Production of full-length cDNA sequences by sequencing and analysis of expressed sequence tags from Schistosoma mansoni

The number of sequences generated by genome projects has increased exponentially, but gene characterization has not followed at the same rate. Sequencing and analysis of full-length cDNAs is an important step in gene characterization that has been used nowadays by several research groups. In this work, we have selected Schistosoma mansoni clones for full-length sequencing, using an algorithm that investigates the presence of the initial methionine in the parasite sequence based on the positions of alignment start between two sequences. BLAST searches to produce such alignments have been performed using parasite expressed sequence tags produced by Minas Gerais Genome Network against sequences from the database Eukaryotic Cluster of Orthologous Groups (KOG). This procedure has allowed the selection of clones representing 398 proteins which have not been deposited as S. mansoni complete CDS in any public database. Dedicated sequencing of 96 of such clones with reads from both 5' and 3' ends has been performed. These reads have been assembled using PHRAP, resulting in the production of 33 full-length sequences that represent novel S. mansoni proteins. These results shall contribute to construct a more complete view of the biology of this important parasite.

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.

Full-length genomic sequence of hepatitis B virus genotype C2 isolated from a native Brazilian patient

The hepatitis B virus (HBV) is among the leading causes of chronic hepatitis, cirrhosis and hepatocellular carcinoma. In Brazil, genotype A is the most frequent, followed by genotypes D and F. Genotypes B and C are found in Brazil exclusively among Asian patients and their descendants. The aim of this study was to sequence the entire HBV genome of a Caucasian patient infected with HBV/C2 and to infer the origin of the virus based on sequencing analysis. The sequence of this Brazilian isolate was grouped with four other sequences described in China. The sequence of this patient is the first complete genome of HBV/C2 reported in Brazil.
