same applies to the use of vaginal discharge flowchart for treating vaginal infections. For vaginal infections the vaginal discharge flowchart had a good performance in flowchart 3 with 91.68% of sensitivity; 99.97% specificity; 99.93% PPV and 0.02% who missed their treatment and 8.32% of women who were over treated by the vaginal discharge flowchart Conclusion The vaginal discharge flowchart should focus on management of vaginal infection. It could be used as an intermediate approach for cervical infections for sex workers until a point of care test is available in resource poor settings. PMID:27706174

Head and neck injuries, the leading cause of death for children in the U.S., are difficult to diagnose, treat, and prevent because of a critical void in our understanding of the biomechanical response of the immature cervical spine. The objective of this study was to investigate the functional and failure biomechanics of the cervical spine across multiple axes of loading throughout maturation. A correlational study design was used to examine the relationships governing spinal maturation and biomechanical flexibility curves and tolerance data using a cadaver human in vitro model. Eleven human cadaver cervical spines from across the developmental spectrum (2-28 years) were dissected into segments (C1-C2, C3-C5, and C6-C7) for biomechanical testing. Non-destructive flexibility tests were performed in tension, compression, flexion, extension, lateral bending, and axial rotation. After measuring their intact biomechanical responses, each segment group was failed in different modes to measure the tissue tolerance in tension (C1-C2), compression (C3-C5), and extension (C5-C6). Classical injury patterns were observed in all of the specimens tested. Both the functional (p<0.014) and failure (p<0.0001) mechanics exhibited significant relationships with age. Nonlinear flexibility curves described the functional response of the cervical spine throughout maturation and elucidated age, spinal level, and mode of loading specificity. These data support our understanding of the child cervical spine from a developmental perspective and facilitate the generation of injury prevention or management schema for the mitigation of child spine injuries and their deleterious effects.
