REVIEW
Guy Cammu
Purpose of Review: The purpose of this review is to assess how sugammadex impacts postoperative residual curarization using appropriate doses based on neuromuscular transmission monitoring and whether the advantages of sugammadex versus neostigmine outweigh its higher cost. Recent Findings: An accurate assessment of neuromuscular blockade with monitoring is necessary before selecting neostigmine versus sugammadex for reversal at the end of surgery to overcome incomplete neuromuscular recovery...

Toxic myopathies are a group of pathologies characterized by a structural and/or functional disturbance of muscles induced by an exogenous agent. The most frequent are those induced by drugs used in clinical practice. Illegal drugs, pesticides, solvents, metals and even physical and gaseous agents can cause this kind of disease and exert toxicity on muscle tissues. Some toxins from animals, plants or micro-organisms are potent myotoxic agents, which can lead to fatal complications. Respiratory arrest and rhabdomyolysis are often referred to as the ultimate complications of these pathologies...

A pesar de la legislación de Otto von Bismarck (1815-1898) sobre derechos de seguridad social formulada en 1883 en Alemania donde se señala que es deber del Estado promover el bienestar de todos los miembros de la sociedad, particularmente de los más débiles y necesitados utilizando los medios con los que dispone, y las propuestas de leyes contra accidentes expedidas el 30 de abril de 1904 en el Estado de México, en el México del porfiriato no se consideró brindar atención médica formal a los trabajadores, salvo algunas empresas ferrocarrileras, no se construyeron hospitales para atender a pacientes con enfermedades laborales...

There are currently no functional neuromuscular junction (hNMJ) systems composed of human cells that could be used for drug evaluations or toxicity testing in vitro. These systems are needed to evaluate NMJs for diseases such as amyotrophic lateral sclerosis, spinal muscular atrophy or other neurodegenerative diseases or injury states. There are certainly no model systems, animal or human, that allows for isolated treatment of motoneurons or muscle capable of generating dose response curves to evaluate pharmacological activity of these highly specialized functional units...

BACKGROUND: The extensive use of neuromuscular blocking agents (NMBAs) during surgical procedures still leads to potential residual paralyzing effects in the postoperative period. Indeed, neuromuscular monitoring in an intra-operative setting is strongly advocated. Acetylcholinesterase inhibitors can reverse muscle block, but their short half-life may lead to residual curarization in the ward, especially when intermediate or long-acting NMBAs have been administered. Sugammadex is the first selective reversal drug for steroidal NMBAs; it has been shown to give full and rapid recovery of muscle strength, thus minimizing the occurrence of residual curarization...

Previous research has revealed that fetuses detect and respond to extrauterine stimuli such as maternal movement and speech, but little attention has been cast on how fetuses may directly influence and respond to each other in the womb. This study investigated whether motor activity of E20 rat fetuses influenced the behavior of siblings in utero. Three experiments showed that; (a) contiguous siblings expressed a higher frequency of synchronized movement than noncontiguous siblings; (b) fetuses that lay between two siblings immobilized with curare showed less movement relative to fetuses between saline or uninjected controls; and (c) fetuses between two siblings behaviorally activated by the opioid agonist U50,488 also showed less activity and specific behavioral changes compared to controls...

Claude Bernard (1813-1878) was fascinated by the pharmacological mechanisms of poisons. In particular, using a huge amount of ingenious and robust experiments, he demonstrated the peripheral toxic action of the natural compound curare. His work generated controversies in a period where scientific methodology and technical development followed the progression of concepts and ideas. From his intense debates with Albert Vulpian emerged the location of curare's toxicity at the neuromuscular junction. These two fascinating scientists could not imagine how important were these discoveries which allowed John Langley to propose the concept of receptor early in the 20th century...

The biological activity of Rhinella icterica toxic secretion (RITS) was evaluated on chick neuromuscular junctions, rat heart́s tissue and mice hippocampal slices. At chick biventer cervicis preparation, RITS (5, 10 and 20μg/mL) produced a concentration-independent irreversible neuromuscular blockade, which was preceded by a transitory increase of muscle twitch tension with the lowest concentration, in 120min recordings. In this set of experiments, RITS incubation partially prevented the curare neuromuscular blockade...

This third installment of the history of basic airway management discusses the transitional-"progressive"-years of anesthesia from 1904 to 1960. During these 56 yr, airway management was provided primarily by basic techniques with or without the use of a face mask. Airway maneuvers were inherited from the artisanal era: head extension and mandibular advancement. The most common maneuver was head extension, also used in bronchoscopy and laryngoscopy. Basic airway management success was essential for traditional inhalation anesthesia (ether, chloroform) and for the use of the new anesthetic agents (cyclopropane, halothane) and intravenous drugs (thiopental, curare, succinylcholine)...

OBJECTIVES: Life after severe burns is conditioned by the remaining sequelae. The pathophysiology and risk factors of Heterotopic Ossification (HO) after burns are still poorly understood. The aim of this study was to determine: 1) the incidence of HO after burns and 2) the risk factors associated with HO development, in a large retrospective study. METHODS: A case-control study of patients admitted to the burns intensive care unit of Percy Hospital, Paris, from the 1st January 2009 to the 31st December 2013 and then admitted to one of three centres specialised in the rehabilitation of patients with burns...

Behavioral homology is often assumed to involve similarity in underlying neuronal mechanisms. Here, we provide a counterexample where homologous behaviors are produced by neurons with different synaptic connectivity. The nudibranch molluscs Melibe leonina and Dendronotus iris exhibit homologous swimming behaviors, consisting of alternating left and right body flexions. The swim central pattern generators (CPGs) in both species are composed of bilaterally symmetric interneurons, which are individually identified and reciprocally inhibit their contralateral counterparts, contributing to left-right burst alternation in the swim motor patterns...

For the past two years, I have taught a seminar on medical research scandals. The syllabus looks like a highlight reel of exploitation and abuse: children fed plutonium-laced breakfast cereal, prisoners dosed with the active ingredient in Agent Orange, mental patients given psychedelic drugs and massive electroconvulsive therapy before being sent into curare-induced paralysis and a coma. I designed the seminar to crush the idealism of future physicians by illuminating the dark patterns that research scandals typically follow...

INTRODUCTION: Anesthetic management of patients with Duchenne muscular dystrophy (DMD) is complicated because these patients are more sensitive to nondepolarizing neuromuscular blocking agents (NMBAs) and are vulnerable to postoperative complications, such as postoperative residual curarization and respiratory failure. Sugammadex is a new reversal agent for aminosteroidal NMBAs, but its safety in children is controversial. CLINICAL FEATURES: An 11-year-old boy with DMD underwent general anesthesia for a percutaneous nephrolithotomy...
