Percutaneous C-arm-guided Wide Bore Needle Biopsy for Intraosseous Spinal Lesions
Authors: Basu Saumyajit , Tikoo Agnivesh , Malik Farid H , Ghosh Jay Deep , Jain Mantu , Sarangi Trinanjan 
Published: February 2015

ABSTRACT

Study design
Retrospective analysis of data of those patients who underwent a percutaneous transpedicular biopsy at our hospital was done. All patients had a bony lesion in a vertebra (thoracic, lumbar, sacrum) without a soft tissue component around the bone and neurodeficit.

Objective
To analyze the role of percutaneous wide bore needle biopsy in vertebral lesions without any soft tissue component.

Summary of background data
Adequate treatment of spinal lesions requires formulation of diagnosis-best achieved by a tissue biopsy when all attempts at diagnosis fail by noninvasive methods. Percutaneous CT guided fine needle biopsy is technically difficult in intraosseous lesions leading to frequent inconclusive results and hence the necessity of wide bore needle biopsy.

Materials and methods
Retrospective analysis of data of 26 patients with mean age of 58.8 years who underwent a percutaneous transpedicular biopsy at our hospital was done. All patients had a bony lesion in a vertebra (thoracic, lumbar, saccrum) without a soft tissue component around the bone and neurodeficit. The procedure was done under local anesthesia with sedation.

Results
Positive diagnosis was achieved in 23 out of 26, i.e. 88.4% of cases (adequacy). Out of 26, there were 13 cases of malignancy (50%), 8 cases of tuberculosis (30.7%), 2 cases of osteoporosis (7.6%) and biopsy was inconclusive in 3 (11.5%) cases. Of the 13 malignancies, 7 cases were of metastasis (53.8%), 5 cases of plasmocytoma (38.4%) and 1 case of lymphoma (7.6%).

Conclusion
Percutaneous biopsy under fluoroscopic guidance by transpedicular approach is quite safe and gives high adequacy (88.4%) without significant complications that are associated with open and paraspinal techniques.

Published: February 2015

ABSTRACT
Journal club (JC) is an effective and valuable tool in medical education. Critical reasoning and evidence based medicine practice are core competencies required by medical professionals. In times of today journal club offers several advan- tages, e.g. update with current literature, promote evidencebased medicine, demonstrate continuing medical education, learn critical appraisal skills and promote social interaction and debate. However, this tool remains largely underutilized. Practice of inappropriate methodology results in failure to achieve the intended outcomes. This report attempts to track the history of journal club, its types, current innovations made and role in medical education. It explores the potential utilization of this tool in times to come.

Traumatic Pseudoaneurysm of Internal Carotid Artery presenting as Intractable Epistaxis in a Case of Maxillary Fracture
Authors: Kumar Ajay , Rattan Vidya , Kumar Dinesh , Sahu Gyana Ranjan , Mukherjee KK 
Published: February 2015

ABSTRACT
Traumatic pseudoaneurysm of internal carotid artery is a rare complication of injury after craniomaxillofacial trauma. Delayed recurrent epistaxis after head and facial trauma is the most distinctive manifestation of traumatic internal carotid artery pseudoaneurysm. Epistaxis due to pseudoaneurysm of internal carotid artery is difficult to control, and may lead to hemor- rhagic shock or asphyxia and thus seriously threatens life. The purpose of this paper is to present a rare case of recurrent epistaxis secondary to ICA pseudoaneurysm following blunt maxillofacial trauma. Endovascular stenting was performed and the recurrent epistaxis was successfully arrested.

Romantic Irony in the Short Fiction of Rebecca Harding Davis
Authors: WEST MICHAEL D. 
Published: February 2015

AbstractAs the author of some 275 short stories, over a dozen novels, and hundreds of juvenile stories and journalistic essays, Rebecca Harding Davis’ prolific output spanning more than five decades naturally invites—and challenges—categorization. Although her novels were well-received, it was the short stories she published chiefly in periodicals, with only one collection in book form, “that earned her greatest critical praise.” Romanticism, sentimentalism, regionalism, realism, and naturalism are all justifiably invoked to explain aspects of her oeuvre, with the palm probably going to realism. But in her pioneering study Sharon Harris claimed that if Davis was a realist, she was often an ironic realist; and more recently Harris has acknowledged that pigeonholing her fiction as “realism” can be misleading since she “was much more diverse in her choices of genres” than that label suggests.1 It is with some trepidation that one ventures to add another to the heap of competing labels, but this paper will argue that many of her stories exhibit the traits commonly categorized as romantic irony. As G. R. Thompson and West have argued, a predilection for romantic irony was shared by all the major figures of American Romanticism and is to some extent at odds with realism
Crafting the Sea: Romance and Realism in Jack London’sMartin Eden
Authors: DUNEER ANITA 
Published: February 2015

AbstractPublished between Jack London’s sea novels, The Sea-Wolf (1904) and The Mutiny of the Elsinore (1913), the autobiographically-inspired novel Martin Eden (1909) is not set at sea—with the exception of Martin’s suicide in the last chapter. Perhaps since the novel is primarily set on land, the importance of the sea to the artistic identity of London and his character Martin have generally been overlooked. The novel is flooded with language and imagery of the sea. The sea colors Martin’s imagination, the narrator makes frequent use of nautical metaphors, and the conventions of maritime literature inform the overall structure of the novel. Martin Eden reflects the sea’s influence on London, who was an avid reader of maritime literature and a seasoned sailor. London had sailed in San Francisco Bay in his youth as an oyster pirate and member of the California Fish Patrol, and as a young man on a sealing expedition aboard the Sophia Sutherland, an adventure that provided raw material for The Sea-Wolf. Martin Eden was composed at sea, begun during London’s voyage to the South Seas on his fifty-seven-foot ketch the Snark with his wife Charmian, and completed on the Mariposa, the steamship that transported the Londons back to Tahiti where they had left the Snark during a business trip to San Francisco. The sea is as integral to Martin’s character as it is for London’s self-identity. Thus by reading Martin Eden as a novel of the sea, we can better understand London’s social and aesthetic navigation of romance and realism, in a work both influenced by and contributing to the maritime literary tradition.
Anatomic Distribution of Sessile Serrated Adenoma/Polyp With and Without Cytologic Dysplasia
Authors: Yang Juliana F. , Tang Shou-Jiang , Lash Richard H. , Wu Ruonan , Yang Qinghua 
Published: February 2015

Context
Sessile serrated adenomas/polyps (SSA/Ps) have been increasingly studied during the last 10 years. However, their detailed anatomic distribution pattern has not been studied, especially given newer (broader) criteria for the diagnosis.

Objectives
To characterize the anatomic distribution of SSA/P with and without cytologic dysplasia and to assess the demographics of these patients in a nationwide database.

Design
We retrospectively analyzed the database of Miraca Life Sciences Research Institute for a 1-year period. Patients with a diagnosis of SSA/P, SSA/P with low-grade cytologic dysplasia (SSA/P-LGD), SSA/P with high-grade cytologic dysplasia (SSA/P-HGD), or SSA/P with adenocarcinoma (SSA/P-ACA) were retrieved, and patients' age, sex, and specific anatomic location were analyzed.

Results
A total of 11 201 patients were identified, of which 10 646 (95.0%) had SSA/P, 514 (4.6%) had SSA/P-LGD, 39 (0.35%) had SSA/P-HGD, and 2 (0.018%) had SSA/P-ACA. All SSA/Ps and more advanced lesions were significantly more common in the proximal colon—SSA/P (61.2%), SSA/P-LGD (61.2%), SSA/P-HGD (80%), and SSA/P-ACA (100%)—than in either the transverse (18.8%, 17.8%, 10.0%, and 0%, respectively) or the distal (19.9%, 21.0%, 10.0%, and 0%, respectively) colon, P &lt; .001. Sessile serrated adenoma/polyp with cytologic dysplasia was most commonly found in the ascending colon (LGD, 31.6%) and cecum (HGD, 37.5%). Advanced SSA/Ps were disproportionally more common among older women.

Conclusions
Sessile serrated adenomas/polyps with and without cytologic dysplasia and carcinoma are predominantly found in the cecum and ascending colon, whereas there is low prevalence in both the transverse and distal colon. Confirmation of previously published data regarding demographics of advanced lesions among a different cohort and including newer (broader) criteria suggests these criteria are valid.

Au sein de la production artistique des cinéastes en Amérique du Nord, dans une industrie encore dominée par des voix et des regards masculins, un nombre croissant de récits mis en scène par des réalisatrices « multiculturelles nord-américaines » est apparu à partir des années 90. Cette décennie marque ainsi l’émergence des premiers documentaires et de quelques longs métrages réalisés par des femmesen diasporatelles que la cinéaste féministe montréalaise Eisha Marjara.

A parameterization of gravity waves emitted by fronts and jets
Authors: de la Cámara A. , Lott F. 
Published: February 2015

AbstractBased on the theoretical and experimental facts that gravity waves (GWs) can be spontaneously emitted during the evolution of a near‐balanced flow, a stochastic parameterization of GWs linked to fronts and jets is proposed. Although the spontaneous adjustment theory used predicts “exponentially” small GW fields, it is shown that it is sufficient to produce realistic GW drag at mesospheric levels. Off‐line tests using reanalyzed meteorological fields are conducted and show that the GWs emitted present a strong annual cycle following that of the sources. Also, the GW momentum fluxes in the lower stratosphere are qualitatively realistic in terms of intermittency. Online tests in a middle atmosphere general circulation model show that the scheme can potentially perform as well as highly tuned existing GW schemes.

Virtual taphonomy: A new method integrating excavation and postprocessing in an archaeological context
Authors: Wilhelmson Helene , Dell'Unto Nicoló 
Published: February 2015

ABSTRACTThe objective of this paper was to integrate excavation and post‐processing of archaeological and osteological contexts and material to enhance the interpretation of these with specific focus on the taphonomical aspects. A method was designed, Virtual Taphonomy, based on the use and integration of image‐based 3D modeling techniques into a 3D GIS platform, and tested on a case study. Merging the 3D models and a database directly in the same virtual environment allowed the authors to fully integrate excavation and post‐processing in a complex spatial analysis reconnecting contexts excavated on different occasions in the field process. The case study further demonstrated that the method enabled a deeper understanding of the taphonomic agents at work and allowed the construction of a more detailed interpretation of the skeletal remains than possible with more traditional methods. The method also proved to add transparency to the entire research process from field to post‐processing and interpretation. Other benefits were the timesaving aspects in documentation, not only in the excavation process but also in post‐processing without creating additional costs in material, as the equipment used is available in most archaeological excavations. The authors conclude that this methodology could be employed on a variety of investigations from archaeological to forensic contexts and add significant value in many different respects (for example, detail, objectivity, complexity, time‐efficiency) compared to methods currently used.

Enantioselective Desymmetrization of Prochiral Cyclohexanones by Organocatalytic Intramolecular Michael Additions to α,β‐Unsaturated Esters
Authors: Gammack Yamagata Adam D. , Datta Swarup , Jackson Kelvin E. , Stegbauer Linus , Paton Robert S. , Dixon Darren J. 
Published: February 2015

AbstractA new catalytic asymmetric desymmetrization reaction for the synthesis of enantioenriched derivatives of 2‐azabicyclo[3.3.1]nonane, a key motif common to many alkaloids, has been developed. Employing a cyclohexanediamine‐derived primary amine organocatalyst, a range of prochiral cyclohexanone derivatives possessing an α,β‐unsaturated ester moiety linked to the 4‐position afforded the bicyclic products, which possess three stereogenic centers, as single diastereoisomers in high enantioselectivity (83–99 % ee) and in good yields (60–90 %). Calculations revealed that stepwise CC bond formation and proton transfer via a chair‐shaped transition state dictate the exclusive endo selectivity and enabled the development of a highly enantioselective primary amine catalyst.
Charge Separation in Graphene‐Decorated Multimodular Tris(pyrene)–Subphthalocyanine–Fullerene Donor–Acceptor Hybrids
Authors: KC Chandra B. , Lim Gary N. , D'Souza Francis 
Published: February 2015

AbstractA new approach to probe the effect of graphene on photochemical charge separation in donor–acceptor conjugates is devised. For this, multimodular donor–acceptor conjugates, composed of three molecules of pyrene, a subphthalocyanine, and a fullerene C60 ((Pyr)3SubPc‐C60), have been synthesized and characterized. These systems were hybridized on few‐layer graphene through π–π stacking interactions of the three pyrene moieties. The hybrids were characterized using Raman, HRTEM, and spectroscopic and electrochemical techniques. The energy levels of the donor–acceptor conjugates were fine‐tuned upon interaction with graphene and photoinduced charge separation in the absence and presence of graphene was studied by femtosecond transient absorption spectroscopy. Accelerated charge separation and recombination was detected in these graphene‐decorated conjugates suggesting that they could be used as materials for fast‐responding optoelectronic devices and in light energy harvesting applications.
