  • 'Emergency Medicine Thinker' is a practical pocketbook that provides important considerations for the practice of emergency medicine. Based on the popular website created by the authors, 'emDocs.net', it covers practical thinking rules that can be applied on an emergency medicine shift and provides approaches to common and life-threatening diseases in the ED that physicians see on a regular basis. Easy to read with quick access to information, and full of essential tips and pearls from experts on the emergency frontlines, this is a handbook that can be used at the bedside on shift. Part 1 of the book explores the EM decision-making process and why it's important from a myriad of central and talented emergency physicians. Part 2 features over 170 pearls for the frontline EM clinician. This book is a must-have for anyone working in emergency medicine.

  • Summary

    This chapter looks at Plato’s take on the nomos-phusis antithesis in his Laws. He argues that the goal of the Laws, of legislating in accordance with nature, should be distinguished from the much-studied idea of 'natural law' in two ways. First, in the relevant parts of the Laws, the focus is primarily the right way to conduct an activity, legislation, rather than its product (laws or law). Secondly, the Laws draws a comparison with other specialised or technical activities that can be performed well or badly, such as medicine or building. Legislation is natural, among other things, when it is undertaken in a certain ‘natural’ order, from the starting point of life to death. This order ensures that no stage of life is ignored during the legislative process and thus guarantees its comprehensiveness. Plato’s comparison between the legislator and other craftsmen presents a view of natural procedure within an art or profession: the craftsman is not subjected to constraints that are external to the subject matter and he is able to give full attention to the objectives and questions that belong to his craft. Finally, the legislation considered here is ‘natural’ without being underpinned by theology.

  • Lower neck organs at risk sparing in nasopharyngeal carcinoma using hybrid volumetric-modulated arc therapy (hybrid-VMAT): a case report

  • Introduction:

    Nasopharyngeal carcinoma (NPC) is a prevalent disease in Southern China. Radiation therapy remains the primary treatment modality for NPC due to its high radiation sensitivity. Conventional volumetric-modulated arc therapy (VMAT) can achieve excellent target volume coverage and superior conformal dose distributions while sparing organs at risk (OARs). However, VMAT may also produce substantial volume of low-dose region in the surrounding normal tissue. Our oncology centre has incorporated the concept of anterior cervical field with VMAT in clinical practice of NPC treatment planning. The purpose of this treatment-comparison case study is to demonstrate the lower neck OARs sparing ability of hybrid volumetric-modulated arc therapy (hybrid-VMAT) over conventional VMAT for NPC.

    Methods:

    Four patients diagnosed with NPC of different clinical lymph node staging (N staging) were enrolled for this treatment-comparison case study. Planning target volumes and OARs were delineated with reference to Radiation Therapy Oncology Group (RTOG) 0225/0615. Additional OARs from lower neck region, including thyroid, trachea, cervical spine and pharyngeal constrictor muscles (PCMs), were also delineated. Two treatment techniques, hybrid-VMAT and VMAT, were created for each patient’s dataset.

    Results and findings:

    Both treatment techniques produced adequate target coverage and reduced radiation dose to the OARs as suggested in RTOG 0225/0615. Hybrid-VMAT plans achieved superior dose reduction in larynx, oesophagus, middle PCM, inferior PCM, cervical spine and trachea comparing with VMAT plans. Hence, the clinical usability and functional outcome of hybrid-VMAT should be further investigated for NPC radiation therapy.

  • A 23-year-old female presents with right lower quadrant pain that has been intermittent for the past several days. The pain suddenly worsened 1 hour ago. She denies vaginal bleeding or discharge, dysuria, fever, and back pain, but she has had several episodes of nausea with nonbloody, nonbilious vomiting. On examination, she is tender in the right lower quadrant, but her abdomen is not rigid.

  • A 32-year-old male presents with diffuse myalgias, weakness, and dark urine for 1 day. The patient states he recently started a new exercise program. He is hemodynamically stable, and his physical examination reveals diffuse muscle tenderness. His creatine kinase (CK) returns at 8,000 international units per liter (IU/L), and his urinalysis reveals blood but only three red blood cells (RBCs) on microscopy.

  • Trauma is a leading cause of death and disability around the world, and the leading cause of death in those aged under forty-five years. Conditions such as airway obstruction, hemorrhage, pneumothorax, tamponade, bowel rupture, vascular injury, and pelvic fracture can cause death if not appropriately diagnosed and managed. This essential book provides emergency physicians with an easy-to-use reference and source for traumatic injury evaluation and management in the emergency department. It covers approaches to common, life-threatening, and traumatic diseases in the emergency department, for use on shift and as a reference for further learning. Each chapter includes a succinct overview of common traumatic injuries, with evaluation and management pearls and pitfalls. Highly illustrated with images from one of the busiest trauma centers in the US, and featuring expert contributions from a diverse set of attending physicians, this is an essential text for all emergency medicine practitioners.

  • Plato's Meno and Phaedo are two of the most important works of ancient western philosophy and continue to be studied around the world. The Meno is a seminal work of epistemology. The Phaedo is a key source for Platonic metaphysics and for Plato's conception of the human soul. Together they illustrate the birth of Platonic philosophy from Plato's reflections on Socrates' life and doctrines. This edition offers new and accessible translations of both works, together with a thorough introduction that explains the arguments of the two dialogues and their place in Plato's thought.
