Place des processus de déconstruction dans l'appropriation subjective à l'adolescence
Authors: Matot Jean-Paul 
Published: June 2011

Résumé Dans les perspectives psychanalytiques actuelles, un des axes centraux du développement à l’adolescence est envisagé comme un processus d’appropriation subjective, lequel ne peut cependant se concevoir que comme temps second d’une déconstruction préalable. Cette déconstruction est souvent ressentie par les adultes, et secondairement par les adolescents eux-mêmes, comme violente, alors que cette violence, qui est profondément structurante, constitue avant tout une condition de la croissance psychique et d’un développement personnel authentique. Elle répond en effet à la violence inhérente au contrat narcissique primaire. La distinction entre déconstruction et destructivité constitue une condition d’une appréciation des dynamiques en jeu à l’adolescence qui préserve au mieux leur potentiel de vitalité et de créativité. De ce point de vue, il est important sur le plan de la théorie psychanalytique de lever la confusion introduite par Freud à partir de 1920 entre les processus de liaison-déliaison, inhérents au développement et à la pensée, et le registre de la destructivité. Les mouvements de déconstruction à l’adolescence concernent le corps, les liens aux parents et les modalités des rapports aux structures sociales. Ils peuvent être entravés par des limitations liées aux capacités propres de l’adolescent ainsi que par différentes formes d’interdits. Ils peuvent aussi se dégrader dans le sens de la destructivité. À cet égard, la différenciation entre des mouvements de déconstruction qui recherchent la transformation des liens objectaux, et ceux qui visent leur abolition, est importante sur le plan clinique et thérapeutique. Cette différence est illustrée par la comparaison entre deux films traitant de la révolte adolescente, Rebel without a cause et Into the wild .
Échelle d'évaluation du risque de récidive (ecarr). Étude de validation prospective d'une répétition d'accident

Published: June 2011

Résumé L’accident est, de loin, la principale cause de morbidité et de mortalité dans la tranche d’âge des 15-24 ans. Concernant la mortalité, les accidents de circulation en sont la principale cause en France. Ce pays est d’ailleurs en Europe celui qui présente un des taux les plus élevés. Parmi ces jeunes accidentés, un nombre conséquent (30 à 50 %) aura une récidive dans l’année suivant le premier accident. Ainsi, au sein des services d’urgences, de nombreux adolescents admis suite à un accident s’inscrivent manifestement dans une logique de répétition. L’objectif du présent travail est de proposer une échelle d’évaluation permettant de repérer parmi les divers adolescents accidentés ceux qui sont principalement à risque de récidive. La présente étude a porté sur une population de 350 adolescents venant consulter aux urgences à la suite d’un accident quelle qu’en soit la nature et quelle qu’en soit la gravité. L’Échelle d’évaluation des circonstances de l’accident et du risque de récidive ( ecarr ), échelle de douze items qui a été spécialement conçue à cette intention, a été proposée à tous ces adolescents lors de l’accident initial (accident index). Sur cette population de 350 jeunes, presque la moitié (46 %) aura dans les deux ans qui suivent une répétition d’accident, laquelle survient souvent dans les quelques mois suivant l’accident initial. Le score ecarr était pour tous les adolescents, à l’inclusion, de 4,3. En revanche, ce score n’était que de 3,9 chez les adolescents indemnes de récidive et était d’autant plus élevé que la récidive était précoce et qu’il s’agissait d’accidents de circulation (score ecarr pour les adolescents ayant des récidives d’accident de circulation : 6,2). Ainsi, l’échelle ecarr permet de repérer les adolescents à risque de récidive précoce, accident pour lequel existe manifestement un lien entre l’événement initial et sa répétition. Un score supérieur ou égal à 5 semble ainsi prédicteur d’une répétition précoce d’accident, résultat particulièrement probant dans le cas des accidents de circulation. À partir de ces constatations, il serait hautement souhaitable d’envisager pour tous les adolescents présentant un score égal ou supérieur à 5 à l’échelle ecarr un suivi régulier afin, si possible, de réduire la fréquence de ces récidives.
Treatment of Acute Unstable Distal Clavicle Fractures with Single Coracoclavicular Suture Fixation

Published: June 2011

Distal clavicular fractures are less common than fractures involving the middle third of the clavicle. For Neer type IIb distal clavicular unstable fractures associated with disruption of the coracoclavicular ligament, surgical treatment is indicated because of the high risk of nonunion. Various surgical methods can be found in the literature, but no gold standard has been established. We treated 29 consecutive adult patients with unstable distal clavicular fracture with single coracoclavicular suture fixation by using single Mersilene tape (Ethicon, Somerville, New Jersey) and without repair of the torn coracoclavicular ligament or hardware implantation.
Twenty-eight patients were followed for at least 46 months (mean, 57.3 months). All fractures healed without further treatment, with a mean time to union of 14.3 weeks. There was no major morbidity, but 2 minor complications occurred. One patient experienced a frozen shoulder on the treated side postoperatively. After adequate rehabilitation, the symptom resolved without any complications at final follow-up. Another patient reported uncomfortable skin tenting due to subcutaneous protrusion of the suture node of the Mersilene tape. After simple subcutaneous surgical removal of the node under local anesthesia, the discomfort resolved. Mean University of California Los Angeles shoulder rating score was 34 (range, 29–35). Twenty patients had excellent results and 8 had good results. All patients resumed their previous levels of activity.
Chemoprophylaxis Without Intra-Articular Wound Drainage Can Replace Autotransfusion in Primary TKA
Authors: Hourlier Hervé , Fennema Peter 
Published: June 2011

We compared outcomes in 2 groups undergoing total knee arthroplasty (TKA) with different blood-saving strategies (ie, chemoprophylaxis vs reinfusion). We hypothesized that chemoprophylaxis would lead to reduced blood loss and fewer transfusions, with no increase in associated complications. Group A was a prospective series of 91 consecutive cemented TKAs undertaken with chemoprophylaxis to reduce bleeding and blood allogeneic exposure. Group B consisted of 44 historical TKAs undertaken with postoperative reinfusion. With the exception of mean patient age (group A, 74.3 years; group B, 70.9 years;
P
=.006), there were no statistically significant differences between the 2 study groups.

Mean total blood loss throughout the 7-day perioperative period was 1490 mL in group A and 1828 mL in group B. The rate of blood transfusion in group A was almost zero. In group B, 41 of 44 patients were administered blood intravenously. Despite the absence of autotransfusion, postoperative hemoglobin levels were significantly higher in group A than in group B. No major bleeding complications emerged in the immediate postoperative period in either group.
Chemoprophylaxis proved superior to reinfusion at decreasing blood transfusion requirements in the routine daily setting of unilateral cemented primary TKA.
Palmar Locking Plates for Corrective Osteotomy of Latent Malunion of Dorsally Tilted Distal Radial Fractures Without Structural Bone Grafting
Authors: Tarng Yih-Wen , Yang Shan-Wei , Hsu Chien-Jen 
Published: June 2011

The purpose of this retrospective study was to investigate the clinical and radiological outcomes following corrective osteotomy for nascent malunion of distal radial fractures with dorsal tilt using palmar-locking plates without using autologous structural bone grafting for dorsal cortex support. The fractures were dorsally angulated distal radial fractures (AO types A2, A3, and C1) with neglected or delayed treatment for 5 to 8 weeks. Fractures were repaired using 2.4-mm palmar locking plates. Dorsal cortical defects at the osteotomy sites were filled with incipient healing callus. Radiographs were obtained before correction and at 2 and 6 weeks and 3, 4.5, 6, and 12 months postoperatively. Palmar tilt, radial inclination, and ulnar variance were measured. There were no cases of loss reduction, implant failure, or delayed fracture union without structural bone graft and casting. Clinical assessments included active range of motion of the wrist and function based on the Mayo Wrist Score. Even with wrist immobilization for >1 month preoperatively, all patients had excellent Mayo Wrist Scores at 4.5 months due to early postoperative rehabilitation. No further changes were apparent between 4.5- and 12-month follow-up.
The palmar locking plates provided sufficient stability for corrective osteotomy within 8 weeks of injury without the need for structural bone grafting. Furthermore, casting immobilization was also unnecessary, and a good wrist range of motion was restored early after rehabilitation.
Proximal Humerus Shaft Fracture After Pectoralis Major Tendon Rupture Repair
Authors: Silverstein Jeff A. , Goldberg Ben , Wolin Preston 
Published: June 2011

Surgical repair of a complete pectoralis major tendon rupture at the humeral insertion has superior results compared to nonoperative treatment. To our knowledge, a proximal humerus shaft fracture occurring at the site of the bone trough and cortical drill holes after a pectoralis major tendon rupture repair has not been reported in the literature.
A 45-year-old man sustained an acute left pectoralis major tendon rupture at the humeral insertion while performing a bench press maneuver. He underwent acute surgical repair. Approximately 8 weeks postoperatively, the patient fell from a standing height and sustained a proximal humerus shaft fracture through the repair site at the bone trough. Three days after the fracture, the patient underwent open reduction and internal fixation of the proximal humerus shaft fracture and exploration of the pectoralis major tendon repair. The fracture was found to be at the level of the repair site, and the pectoralis major tendon was completely intact to the distal fragment. The fracture healed uneventfully, and the patient regained full motion and strength of his extremity with no limitations.
Any type of surgical fixation that creates a hole in the humerus or decreases the cross-sectional area such as a bone trough creates a stress riser. Patients undergoing pectoralis tendon repair that involves violating the humerus with a bone trough or hole have a slight risk of postoperative humerus fracture, especially if sustaining an early traumatic event such as a fall.
Symptomatic Spinal Epidural Lipomatosis with Severe Obesity at a Young Age

Published: June 2011

Symptomatic spinal epidural lipomatosis is a rare disorder characterized by overgrowth of fat in the extradural space. Most patients have an underlying endocrine disorder, such as Cushing’s syndrome, or have taken exogenous steroids chronically. Although less common, obesity alone is thought to be a cause of spinal epidural lipomatosis, representing <25% of reported cases. Patients rarely become symptomatic before middle age without chronic exogenous steroid use. The usual clinical manifestations are similar to degenerative lumbar stenosis with neurogenic claudication, resulting in decreased walking and standing endurance with variable neurological deficits.
This article describes 2 unique cases of spinal epidural lipomatosis, both in young patients with underlying morbid obesity who presented with acute progressive leg weakness and urinary retention. The patients had no underlying endocrinopathy, nor any history of exogenous steroid use. They underwent emergency laminectomy and removal of epidural fat, and histopathological examination confirmed the diagnosis of epidural lipomatosis. Postoperatively, the patients demonstrated significant improvement.
We conducted a review of the available English literature and compared the age distribution in each group. Based on our review, our 2 patients are considerably younger than those in past reports, especially in the patient group to which the steroid was not administered. In addition, few cases exist of spinal epidural lipomatosis with acute sphincter dysfunction and paraparesis. Our cases suggest that morbid obesity can lead to juvenile spinal epidural lipomatosis with acute neurological changes.

Treatment of soft tissue defects with exposed bones and joints, resulting from trauma, infection, and surgical complications, represents a major challenge. The introduction of negative pressure wound therapy has changed many wound management practices. Negative pressure wound therapy has recently been used in the orthopedic field for management of traumatic or open wounds with exposed bone, nerve, tendon, and orthopedic implants. This article describes a case of a patient with a large soft tissue defect and exposed knee joint, in which negative pressure wound therapy markedly improved wound healing. A 50-year-old man presented with an ulceration of his left knee with exposed joint, caused by severe wound infections after open reduction and internal fixation of a patellar fracture. After 20 days of negative pressure wound therapy, a granulated wound bed covered the exposed bones and joint.
To our knowledge, this is the first report of negative pressure wound therapy used in a patient with a large soft tissue defect with exposed knee joint. Despite the chronic wound secondary to infection, healing was achieved through the use of the negative pressure wound therapy, thus promoting granulation tissue formation and closing the joint. We suggest negative pressure wound therapy as an alternative option for patients with lower limb wounds containing exposed bones and joints when free flap transfer is contraindicated. Our result added to the growing evidence that negative pressure wound therapy is a useful adjunctive treatment for open wounds around the knee joint.

Authors: Jaimes Martha , Xacur-García Fiona , Alvarez-Melloni Diana , Graue-Hernández Enrique O. , Ramirez-Luquín Tito , Navas Alejandro 
Published: June 2011

PURPOSE:
To report the clinical characteristics and surgical outcomes of patients with nonprogressive keratoconus treated with in-the-bag toric intraocular lens (IOL) implantation.

METHODS:
A retrospective review was conducted of the medical records of patients diagnosed with keratoconus treated with refractive lens exchange (RLE) and in-the-bag toric IOL implantation (models T3 to T9, AcrySof SN60TT; Alcon Laboratories Inc). Age, pre- and postoperative uncorrected (UDVA) and corrected distance visual acuity (CDVA), objective and subjective refraction, spherical equivalent refraction, total keratometric power, total astigmatism, axis, and toric IOL model and power were analyzed. All cases had topographic and/or refractive stability for at least 1 year prior to undergoing IOL implantation.

RESULTS:

Nineteen eyes of 13 patients (mean age 48.15±6.6 years), including 12 patients with a topographic diagnosis of keratoconus and 1 with pellucid marginal degeneration, were evaluated. Mean follow-up after RLE was 7.89±6.61 months. Mean preoperative sphere was −5.25±6.40 diopters (D), and mean postoperative sphere was 0.22±1.01 D (
P
<.001). Mean preoperative cylinder was 3.95±1.30 D, which decreased to 1.36±1.17 D postoperatively (
P
<.001). Mean pre- and postoperative spherical equivalent refractions were −7.10±6.41 D and −0.46±1.12 D, respectively (
P
<.001). Preoperative mean UDVA was 1.35±0.36 D (20/447 Snellen) and postoperative mean UDVA was 0.29±0.23 D (20/39 Snellen) (
P
<.001).

CONCLUSIONS:
Toric IOL implantation may be an effective therapeutic option in the optical rehabilitation of patients with stable and nonprogressive keratoconus.
Toute décolonisation est une réussite: Les damnés de la terre and the African Spring
Authors: Alessandrini Anthony C. 
Published: June 2011

I’m certainly not alone in noting that the year 2011 brings, for those of us who are students of the work of Frantz Fanon, two different anniversaries. This year marks the fiftieth anniversary of the publication of Les damnés de la terre, Fanon’s final book and, for many, his most lasting achievement. But it also marks the fiftieth anniversary of Fanon’s death: he died, tragically young, on December 6, 1961, not long after the book’s publication. It is no exaggeration to say that Les damnés de la terre was composed by Fanon from his deathbed, and that he was well aware that he was racing death as he rushed to complete the manuscript, as his publisher François Maspero remarked, “in pitiful haste.” Fanon had managed to complete it by July, although, as he told a friend, “I should have liked to have written something more.” As David Macey notes in his indispensable biography, “Fanon did see copies of his last book, but for its first readers, Les damnés de la terre was a posthumous work.” The book and Fanon’s death thus come to us bound inextricably together, fifty years later. So it would seem that we have an anniversary to celebrate (and in doing so, we would thus be celebrating the continuing relevance of a classic work, as this special issue intends us to do), but also a death to mourn. If I proceed to make a suggestion that will seem at first to be the height of perversity, let me preface it by saying that this suggestion is occasioned by what I believe to be Fanon’s greatest legacy, a legacy of unsparing intellectual and political commitment. For I want to begin by suggesting that this year brings us the mournful fact that fifty years on, Les damnés de la terre remains, in many ways, as relevant to our contemporary world as it was in 1961; but conversely, the anniversary of Fanon’s death offers us a cause for celebration.
Corps à corps: Frantz Fanon's Erotics of National Liberation
Authors: Renault Matthieu 
Published: June 2011

In this short essay, I will endeavour to show that Frantz Fanon’s well-known conception of struggles for national liberation is intimately linked to an erotics of liberation. This one takes its roots in a shift, or better a reversal, of theories of racism. As Etienne Balibar argues, “racism,” as a category, appears at mid 19th century, especially under the aegis of the UNESCO, as a break with the conceptions of “race,” considered to be a pure “myth” or “prejudice.” A better example of such an epistemological rupture is probably Sartre’s Antisemite and Jew and its motto: “the Jew is a man whom other men consider a Jew…it is the anti-Semite who makes the Jew.” In other words, race is nothing but the product of racism. The biological arguments that underlie the theories of race are “false” arguments inasmuch as they depend on ideological and/or psychological premises.

Published: June 2011

La Stevia rebaudiana B. es la única planta que se conoce que produce edulcorante natural no calórico denominado steviósido, el cual es 300 veces más dulce que el azúcar de caña. Este estudio fue realizado con el propósito de establecer un protocolo de producción in vitro del cultivo a partir de segmentos nodales, así como establecer un costo por planta propagada. En la etapa de establecimiento se evaluó la consistencia del medio (sólido o líquido), la concentración de macroelementos Murashige y Skoog (MS) (50 ó 100%), el tipo de citocinina (kinetina o 6- bencilaminopurina) y la cantidad de cada citocinina (0, 2, 4, ó 6 μM/L) en un medio basal de MS. El mayor tamaño de brotes resultó en el medio líquido MS con 50% de macroelementos y 6 μM de bencilaminopurina (BAP). En la etapa de multiplicación este tratamiento fue sometido a tres cantidades de kinetina (2, 4 ó 6 μM) para inducir más brotes y crecimiento. Para esta etapa, el mejor resultado se obtuvo en el medio con 6 μM de kinetina. Las pruebas para el enraizamiento in vitro de las vitroplantas se realizaron en un medio basal de MS con tres tipos de auxina: ácido indoleacético (AIA), ácido indolebutírico (AIB) o ácido naftaleneacético (ANA) y cinco concentraciones para cada tipo de auxina; la mayor cantidad y la mejor calidad de raíces se obtuvo utilizando 0.5 mg/L de ANA a los 15 días después de su inducción. Las plantas más altas y el mayor número de plantas aclimatadas se obtuvieron usando microtúneles en bolsa plásticas y con un substrato compuesto por Pro-Mix ‘BX’:arena (1:1). Bajo condiciones de laboratorio, a partir de un explante que se establezca en la Etapa I o de establecimiento se obtiene aproximadamente 8,000 vitroplantas listas para aclimatación, empleando una tasa de multiplicación de 6, a un costo promedio de $ 1.69 por vitroplanta aclimatada.

Efecto del pH del Agua en la Efectividad de los Herbicidas Glifosato, Fluazifop-p-butil y Bentazon
Authors: Gómez Vargas José María , Pitty Abelino , Miselem José María 
Published: June 2011

Se realizaron tres experimentos para evaluar el efecto del pH del agua de aplicación sobre la eficacia de los herbicidas posemergentes Glifosato (sal monoamónica en la formulación Roundup Max® 680 SG), Fluazifop-p-butil ester (Fusilade 12.5 EC®) y Bentazon (sal sódica en la formulación Basagran 48 EC®). Cada herbicida fue un experimento y con cada herbicida se usó un pH de 8.50, 6.50 ó 4.50 del agua de aplicación, cada pH fue usado con la dosis del herbicida recomendada (100%) y 75% de la dosis recomendada por el fabricante para el control de la maleza evaluada, además, hubo un testigo que no fue aplicado con herbicida ni se usó en el análisis estadístico. La variable medida fue el porcentaje de control de malezas; para Glifosato y Fluazifop-p-butil la maleza aplicada fue la estrella africana (Cynodon nlemfuensis Vanderyst), para Bentazon fue la flor amarilla (Melampodium divaricatum [Rich.] DC). Con Glifosato se utilizaron 2500 y 1870 g a.e./ha; no se encontró diferencia estadística entre los tres pH del agua (α>0.05). Al añadir Roundup Max® 680 SG al agua, el pH baja a niveles entre 4.03 y 4.13, independientemente de si el pH inicial del agua era 8.50, 6.50 ó 4.50, indicación que esta formulación de Glifosato tiene un regulador de pH. Con Fluazifop-p-butil se utilizaron 210 y 160 g i.a./ha y se encontró una reducción en el control de la maleza al usar agua con pH 8.5 con la cantidad de herbicida reducida a 75% (160 g i.a./ha) de la recomendada, con respecto al resto de los tratamientos; pero al usar la dosis recomendada no hubo diferencia del control de malezas causada por el pH del agua utilizada. Con Bentazon se encontraron diferencias en el control de Melampodium divaricatum; las aplicaciones con pH del agua de 4.50 y 8.50 y usando la cantidad de herbicida reducida a 75% (840 g i.a./ha) de la cantidad recomendada por el fabricante, tuvieron un control inferior al resto de los tratamientos, pero no hubo reducción en el control bajo ningún pH evaluado al usar la dosis recomendada. El pH del agua no influyó en el control de malezas, con ninguno de los herbicidas, al usar la dosis recomendada por los fabricantes.Palabras clave: Basagran 48 EC®; Fusilade 12.5 EC®; mezcla de aplicación; Roundup Max® 68 SG.
