    DISORDERS OF SERUM SODIUM CONCENTRATION Bruce M. Tune, M.D. Stanford, California Regulation of Sodium and Water Excretion Sodium: glomerular filtration, aldosterone, atrial natriuretic factors, in response to the following stimuli. 1. Reabsorption: hypovolemia, decreased cardiac output, decreased renal blood flow. 2. Excretion: hypervolemia (Also caused by adrenal insufficiency, renal tubular disease, and diuretic drugs.) Water: antidiuretic honnone (serum osmolality, effective vascular volume), renal solute excretion. 1. Antidiuresis: hyperosmolality, hypovolemia, decreased cardiac output. 2. Diuresis: hypoosmolality, hypervolemia ~ natriuresis. Physiologic changes in renal salt and water excretion are more likely to favor conservation of normal vascular volume than nonnal osmolality, and may therefore lead to abnormalities of serum sodium concentration.

With severe increase in serum potassium, dysrhythmias and atrioventricular and bundle branch blocks can be seen on electrocardiogram. Although cardiac arrest is a worrisome consequence of untreated hyperkalemia, rarely does hyperkalemia electrocardiographically manifest as acute ischemia. Case presentation: We present a case of acute renal failure complicated by malignant hyperkalemia and eventual ventricular fibrillation cardiac arrest. Recognition of this disorder was delayed secondary to an initial ECG pattern suggesting an acute ST segment elevation myocardial infarction (STEMI). Emergent coronary angiography performed showed no evidence of coronary artery disease. Conclusions: Pseudo-STEMI patterns are rarely seen in association with acute hyperkalemia and are most commonly described with patient without acute cardiac symptomatology. This is the first such case presenting concurrently with cardiac arrest. A brief review of this rare pseudo-infarct pattern is also given.

  • HANDOUT #1 CONCEPT INTRODUCTION PRESENTATION: PERFUSION Topic Description Definition of Perfusion the Passage of Oxygenated Capi
    HANDOUT #1 CONCEPT INTRODUCTION PRESENTATION: PERFUSION Topic Description Definition of Perfusion The passage of oxygenated capillary blood through body tissues. Peripheral perfusion is passage (flow) of blood to the extremities of the body. Central perfusion is passage (flow) of blood to major body organs, including the heart and lungs. Scope of Perfusion Perfusion can be viewed on a continuum as adequate on one end and inadequate, decreased, or impaired on the other. Decreased Perfusion can range from minimal to severe. Ischemia refers to decreased Perfusion, while infarction is complete tissue death due to severe decreased Perfusion. Risk Factors/Populations at Risk for Examples of risk factors or populations at risk Impaired Perfusion for impaired Perfusion can be categorized as modifiable (can be changed) and nonmodifiable (cannot be changed) Modifiable factors include: • Obesity • Lack of physical activity/sedentary lifestyle • Smoking Nonmodifiable factors include age, gender, and race/ethnicity. Groups at risk for impaired Perfusion include those who are of advanced age (due to less elastic arterial vessels as a result of aging) and those who are African American and Hispanic. These racial/ethnic groups are most at risk for chronic diseases that can affect Perfusion such as diabetes mellitus, hypertension, hyperlipidemia, and peripheral vascular disease. The cause of these variations is not known, but dietary and environmental factors may contribute to the higher incidence of chronic disease in these groups. Newborns and infants who have congenital heart anomalies are also at risk for impaired central Perfusion. Many of these defects can be surgically repaired to regain adequate Perfusion. Physiologic Consequences of Impaired Consequences of impaired Perfusion vary Perfusion depending on the degree of impairment.

  • What Are the Health Effects from Exposure to Carbon Monoxide?
    CO Lesson 2 CARBON MONOXIDE: LESSON TWO What are the Health Effects from Exposure to Carbon Monoxide? LESSON SUMMARY Carbon monoxide (CO) is an odorless, tasteless, colorless and nonirritating Grade Level: 9 – 12 gas that is impossible to detect by an exposed person. CO is produced by the Subject(s) Addressed: incomplete combustion of carbon-based fuels, including gas, wood, oil and Science, Biology coal. Exposure to CO is the leading cause of fatal poisonings in the United Class Time: 1 Period States and many other countries. When inhaled, CO is readily absorbed from the lungs into the bloodstream, where it binds tightly to hemoglobin in the Inquiry Category: Guided place of oxygen. CORE UNDERSTANDING/OBJECTIVES By the end of this lesson, students will have a basic understanding of the physiological mechanisms underlying CO toxicity. For specific learning and standards addressed, please see pages 30 and 31. MATERIALS INCORPORATION OF TECHNOLOGY Computer and/or projector with video capabilities INDIAN EDUCATION FOR ALL Fires utilizing carbon-based fuels, such as wood, produce carbon monoxide as a dangerous byproduct when the combustion is incomplete. Fire was important for the survival of early Native American tribes. The traditional teepees were well designed with sophisticated airflow patterns, enabling fires to be contained within the shelter while minimizing carbon monoxide exposure. However, fire was used for purposes other than just heat and cooking. According to the historian Henry Lewis, Native Americans used fire to aid in hunting, crop management, insect collection, warfare and many other activities. Today, fire is used to heat rocks used in sweat lodges.

  • Electrolyte Disorders and Arrhythmogenesis
    Cardiology Journal 2011, Vol. 18, No. 3, pp. 233–245 Copyright © 2011 Via Medica REVIEW ARTICLE ISSN 1897–5593 Electrolyte disorders and arrhythmogenesis Nabil El-Sherif1, Gioia Turitto2 1State University of NY, Downstate Medical Center and NY Harbor VA Healthcare System, Brooklyn, NY, USA 2Methodist University Hospital, Brooklyn, NY, USA Abstract Electrolyte disorders can alter cardiac ionic currents kinetics and depending on the changes can promote proarrhythmic or antiarrhythmic effects. The present report reviews the mecha- nisms, electrophysiolgical (EP), electrocardiographic (ECG), and clinical consequences of elec- trolyte disorders. Potassium (K+) is the most abundent intracellular cation and hypokalemia is the most commont electrolyte abnormality encountered in clinical practice. The most signifcant ECG manifestation of hypokalemia is a prominent U wave. Several cardiac and + non cardiac drugs are known to suppress the HERG K channel and hence the IK, and especially in the presence of hypokalemia, can result in prolonged action potential duration and QT interval, QTU alternans, early afterdepolarizations, and torsade de pointes ventricu- lar tachyarrythmia (TdP VT). Hyperkalemia affects up to 8% of hospitalized patients mainly in the setting of compromised renal function. The ECG manifestation of hyperkalemia de- pends on serum K+ level. At 5.5–7.0 mmol/L K+, tall peaked, narrow-based T waves are seen. At > 10.0 mmol/L K+, sinus arrest, marked intraventricular conduction delay, ventricular techycardia, and ventricular fibrillation can develop. Isolated abnormalities of extracellular calcium (Ca++) produce clinically significant EP effects only when they are extreme in either direction. Hypocalcemia, frequently seen in the setting of chronic renal insufficiency, results in prolonged ST segment and QT interval while hypercalcemia, usually seen with hyperparathy- roidism, results in shortening of both intervals.

E-mail: [email protected] Cerebral salt wasting is a diagnosis of exclusion that requires a natriuresis in a patient with a contracted effective arterial blood volume and the absence of another cause for this excretion of Na+ . Background: The reported prevalence of cerebral salt wasting has increased in the past three decades. A cerebral lesion and a large natriuresis without a known stimulus to excrete so much sodium (Na+ ) constitute its essential two elements. Objectives: To review the topic of cerebral salt wasting. There is a diagnostic problem because it is difficult to confirm that a stimulus for the renal excretion of Na+ is absent.

  • Toxicity Associated with Carbon Monoxide Louise W
    Clin Lab Med 26 (2006) 99–125 Toxicity Associated with Carbon Monoxide Louise W. Kao, MDa,b,*, Kristine A. Nan˜ agas, MDa,b aDepartment of Emergency Medicine, Indiana University School of Medicine, Indianapolis, IN, USA bMedical Toxicology of Indiana, Indiana Poison Center, Indianapolis, IN, USA Carbon monoxide (CO) has been called a ‘‘great mimicker.’’ The clinical presentations associated with CO toxicity may be diverse and nonspecific, including syncope, new-onset seizure, flu-like illness, headache, and chest pain. Unrecognized CO exposure may lead to significant morbidity and mortality. Even when the diagnosis is certain, appropriate therapy is widely debated. Epidemiology and sources CO is a colorless, odorless, nonirritating gas produced primarily by incomplete combustion of any carbonaceous fossil fuel. CO is the leading cause of poisoning mortality in the United States [1,2] and may be responsible for more than half of all fatal poisonings worldwide [3].An estimated 5000 to 6000 people die in the United States each year as a result of CO exposure [2]. From 1968 to 1998, the Centers for Disease Control reported that non–fire-related CO poisoning caused or contributed to 116,703 deaths, 70.6% of which were due to motor vehicle exhaust and 29% of which were unintentional [4]. Although most accidental deaths are due to house fires and automobile exhaust, consumer products such as indoor heaters and stoves contribute to approximately 180 to 200 annual deaths [5]. Unintentional deaths peak in the winter months, when heating systems are being used and windows are closed [2]. Portions of this article were previously published in Holstege CP, Rusyniak DE: Medical Toxicology.
