Pain is a sensation that warns of potential injury and alerts the person to avoid or treat it. For example, if you touch a hot object, you will feel pain and immediately remove your hand from that object, protecting your hand from further damage. As much as pain can burden and torment, ultimately it is an essential part of our bodies’ mechanisms of self-preservation. Pain can be mild or severe, constant or intermittent, sharp or dull. Sometimes it can even be hard to describe the uncomfortable sensation in words. Nevertheless, clinicians always ask their patients to describe their pain. Why? Because its characteristics can help us better determine the mechanism behind a patient’s pain. In the clinic, the patient’s subjective experience of pain can be crucial to arriving at the correct diagnosis and treatment. For this reason, understanding the different kinds of pain and their underlying biology is an essential building block of foundational clinical knowledge. There is no standard system of classifying pain. In this discussion, we will classify the five main types of pain as nociceptive, breakthrough, inflammatory, neuropathic, and functional. After listening to this AudioBrick, you should be able to: Define the different classifications of pain and why they occur. Describe the mechanisms of neuropathic pain. Define and describe transient and chronic paresthesia. Define and describe allodynia and hyperalgesia.

As we eat, our gastrointestinal (GI) system releases a host of both local and distant regulators to control the process of digestion. We will begin with the primary hormones, then cover some of the secondary hormones, and lastly discuss how our body senses its intraluminal contents and then subsequently integrates all of the various stimuli it receives. After listening to this AudioBrick, you should be able to: Identify the location, cell type, release stimulus to the endocrine cells, and function of the major gastrointestinal (GI) hormones secretin, cholecystokinin (CCK), gastrin, vasoactive intestinal polypeptide (VIP). Describe in brief the release stimulus and function of the GI regulatory peptides bombesin, GLP-1, GLP-2, ghrelin, leptin, motilin, somatostatin, and gastric inhibitory polypeptide (GIP). Understand how the physical and chemical compositions of luminal contents are sensed and the hormonal responses that then occur. Outline how GI cells integrate multiple regulatory inputs from hormonal and neural inputs to control function.

Headaches are an unavoidable fact of life and often are nothing more than the result of sitting through one too many lectures. However, they can become debilitating and get in the way of daily life, especially when they become recurrent. Although some headaches have symptoms other than head pain, we typically think of headache pain relative to its location, how intense it is, and how long it lasts. After listening to this AudioBrick, you should be able to: Compare and contrast the clinical features of primary headache syndromes (migraine, cluster, tension-type headaches). Differentiate migraine aura from other transient neurological disorders (eg, transient ischemic attacks, seizure, presyncope). Discuss the mechanisms of central nervous system sensitization and pain referral and the interaction of neural structures, particularly pain pathways and neurovascular control. Outline which patients warrant radiologic or other lab evaluation for headache. Describe the treatment of patients with headache disorders and potential complications of treatment.

he ductus arteriosus (DA) is a structure that allows blood pumped from the right side of the heart to bypass the lungs while the fetus is developing in utero. Normally, the DA closes shortly after birth and becomes the ligamentum arteriosum. When the DA fails to close (remains open, or patent) after birth, it is known as patent ductus arteriosus (PDA). This acyanotic congenital heart defect causes abnormal blood flow from the left to the right side of the heart and can lead to heart failure and failure to thrive in neonates. After listening to this AudioBrick, you should be able to: Define patent ductus arteriosus (PDA). Describe the anatomy and intrauterine function of the ductus arteriosus, the normal sequence of changes in the ductus during the transition from fetal to postnatal circulation, and the consequences of failure to close the ductus. Describe the findings on physical exam of an infant with a PDA, the clinical presentation of a child with a significant PDA, and the diagnostic tests used to confirm the diagnosis of PDA. Explain the treatment options for a child with a PDA, along with the risks and complications associated with an untreated PDA.

Substance use disorder (SUD) refers to a pattern of substance use—be it nicotine, cannabis, cocaine, or something else—that causes significant impairment or distress to the user. SUD is prevalent and growing in the United States and around the world. People of any age may be at risk for developing a substance use disorder. But exposure to and experimentation with alcohol and drugs usually begins in early adolescence. Many adolescents experiment with substances and then taper down or stop using them. Others continue to advance their drug use, leading to a diagnosable substance use disorder with negative health and social consequences. The Diagnostic and Statistical Manual of Mental Disorders (fifth edition; DSM-5) is the widely accepted and respected guide to diagnosing psychiatric disorders in the United States. Substance abuse has been recognized in the DSM-5 as a mental health disorder for many years. The manual no longer describes substance abuse and dependence separately but instead globally uses substance use disorder with specifiers to determine the severity of the use. After listening to this AudioBrick, you should be able to: Define and explain the essential features of substance use disorders. Describe the epidemiology of substance use disorders. Explain how the reward pathway in the brain is involved in the development of substance use disorders, and describe how the brain changes during active use and recovery. Describe the evidence-based assessments and treatment approaches for substance use disorders.

Stimulant medications are drugs that increase alertness and attention. They also elevate heart rate, blood pressure, and respiratory rate. Stimulants are used to treat many conditions, including attention-deficit/hyperactivity disorder (ADHD), chronic lethargy, narcolepsy, and obesity. Examples of stimulants include caffeine, amphetamines (such as dextroamphetamine), methylphenidate, and modafinil. Cognitive-enhancing drugs serve a similar purpose, increasing memory, alertness, and attention. These drugs are used to treat Alzheimer disease, Lewy body dementia, and other neurocognitive disorders. After listening to this AudioBrick, you should be able to: Name conditions for which stimulants and cognitive-enhancing drugs are used as treatment. Describe the mechanism of action of stimulants and cognitive-enhancing drugs. List the main examples of stimulants and cognitive-enhancing drugs. Describe the significant adverse effects of stimulants and cognitive-enhancing drugs.

If you’ve studied the hematopoietic system malignancies—all the leukemias, lymphomas, and plasma cell disorders—you probably feel like you’ve been hit with the good old medical school fire hose. Now’s a good time to take a step back from all the details, make sure that you remember the underlying framework, and pull together some information that connects several different diseases. In this brick, we’ll revisit some of the hematopoietic diseases that we often talk about in pairs: acute vs chronic leukemias, benign lymph node diseases vs lymphoma, and low-grade vs high-grade lymphomas. Also, in case you haven’t already done this on your own, we’ll pull together all the important translocations, their respective diseases, and the reasons why we should remember them. After listening to this AudioBrick, you should be able to: Compare and contrast acute and chronic leukemias. Compare and contrast the morphologic features of benign follicular hyperplasia and follicular lymphoma. Compare and contrast the morphologic and clinical features of low-grade and high-grade lymphomas and give examples of each. Know the following translocations and name the disease (and prognostic significance, if any) associated with each: t(8;21), t(15;17), inv(16), 11q23, FLT3 mutation, t(9;22), t(11;14), t(14;18), and t(8;14).

Megaloblast. Now there’s a word you don’t hear every day. The root -blast (from the Greek blastos, meaning germ or bud) may be somewhat familiar since we talk about blast cells (very young hematopoietic precursor cells) in hematology. And megalo- (from the Greek megas, meaning large or great) is also used fairly frequently, as in splenomegaly (enlargement of the spleen). So does “megaloblast” just mean a large, immature cell? We’ll answer this question, and many more, in this discussion of megaloblastic anemia. After listening to this AudioBrick, you should be able to: Describe the pathogenesis of megaloblastic anemia. List common causes of B12 and folate deficiency and associated nonhematologic symptoms of each. List and understand the characteristic complete blood count values in megaloblastic anemia. Describe and identify the morphologic changes present in the blood and bone marrow in a patient with megaloblastic anemia. Describe the treatment of megaloblastic anemia.

Blood glucose is proof that you can have too much of a good thing. While glucose serves a critical role as fuel for many of our bodily functions, it must remain in a very tightly controlled range. If the level goes too low, you can fall into a coma. If glucose is too high, damage to tissues throughout the body can occur. When blood glucose is consistently too high and the mechanisms that return it to the normal range fail, this is called diabetes mellitus. Nearly 10% of the US population has a form of diabetes, so it is critical that physicians understand the disease and be prepared to care for patients with the diagnosis. Diabetes mellitus is a condition characterized by a lack of insulin-mediated blood glucose control. Insulin is a hormone released by the pancreatic β cells in the islets of Langerhans, which make up the endocrine portion of the pancreas. After listening to this AudioBrick, you should be able to: Define type 1 and type 2 diabetes mellitus. Compare and contrast the pathophysiology of type 1 and type 2 diabetes mellitus. Compare and contrast the clinical presentation of type 1 and type 2 diabetes mellitus. Compare and contrast diabetic ketoacidosis and hyperglycemic hyperosmolar nonketotic syndrome as complications of diabetes mellitus.

Gallstones are the hardened precipitates—“stones”—of the substrates found in bile. The liver makes bile to help digest fats, and the bile is stored in the gallbladder. When there is an excess of a particular substance in the bile (eg, cholesterol or unconjugated bilirubin), gallstones form in the gallbladder. Gallstones can be as small as a grain of sand, as large as a golf ball, or any size in between. Gallstones are very common and usually do not cause any symptoms. But not all gallstones stay in the gallbladder. After listening to this AudioBrick, you should be able to: Define, compare, and contrast cholelithiasis, cholangitis, choledocholithiasis, and cholecystitis, listing the most common causes of each. Describe the structure and pathogenesis of cholesterol and pigment gallstones. List the major risk factors for development of gallstones, describe the typical clinical course, and list the potential complications. Distinguish acute and chronic cholecystitis, and describe the clinical presentation, signs, and lab abnormalities. Describe the treatment of gallstones and acute cholecystitis.

Normal blood pressure keeps us alive. It’s the force that moves blood throughout our circulatory system, ensuring that oxygen and nutrients reach our organs and tissues and that waste products are eliminated. When we hear the word hypertension—high blood pressure—we know this describes the blood flow exerting too much force against blood vessel walls. Pulmonary hypertension describes high blood pressure in the vessels of the lung. Specifically, pulmonary hypertension is an elevated mean arterial pressure (≥20 mm Hg at rest) of the vessels between the heart and the lung. After listening to this AudioBrick, you should be able to: Define pulmonary hypertension and compare with pulmonary arterial hypertension. Describe the clinical presentation and diagnosis of pulmonary hypertension, including results from electrocardiogram, echocardiogram, and heart catheterization. Explain how pulmonary hypertension leads to right-sided heart failure. Describe how pulmonary vascular resistance affects pulmonary arterial pressure. List common etiologies of pulmonary hypertension, differentiating between cardiac and pulmonary causes. List the most common cause of pulmonary arterial hypertension.

Macroscopic Skin Lesions A thorough skin examination should be performed annually to assess for new or changing macroscopic skin lesions. It is critically important to be able to identify and describe normal and abnormal skin and to note your findings carefully, because a change in an existing skin lesion is the most common sign of skin cancer, including deadly ones like melanoma. In this discussion, we will describe the specific ways in which you document skin lesions, using a vocabulary that other clinicians will understand. After listening to this AudioBrick, you should be able to: Explain the importance of physical examination of the skin. Describe skin lesions, explaining and illustrating each of the following: size, type (eg, vesicle, bulla), color, configuration (eg, annular, targetoid, discoid), arrangement (eg, solitary, grouped, linear, reticular), and distribution and location.

Have you ever cut your finger, bumped your head, or fallen and scraped your knee? While you were cursing your clumsiness or bad luck, your body got straight to work healing the injury, relying on the wondrous process of acute inflammation. Shortly after your injury, you most likely experienced some or all of the cardinal signs of acute inflammation: pain (dolor), redness (rubor), heat (calor), and swelling (tumor). There are two types of inflammation: acute and chronic. Acute inflammation is an essential part of the body’s defense system and generally lasts a few days. Chronic inflammation (discussed in detail in another brick) involves an ongoing low-level inflammation that lasts for weeks, months, or even years. Unlike acute inflammation, chronic inflammation is not beneficial; it leads to tissue damage and is linked to the development of many types of chronic disease, including diabetes, cancer, and a range of autoimmune disorders. After listening to this AudioBrick, you should be able to: Describe the three roles of inflammation. Identify the cells of innate immunity involved in acute inflammation and the timeline of when each cell type is involved. Describe the four reactions of blood vessels in acute inflammation. Describe leukocyte recruitment to sites of inflammation. Explain how these processes result in the general clinical manifestations of acute inflammation. Provide specific examples of acute inflammation. Describe the utility of acute-phase reactants as a marker of inflammation: erythrocyte sedimentation rate, C-reactive protein, ferritin, fibrinogen (all increased with inflammation—positive markers). You can also check out the original brick on Acute Inflammation from our General Pathology collection, which is available for free.

Multiple endocrine neoplasias are familial syndromes of endocrine tumors occurring in endocrine organs throughout the body. Despite its acronym, the risk for acquiring MEN is about the same in men and women and also across geographic and racial and ethnic groups. These are rare syndromes, affecting about 1 in 30,000 people. Genetic mutations cause the MEN syndromes, which are then inherited in an autosomal dominant pattern. This means several members of the same family are often affected; an affected parent has a 50% chance of passing down the disease to his or her children. Unlike cancers without a hereditary basis, tumors associated with MEN often occur in younger patients (under age 40 years) and affect multiple organ systems all at once, making them particularly troublesome. Generally, tumors may arise in the pituitary gland, parathyroid glands, thymus, pancreas, thyroid, or adrenal glands (Figure 1). The three major types of multiple endocrine neoplasia are MEN1, MEN2A, and MEN2B, and each has a characteristic picture of endocrine or neurologic disorders and tumors. After listening to this AudioBrick, you should be able to: Define multiple endocrine neoplasia (MEN), and list the three MEN syndromes. Compare and contrast the main clinical features of MEN1, MEN2A, and MEN2B. Describe the genetic defects that cause MEN1, MEN2A, and MEN2B. Briefly describe the management of the MEN syndromes.

Myocarditis is the inflammation of the heart muscle. This muscle is the middle layer of the heart, formally called the myocardium, hence the name myocarditis (the -itis suffix indicates inflammation). Inflammation of the myocardium can be caused by a variety of etiologies, from infection to drugs. If severe enough, inflammation can lead to necrosis and cardiomyocyte death. This is dangerous because the heart is considered permanent tissue. This means there is limited regenerative potential, so tissue loss is essentially permanent. As part of the healing process, myocardial tissue is replaced by a fibrous scar to fill the defect. But because the fibrous scar has no contractile properties, it diminishes the heart’s strength. If severe enough, this damage can even cause heart failure. After listening to this AudioBrick, you should be able to: Define myocarditis. List the most common viral, bacterial, fungal, and parasitic causes of myocarditis, and describe the general mechanism for how these agents damage the myocardium. List noninfectious causes of myocarditis, and describe the general mechanism for how the myocardium is damaged in these conditions. Describe the characteristic microscopic features of acute infectious myocarditis. Describe the typical presentation, clinical spectrum, and prognosis of myocarditis.

Learning is traditionally defined as acquiring knowledge through study, experience, or being taught. In psychology, it is often defined as a relatively lasting change in behavior that results from experience. Learning is an ongoing process; we continue learning throughout our entire lives. After listening to this AudioBrick, you should be able to: Name and briefly describe the three major theories of learning. Define classical conditioning, including unconditioned stimulus, unconditioned response, neutral stimulus, conditioned stimulus, and conditioned response. Define operant conditioning and differentiate between positive reinforcement, negative reinforcement, positive punishment, and negative punishment. Compare and contrast classical and operant conditioning. Describe examples of social learning theory.

Salmonella and Shigella species are almost made to be confused—two bacterial infections in the Enterobacteriaceae family that are spread by food and dirty conditions, cause gastroenteritis, and start with S! To make matters more confusing, they look similar on microscopy. While they are more common in developing communities, they are also seen in the United States. Here, we will give you the tools to keep these bugs and their presentations straight. After listening to this AudioBrick, you should be able to: Differentiate the microscopic and growth characteristics and habitat of Salmonella typhi, Salmonella spp other than S typhi, and Shigella. Describe the host (risk) factors, mode of transmission, and pathobiology of diseases caused by these organisms. Describe the clinical manifestations of diseases caused by these organisms. Discuss concerns of antibiotic resistance related to these organisms.

he ductus arteriosus (DA) is a structure that allows blood pumped from the right side of the heart to bypass the lungs while the fetus is developing in utero. Normally, the DA closes shortly after birth and becomes the ligamentum arteriosum. When the DA fails to close (remains open, or patent) after birth, it is known as patent ductus arteriosus (PDA). This acyanotic congenital heart defect causes abnormal blood flow from the left to the right side of the heart and can lead to heart failure and failure to thrive in neonates. After listening to this AudioBrick, you should be able to: Define patent ductus arteriosus (PDA).

You probably know that the kidneys play an important role in maintaining blood pressure within the normal range. You might also know that they do this by regulating blood volume and the degree of arterial contraction or dilation (the systemic vascular resistance). But do you know how the kidneys do this? The answer is the kidneys accomplish this primarily through a set of hormones and enzymes known together as the renin-angiotensin-aldosterone system (RAAS). In this brick, we will discuss the components, functions, and regulation of the RAAS. Renin is an enzyme released by the kidneys that ultimately causes the formation of the hormone angiotensin II (Ang II) in the body—which in turn stimulates the release of the hormone aldosterone from the adrenal cortex. Ang II and aldosterone act in a number of ways to increase blood volume and blood pressure. RAAS acts to increase sodium reabsorption in the kidney, increase vascular tone, and even stimulate antidiuretic hormone (ADH) to reabsorb more water: all of these defend our extracellular volume and blood pressure. RAAS is therefore a critical system for keeping us upright! After listening to this Audio Brick, you should be able to: Outline the renin-angiotensin-aldosterone system, including sensors, factors that control it, sources of hormone release, and the actions of each hormone. Describe the mechanisms by which the renin-angiotensin-aldosterone system regulates blood pressure. Compare and contrast tubuloglomerular feedback with the renin-angiotensin-aldosterone system.

Hemophilia is a bleeding disorder resulting from defects in factors of the coagulation cascade. There are two primary types of hemophilia: A and B. Both types of hemophilia are rare, with only a combined frequency of about 1 in 5000 live births. Of the two types, hemophilia A is about four times more common. In the intrinsic arm of the coagulation cascade, factor VIII serves as a cofactor for factor IX. They cooperate to activate factor X, leading to the formation of fibrin. After listening to this AudioBrick, you should be able to: Compare and contrast the underlying defect in hemophilia A and B. Describe the inheritance pattern and relative incidence of hemophilia A and B. Describe the clinical features of hemophilia A and B. Explain how hemophilia A and B are diagnosed.

Mitral stenosis (MS) is a narrowing of the mitral valve. In the normal cardiac cycle, the heart relaxes during diastole and allows blood to flow from the left atrium to the left ventricle through the open mitral valve. When the mitral valve is narrowed, blood flow becomes restricted (Figure 1). Excess volume and pressure build up in the left atrium, while forward flow to the left ventricle decreases. After listening to this AudioBrick, you should be able to: Define mitral stenosis. List and explain the common causes of mitral stenosis. Describe the clinical presentation and diagnosis of mitral stenosis. Describe the treatment of mitral stenosis.

Social determinants of health are the nonmedical factors that influence health outcomes, many times in ways that we may not be even aware of. Even though we often consider the medical risk factors that affect the health of individuals, we can ignore the role that social and environmental factors, such as housing conditions and access to healthcare and education, can play. In this episode, we present the podcast version of the Social Determinants of Health brick developed by MeSAGE, the Medical Student Alliance for Global Education, and explore the ways in which social determinants impact health outcomes. We discuss how factors such as income, education levels, access to healthcare, and living conditions all affect the overall health of an individual or a population. We also explain the importance of recognizing these social determinants in order to develop successful interventions that improve health outcomes. This is just one of the free and open Bricks that MeSAGE developed for the Diversity, Equity, and Inclusion collection.  Through this collection, we aim to generate awareness and provide support for health care students and educators to learn more about cultural competency and social determinants of health. We hope that these resources will help provide a foundation for educators, students, and healthcare providers to better understand how social determinants can influence the health outcomes of their patients and communities.

Aortic stenosis (AS) is a condition in which there is a narrow left ventricular outflow tract caused by failure of the aortic valve to open up completely. The heart has to work harder to pump blood through this tight opening to deliver blood to the rest of the body. The aortic valve is positioned between the left ventricle and the aorta, the main artery that leaves the heart and supplies blood to the rest of the body. The valve is usually made up of three leaflets and is called a semilunar (SL) valve because of the half-moon–shaped leaflets. Semilunar valves (aortic and pulmonic) are positioned between a ventricle and a great vessel (as opposed to an atrioventricular valve between an atrium and a ventricle). When the left ventricle contracts (this is called systole), the leaflets of the aortic valve open and let blood flow out of the left ventricle and into the rest of the body. In AS, the valve leaflets do not open up completely, thus reducing blood flow in systole. After listening to this Audio Brick, you should be able to: Define aortic stenosis (AS). List and explain the common causes of AS. Describe the common signs and symptoms in patients with AS, and explain why these findings occur. Explain how to diagnose AS. List the treatment options for AS. Describe the indications for valve replacement. You can also check out the original brick from our Cardiology collection, which is available for free.

Gastrulation is a major milestone in development. It is the process of forming a trilaminar (three-layered) embryo by creating the three germ layers (ectoderm, mesoderm, endoderm). These germ layers are the building blocks for forming the entire body. The term gastrulation means formation of the gastrula, which is the name of the three-layered embryo. Gastrulation takes place during week 3 of development. (Remember: week 3 = 3 layers.) But before we get to the nitty gritty of gastrulation, let’s back up and review what happens in week 2 of development that sets the stage for this important process. After listening to this Audio Brick, you should be able to: Define the term gastrulation, know when it occurs, and describe the process of forming the three germ layers and their orientation to each other. Describe the development and fates of ectoderm derivatives including surface ectoderm, neural tube, and neural crest and list the adult tissues that are derived from ectoderm. Describe the development and fates of each region of mesoderm, including paraxial, intermediate, and lateral, and list the adult tissues that are derived from mesoderm. Describe the development and fate of endoderm and list the adult tissues that are derived from endoderm.

When you know the meaning of the word autonomic, the role of the autonomic nervous system (ANS) becomes clearer. Autonomic denotes involuntary or subconscious activity. In physiology, it refers to the many bodily functions that are subconsciously controlled, such as breathing, digestion, and—most relevant to our discussion here—heartbeats. The ANS is the neural network that controls these subconscious functions. For variable control, there are two opposing divisions of the ANS: The sympathetic nervous system (SNS) controls many functions under times of acute stress. Its effects are generally described as a “fight-or-flight” response because it’s sympathetic to our plight. The parasympathetic nervous system (PSNS) controls many of these same functions when the SNS is not activated. It produces the default setting so to speak. It is often described as a “rest-and-digest” response. Anatomically speaking, the SNS and PSNS have separate divisions; the SNS is derived from the thoracolumbar division while the PSNS is derived from the craniosacral division. After listening to this Audio Brick, you should be able to: Define the autonomic nervous system (ANS). Identify which ANS component is dominant at rest and during exercise. Describe cardiac innervation. Describe the mechanisms by which the ANS alters ion conductance and subsequently the action potentials to ultimately modulate heart rate and contractility.

Aneuploidies are chromosome number abnormalities. Trisomies fall under the umbrella of aneuploidies. The term trisomy comes from tri, meaning tripled, and soma, meaning body—the tripling of a single chromosomal body. This serious genetic abnormality can have significant effects on development. There are two types of trisomies: X/Y and autosomal. The X/Y trisomies result from an extra copy of one of the sex chromosomes. They include conditions like Klinefelter syndrome (47, XXY) and triple X syndrome (47, XXX). Autosomal trisomies result from an extra copy of one of the 22 autosomal (nonsex) chromosomes and include several conditions we will discuss in more detail below. Trisomies can result from abnormal chromosome separation during meiosis or from an inherited joined chromosome. The most common type of joined chromosome is called a Robertsonian translocation and can lead to trisomies in offspring. Most trisomies are embryonic lethal abnormalities. Only trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome), and trisomy 13 (Patau syndrome) are survivable until birth, and generally only trisomy 21 individuals survive infancy. After listening to this Audio Brick, you should be able to: Explain how a carrier of a Robertsonian translocation is at higher risk of having a child with a trisomy. Contrast the genetic etiology and clinical presentation of Down syndrome, Edwards syndrome, and Patau syndrome. Differentiate Down syndrome, Edwards syndrome, and Patau syndrome based on ultrasonographic findings and altered serum marker levels.

Glucose is the main source of energy for all forms of life, but it isn’t usually stored as individual C6H12O6 molecules. Animals use glycogen to do that job. Glycogen is a large branched polymer of glucose molecules, linked together by α-1,4 and α-1,6 glycosidic bonds. The liver and muscles break down the stored glycogen whenever the body needs an extra boost of glucose. Glycogen storage diseases are genetic defects in glycogen metabolism resulting in accumulation of glycogen. What happens when macromolecules accumulate in cells? Cell damage and dysfunction. Because the liver and muscles are the two main organs that use glycogen, they are also the two most affected by glycogen storage diseases. In the liver, glycogen accumulation leads to hypoglycemia since the glycogen can’t be broken down to glucose. Damage to the liver from extra glycogen can also lead to liver failure or even liver cancers. In the muscles, glycogen accumulation causes weakness, exercise intolerance, and potentially heart failure. There are at least 12 distinct glycogen storage diseases, but we’ll cover only the 4 most common ones. After listening to this Audio Brick, you should be able to: Identify the most common glycogen storage diseases: von Gierke disease (type 1), Pompe disease (type 2), Cori disease (type 3), and McArdle disease (type 5). Identify the enzymes deficient in each of the most common glycogen storage diseases. Describe the clinical manifestations of each of the most common glycogen storage diseases. Describe management for each of the most common glycogen storage diseases. You can also check out the original brick from our Cellular and Molecular Biology collection, which is available for free.

Cardiac auscultation is a clinical skill that involves listening to heart sounds using a stethoscope. It is a low-tech way of detecting disease directly without expensive scanners, blood work, or pathology reports—and another reminder that the art of medicine is not a lost art despite today’s technology. Moreover, heart disease is so common that we see plenty of it in many different specialties. Before we get into pathologic sounds, though, we need to learn the basics of normal heart sounds. After listening to this Audio Brick, you should be able to: Explain how hemodynamic and electrocardiogram (ECG) events correlate with normal S1 and S2 heart sounds. Explain the physiology of normal S2 splitting. Explain the physiology and causes of the following types of abnormal S2 splitting: wide splitting, fixed splitting, and reversed splitting (paradoxical splitting). Define the extra S3 and S4 heart sounds and describe their timing, physiology, and clinical significance.

Eukaryotic cells reproduce themselves by going through the cell cycle, which divides one cell into two. The cell cycle comprises two main phases, interphase and mitosis, both of which are further broken down into steps, as well as a separate resting phase. When a cell divides appropriately, this allows our bodies to fix damaged tissue and replace old layers of cells. However, when the cell cycle happens either at an inappropriate time or without stopping, cancers can develop. This is why the cell cycle is highly regulated with multiple checkpoints and myriad regulatory proteins. Next, we’ll go over the steps of the cell cycle and dive into the complex regulatory mechanisms that prevent cancers from forming. After listening to this Audio Brick, you should be able to: Outline the four main stages of the cell cycle. Describe the role of cyclins and cyclin-dependent kinases in promoting cell cycle progression. Describe the cell cycle checkpoints. Outline the process of mitosis.

Hyperthyroidism is an elevation in the serum thyroid hormones T3 and T4 (thyroxine), caused by excess thyroid hormone production from the thyroid gland. This can result from an abnormal thyroid gland (primary hyperthyroidism) or increased synthesis of thyroid stimulating hormone (TSH) by the anterior pituitary gland (secondary hyperthyroidism) or by overdosing on thyroid medication (exogenous hyperthyroidism). The latter is common because thyroid hormone is an effective agent for losing weight, since it increases the basal metabolic rate. Although less common than other endocrine disorders like diabetes and Cushing syndrome, hyperthyroidism is one of the most dramatic presentations you will see in all of clinical medicine, with its bulging eyes and goiter, sweatiness, and hyperactivity. Let’s discuss its causes, diagnosis, and management. After listening to this Audio Brick, you should be able to: Define hyperthyroidism and describe its typical clinical features. Explain the common causes of primary, secondary, and exogenous hyperthyroidism. Describe the pathogenesis and histologic features of Graves disease and toxic multinodular goiter, and describe their unique clinical findings. Describe the diagnosis of hyperthyroidism. Outline the basic management of hyperthyroidism. You can also check out the original brick from our Endocrine collection, which is available for free.

You probably know that the kidneys play an important role in maintaining blood pressure within the normal range. You might also know that they do this by regulating blood volume and the degree of arterial contraction or dilation (the systemic vascular resistance). But do you know how the kidneys do this? The answer is the kidneys accomplish this primarily through a set of hormones and enzymes known together as the renin-angiotensin-aldosterone system (RAAS). In this brick, we will discuss the components, functions, and regulation of the RAAS. Renin is an enzyme released by the kidneys that ultimately causes the formation of the hormone angiotensin II (Ang II) in the body—which in turn stimulates the release of the hormone aldosterone from the adrenal cortex. Ang II and aldosterone act in a number of ways to increase blood volume and blood pressure. RAAS acts to increase sodium reabsorption in the kidney, increase vascular tone, and even stimulate antidiuretic hormone (ADH) to reabsorb more water: all of these defend our extracellular volume and blood pressure. RAAS is therefore a critical system for keeping us upright! After listening to this Audio Brick, you should be able to: Outline the renin-angiotensin-aldosterone system, including sensors, factors that control it, sources of hormone release, and the actions of each hormone. Describe the mechanisms by which the renin-angiotensin-aldosterone system regulates blood pressure. Compare and contrast tubuloglomerular feedback with the renin-angiotensin-aldosterone system.

Glycolysis is the first step of metabolism and the biochemical pathway by which glucose is converted into pyruvate. Some cells use glycolysis to make pyruvate to use in other metabolic processes; others, like erythrocytes, rely on glycolysis as their main means of energy production. Because glycolysis is central to energy production, it is tightly regulated by many mechanisms. Metabolites along the glycolytic pathway also regulate other processes in the body. Figure 1 shows the overall pathway of glycolysis with all its intermediates, enzymes, and cofactors. It looks daunting, but don’t worry! We’ll break down all the important components and go through it step by step. After listening to this Audio Brick, you should be able to: Describe the reactions of glycolysis in sequence and know where ATP (adenosine triphosphate) is used and where ATP is made. Identify the reactions that are rate-limiting in the pathway. Explain the regulation of the pathway with emphasis on the rate-limiting reactions. Describe the roles of insulin and glucagon in the regulation of glycolysis and the enzyme targets. Explain why glycolysis occurs in all cells, including erythrocytes, and explain the relevance of oxygen availability and mitochondria in terms of the end products of glycolysis. Explain 2,3-bisphosphoglycerate and its relevance to glycolysis and the binding of oxygen to hemoglobin. Identify the diseases associated with defects in glycolysis, particularly pyruvate kinase defect. You can also check out the original brick from our Endocrine collection, which is available for free.

People who play tennis or golf, or even those who get wrist or shoulder pain from working on their computers, likely are familiar with pain around the joints of the upper extremity. Is it rotator cuff tendonitis or subacromial bursitis? Tennis elbow or olecranon bursitis? Similar conditions can affect the lower extremity: jumper’s knee or popliteal bursitis? Because bursae are located in direct proximity to tendons, inflammation of one can mimic that of the other, causing nearly identical pain in the same parts of the body. How do you determine the culprit? Tendonitis is an inflammation or irritation affecting the tendon; bursitis refers to an inflammation or irritation affecting the joint bursae. In this discussion, we explain common types of tendonitis and bursitis, differentiating them as we go. After listening to this Audio Brick, you should be able to: Define tendonitis and bursitis and compare their epidemiology and causes. Describe two common forms of tendonitis, rotator cuff tendonitis and lateral epicondylitis, and discuss their clinical presentations, diagnosis, and treatments. Describe three common forms of bursitis, shoulder bursitis, olecranon bursitis, and popliteal (Baker) cysts, and discuss their clinical presentations, diagnosis, and treatment.

*** Rx Bricks Season Pass https://go.usmle-rx.com/brick-season-pass/ *** Diabetic ketoacidosis (DKA) is one of the most dreaded acute complications of diabetes mellitus. It is a medical emergency. When patients with DKA arrive at the emergency department, they are clearly ill, with vomiting, diarrhea, disordered breathing, and mental status changes—even unconsciousness. Up to 2% of patients with DKA may die from the disorder. This means physicians must understand the multistep and complex treatment. Let’s look at what is involved. After listening to this Audio Brick, you should be able to: Define diabetic ketoacidosis (DKA) and present an overview of the risk factors for DKA. Describe the pathophysiology of DKA. Describe the presenting signs and symptoms of DKA, and explain how they relate to the pathophysiology. Discuss common laboratory findings at presentation and during treatment of DKA.

*** Rx Bricks Season Pass https://go.usmle-rx.com/brick-season-pass/ ***   Some of the most dreaded chronic complications of diabetes mellitus come from injury to the blood vessels. Such injury may lead to blindness, renal failure requiring dialysis, and early death from heart attacks. These complications develop slowly over years and can be divided into two groups based on the size of the blood vessels involved—microvascular and macrovascular. The good news is that many can be prevented or slowed by excellent control of blood glucose, so there is hope. Let’s examine these complications in detail. After listening to this Audio Brick, you should be able to: Describe the microvascular and macrovascular complications of diabetes mellitus. Explain how elevated blood sugar leads to these complications. Describe screening and prevention strategies for complications of diabetes mellitus.

Cushing syndrome is a cluster of clinical features resulting from exposure to excess glucocorticoids (hypercortisolism). Most of the abnormalities in Cushing syndrome are caused by high levels of cortisol itself, but an accompanying excess of androgens and mineralocorticoids like aldosterone may also add to the syndrome. Cortisol is produced continuously in the adrenal gland. It even has a specific circadian pattern. This means it is at its highest peak in the morning after we wake up from sleep and gradually declines during the day. The lowest concentration is typically in the late evening, before bedtime, with a big decrease around midnight. Levels also vary based on the day’s activities. Cortisol is part of the fight-or-flight response that helps us react to unexpected and frightening circumstances. Produced in the adrenal gland’s zona fasciculata, cortisol does three main things: Increases blood pressure Changes metabolic activity Decreases the inflammatory response Cortisol increases blood pressure by upregulating α1 adrenergic receptors in the arterioles. This increases their sensitivity to norepinephrine and epinephrine, leading to vasoconstriction. Cortisol also increases insulin resistance and facilitates gluconeogenesis, lipolysis, and proteolysis; these changes help the body prepare to battle stressors—or run from them. Furthermore, cortisol modulates the immune response and decreases the body’s inflammatory and immune reactions by a variety of mechanisms. From this perspective, cortisol seems to help us battle external threats, which means its presence in the human body is welcome. However, prolonged secretion and chronic high levels of cortisol causes hypercortisolism (Cushing syndrome), leading to other effects: Decreased fibroblast activity and poor wound healing Decreased osteoblast activity and therefore slower bone formation Reduced immune response and therefore increased infections Chronic increased serum glucose, leading to a secondary form of diabetes You can also check out the original brick from our Endocrine collection, which is available for free.

Getting the air to our lungs in the first place can be challenging enough. How do we get the oxygen out of the air once we have it in our lungs? This huge job comes down to one tiny unit: the alveoli-capillary unit. In this brick, we take a look at how the exchange of gases takes place. After listening to this AudioBrick, you should be able to: Describe the features, dimensions, and components of the respiratory membrane. List the components and explain the function of surfactant. List the factors that affect the rate of gas exchange across the respiratory membrane. Describe the alveolar gas equation and explain how it is used. Define respiratory quotient.

Type 1 diabetes mellitus, previously known as juvenile diabetes, is one of the most common chronic diseases in childhood. The pathophysiology of type 1 diabetes begins with autoimmune destruction of the insulin-producing β cells in the islets of Langerhans, thus leading to insulin deficiency. A crucial role of insulin is to increase glucose uptake into tissues. When insulin is deficient or absent, high blood sugar levels in the body (hyperglycemia) can occur. These have long-term adverse effects. But other metabolic disorders occur as well, including hyperlipidemia and ketonemia (formation of acidic ketone bodies). After listening to this AudioBrick, you should be able to: Define type 1 diabetes mellitus and describe its epidemiology. Describe the underlying pathophysiology of type 1 diabetes mellitus. Describe how type 1 diabetes mellitus presents clinically, and outline common acute and chronic complications. Outline the laboratory testing that confirms the diagnosis of type 1 diabetes mellitus. Briefly describe the management of type 1 diabetes mellitus. You can also check out the original brick from our Endocrine collection, which is available for free.

The ovaries are a pair of reproductive organs located deep in the pelvis of the female body; they contain the female gametes, the ova. As in many other organs, cancerous and benign tumors (neoplasms) can arise there, but most are malignant. Such tumors are distinct from ovarian cysts, although some ovarian neoplasms may have cystic features. Ovarian tumors can originate from many of the cell types found in the ovaries, and the cell of origin has a significant effect on how the tumor behaves. Up to 8% of women will present with ovarian masses in their lifetime. The incidence of ovarian cancer is 13 women per 100,000 per year (compared with breast cancer’s incidence of 124/100,000), and about 22,000 new cases are diagnosed annually in the United States. In malignant form, ovarian tumors are a deadly form of cancer—the most common cause of cancer death from gynecologic malignancy in the United States. After listening to this AudioBrick, you should be able to: Describe the clinical presentation of the most common types of ovarian tumors. List the various types of ovarian tumors and classify them by epithelial, sex cord stromal, germ cell, non-neoplastic, or metastatic. Compare and contrast the clinicopathologic features of the major types of ovarian tumors. Describe the diagnosis and treatment of ovarian tumors, including the use of tumor markers.

The central nervous system (CNS) comprising the brain and spinal cord is an incredibly complex part of the human body, so it is no surprise that sometimes things go awry during development. The various anatomic anomalies that result can be so severe as to be incompatible with life, such as when most or all of the brain fails to develop, a condition known as anencephaly. CNS anomalies are some of the most common congenital anomalies, and they are among the leading causes of infant mortality and fetal loss. These anomalies can involve brain, spinal cord, and meningeal development and position. Although the brain and spinal cord each arise from the neural tube, their development differs. The end result is that the spinal cord is fairly uniform in structure throughout its length, but the brain subdivides into multiple regions, each with its own structure. Accordingly, congenital anomalies of the spinal cord are similar anywhere along its length, but congenital anomalies of the brain are different in different brain regions. We’ll discuss CNS congenital anomalies in terms of those that can involve both brain and spinal cord (neural tube defects [NTDs]), those that involve the cranial parts of the brain (forebrain anomalies), those that involve the caudal parts of the brain (posterior fossa anomalies), and those that involve the spinal cord, as well as congenital hydrocephalus. After listening to this AudioBrick, you should be able to: Describe the main anatomic feature shared by the neural tube defects, and list some of the known etiologies. Compare and contrast the anatomic and clinical features of spina bifida occulta, meningocele, meningomyelocele, and myeloschisis. Describe the mechanisms that lead to defects of the skull. Describe the main mechanism that leads to forebrain abnormalities. Discuss the anatomic and clinical features and treatment of congenital hydrocephalus. Describe the mechanism that leads to defects of the cerebellum and brainstem. Describe the mechanism that leads to defects of the spinal cord, and discuss the anatomic and clinical features of syringomyelia.

A neoplasm is the abnormal growth of new cells, sometimes called a tumor. A variety of tumors can grow in our bones, and luckily more of them are benign (noncancerous) than malignant (cancerous). What causes these tumors? We usually don’t know, though we do know that most malignant bone tumors are secondary, with cancer spreading to the bones from other organs, including the nearby bone marrow. Malignant primary bone tumors (those that start in the bone) are thankfully rare but still are the sixth most common cancer in children and third most common in adolescents. In the United States, about 3000 cases of malignant bone tumors are diagnosed each year and about half of these cases result in death. The terminology of these tumors overlaps quite a bit and can be confusing. We usually equate the prefix sarco- with muscle (sarcomere, sarcolemma, sarcoplasmic reticulum), but the word actually means flesh or tissue, so it is used in the names of a number of bone tumors, many of which were named before the precise tissue types were known. The other terms are easier: osteo is bone and chondro is cartilage. We’ll introduce the three main types of bone neoplasia and then go into more depth on the primary bone tumors. After listening to this AudioBrick, you should be able to: Define primary, hematopoietic, and metastatic bone tumors, and explain which is most common. Describe the pathologic appearance and clinical presentation of the most common benign primary bone tumors: osteochondroma and osteoid osteoma. Describe the pathologic appearance and clinical presentation of the most common malignant primary bone tumors: osteosarcoma, chondrosarcoma, and Ewing sarcoma.
