Towards High-power Single-cycle THz Laser for Initiating High-field-sensitive Phenomena
Authors: Ruchert Clemens , Ardana Fernando , Trisorio Alexandre , Vicario Carlo , Hauriab Christoph P.
Published: June 2011

Powerful THz radiation confined in one field period or less is an adequate tool for triggering nonlinear actions. We show results towards the realization of a tunable high-power THz source based on a laser-driven frequency conversion scheme in plasma and nonlinear crystals. A powerful
THz source in combination with the future X-ray Free Electron Laser facility in Switzerland (SwissFEL) holds promise for exciting experiments in a variety of different research areas.
Time-Resolved Electronic Spectra with Efficient Quantum Dynamics Methods
Authors: Wehrle Marius , Šulc Miroslav , Vaníček Jiří
Published: June 2011

We explore three specific approaches for speeding up the calculation of quantum time correlation functions needed for time-resolved electronic spectra. The first relies on finding a minimum set of sufficiently accurate electronic surfaces. The second increases the time step required
for convergence of exact quantum simulations by using different split-step algorithms to solve the time-dependent Schrödinger equation. The third approach lowers the number of trajectories needed for convergence of approximate semiclassical dynamics methods.
What difference does 'difference' make? A discussion with ethnic minority students about their learning experience in higher education
Authors: Housee Shirin
Published: June 2011

This article explores the everyday experiences of minority ethnic students at a university in the West Midlands. Based on interviews with 23 second-level students taking Sociology modules, it seeks to highlight the key social, personal and pedagogic issues for this group of minority ethnic students and to deepen understandings of cultural identity and exchange on campus. The students' multiple narratives and voices are central to the article, as is the possibility that there are multiple ways of experiencing teaching and learning at a university.
Ontotropology: Disfiguration and Unreadability in James Joyce's Ulysses
Authors: Spunt Nicola Ivy
Published: June 2011

This paper explores how figures of temporality, disfiguration and orgasm in the ‘Nausicaa’ episode of Joyce's Ulysses come together to allegorise unreadability. I argue that the text's invocation of a ‘contretemps’ to figure a scene of indigestion elicits a temporality of shock, producing a counternarrative that thwarts (vomits up) the ostensible readability it purports. Moreover, the principles of ideality and transparency commonly associated with the sentimental mode are countervailed by the episode's transgressive rhetorical shocks: a public display of onanistic activity and the revelation of Gerty's ‘lame leg’. The text's renderings of Gerty's disfiguration as well as the orgasmic both work to allegorise unreadability; I also suggest that they ramify ontologically. Drawing on Jacques Derrida and Jean-Luc Nancy, I investigate the co-articulation of ontology and tropology in ‘Nausicaa’ to adumbrate a theory of ‘ontotropology’ — the figuration of ontology as an undecidable condition of tropological surfeit born out of temporal disjunction.
Murmurs, Stutters, Foreign Intonations: Melville's Unreadables
Authors: Jonik Michael
Published: June 2011

The ‘notorious unreadability’ of Bartleby can be summarised by Derrida's brief provocation: ‘Is it not as if Bartleby were also speaking “in tongues”?’ Here, the modality of Melville's unreadability is not only Bartleby's indeterminate sentence, but how Melville's characters more generally become processes of depersonalisation or deidentification, such that their ‘characteristics’ resonate in the circumambient air of Melville's writing. This process is thematised in Deleuze's writing on Melville in terms of a vibration or a murmur, a thematisation which Rancière has recently critiqued.

Published: June 2011

Résumé L’auteur propose ici une analyse psychodynamique du cas clinique d’une jeune fille anorexique-boulimique de 16 ans hospitalisée dans un service de psychiatrie pour adolescents et jeunes adultes. Le matériel clinique présenté a été recueilli pendant plusieurs mois dans le cadre d’entretiens individuels et familiaux, d’un groupe de parole, et de « repos accompagnés ». Cette analyse repose sur une hypothèse directrice : le syndrome anorexique- boulimique constitue une mise en acte d’un fantasme d’incorporation qui peut être interprété à la fois sur un axe œdipien et sur un axe narcissico- mélancolique. Au cœur de la problématique sous-jacente à cette étude de cas se trouve la question de l’articulation de l’acte et du fantasme dans les troubles du comportement alimentaire et, au-delà, dans tous les agirs addictifs.

Job Embeddedness Factors and Retention of Nurses With 1 to 3 Years of Experience
Authors: Halfer Diana
Published: June 2011

An aging work force, predictions of job growth in health care, and an eventual economic recovery suggest that the current reprieve from the national nursing shortage is temporary. New graduate nurses are an important part of the work force and are needed to replace nurses who will retire in the next decade. Organizational leaders can address the forecasted work force demand by proactively investing in programs for workplace development and retention. Recent literature reports an increased focus on understanding the work experience and career support needed for new graduate nurses. Several studies report improvements in job satisfaction and retention after implementation of structured mentoring programs for new graduate nurses. However, despite successful transition programs, turnover for these same nurses after 1 to 3 years of organizational tenure remains high. Studying factors that contribute to retention and supporting careers beyond the first year of practice may have a significant effect on improving retention and will contribute new knowledge to the nursing literature. This study, undertaken at a Midwestern pediatric academic medical center, examined job factors and career development support that lead to retention of nurses with 1 to 3 years of experience. Understanding these issues may guide nursing leaders and staff development educators in investing in focused retention and career development plans during an economic recession.

Driving and Dementia: What Nurses Need to Know
Authors: Flanagan Nina M.
Published: June 2011

Driving is considered an instrumental activity of daily living and, for many older adults, is also associated with the ability to maintain independence. The diagnosis of dementia, distressing on its own, paired with the threat to driving independence, makes this a difficult issue for patients, families, and clinicians. The purpose of this article is to provide a brief overview of the current research regarding driving safety and dementia, guidelines that can be used to assess driving risk, and counseling tips for patients and families regarding driving safety.
Washington State Death with Dignity Act: Implications for Long-Term Care
Authors: Feldt Karen S. , Bond Gail E. , Jacobson Dana , Clymin Janine
Published: June 2011

The Washington Death with Dignity Act (DWDA) allows competent, terminally ill adults to request a lethal dose of medication from a physician. The purpose of this study was to explore knowledge of Directors of Nursing (DONs) in long-term care (LTC) and assisted living facilities regarding the DWDA. Findings of the survey provide insight into DONs’ understanding of the law and whether they have provided staff education regarding how to respond to resident requests. This survey, although limited by sample size, may provide guidance for policy development in LTC settings regarding similar laws.
Subvastus and Medial Parapatellar Approaches in TKA: Comparison of Functional Results
Authors: Dutka Julian , Skowronek Michal , Sosin Pawel , Skowronek Pawel
Published: June 2011

The purpose of this study was to compare the clinical results of total knee arthroplasty (TKA) in the early and late postoperative period using subvastus and medial parapatellar approach. A prospective randomized controlled study was conducted in a group of 169 patients (180 TKAs) with 2-year follow-up. Patients were divided into a study group (97 TKAs) with a subvastus approach and a control group (83 TKAs) with a parapatellar approach. Assessment of the results of both operating approaches was based on functional, clinical Knee Society Score, and pain (visual analog scale). Patients in the subvastus group achieved full active extension, better range of motion, and better Knee Society Score results at 12 days, 6 weeks, and 12 weeks earlier than patients in the medial parapatellar group. They also had less pain at 12 days. No statistically significant differences existed between assessed end points in both groups at 24- and 52-weeks, and 24-months postoperatively. The subvastus approach has given patients better early clinical results; however, at longer follow-up, both groups had similar outcomes. The potential benefits of the subvastus approach are: protection of the extensor mechanism from damage, less risk of damaging the blood supply to the patella, earlier clinical recovery, and less pain in the early postoperative period. The subvastus approach is an alternative to the standard medial parapatellar approach in TKA. It can be used with equally good results, especially taking into consideration positive clinical aspects in the early postoperative period.

Published: June 2011

The purposes of this article were identification (ie, verification and gradation) of anatomical risk factors that lead to anterior cruciate ligament (ACL) injury and determination of the probability of ACL injury among the population actively engaged in sports activities. We evaluated 66 patients divided into 2 groups: 33 patients in the examined group diagnosed with ACL lesion, and 33 patients in the control group diagnosed with patellofemoral pain. Patients were matched by age, sex, type of lesion, and whether the lesion was left or right sided. Measurements were carried out by radiography and magnetic resonance imaging. The study examined 32 anatomical factors. After identifying factors that lead to ACL injury, the following were determined: the coefficient of significance for each individual factor via the discriminant analysis and the canonical discriminant (ie, canonical correlation). Fifteen factors in men and 8 factors in women were differentiated as having influence on ACL injury. Based on these factors, it was determined whether the patients belonged to the examined or the control group with a success rate of 100% in men (100% sensitivity and specificity) and 91.7% in women (100% sensitivity and 83.3% specificity). The anatomy of the ACL prone to rupture and of the skeletal structures influencing it is significantly different from the anatomy of the ACL ligament resistant to injury. The probability of precise prognosis of ACL injury based on differentiated anatomical factors is 88.9% in men and 75.7% in women actively engaged in sports activities.
Preliminary Clinical and Radiographic Results of Large Ceramic Heads on Highly Cross-Linked Polyethylene

Published: June 2011

Data are limited regarding large ceramic femoral heads with highly cross-linked polyethylene. We hypothesized that large ceramic head articulation with highly cross-linked polyethylene is safe with a low wear rate, comparable to metal-on-highly cross-linked polyethylene.

The study group comprised 63 patients (72 hips) who had undergone total hip replacement (THR) with ceramic-on-highly cross-linked polyethylene between April 2006 and March 2007 with a minimum 2-year follow-up. Postoperative Western Ontario and Mc-Master Universities Arthritis Index (WOMAC) and Hospital for Special Surgery (HSS) scores were used for clinical assessment. Six-week and 2-year radiographs were analyzed by 2 independent observers using Roman 1.70 software. Twenty-six patients (29 hips) had 32-mm and 37 patients (43 hips) had 36-mm Biolox delta ceramic femoral heads (Ceramtec, Plochingen, Germany). Mean patient age was 60.9±8.9 years, and mean follow-up was 2.9±0.5 years. Mean postoperative WOMAC and HSS hip scores were 30.4 and 36.6, respectively. Mean wear at 1 and 2 years postoperatively was 0.06±0.28 and 0.006±0.12 mm/yr for all hips, respectively. Mean wear at 1 and 2 years postoperatively for the 32-mm femoral head was 0.063±0.278 and 0.007±0.126 mm/yr, respectively, and for the 36-mm femoral head was 0.057±0.292 and 0.006±0.118 mm/yr, respectively. No patient had any clinical complications, such as reoperation, infection, fractures, or radiographic evidence of osteolysis or loosening. The early results of THR with large ceramic heads demonstrate high safety and efficacy. Our data with 2-year follow-up show low wear rates, similar to published data for metal-on-highly cross-linked polyethylene.
The Characteristics of Patients with Type 1: Intraforaminal Vertebral Artery Anomalies?

Published: June 2011

In a previous study, intraforaminal anomalies were found to occur at a rate of 7.6%. This increases the risk of injury to this vessel if the surgeon is unaware of such abnormalities preoperatively. The aim of our retrospective study was to identify patient factors that may predict anomalous intraforaminal vertebral arteries. Patient records were obtained from a previous study. In that study, the records of each consecutive patient who underwent cervical spine magnetic resonance imaging (MRI) for axial neck pain, radiculopathy, or myelopathy between January 2007 and January 2008 were reviewed. The social and medical histories of each patient were evaluated with respect to the presence or absence of an aberrant vertebral artery. We reviewed the medical records of the 250 patients whose MRIs were reviewed in the previous study. Seven patients were excluded for incomplete records. Chi-square and Fisher’s exact tests were performed to compare the normal vertebral artery anatomy patients to the aberrant patients. The medical records of 19 patients with aberrant vertebral arteries and 224 patients with normal vertebral arteries were reviewed. The aberrant group was significantly older than the normal group (
P
=.00015). The only diagnostic condition that represented a statistically significant difference between the 2 groups was incidence of cancer. A relationship may exist between patient age, cancer, and medialization of the vertebral artery. The mechanism of this possible relationship is unclear. Although aberrant vertebral arteries are rare, a surgeon should have raised suspicion of this possibility in patients with a history of cancer.
Fatigue Load of Current Tibial Intramedullary Nail Designs: A Simulated Study
Authors: Wagner Mark , Liu Qi , Ellis Thomas J.
Published: June 2011

Comminuted tibial shaft fractures are traditionally treated with statically locked intramedullary nailing and protected weight bearing until fracture callous is evident. The purpose of this study was to demonstrate that a simulation of immediate full weight bearing following intramedullary nailing of these fractures does not result in implant failure.

A comminuted fracture model was created using 2 pieces of polyvinyl chloride (PVC) pipe. Ten-millimeter-diameter tibial nails (Synthes, Paoli, Pennsylvania; Styker, Mahwah, New Jersey; Zimmer, Warsaw, Indiana; Smith & Nephew, Memphis, Tennessee) were inserted within the PVC pipe and secured proximally and distally with 2 or 3 locking bolts. The constructs were cycled in axial compression for 500,000 cycles or until implant failure. The tests were conducted using a modified staircase method (200 N per step), and the fatigue strength was identified for each of the tibial nail designs. When 2 interlocking bolts were placed proximally and distally, the fatigue strength was between 900 and 1100 N for the Stryker nail, 1100 and 1300 N for the Zimmer nail, 1200 and 1400 N for the Synthes nail, and 1400 and 1600 N for the Smith & Nephew nail. Adding a third interlocking bolt proximally and distally to the Smith & Nephew nail increased the fatigue strength by 13% to between 1700 and 1900 N. In all cases, implant failures occurred through the proximal or distal interlocking bolts.

Biomechanical tests suggest that current tibial nail designs may permit immediate full weight bearing of comminuted tibial shaft fractures with minimal risk of implant failure. This may facilitate mobilization in the early postoperative period, especially in the multiply injured patient.

Published: June 2011

We conducted a prospective cross-sectional study to examine the correlation between facial asymmetry, shoulder imbalance, and adolescent idiopathic scoliosis. Sixty-nine adolescent idiopathic scoliosis patients and 29 healthy volunteers were enrolled in this study. All patients underwent whole-spine standing anteroposterior radiographs and frontal cephalograms. Patients were divided into mild, moderate, and severe groups depending on Cobb angle (10°–25°, 25°–40°, and >40°, respectively). Facial measurements included maxilla height difference, ramus length difference, and anterior nasal spine-menton angle. Shoulder measurements included coracoid height difference, clavicular angle, clavicle-rib intersection difference, and radiographic shoulder height.

The anterior nasal spine-menton angle in the severe group (>40°) was higher than in the other groups (
P
<.05), as was the clavicle-rib intersection difference (
P
<.05). In addition, the magnitude of the curve showed a possible correlation with the anterior nasal spine-menton angle and clavicle-rib intersection difference in scoliosis patients (
r
=0.433 and
r
=0.511, respectively). According to different curve patterns, the anterior nasal spine-menton angle and clavicle-rib intersection difference were significantly higher in the double thoracic group than in the other groups (
P
<.05). In the correlation analysis, the ramus length difference and anterior nasal spine-menton angle had a possible correlation with the coracoid height difference, clavicular angle, radiographic shoulder height, and clavicle-rib intersection difference (
P
<.05).
Open Repair and Arthroscopic Follow-Up of Severely Delaminated Femoral Head Cartilage Associated with Traumatic Obturator Fracture-Dislocation of the Hip
Authors: Lim Byung-Ho , Jang Sung-Won , Park Youn-Soo , Lim Seung-Jae
Published: June 2011

This article describes an unusual case of a young adult with traumatic obturator fracture-dislocation of the hip, involving a large femoral head fragment and severe delamination of articular cartilage. The dislocation was irreducible by closed reduction because of interposing soft tissues, including the rectus femoris and iliopsoas muscles, and torn joint capsules, and therefore, open reduction was performed using an anterolateral approach in the lateral decubitus position. The large femoral head fragment was released from the ligamentum teres and fixed to the dislocated femoral head with headless screws. The severely delaminated femoral head cartilage was repaired with suture anchors and absorbable sutures. The patient was kept nonweight bearing for 6 weeks postoperatively, and was then allowed to resume full weight bearing gradually. He returned to normal activities of daily living at 14 weeks. At 9 months postoperatively, arthroscopic examination showed complete healing of the fracture and cartilage lesions, and at 12-month follow-up, there was no clinical or radiographic evidence of arthritis or osteonecrosis. The patient had no pain or limp, and achieved an excellent result according to Epstein’s clinical evaluation criteria. To our knowledge, no previous report exists on the arthroscopic follow-up of a repaired femoral head cartilage in patients with obturator fracture-dislocation of the hip along with a large femoral head fragment and severe delamination of articular cartilage.
Posterior Spinal Fusion for Scoliosis in Ehlers-Danlos Syndrome, Kyphoscoliosis Type
Authors: Liu Yang , Gao Rui , Zhou Xuhui , Yuan Wen
Published: June 2011

The Ehlers-Danlos syndromes comprise a clinically and genetically heterogeneous group of heritable connective tissue disorders characterized by articular hypermobility, skin extensibility, and tissue fragility. Surgical treatment of scoliosis associated with Ehlers-Danlos syndrome poses a challenge to spine surgeons because of the high risk of major complications. There is a paucity of evidence in the literature on surgical treatment for scoliosis in the Ehlers-Danlos syndrome patient.

This article describes 3 adolescent patients diagnosed with Ehlers-Danlos syndrome, kyphoscoliosis type, which was treated by posterior spinal fusion only. After unsuccessful conservative treatment for at least 1 year, the patients underwent posterior spinal surgery for the correction of spinal deformity. A satisfactory correction in the spinal curve was achieved, with no obvious loss of correction during follow-up. No intra- or postoperative major complications were observed.

Our experience supports that a satisfactory correction of scoliosis can be achieved by posterior spinal fusion only in patients with Ehlers-Danlos syndrome, kyphoscoliosis type.
Femoral Stem Dislodgement During Bipolar Hemiarthroplasty Dislocation
Authors: Marcelino Gomes Luiz S. , do Carmo Wellington , de Souza Wender
Published: June 2011

Bipolar hemiarthroplasty remains a treatment option for displaced femoral neck fractures in elderly patients without pre-existing hip disease. Implant-related complications associated with this procedure include acetabular erosion, dislocation, disassembly of the modular components, polyethylene debris-induced osteolysis, metallosis from outer cup impingement, and femoral component loosening. This article presents a case of a patient in whom the polished collarless tapered femoral stem dislodged out of the cement mantle during traumatic bipolar hemiarthroplasty dislocation, 28 days after the index procedure. This complication, associated with bipolar hemiarthroplasty dislocation, was adequately managed by driving the stem back to the original cement mantle, followed by reduction of bipolar component dislocation and placing bone cement over the shoulder of the femoral stem to prevent a new dislodgement episode. Although rare, dislodgement of cemented polished collarless tapered stems from the cement mantle has been recently reported either during dislocation or, more frequently, as a complication of reduction of a dislocated total hip arthroplasty. However, its occurrence in association with bipolar hemiarthroplasty dislocation was not found to have been reported in the literature. The occurrence of femoral stem dislodgement during bipolar hemiarthroplasty dislocation should be considered as a possible complication of such a procedure and may be prevented by routinely placing bone cement over the shoulder of the femoral implant.
Atypical Tibial Tuberosity Fracture in an Adolescent
Authors: Jalgaonkar Azal A. , Dachepalli Sunil , Al-Wattar Zaid , Rao Sudhir , Kochhar Tony
Published: June 2011

Avulsion fractures of the tibial tuberosity are typically sustained by adolescent males during sporting activities. Tibial tuberosity avulsions with simultaneous proximal tibial epiphyseal fractures are rare injuries. We present an unusual case of Ogden type IIIA avulsion fracture of tibial tuberosity with a Salter Harris type IV posterior fracture of proximal tibial epiphysis in a 13-year-old boy. We believe that the patient sustained the tibial tuberosity avulsion during the take-off phase of a jump while playing basketball due to sudden violent contraction of the quadriceps as the knee was extending. This was then followed by the posterior Salter Harris type IV fracture of proximal tibial physis as he landed on his leg with enormous forces passing through the knee. Although standard radiographs were helpful in diagnosing the complex fracture pattern, precise configuration was only established by computed tomography (CT) scan. The scan also excluded well-recognized concomitant injuries including ligament and meniscal injuries. Unlike other reported cases, our patient did not have compartment syndrome. Anatomic reduction and stabilization with a partially threaded transepiphyseal cannulated screw and a metaphyseal screw followed by early mobilization ensured an excellent recovery by the patient.

Our case highlights the importance of vigilance and a high index of suspicion for coexisting fractures or soft tissue injuries when treating avulsion fractures of tibial tuberosity. A CT scan is justified in such patients to recognize complex fracture configurations, and surgical treatment should be directed appropriately to both the fractures followed by early rehabilitation. Patients with such injuries warrant close monitoring for compartment syndrome during the perioperative period.
Repair of Flexor Carpi Radialis Tendon Laceration at the Wrist in a Professional Ice Hockey Player
Authors: Hepper Clifford T. , Boyer Martin
Published: June 2011

The flexor carpi radialis is a wrist flexor and radial deviator with half the relative strength of flexor carpi ulnaris. In the majority of patients, the flexor carpi radialis tendon is expendable and is routinely used for various reconstructive procedures about the hand and wrist. Isolated flexor carpi radialis lacerations at the wrist are rare. Flexor carpi radialis tendon ruptures, which have been reported in association with distal radius fractures, longstanding osteoarthritis, and percutaneous treatment of scaphoid fractures, are usually treated non-operatively. We report a case of a traumatic laceration of the flexor carpi radialis tendon at the wrist in a professional ice hockey player. Surgical repair and rehabilitation using established principles for intrasynovial flexor tendon repair allowed return to sport at the professional level in 2 months.

Tension-free core suture repair was performed with a modified-Kessler, 4-strand repair using a double-stranded 4-0 Supramid suture. A running epitendinous suture was then placed around the circumference of the tendon with 6-0 Prolene. Immobilization of the wrist in 20° of flexion was maintained for 2 weeks. Full active and passive digital motion was allowed immediately postoperatively and continued throughout the rehabilitation. Therapy was initiated at 2 weeks postoperatively with full passive wrist flexion and passive wrist extension to a dorsal block of 20°. At 4 weeks postoperatively, a dorsal splint was fabricated to keep the wrist in neutral. At this time, active extension to a dorsal block of zero and full passive flexion was allowed. Active wrist flexion without resistance was begun at 6 weeks, and full strengthening was allowed at 8 weeks postoperatively. The patient returned to sport at the professional level shortly thereafter. At latest follow-up, the patient has been able to fully participate in professional ice hockey without pain or functional limitation.
Chronic Exertional Compartment Syndrome with Medial Tibial Stress Syndrome in Twins
Authors: Banerjee Purnajyoti , Mclean Christopher
Published: June 2011

Chronic exertional compartment syndrome and medial tibial stress syndrome are uncommon conditions that affect long-distance runners or players involved in team sports that require extensive running. We report 2 cases of bilateral chronic exertional compartment syndrome, with medial tibial stress syndrome in identical twins diagnosed with the use of a Kodiag monitor (B. Braun Medical, Sheffield, United Kingdom) fulfilling the modified diagnostic criteria for chronic exertional compartment syndrome as described by Pedowitz et al, which includes: (1) pre-exercise compartment pressure level >15 mm Hg; (2) 1 minute post-exercise pressure >30 mm Hg; and (3) 5 minutes post-exercise pressure >20 mm Hg in the presence of clinical features. Both patients were treated with bilateral anterior fasciotomies through minimal incision and deep posterior fasciotomies with tibial periosteal stripping performed through longer anteromedial incisions under direct vision followed by intensive physiotherapy resulting in complete symptomatic recovery. The etiology of chronic exertional compartment syndrome is not fully understood, but it is postulated abnormal increases in intramuscular pressure during exercise impair local perfusion, causing ischemic muscle pain. No familial predisposition has been reported to date. However, some authors have found that no significant difference exists in the relative perfusion, in patients, diagnosed with chronic exertional compartment syndrome. Magnetic resonance images of affected compartments have indicated that the pain is not due to ischemia, but rather from a disproportionate oxygen supply versus demand. We believe this is the first report of chronic exertional compartment syndrome with medial tibial stress syndrome in twins, raising the question of whether there is a genetic predisposition to the causation of these conditions.

One of the most important and complex diseases of modern society is metabolic syndrome. This syndrome has not been completely understood, and therefore an effective treatment is not available yet. We propose a possible stem cell mechanism involved in the development of metabolic syndrome. This way of thinking lets us consider also other significant pathologies that could have similar etiopathogenic pathways, like lipodystrophic syndromes, progeria, and aging. All these clinical situations could be the consequence of a progressive and persistent stem cell exhaustion syndrome (SCES). The main outcome of this SCES would be an irreversible loss of the effective regenerative mesenchymal stem cells (MSCs) pools. In this way, the normal repairing capacities of the organism could become inefficient. Our point of view could open the possibility for a new strategy of treatment in metabolic syndrome, lipodystrophic syndromes, progeria, and even aging: stem cell therapies.
Electroencephalography as a Tool for Assessment of Brain Ischemic Alterations after Open Heart Operations
Authors: Golukhova Elena Z. , Polunina Anna G. , Lefterova Natalia P. , Begachev Alexey V.
Published: June 2011

Cardiac surgery is commonly associated with brain ischemia. Few studies addressed brain electric activity changes after on-pump operations. Eyes closed EEG was performed in 22 patients (mean age: ) before and two weeks after valve replacement. Spouses of patients were invited to participate as controls. Generalized increase of beta power most prominent in beta-1 band was an unambiguous pathological sign of postoperative cortex dysfunction, probably, manifesting due to gamma-activity slowing (“beta buzz” symptom). Generalized postoperative increase of delta-1 mean frequency along with increase of slow-wave activity in right posterior region may be hypothesized to be a consequence of intraoperative ischemia as well. At the same time, significant changes of alpha activity were observed in both patient and control groups, and, therefore, may be considered as physiological. Unexpectedly, controls showed prominent increase of electric activity in left temporal region whereas patients were deficient in left hemisphere activity in comparison with controls at postoperative followup. Further research is needed in order to determine the true neurological meaning of the EEG findings after on-pump operations.

Uniform decay rates of coupled anisotropic elastodynamic/Maxwell equations with nonlinear damping
Authors: da Luz Cleverson Roberto , Perla Menzala Gustavo Alberto
Published: June 2011

This work is devoted to study the asymptotic behavior of the total energy associated with a coupled system of anisotropic hyperbolic models: the elastodynamic equations and Maxwell's system in the exterior of a bounded body in

\mathbb{R}^3

. Our main result says that in the presence of nonlinear damping, a unique solution of small initial data exists globally in time and the total energy as well as higher order energies decay at a uniform rate as

t \rightarrow + \infty

Shorelines: In Memory of Édouard Glissant
Authors: Drabinski John E.
Published: June 2011

Édouard Glissant passed away on 4 February 2011 at the age of 82. A few words of memory. As a person and thinker, Glissant lived through, then reflected with meditative patience and profundity upon some of the most critical years in the black Atlantic: the aesthetics and politics of anti-colonial struggle, the civil rights movement in the United States, postcolonial cultural anxiety and explosion, the vicissitudes of an emerging cultural globalism, and all of the accompanying intellectual movements from surrealism to negritude to existentialism to those varieties of high modernism and postmodernism for which Glissant himself is such a generative, founding resource. His life bears witness to those years, events, and movements with a poet’s word and a philosopher’s eye. And so Glissant, like all important thinkers, leaves for us an enormous gift – in his case, a new, enigmatic vocabulary of and for the Americas.
To Dream of Fanon: Reconstructing a Method for Thought by a Revolutionary Intellectual
Authors: Prabhu Anjali
Published: June 2011

The half-century, which is the time that has elapsed since the publication of Wretched of the Earth, seems such a short period when one imagines its author in all his intellectual magnificence, his anguish, and the many details we all know of his short-lived reality. Dare one say, after the concept has long been declared “dead” that we imagine him as having been a live “author”? As I write this, the idea of various notable intellectuals and revolutionary movements could come to mind in order for them to serve as interesting comparisons as we discuss and remember Fanon, his analyses of the colonial aftermath, and his many predictions, both explicit and implicit. However, the “death” of the author is, in fact, as Barthes’ polemical essay showed, a premise that empowers the text in its full potentiality well beyond the deism by which the identity of the author becomes the authority. Here, the liberation of the text joins up the enunciation with its “content” so to speak, or in Barthes’ words, reveals how Fanon “made of his very life a work for which his book was a model.” It is from this idea that I wish to see Fanon as incomparable. The reason to do so does not stem from some esoteric form of admiration, but rather a conviction that Fanon’s narration itself is both indicative and exemplary of a process of thinking that, for me, remains unparalleled in theorizing the role of the intellectual. Such a conviction requires us to read beyond the content of Wretched and be “reborn” in the Barthesian sense as readers. In essence, it is to simply follow the way Fanon himself allows us to actually trace how he dreams of “the native” or “the people” and thus accomplishes an affective leap, arguably, more completely than any other intellectual. This reading is, thus, an invitation to dream – even momentarily – of Fanon.
Further Questions: A Way Out of the Present Philosophical Situation (via Foucault)
Authors: Lawlor Leonard
Published: June 2011

Let us begin by assembling some signs of the present philosophical situation. On the one hand, the most important living French philosopher, Alain Badiou, calls for a “return to Plato,” despite the movement of anti-Platonism that dominated French and German thought in the 20th century. On the other hand, the present moment sees a resurgence of naturalism in philosophy in general (including and especially Anglophone analytic philosophy), despite the criticisms of naturalism that have appeared throughout the 20th century. Phenomenology seems to be at the center of both of these movements. On the one hand, it is the idea of a mathematized ontology that requires the return to Plato, a mathematized ontology constructed without a reflection on its transcendental grounds. On the other, the resurgence of naturalism is so strong that a book could be imagined and published with the bastard name of Naturalizing Phenomenology, as if the transcendental moment of phenomenology did not transform the very meaning of nature. These signs seem to indicate that we have entered into a phase of regression or even decline in philosophical thinking. If this interpretation of the signs is correct, if we have indeed entered into a phase of regression -- a twofold regression toward Platonism and toward naturalism -- we must ask the following question: is it possible for us to define something like a project or even a research agenda that would allow us to define a way of thinking that might lead us out of the present situation, a situation, it must be said, that seems dire for philosophy in general? If we can determine such a research agenda, perhaps we can also begin to understand what the tradition of “continental philosophy” has stood for.
Totality and Infinity, Alterity, and Relation: From Levinas to Glissant
Authors: Cailler Bernadette
Published: June 2011

Totality and Infinity, the title of a well-known work by Emmanuel Levinas, takes up a word which readers of Poetic Intention and of many other texts of Édouard Glissant’s will easily recognize: a term sometimes used in a sense that is clearly positive, sometimes in a sense that is not quite as positive, such as when, for instance, he compares “totalizing Reason” to the “Montaigne’s tolerant relativism.” In his final collection of essays, Traité du tout-monde, Poétique IV, Glissant attempts one more time to clarify the sense in which the reader will have to understand his use of the word “totality,” thinking, and rightfully so, that this word might lead to some confusion: “To write is to say the world. The world as totality, which is so dangerously close to the totalitarian.” Of course, here, it will be necessary to try to ascertain whether or not Levinas’s totality and Glissant’s can peacefully coexist, or, rather, whether this word might, in Glissant, have opposite meanings. Where the second word is concerned, “infinity,” any reader of Glissant will know that he locates its source in those societies he calls atavistic, which are grounded in foundational texts that are the bearers of stories of filiation, of legitimacy, societies whose arrogance and whose errors the author never ceases to decry and whose decomposition, in the very times in which we live, he never ceases to announce (even as Glissant recognizes that there was a time when atavistic cultures undoubtedly must have experienced their own period of creolization, and that, conversely, composite cultures undoubtedly often tend to become atavistic). On this level, “totality” and “infinity,” for him, seem to belong to the same world. Thus, and still in Traité du tout-monde , he proposes that "Hebraism, Christianity, Islam are grounded in the same spirituality of the One and to the same belief in a revealed Truth… The thought of the One that has done so much to magnify, as well as to denature. How can one consent to this thought, which transfigures while neither offending nor de-routing the Diverse?" Moreover, it would be interesting, I think, to know how Levinas might react to these words of Glissant’s: “Totality is not that which has often been called the universal. It is the finite and realized quantity of the infinite detail of the real.” This word, “infinite,” is decidedly dangerous: what is an “infinite detail?” Does this word, “infinite,” not always lead to the unknown, to the non-totalizable, to what Levinas would call an “enigma,” to what Glissant would call an “opacity?”

Subsidence of the Corail Femoral Component in the Elderly. A Retrospective Radiological Review
Authors: Faisal Mohammad , Thomas Gethin , Young Stephen K.
Published: June 2011

206 patients age 70 years or older who underwent uncemented total hip arthroplasty (THA) using the Corail stem were studied. Radiographs taken post operatively and at one year were measured for subsidence of the stem. 13 patients had subsidence of the femoral stem of more than 2mm. 5 of these were associated with fractures (mean age 78.06 years - average subsidence 14.52mm), while 8 did not have associated fractures (mean age 77.43 years - average subsidence 4.99mm). These 13 patients were then followed up for an average of 25 months (with fractures) and 26.88 months (without fractures). Radiographs were taken and measured for further subsidence using a VIDAR scanner. There was no evidence of further subsidence in any of the 13 patients, and all the stems had stabilised at one year with good evidence of osteointegration. None of the patients required revision. Uncemented THA using the Corail stem can be employed in this age group and poor bone quality is not a contraindication.
