Revue de la littérature 2013--les neuropathies inflammatoires [2013: what's new in inflammatory neuropathies].

Several high-quality publications were published in 2013 and some major trials studies were started. In Guillain-Barré syndrome, events included the launch of IGOS and a better understanding of diagnostic limits, the effect of influenza vaccination, and better care, but uncertainty remains about analgesics. A new mouse model was also described. In chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), diagnostic pitfalls can be recalled. Our knowledge of underlying pathophysiological processes has improved, and the value of monitoring with function and deficit scores has been demonstrated. IVIG can sometimes be effective longer than expected, but CIDP remains sensitive to corticosteroids, particularly with the long-term beneficial effects of megadose dexamethasone. The impact of fingolimod remains to be demonstrated in an ongoing trial. Advances concerning multifocal motor neuropathy, inflammatory plexopathy, and neuropathy with anti -MAG activity are discussed but treatments already recognized as effective should not be changed. Imaging of peripheral nerve progresses.

Quoi de neuf en chirurgie [Novelties in surgery in 2013?].

Multidisciplinary management of colorectal liver metastases allows an increase of about 20% in the resection rate of liver metastases. It includes chemotherapy, interventional radiology and surgery. In 2013, the preliminary results of the in-situ split of the liver associated with portal vein ligation (ALLPS) are promising with unprecedented mean hypertrophy up to 70% at day 9. However, the related morbidity of this procedure is about 40% and hence should be performed in the setting of study protocol only. For pancreatic cancer, the future belongs to the use of adjuvant and neo adjuvant therapies in order to increase the resection rate. Laparoscopic and robot-assisted surgery is still in evolution with significant benefits in the reduction of cost, hospital stay, and postoperative morbidity. Finally, enhanced recovery pathways (ERAS) have been validated for colorectal surgery and are currently assessed in other fields of surgery like HPB and upper GI surgery.

The 2013 Arvid Wretlind lecture: evolving concepts in parenteral nutrition.

Fifty years after the clinical introduction of total parenteral nutrition (TPN) the Arvid Wretlind lecture is an opportunity to critically analyse the evolution and changes that have marked its development and clinical use. The standard crystalline amino acid solutions, while devoid of side effects, remain incomplete regarding their composition (e.g. glutamine). Lipid emulsions have evolved tremendously and are now included in bi- and tri-compartmental feeding bags enabling a true "total" PN provided daily micronutrients are prescribed. The question of exact individual energy, macro- and micro-nutrient requirements is still unsolved. Many complications attributed to TPN are in fact the consequence of under- or over-feeding: the historical hyperalimentation concept is the main cause, along with the use of fixed weight based predictive equations (incorrect in 70% of the critically ill patients). In the late 80's many complications (hyperglycemia, sepsis, fatty liver, exacerbation of inflammation, mortality) were attributed to TPN leading to its near abandon in favour of enteral nutrition (EN). Enteral feeding, although desirable for many reasons, is difficult causing a worldwide recurrence of malnutrition by insufficient feed delivery. TPN indications have evolved towards its use either alone or in combination with EN: several controversial trials published 2011-13 have investigated TPN timing, an issue which is not yet resolved. The initiation time varies according to the country between admission (Australia and Israel), day 4 (Swiss) and day 7 (Belgium, USA). The most important issue may prove to be and individualized and time dependent prescription of feeding route, energy and substrates.

Entre hybris et mélancolie : poétique, esthétique et usages de la liste dans le roman français contemporain (1963-2013)

Forme archaïque, présente dès l'aube de l'écriture; forme ergonomique, présente autour de nous de manière bien plus courante que toute narration; la liste est un objet fascinant, qui ne dévoile jamais autant sa complexité que lorsqu'elle apparaît dans un cadre littéraire. Un cadre permettant de questionner, en les confrontant, la liste et son énonciateur - son sujet. Qui parle quand une liste se dit? Que dit-elle de celui qui l'énonce? Qui parle, lorsque la syntaxe se bouleverse au point de détruire les hiérarchies permettant habituellement de fixer au discours une origine, une destination, une reprise en charge? Il s'agira de répondre à ces questions et donc de passer d'une poétique à une éthique de la liste, afin de montrer que la description d'un tel objet est indissociable de sa contextualisation discursive, sa subjectivisation. Celle-ci traverse, par une constante métalepse (glissement entre les instances de responsabilité du discours), tout le spectre des actants du texte-liste - de la figure d'auteur à celle du lecteur. La spécificité de la liste littéraire se déporte alors dans un espace éthique, puis bientôt thymique, constitué par un faisceau d'oppositions : par exemple, la liste peut être fermée ou ouverte, hyper- ou hypolisible ; signe d'ordre (c'est l'inventaire, où à l'item correspond la chose) comme de désordre (c'est l'accumulation proliférante). Mais le couple oppositionnel le plus fécond est constitué par l'hybris et la mélancolie: hybris, ou l'orgueil de croire à une réinvention du monde par le pouvoir d'une juxtaposition sans limites. Mélancolie, ou miroitement du mot manquant, évidence de l'absence. C'est sous l'égide de cette opposition que je traite un vaste corpus constitué de huit auteurs contemporains, marqués par un XXe siècle catastrophique, où à l'hybris pléthorique de l'expression de la monstruosité et de l'abondance (J-M.G. Le Clézio, Georges Perec, Eric Chevillard) répond la mélancolie d'une absence ontologique : identitaire (Patrick Modiano), épistémologique (Pierre Senges) langagière (Pascal Quignard, Olivia Rosenthal), voire politique (Antoine Volodine).
