The prognosis and fate of the patient in a coma state largely depends on the organization of care at the prehospital and hospital stage. It is important for the doctor to determine the cause of the coma. But before identifying the etiology of a coma, it is necessary to ensure effective maintenance of the vital functions of the patient - respiration and blood circulation, otherwise their serious violations may occur, while the coma itself may be reversible.This textbook includes the educational material for practical classes and individual work of students (Content module 5 «The organization of the emergency on the pre-admission stage in the practice of family doctor»), the tests for initial and final control for academic discipline «General practice – family medicine», recommended literature. The purpose of this textbook is acquiring of knowledge and practical skills of 6th-years students during preparation for classes and final module control. The necessity of this textbook is conditioned by absence of such workbooks, which satisfy requirements of basic parts of academic subject «General practice – family medicine». This textbook can be recommended for students of institutes of higher education (IV accreditation level) in the study of appropriate topic, intern, general practitioner – family doctor, other specialists. 6 LIST OF ABBREVIATIONS ABG arterial blood gas ACEP American College of Emergency Physician AV Atrioventricular BNP B-type natriuretic peptide BP blood pressure BPPV Benign paroxysmal positional (or positioning) vertigo CBF cerebral blood flow CHF congestive heart failure CK creatine kinase CNS central nervous system CO Cardiac output COPD chronic obstructive pulmonary disease CPR cardiopulmonary resuscitation CSF cerebrospinal fluid CT computed tomogaphy DIC disseminated intravascular coagulation DVT deep venous thrombosis ED emergency department EEG Electroencephalography EF ejection fraction EPS electrophysiologic studies GABA gamma-aminobutyric acid GCSE generalized convulsive SE GTCS generalized tonic-clonic seizure ICD implantable cardioverter/defibrillator ICH Intracranial hemorrhage ICP intracranial pressure 7 IM intramuscular IV Intravenous MAP Mean arterial pressure MERRF Myoclonic epilepsy with ragged red fibers MI myocardial infarction MLF medial longitudinal fasciculus MRA magnetic resonance arteriography MRI magnetic resonance image MTLE Mesial Temporal Lobe Epilepsy Syndrome NMDA N-methyl-D-aspartate NMS neurally-mediated syncope NYHA New York Heart Association PET positron emission tomography PVCs premature ventricular contractions RAS reticular activating system SCD sudden cardiac deaths SE status epilepticus SFSR San Francisco Syncope Rule SPECT single photon emission computed tomography SVR Systemic vascular resistance TCA Tricyclic antidepressant TED thromboembolic disease TIAs Transient Ischemic Attacks UTI urinary tract infection VF ventricular fibrillation VOR vestibuloocular reflex VT ventricular tachycardia 8 SYNCOPE. DIZZINESS AND VERTIGO. CARDIOVASCULAR COLLAPSE, CARDIAC ARREST, AND SUDDEN CARDIAC DEATH. SEIZURE I. Theme actuality. First aid for children and adults has great importance for their further treatment and recovering diagnosis at pre-admission stage. And at the same time family doctor always faces a problem: what is better – either to give maximum necessary scope of emergency on the site of the incident or to take the patient to the nearest hospital as soon as possible. According to expert data there is only one decision of this problem. This means give maximum necessary scope of emergency in a short- run and then to admit to specialized hospital. Stabilization of patient’s vital functions is the criteria of emergency scope in the place of the incident. Fundamental factors in this process are timeliness of emergency on the site of the incident, vocational training of a specialist and sufficient medical provision. In this textbook syncope, dizziness and vertigo, cardiovascular collapse, cardiac arrest, and sudden cardiac death and seizure are considered with particular reference to clinical manifestations, differential diagnosis, and treatment [2]. II. Study purposes: to be able to detect the signs of syncope, dizziness and vertigo, cardiovascular collapse, cardiac arrest, and sudden cardiac death, and seizure, to propose a plan of examination and treatment of patients

  • Unarousable Unresponsiveness in Which the Patient Lies with the Eye Closed and Has No Awareness of Self and Surroundings (2)
    Neurological Disease Deborah M Stein, MD, MPH 1. Coma a. Coma is defined as “a state of extreme unresponsiveness, in which an individual exhibits no voluntary movement or behavior” (1). i. Alternatively, coma is a state of unarousable unresponsiveness in which the patient lies with the eye closed and has no awareness of self and surroundings (2). b. Coma lies on a spectrum with other alterations in consciousness – from confusion to delirium to obtundation to stupor to coma and, ultimately, brain death (2). c. To be clearly distinguished from syncope, concussion, or other states of transient unconsciousness coma must persist for at least one hour (2). d. There are 2 important characteristics of the conscious state (3) i. The level of consciousness – “arousal or wakefulness” 1. Regulated by physiological functioning and consists of more primitive responsiveness to the world such as predictable involuntary reflex responses to stimuli. 2. Arousal is maintained by the reticular activating system (RAS) - a network of structures (including the brainstem, the medulla, and the thalamus) ii. The content of consciousness – “awareness” 1. Regulated by cortical areas within the cerebral hemispheres, e. There are two main causes for coma: i. Bihemispheric diffuse cortical or white matter damage or ii. Brainstem lesions bilaterally affecting the subcortical reticular activating systems. f. A huge number of conditions can result in coma. One way to categorize these conditions is to divide them into the anatomic and the metabolic causes of coma. i. Anatomic causes of coma are those conditions that disrupt the normal physical architecture and anatomy, either at the level of the cerebral cortex or the brainstem ii.

  • Neurologic Manifestations of Hypoglycemia
    13 Neurologic Manifestations of Hypoglycemia William P. Neil and Thomas M. Hemmen University of California, San Diego United States of America (USA) 1. Introduction Unlike most other body tissues, the brain requires a continuous supply of glucose. It has very limited endogenous glycogen stores, and does not produce glucose intrinsically.1 Although it accounts for 2% of body weight, the brain utilizes 25% of the body’s glucose due to its high metabolic rate.2, 3 Evidence for the brains sole reliance on glucose came from obtaining a respiratory quotient of one after measuring differences between arterial and venous content of oxygen and carbon dioxide in blood traveling through the brain.4 In the past, neurons were thought to directly metabolize glucose, however, more recent studies suggest astrocytes may play an important role in glucose metabolism.5 Astrocytic foot processes surround brain capillaries, which deliver glucose to the brain. With this, they form the first cellular barrier for entering glucose.5 Astrocytes contain the non-insulin dependent GLUT1 transporter, as well as the insulin dependent GLUT4 transporter, suggesting a possible role for astrocytes in regulating and storing brain glucose in an insulin dependent and independent manner (see figure 1).6-8 In addition to glucose, the brain contains a very limited store of glycogen, (between 0.5 and 1.5 g, or about 0.1% of total brain weight). Unlike peripheral tissue, where glycogen is readily mobilized during hypoglycemia, the brain can only function normally for a limited duration. Glycogen content seems to fall in areas of highest brain metabolic rate, suggesting at least some, albeit limited role as fuel during hypoglycemia.7 Although the brain relies primarily on glucose during normal conditions, it can use ketone bodies during starvation.

THE GENERAL PRINCIPLES OF HISTORY TAKING Irena Zakarija-Grković, MD, FRACGP, IBCLC, PhD A Brief Overview of Clinical Medicine From classical Greek times interrogation of the patient has been considered most important. However, the current emphasis on the use of history taking and physical examination for diagnosis developed only in the 19th century. Until the 19th century, diagnosis was empirical and based on the classical Greek beliefs that all disease had a single cause, an imbalance of the four humours or body fluids (yellow bile, black bile, blood and phlegm). In the 17th century physicians based their opinion on a history provided by an apothecary (assistant) and rarely saw the patients themselves. Thomas Sydenham (1624-1689) began to practise more modern bedside medicine basing his treatment on experience and not theory. A renaissance in clinical methods began with the concept of Battista Morgagni (1682-1771) that disease was not generalised but arose in organs, a conclusion published in 1761. Leopold Auenbrugger invented chest tapping (percussion) to detect disease in the same year.

  • Postconcussional Disorder and Loss of Consciousness
    Postconcussional Disorder and Loss of Consciousness Stephen D. Anderson, MD, FRCP(C) Postconcussional disorder (PCD) has been described in the psychiatric, neuro- logical, neuropsychological, and rehabilitation medicine literature for many years. PCD has recently been introduced into DSM-IV, appearing in an appendix that contains a number of proposals for new categories and axes that were suggested for possible inclusion in DSM-IV. There are some major difficulties with the proposed criteria for PCD. This article explores some of these difficulties, partic- ularly focusing on the criteria of loss of consciousness (LOC). A review of the literature demonstrates that LOC is not necessary for PCD to occur. The major difficulty with the DSM-IV criteria is the definition of concussion. The article suggests that, instead, the criteria for mild traumatic brain injury, as defined by the American Congress of Rehabilitation Medicine, may be more appropriate. Postconcussional disorder (PCD) has been symptoms include headache pain, nausea. described in the medical literature for dizziness or vertigo. unsteadiness or poor over a century.

  • Types of Brain Dysfunction in Critical Illness Robert D
    Neurol Clin 26 (2008) 469–486 Types of Brain Dysfunction in Critical Illness Robert D. Stevens, MD*, Paul A. Nyquist, MD, MPH Departments of Anesthesiology Critical Care Medicine, Neurology, and Neurological Surgery, Johns Hopkins University School of Medicine, Meyer 8-140, 600 North Wolfe Street, Baltimore, MD 21287, USA Many patients in the ICU develop a global alteration in cognitive func- tion that may be structural or metabolic in origin [1]. Terms used to describe these disturbances include delirium, acute confusional state, organic brain syndrome, acute organic reaction, cerebral insufficiency, brain failure, ICU psychosis, and encephalopathy. Etiology-specific terms, such as septic encephalopathy or hepatic encephalopathy, have been used when there is a strong presumption regarding the causative mechanism. It has been pos- tulated that many of these disorders are clinical expressions of a pathophys- iologic spectrum, collectively referred to as ‘‘critical illness brain syndrome’’ [2], ‘‘critical illness–associated cognitive dysfunction’’ [3], or ‘‘critical illness encephalopathy’’ [1]. Recently, there has been an effort to rationalize this terminology and to classify brain dysfunction in the ICU as either delirium or coma, using validated clinical criteria [4–7]. Coma Clinical assessment In the clinical realm consciousness is described in terms of two primary neurologic functions: arousal or wakefulness, and awareness of self and of the environment [8]. Awareness is the content of consciousness and includes multiple cognitive domains including perception, attention, memory, This is an updated version of an article that originally appeared in Critical Care Clinics, volume 22, issue 4. * Corresponding author.
