Cervical screening programme: HPV triage and test of cure protocol

Testing for high-risk human papillomavirus (HR-HPV) as triage and test of cure was introduced into the Northern Ireland Cervical Screening Programme on Monday 28 January 2013. This policy change will significantly alter the screening pathway for women with a mild dyskaryosis or borderline smear result. The link between HR-HPV infection and the development of cervical cancer has now been clearly established, with almost 100% of cervical cancers containing HPV DNA. Women with no evidence of HR-HPV infection are extremely unlikely to develop cervical cancer in the short to medium term. HPV triage is the process whereby HR-HPV testing is used to manage women with low grade cervical abnormalities. Only 15-20% of women with a borderline or mild smear result have a significant abnormality that needs treatment. HR-HPV testing is effective in identifying which women may need treatment and allows colposcopy resources to be allocated more effectively.The test of cure process is being introduced because it is now known that women with a normal or low grade smear test, and who are HR-HPV negative at six months after treatment, are at very low risk of residual disease. These women do not need to be recalled for another screening appointment for three years.The test of cure process means all post-treatment smears (at six months) that are reported as normal, borderline or mild dyskaryosis will be tested for HR-HPV. Those women who are HR-HPV positive will remain at colposcopy. HR-HPV negative women can be safely returned to recall in three years. It is estimated that the HR-HPV test of cure will allow approximately 80% of women who have been through treatment to avoid undergoing annual smear tests. This flowchart poster outlines the new triage and test of cure process. It was distributed to all GPs in Northern Ireland and is available to download as a PDF from this website.�

Northern Ireland cervical screening programme: information for primary care and smear takers

From January 2011, the Northern Ireland cervical screening programme no longer invited women aged under 25 to attend for screening. In addition, the screening interval for women aged 25-49 was reduced to every three years.This�booklet describes the rationale for the change in policy so that primary care staff and smear takers can provide appropriate and accurate advice to patients.

Evaluation of the GlideScope (R) for tracheal intubation in patients with cervical spine immobilisation by a semi-rigid collar

Application of cervical collars may reduce cervical spine movements but render tracheal intubation with a standard laryngoscope difficult if not impossible. We hypothesised that despite the presence of a Philadelphia Patriot (R) cervical collar and with the patient's head taped to the trolley, tracheal intubation would be possible in 50 adult patients using the GlideScope (R) and its dedicated stylet. Laryngoscopy was attempted using a Macintosh laryngoscope with a size 4 blade, and the modified Cormack-Lehane grade was scored. Subsequently, laryngoscopy with the GlideScope was graded and followed by tracheal intubation. All patients' tracheas were successfully intubated with the GlideScope. The median (IQR) intubation time was 50 s (43-61 s). The modified Cormack-Lehane grade was 3 or 4 at direct laryngoscopy. It was significantly reduced with the GlideScope (p < 0.0001), reaching grade 2a in most patients. Tracheal intubation in patients wearing a semi-rigid collar and having their head taped to the trolley is possible with the help of the GlideScope.

HPV vaccination: the beginning of the end of cervical cancer? - A Review

Human papillomavirus (HPV) is responsible for all cases of cervical cancer, as well as a great percentage of other anogenital tumors and oropharyngeal tumors. Since the main etiologic factor for these diseases is a virus, prophylactic measures are the best way to reduce the burden caused by the infection and associated disease. This review brings up to date information on the two commercially available prophylactic HPV vaccines against HPV, as well as presenting the ongoing research on HPV peptide, protein and dendritic cell based therapeutic vaccines.

Ossification du ligament commun cervical postérieur : coexistence de spondylarthrite et d'une hyperostose idiopathique diffuse du squelette

Introduction: L'ossification du ligament commun vertébral postérieur (LCVP) est une hyperostose prédominant au rachis cervical, associée à différentes pathologies constructrices comme l'arthrose, la maladie de Forestier (ou DISH : Diffuse Idiopathic Squeletal Hyperostosis) ou les spondylarthrites (1). Nous rapportons le cas d'une patiente avec ossification cervicale du LCVP, avec coexistence de DISH et de spondylarthrite.Observation: Patiente de 55 ans, d'origine Irakienne, qui présente depuis l'âge de 40 ans des lombalgies et des talalgies attribuées initialement à un métier physique. En 2008, apparait une cervicobrachialgie C6 gauche. L'IRM cervicale retrouve plusieurs hernies discales (C5-C6 et C6-C7 gauches) avec un canal cervical étroit constitutionnel et une ossification du LCVP cervical. Cette ossification est attribuée à un DISH (Figure1). L'échec du traitement conservateur de la névralgie et la menace neurologique de l'ossification du LCVP conduisent en 2010 à une laminectomie C3-C6 avec fixation postérieure (figure 2). En 2011, la patiente consulte en raison de la persistance de cette névralgie, ainsi que pour des lombalgies inflammatoires. La coexistence de ces symptômes inflammatoires et de l'ossification du LCVP nous incite à réaliser une IRM des sacroiliaques qui retrouve une sacroiliite bilatérale (figure 3). Le diagnostic de spondylarthrite HLA B27 négative est retenu devant l'association des signes cliniques et radiologiques. L'étiologie précise quant à l'origine de l'ossification du LCVP reste incertaine, néanmoins un traitement spécifique de la spondylarthopathie est proposé.Discussion: L'ossification du ligament vertébral commun postérieur est une hyperostose dont les principales causes sont le DISH et les spondylarthrites. On retrouve une ossification du ligament commun vertébral, qu'il soit lombaire, cervical ou dorsal, dans 10 à 50 % des DISH, et 3.5 à 30% des spondylarthrites. 4 types d'ossification du LCVP sont décrites : continue, segmentaire, mixte ou circonscrite. Selon Resnick, le DISH se différencie de la spondylarthrite par la présence d'ossifications antérolatérales d'au moins 4 vertèbres contigües sans érosion des sacroiliaques. Cependant on retrouve dans la littérature quelques cas décrivant la coexistence des 2 pathologies. Récemment, Kim et al. Ont rapporté un cas similaire à notre patiente, avec ossification du LCVP cervical et coexistence de DISH et de spondylarthrite (2).Conclusion: Devant la présence d'une ossification du ligament vertébral commun postérieur cervical, il convient de rechercher des signes de DISH et de spondylarthrite, car leur coexistence est possible. La prévalence exacte de cette association reste encore à déterminer.

Evaluation of monoenergetic imaging to reduce metallic instrumentation artifacts in computed tomography of the cervical spine.

OBJECT Monoenergetic imaging with dual-energy CT has been proposed to reduce metallic artifacts in comparison with conventional polychromatic CT. The purpose of this study is to systematically evaluate and define the optimal dual-energy CT imaging parameters for specific cervical spinal implant alloy compositions. METHODS Spinal fixation rods of cobalt-chromium or titanium alloy inserted into the cervical spine section of an Alderson Rando anthropomorphic phantom were imaged ex vivo with fast-kilovoltage switching CT at 80 and 140 peak kV. The collimation width and field of view were varied between 20 and 40 mm and medium to large, respectively. Extrapolated monoenergetic images were generated at 70, 90, 110, and 130 kiloelectron volts (keV). The standard deviation of voxel intensities along a circular line profile around the spine was used as an index of the magnitude of metallic artifact. RESULTS The metallic artifact was more conspicuous around the fixation rods made of cobalt-chromium than those of titanium alloy. The magnitude of metallic artifact seen with titanium fixation rods was minimized at monoenergies of 90 keV and higher, using a collimation width of 20 mm and large field of view. The magnitude of metallic artifact with cobalt-chromium fixation rods was minimized at monoenergies of 110 keV and higher; collimation width or field of view had no effect. CONCLUSIONS Optimization of acquisition settings used with monoenergetic CT studies might yield reduced metallic artifacts.

High prevalence and low E6 genetic variability of human papillomavirus 58 in women with cervical cancer and precursor lesions in Southeast Mexico

Infection with some genotypes of human papillomavirus (HPV) is the most important risk factor associated with cervical cancer (CC). Throughout the world, HPV type 58 prevalence varies from one region to another; it is higher in women from certain countries in Asia and Latin America, such as China and Mexico. Although intratypic variants have been reported on a few occasions, our knowledge about HPV 58 genetic variation remains limited. Therefore, this work aims to (i) determine the prevalence of HPV type 58 amongst Mexican women with invasive CC or precursor lesions and (ii) identify HPV 58 sequence variants. One hundred and forty five colposcopy clinic patients were studied. Genotyping of HPV 16, 18 and 58 was determined by specific nested PCR and HPV 58 variants were detected by direct sequencing. The general prevalence of HPV was 51.7% (75/145). HPV 16 was found in 30.6% (23/75) and HPV 58 in 24% (18/75) of the patients. HPV 18 was not identified in patients with cervical intraepithelial neoplasia (CIN) grade I; it was only found in those with CIN II, with a prevalence of 6.8% (3/44). In patients with CC, the prevalence of HPV 16 and 58 was 78.9%. Regarding HPV 58 variants, 94.4% of the HPV 58 sequences were identical to the prototype strain, whereas one sample showed changes at a single nucleotide. This study demonstrates a high prevalence of HPV 58 and a low genetic variability of E6 sequences amongst Mexican colposcopy patients.

Cervical myelopathy in hereditary multiple exostoses.

Spinal cord compression due to cervical exostoses is a rare but recognized complication of hereditary multiple exostosis (HME), an autosomal dominant disorder. This disease, also called multiple osteochondromatosis, is characterised by osteocartilaginous exostoses, typically involving the juxtaepiphyseal regions of long bones. Complications such as transformation to sarcoma (1 to 5%) or neurological compression (of the spinal cord, 1 to 9%) can arise during the course of the disease. We report the case of a 64-year-old man with progressive difficulties in walking over many years, ascribed to congenital rachitism. A diagnosis of HME was not made until late in the disease course. Investigations revealed cervical myelopathy due to vertebral exostosis as well as multiple exostoses in other sites. His gait was not improved after surgical decompression. A better knowledge of this disease could have prevented this neurological complication.

Evaluation of the GlideScope (R) for tracheal intubation in patients with cervical spine immobilization by a semi-rigid collar

Background: In patients with cervical spine injury, a cervical collar may prevent cervical spine movements but renders tracheal intubation with a standard laryngoscope difficult if not impossible. We hypothesized that despite the presence of a semi-rigid cervical collar and with the patient's head taped to the trolley, we would be able to intubate all patients with the GlideScopeR and its dedicated stylet. Methods: 50 adult patients (ASA 1 or 2, BMI ≤35 kg/m2) scheduled for elective surgical procedures requiring tracheal intubation were included. After standardized induction of general anesthesia and neuromuscular blockade, the neck was immobilized with an appropriately sized semi-rigid Philadelphia Patriot® cervical collar, the head was taped to the trolley. Laryngoscopy was attempted using a Macintosh laryngoscope blade 4 and the modified Cormack Lehane grade was noted. Subsequently, laryngoscopy with the GlideScopeR was graded and followed by oro-tracheal intubation. Results: All patients were successfully intubated with the GlideScopeR and its dedicated stylet. The median intubation time was 50 sec [43; 61]. The modified Cormack Lehane grade was 3 or 4 at direct laryngoscopy. It was significantly reduced with the GlideScopeR (p <0.0001), reaching 2a in most of patients. Maximal mouth opening was significantly reduced with the cervical collar applied, 4.5 cm [4.5; 5.0] vs. 2.0 cm [1.8; 2.0] (p <0.0001). Conclusions: The GlideScope® allows oro-tracheal intubation in patients having their cervical spine immobilized by a semi-rigid collar and their head taped to the trolley. It furthermore decreases significantly the modified Cormack Lehane grade.

Clinical performance of cervical restorations: a meta-analysis.

OBJECTIVES: To carry out a meta-analysis in order to assess the influencing factors on retention loss and marginal discoloration of cervical restorations made of composites and glass ionomer (derivates). METHODS: The literature was searched for prospective clinical studies on cervical restorations with an observation period of at least 18 months. RESULTS: Fifty clinical studies involving 40 adhesive systems matched the inclusion criteria. On average, 10% of the cervical fillings were lost and 24% exhibited marginal discoloration after 3 years. The variability ranged from 0% to 50% for retention loss and from 0% to 74% for marginal discoloration. Hardly any secondary caries was detected. When linear mixed models with a study and experiment effect were used, the analysis revealed that the adhesive/restorative class had the most significant influence, with 2-step self-etching adhesive systems performing best and 1-step self-etching adhesive systems performing worst; 3-step etch-and-rinse systems, glass ionomers/resin-modified glass ionomers, 2-step etch-and-rinse systems and polyacid-modified resin composites were ranked in between. Restorations placed in teeth whose dentin/enamel had been prepared/roughened showed a statistically significant higher retention rate than those placed in teeth with unprepared dentin (p<0.05). Beveling of the enamel and the type of isolation used (rubberdam/cotton rolls) had no significant influence. SIGNIFICANCE: The clinical performance of cervical restorations is significantly influenced by the type of adhesive system used and/or the adhesive class to which the system belonged and whether the dentin/enamel is prepared or not. 2-Step self-etching- and 3-step etch&rinse systems shall be chosen over 1-step self-etching systems and glass ionomer derivates. The dentin (and enamel) surface shall be roughened before placement of the restoration.
