Objective:
We compared the rates of hospital-onset secondary bacterial infections in patients with coronavirus disease 2019 (COVID-19) with rates in patients with influenza and controls, and we investigated reports of increased incidence of Enterococcus infections in patients with COVID-19.
Design:Retrospective cohort study.
Setting:An academic quaternary-care hospital in San Francisco, California.
Patients:Patients admitted between October 1, 2019, and October 1, 2020, with a positive SARS-CoV-2 PCR (N = 314) or influenza PCR (N = 82) within 2 weeks of admission were compared with inpatients without positive SARS-CoV-2 or influenza tests during the study period (N = 14,332).
Methods:National Healthcare Safety Network definitions were used to identify infection-related ventilator-associated complications (IVACs), probable ventilator-associated pneumonia (PVAP), bloodstream infections (BSIs), and catheter-associated urinary tract infections (CAUTIs). A multiple logistic regression model was used to control for likely confounders.
Results:COVID-19 patients had significantly higher rates of IVAC and PVAP compared to controls, with adjusted odds ratios of 4.7 (95% confidence interval [CI], 1.7–13.9) and 10.4 (95 % CI, 2.1–52.1), respectively. COVID-19 patients had higher incidence of BSI due to Enterococcus but not BSI generally, and whole-genome sequencing of Enterococcus isolates demonstrated that nosocomial transmission did not explain the increased rate. Subanalyses of patients admitted to the intensive care unit and patients who required mechanical ventilation revealed similar findings.
Conclusions:COVID-19 is associated with an increased risk of IVAC, PVAP, and Enterococcus BSI compared with hospitalized controls, which is not fully explained by factors such as immunosuppressive treatments and duration of mechanical ventilation. The mechanism underlying increased rates of Enterococcus BSI in COVID-19 patients requires further investigation.

The Parisian Pierre de L’Estoile was an obsessive compiler of politically motivated, obscene ephemera during the reign of King Henri III (r. 1574–89). This article explores how and why L’Estoile kept on adding to a vast archive of “vilain” (“vile”) materials that he purportedly despised. Examining L’Estoile’s manuscripts at close quarters, the article traces a complex practice of censure and self-censorship alongside similar practices by contemporary writers (Henri Estienne and Pierre de Brantôme). L’Estoile’s contribution to the history of sexuality is that of a self-aware critic, legitimating his compulsion to disavow the obscenities he chose to preserve.

There are several novels that pique our common interest, but Zola's ambition to put a ‘scientific aim above all others' in his 19th-century novel Thérèse Raquin provides a particularly interesting topic for collective reflection. After being criticised for vulgarity, in the preface to the second edition of his work Zola justified his portrayal of a gruesome ménage àtrois as being analogous to the ‘analytical work that surgeons conduct on cadavers'. Criticism of Zola's work often focuses on whether he achieves the degree of reductionism and determinism that he allegedly strove for or whether, in fact, his predilections for the gothic and fantastic overshadow the novel's scientific, ‘surgical’ veneer. Similarly, psychiatric case notes often begin with a highly formulaic scientific account, yet on closer inspection digress to read more like a tragic novel.

Objective:
The Canadian Association of Emergency Physicians (CAEP) sepsis guidelines created by the CAEP Critical Care Practice Committee (C4) and published in the Canadian Journal of Emergency Medicine (CJEM) form the most definitive publication on Canadian emergency department (ED) sepsis care to date. Our intention was to identify which of the care items in this document are specifically necessary in the ED and then to provide these items in a tiered checklist that can be used by any Canadian ED practitioner.
Methods:Practice points from the CJEM sepsis publication were identified to create a practice point list. Members of C4 then used a Delphi technique consensus process over May to October 2009 via e-mail to create a tiered checklist of sepsis care items that can or could be completed in a Canadian ED when caring for the septic shock patient. This checklist was then assessed for use by a survey of ED practitioners from varying backgrounds (rural ED, community ED, tertiary ED) from July to October 2010.
Results:Twenty sepsis care items were identified in the CAEP sepsis guidelines. Fifteen items were felt to be necessary for ED care. Two levels of checklists were then created that can be used in a Canadian ED. Most ED physicians in community and tertiary care centres could complete all parts of the level I sepsis checklist. Rural centres often struggle with the ability to obtain lactate values and central venous access. Many items of the level II sepsis checklist could not be completed outside the tertiary care centre ED.
Conclusion:Sepsis care continues to be an integral and major part of the ED domain. Practice points for sepsis care that require specialized monitoring and invasive techniques are often limited to larger tertiary care EDs and, although heavily emphasized by many medical bodies, cannot be reasonably expected in all centres. When the resources of a centre limit patient care, transfer may be required.
Liste de contrôle de l’Association canadienne des médecins d’urgence concernant le traitement de la sepsie: optimisation de la prise en charge de la sepsie au sein des services des urgences canadiens

Objectif:
Les directives de l'Association canadienne des médecins d'urgence (ACMU) relatives à la sepsie, créées par le Critical Care Practice Committee de l'ACMU (C4) et publiées dans le Canadian Journal of Emergency Medicine (CJEM), constituent la plus importante publication consacrée à la prise en charge de la sepsie au sein des services des urgences (SU) canadiens. Notre intention consistait à identifier lesquels, parmi les éléments de prise en charge proposés dans ce document, sont spécifiquement nécessaires au sein du SU et de présenter ensuite ces éléments sous la forme d'une liste de contrôle à plusieurs niveaux pouvant être utilisée par n'importe quel praticien d'un SU canadien.
Méthodes:Les points pratiques de la publication du CJEM consacrée à la sepsie ont été identifiés afin de générer une liste pratique en plusieurs points. Les membres du C4 ont ensuite eu recours, de mai à octobre 2009, à une procédure de consensus selon la technique Delphi, par courriel, en vue de créer une liste de contrôle à plusieurs niveaux relatives aux eléménts de la prise en charge de la sepsie pouvant ou non être assurés au sein d'un SU canadien lors de la prise en charge d'un patient victime d'un choc septique. Cette liste de contrôle a ensuite été évaluée en vue de son utilisation par le biais d'un questionnaire adressé à des praticiens de SU travaillant dans divers contextes (SU rural, SU communautaire, SU tertiaire), cela de juillet à octobre 2010.
Résultats:Vingt éléments de la prise en charge de la sepsie ont été identifiés dans les directives de l'ACMU relatives à la sepsie. Quinze eléménts ont été jugés nécessaires pour la prise en charge dans le cadre d'un SU. On a ensuite crée deux niveaux de liste de contrôle pouvant être utilisés dans un SU canadien. La plupart des médecins urgentistes travaillant dans des centres de soins communautaires et tertiaires ont pu réaliser toutes les parties de la liste de contrôle de niveau I pour le sepsis. Les centres ruraux rencontrent souvent des difficultés en ce qui concerne la possibilité d'obtention d'un dosage du lactate valeurs et d'un accès veineux central. Un grand nombre d'éléments de la liste de contrôle de niveau II pour le sepsis n'ont pas pu être réalisés en dehors des SU de centres de soins tertiaires.
Conclusion:La prise en charge de la sepsie fait toujours partie intégrante et constitue un élément majeur du domaine des SU. Les points pratiques pour la prise en charge de la sepsie qui requièrent un monitorage spécialisé et des techniques invasives sont souvent limités aux SU de soins tertiaires plus importants et, bien que bon nombre de corps médicaux soulignent leur importance, ne peuvent pas raisonnablement être attendus dans tous les centres. Lorsque les ressources d'un centre limitent la prise en charge du patient, un transfert peut s'avérer nécessaire.

Introduction:
La prise en charge optimale du sepsis grave dans les départements d'urgence a connu une évolution rapide. Le but des présentes lignes directrices est de revoir pour le bénéfice des médecins d'urgence canadiens les principes clés qui régissent la prise en charge du sepsis grave en se fondant sur un système de classification fondé sur des preuves.
Méthodes:Ce sont les membres du comité de l'ACMU pour les soins critiques, ou comité C4 (pour CAEP Critical Care Interest Group) qui ont déterminé les secteurs clés de la prise en charge des patients atteints de sepsis. Chaque membre du C4 avait pour tâche de répondre à une question qui lui avait été assignée après avoir fait un survol de la littérature établie selon le système de classification Oxford, après quoi, chaque secteur faisait l'objet d'une seconde révision par un autre membre du C4. D'autres experts de l'extérieur ont procédé à un troisième examen et les modifications ont été déterminées par voie de consensus. La classification reposait sur des publications révisées par des pairs uniquement, et là où les preuves étaient insuffisantes pour répondre à une question importante, le groupe a proposé un «point pratique».
Résultats:Le projet a débuté en 2005 et a pris fin en décembre 2007. Les secteurs clés qui ont été passés en revue incluent la définition du terme sepsis, l'utilisation des interventions effractives, la réanimation liquidienne, l'utilisation d'agents vasopresseurs/inotropes, l'importance des prélèvements pour culture aux départements d'urgence, l'antibiothérapie et le contrôle des sources. Parmi les autres secteurs examinés, mentionnons l'utilisation des corticostéroïdes, la protéine C activée, les transfusions et la ventilation mécanique.
Conclusion:La prise en charge précoce du sepsis dans les départements d'urgence est extrêmement importante pour améliorer le pronostic des patients. L'énoncé de position du C4 sur le sepsis fournit un cadre de travail afin d'améliorer les soins prodigués à cette population de patients dans les départements d'urgence.

Introduction:
Optimal management of severe sepsis in the ED has evolved rapidly. The purpose of these guidelines is to review key management principles for Canadian emergency physicians, utilizing an evidence-based grading system.
Methods:Key areas in the management of septic patents were determined by members of the CAEP Critical Care Interest Group (C4). Members of C4 were assigned a question to be answered after literature review, based on the Oxford grading system. After completion, each section underwent a secondary review by another member of C4. A tertiary review was conducted by additional external experts, and modifications were determined by consensus. Grading was based on peer-reviewed publications only, and where evidence was insufficient to address an important topic, a “practice point” was provided based on group opinion.
Results:The project was initiated in 2005 and completed in December 2007. Key areas which were reviewed include the definition of sepsis, the use of invasive procedures, fluid resuscitation, vasopressor/inotrope use, the importance of culture acquisition in the ED, antimicrobial therapy and source control. Other areas reviewed included the use of corticosteroids, activated protein C, transfusions and mechanical ventilation.
Conclusion:Early sepsis management in the ED is paramount for optimal patient outcomes. The CAEP Critical Care Interest Group Sepsis Position Statement provides a framework to improve the ED care of this patient population.

Summary
CELLULAR PHYSIOLOGY
Membranes
What is the main function of the cell membrane?
To control the entry and exit of molecules from the cell and so regulate the intracellular environment.
Describe the basic structure of a cell membrane.
The cell membrane consists of a continuous lipid bilayer studded with protein molecules.
How does this structure allow control of the movement of molecules into and out of the cell?
The lipid bilayer has hydrophilic groups facing outwards while hydrophobic groups face each other across the middle. Most large water-soluble molecules, charged molecules and ions cannot cross the lipid barrier. Size, charge and water-solubility all decrease the ability of a molecule crossing the fatty membrane. These substances depend on the membrane proteins for their entry and exit from the cell. These proteins can act as channels sensitive to voltage or ligandbinding or as energy-dependent pumps. Fat-soluble substances like oxygen and carbon dioxide can cross easily as can water.
What is the overall charge of the outer surface of the cell membrane?
Negative.
What part of the membrane structure is responsible for this negative charge?
The cell has a “glycocalyx” formed by membrane carbohydrates, which are negatively charged. These carbohydrates also act as receptor substrates and can bind to carbohydrates on other cells.
Ion Channels
What is the basic structure of an ion channel?
They are proteins, which form tubular structures with a central pore which traverses the cell membrane and can allow communication between the extracellular fluid and the intracellular compartment.

Summary
GROWTH AND DIFFERENTIATION
Hyperplasia and Hypertrophy
Define hypertrophy.
The growth of a tissue or organ because cells increase in size without cell replication.
Define hyperplasia.
The growth of a tissue or organ because there is an increase in the number of cells due to cell division.
Give a physiological and pathological cause of hypertrophy.
Muscles undergo hypertrophy with exercise while cardiomyopathies involve heart muscle hypertrophy.
Give a physiological and pathological cause of hyperplasia.
Hyperplasia takes place in the breast during puberty and pregnancy while adrenal hyperplasia characterises Cushing's disease.
Can you name any conditions in which hypertrophy and hyperplasia occur in the same organ?
Benign prostatic enlargement.
Grave's disease of the thyroid.
What is autonomous hyperplasia?
Proliferation in the absence of a demonstrable stimulus as in psoriasis and Paget's disease of bone. This falls very close to the definition of neoplasia.
Metaplasia
Define metaplasia.
The reversible change of one fully differentiated cell type to another.
Can you give an example?
In Barrett's oesophagus the distal stratified squamous epithelium is replaced by columnar epithelium like that present in the proximal stomach.
What mechanism is thought to be responsible?
Prolonged gastro-oesophageal reflux leads to inflammation and eventually ulceration. Healing occurs by re-epithelialisation, which in the acidic environment created by gastro-oesophageal reflux disease (GORD) differentiate into gastric or intestinal type epithelium. These are more resistant to injury from gastric contents.

This book is designed specifically for candidates preparing for the MRCS Viva examination. The format of the exam has been used in the book's structure, with over 1000 questions to illustrate the key points of over 200 topics. The book has been divided into 6 main chapters corresponding to a viva 'station' in the exam. Each chapter begins with a check-list of the main topics and themes covered by the exam, and information is then subdivided logically within the chapter itself. Key 'pass-or-fail' concepts are covered, and in some cases, topics are covered in more detail than will be asked in the exam, so the candidate can be confident that they will be fully prepared.

Summary
HEAD AND NECK
Salivary Glands
What important structures lie within the parotid gland?
Facial nerve.
Retro-mandibular vein.
External carotid artery – bifurcating into its two terminal branches, the maxillary artery and the superficial temporal artery.
Can you outline the surface markings of the parotid gland for?
Using a marker begin a line from in front of the tragus of the ear and draw it into the middle of the cheek below the zygomatic arch. From here proceed downwards and backwards to a point 1 cm in front of the angle of the mandible. Then continue upwards and backwards 1–2 cm into the neck including the mastoid process. Finally draw your line around the ear to join up to the point from where we started. You will now have drawn a shape that approximates the position of the parotid.
What are the potential complications of parotid surgery?
Facial nerve damage.
Haematoma.
Frey's syndrome (gustatory sweating).
Numbness of the pinna (due to sacrifice of the greater auricular nerve).
Salivary fistula (in superficial parotidectomy only, as the cut gland left behind continues to secrete saliva).
Wound dimple.
During surgery how would you locate the facial nerve?
This can be done in three different ways:
by identifying the tip of the tragal cartilage with during the dissection – the facial nerve lies 1 cm inferior and deep to this cartilage;

Summary
PERI-OPERATIVE CARE
The Diabetic Patient
How do you assess a diabetic patient in the clinic?
Take a history of the type of diabetic control used, the dosage schedule and the adequacy of control. Particular attention is paid to the propensity to develop hyperglycaemia, ketosis and hypoglycaemia. Ask specifically about the complications of diabetes: nephropathy, sensory and autonomic neuropathy, hypertension, peripheral and coronary arterial disease and retinopathy. The patient looking for these complications is then examined. Look for ongoing infection.
How do you manage the diabetic patient once they are on the ward?
Patients with diabetes often have gastroparesis, and they should fast at least 12 hours before elective surgery. Always try to put the patient first on the list. Patients with diet-controlled diabetes usually just require glucose monitoring. Patients on oral hypoglycaemic agents should have those agents discontinued on the day of surgery. Sulphonyl urea drugs should be withheld at least 1 day before surgery, because of their long half-life. For those on insulin prescribe 5% dextrose with potassium and start sliding scale insulin infusion. Continue the insulin and dextrose infusion until the patient has had a second meal with their normal dose of subcutaneous insulin post-operatively.
What are the potential operative complications in the diabetic patient?
Infections: diabetics are prone to infection at the surgical site and elsewhere.
Wound healing: this is impaired in diabetics due in part to microvascular disease.
Cardiovascular complications: due to macrovascular disease.
