1. A 21 year-old college student notices that she frequently develops “cold sores” during stressful final exam week. 1. What is the association between stress and the immune system?
The human body has a built in stress response system that usually self regulates. When a threat is perceived the body deploys white blood cells to the area of the body that is under attack (Segerstrom & Miller, 2006). Because of this, less important cellular activities are reduced and the immune system is left vulnerable. When the body perceives a threat there are three phases it goes through. (Story, 2012). The first is the alarm stage, in which the sympathetic nervous system is stimulated and in response deploys the release of catecholamines and cortisol. This stage is known as the fight or flight response (Story, 2012). The body then enters the resistance phase and either adapts or alters activity to become desensitized to the stressor (Story, 2012). If the stressor overwhelms the body it becomes exhausted, which is the last phase. The immune system is suppressed more in times of greater stress (Segerstrom & Miller, 2006). A person’s effort to manage stress, such as smoking and drug use can also suppress the immune system. (Story, 2012).

Outline the Major Diseases of the Respiratory System with Reference to the Pathophysiology.

...Outline the major diseases of the respiratory system with reference to the pathophysiology. Respiratory or lung diseases are the most rapidly diseases expanding worldwide. Health problems of the lungs or airways make it very difficult to breath. They could be lasting a short amount of time like the common cold or for years. Other allergic diseases, which affect the respiratory system. Respiratory diseases are mostly caused by indoor pollutants. The primary function of the respiratory system is to supply the blood with oxygen. When this fails death is not excluded. Lung diseases occur within the lungs. Some lung and respiratory diseases include asthma, pneumonia tuberculosis and lung cancer. Those will be analyzed in the following essay. [1] Asthma or reactive airway disease is a chronic disorder that results in restricted breathing due to inflammation of the bronchi tubes the main air passages in the lungs. Asthma affects 3-5 % of adults and 7 -10 % of children in the USA. Sever asthma attacks can cause approximately 5000 deaths per year. Three changes occur in the lungs of the people with asthma. First inflammation or swelling where the airway becomes inflamed and produce a mucous. Inflammation then leads to constriction of the muscles around the airways causing the airways to become narrow. This narrowing is also referred to as bronchiole spasm. The third change is increased sensitivity of the airways causing the asthma patient to become overly sensitive to animal dander,...

Pathophysiology of Cancer and Renal Failure

...Pathophysiology: Neoplasia and Renal System School of Nursing 1. Cancer Staging Cancer staging describes the severity of a person’s cancer based on the person’s initial tumor, and whether or not the cancer has metastasized (American Cancer Society, 2012, www.cancer.org). Knowledge of the stage is very important in that is can be used to explain prognosis to the patient, and can be used by the doctor and the patient to plan treatment. Staging of cancer is based on knowledge of the way in which cancer progresses in the body. Malignant cells grow and reproduce without any control or order, and they do not die when they should. In most cases the cancer cells will form a mass called a tumor. As the tumor grows it can invade tissues and organs that are close to it. The malignant cells can also break away from the tumor and enter the bloodstream (Lemone, 2004, p. 284). There are five common elements considered in most staging systems: site of the primary tumor, tumor size and number, lymph node involvement, cell type, and the presence or absence of metastasis. A common staging system is called TNM, which stands for Tumor, lymph Nodes, and Metastasis. When staging a number is added to each letter to indicate the size of the primary tumor and the extent of the cancer spread. (Lemone, 2004, p. 284) Infection, immunity and inflammation in cancer patients are all interrelated. They form what could be...

Pathophysiology of a Myocardial Infarction

...For the purpose of this assignment the author will discuss the pathophysiology of a myocardial infarction and will give an in-depth discussion of one central aspect of care and in this assignment the author has chosen the management of anxiety. Due to word restrictions a brief mention will be given to the other aspects of care. Ischaemia is a term which is used to describe the deficiency in blood supply to any part of the body. In ischaemic heart disease there is a deficiency in the blood supply to the heart muscle which can be caused by an obstruction to, or even a narrowing of the coronary arteries. This in turn reduces the supply of nutrients and oxygen to the heart muscle. Without an optimum oxygen supply the heart muscle is unable to function efficiently.(Boersma et al 2003) There are three ways in which an infarction may develop. 1) The narrowing and hardening of arteries is caused by degenerative changes and also the build up of cholesterol and other fatty deposits which occur in the vessel wall. Plaques which then develop and subsequently become ‘calcified or fibrotic’ is through a process known as atherosclerosis. The atherosclerotic plaque slowly builds up in the inner lining of a coronary artery. The presence of the plaques causes the linings of the artery walls to become roughened and this in turn reduces the size of the lumen and eventually occludes it. As circulation slows down there is a strong possibility of thrombus formation. Should a coronary artery......

Pathophysiology of Multiple Sclerosis

...Pathophysiology of Multiple Sclerosis Multiple sclerosis (MS) is a chronic inflammatory autoimmune demyelinating disease of the central nervous system, affecting the brain and spinal cord. MS affects approximately 400,000 people in the United States alone. The onset of MS is usually between 20 and 40 years of age and is more common in women; men may have a more severe progressive course (Luzzio, 2013). Life expectancy is shortened in persons with MS, and the survival rate is linked to disability. Death usually results from secondary complications but can also be due to primary complications unrelated to MS. The occurrence rate of MS is affected by gene-environment interactions in susceptible individuals (Huether & McCance, 2012). Definition of Disorder Multiple sclerosis is a progressive, inflammatory, demyelinating disorder of the central nervous system (CNS), which can affect the peripheral nervous system (PNS) as well. This disorder affects movements, sensation, and bodily functions (National Multiple Sclerosis Society [NMSS], 2012). There are several types of MS, these include: mixed (general), spinal, and cerebellar. General MS affects both the CNS and PNS, while spinal and cerebellar affect the CNS. Causes and Etiological Factors The cause of MS is unknown, but multiple factors act together to trigger or bring about the disease. Some of these causes include: a virus causing demyelization, violent trauma to the head or spinal cord, and or an immune system attack...

Diabetes Pathophysiology

...Diabetes Pathophysiology * The underlying pathophysiologic defect in type 1 diabetes is an autoimmune destruction of pancreatic beta cells. Following this destruction, the individual has an absolute insulin deficiency and no longer produces insulin. Autoimmune beta cell destruction is thought to be triggered by an environmental event, such as a viral infection. Genetically determined susceptibility factors increase the risk of such autoimmune phenomena. * About 90% of diabetic Americans have type 2 diabetes. The prevalence of type 2 diabetes is higher in African Americans, Native Americans, Hispanics, and Pacific Islanders than it is in Caucasians. Most type 2 diabetes patients are overweight, and most are diagnosed as adults. The genetic influence in type 2 diabetes is greater than that seen with type 1. While concordance rates between monozygous twins for type 1 diabetes are about 30 to 50%, the rate is approximately 90% for type 2 diabetes. Although the genetic predisposition to type 2 diabetes is strong, no single genetic defect has been found. In addition to genetic influences, acquired risk factors for type 2 diabetes include obesity, advancing age, and an inactive lifestyle. CLINICAL MANIFESTATION * Type 1 Diabetes: About 5 to 10 percent of those with diabetes have type 1 diabetes. It's an autoimmune disease, meaning the body's own immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas. Patients with type 1 diabetes have......

Fibromyalgia: the Pathophysiology

...Fibromyalgia: The Pathophysiology Abstract The mystery surrounding fibromyalgia has been long and tedious. At first neurology did not want to claim it saying it was a psychiatric problem, then psychiatric said no the pain of the disease gives you depression and anxiety , and they pushed it off to musculoskeletal system. Where ever it starts, for the patient, the pain is real, it’s their perception. It’s not up to us to judge, but up to us to help ease the pain, and hopefully one day find a cure. But first we must understand how it manifests. With no concrete scientific evidence and only theories to date, we can at least see ways to help ease the pain; therapies to help make the patients more active and have a better quality of life. Fibromyalgia: The Pathophysiology Much debate of Fibromyalgia has existed since the first diagnosis. Some people are lead to believe that it replaced Chronic Pain Syndrome and/or Chronic Fatigue Syndrome. Did it, we will examine that here. Depending on who you talk to Fibromyalgia exists, Endocrinology says no and Neurology says yes. Who’s right, which is what we will find out? What we do know; “Fibromyalgia is a chronic musculoskeletal syndrome characterized by widespread joint and muscle pain, fatigue, and tender points” (McCance RN & Huether RN, 2010, p. 1606). If that is Fibromyalgia does that not describe Chronic Pain Syndrome? Well yes and no, Chronic Pain Syndrome usually stays, is always with you all the time, whereas......

Anaphylaxis Pathophysiology and Emergency Response

...Assessment task 1: Written Assessment Anaphylaxis is a respiratory disease that can be both acute and severe. It has a 3% mortality rate within Australia caused from a range of triggers that may or may not be known to the victim. Although anaphylaxis prevalence has increased, death rates have decreased due to understanding of the disease pathophysiology alongside better and faster management of life threatening symptoms (Liew, Williamson & Tang, 2009). This essay will discuss these points in detail as well as the pharmacological actions of adrenaline, the drug used to fight anaphylaxis in a pre-hospital setting. Anaphylaxis is Type 1 hypersensitivity response as it is ‘IgE mediated’. This involves an antigen/antibody response. To develop hypersensitivity a person must first be exposed to the antigen. On the initial exposure, the antigen activates the immune system and a hyper-production of IgE (immunoglobin) antibodies, which are produced by plasma B cells. The IgE antibody is specific to only that antigen and will bind to basophils and mast cells in the blood and blood vessel tissues, remaining inactive until that same antigen is introduced to the body again. Upon secondary exposure to the antigen, many chemical reactions are undertaken at a rapid rate. The antigen binds to IgE resulting in degranulation of basophil and mast cells and release of chemical mediators such as histamine and leukotriene’s (Arnold & Williams, 2011). Histamine especially have a fast......

...Case Study 1 Nichelle Torres Pathophysiology Session 4 Case Study Case 1 (Chapter 14: Concepts of Neurologic Dysfunction & Chapter 15: Alterations in Neurologic Function) J .S. is a 72-year-old woman with a long history of atherosclerosis (hardening of the arteries). One afternoon, her grandson found her sitting in a chair staring blankly into space. She was tilting toward the right, drooling, and had been incontinent of urine. She was able to focus her eyes on him when he spoke to her, but she was unable to verbalize a response. She was transported to the local hospital and diagnosed with cerebrovascular accident (stroke). Discussion Questions : 1.)What questions could be asked of J. S.'s family to help determine the cause of her stroke as thrombotic, embolic, or hemorrhagic (i.e., questions to assess risk factors for each type of stroke)? * The family may be asked if J.S. is a smoker, or if there is a history of hypertension or diabetes. 2.)Based on the scenario described above, which brain hemisphere (left or right) suffered the ischemic damage? What other manifestations of this stroke location would likely be apparent? *Given the information above, the left hemisphere would be affected because a stroke is contra lateral. The fact that she is drooling and incontinent may suggest damage to the brain stem. 3.)What medical therapies might be used to manage this stroke and/or to prevent another one? *...

There are multiple risk factors that precipitate the metabolic process leading to a diagnosis. The following analyses relevant data in relation to pathophysiology, presenting signs, symptoms and underpinning principles of Type One Diabetes Mellitus (T1DM) and Type Two Diabetes Mellitus (T2DM), their prevalence and incidence, metabolic abnormalities and associated risk factors are also examined. Diagnostic criteria is also examined along with advantages and disadvantages of differing testing screen methods and results. The Australian Bureau of Statistics (ABS), Australian Health Survey 2012, reported that in 2011 – 12 the prevalence of all reported diabetes was at 4.0% (875,400 people) and had remained the same as the 2007/’08 period. Of these people 12.4% had T1DM, 85.3% had T2DM while the remaining 2.3% had diabetes of another kind. Tanamas S, et al. (2013) stated that the prevalence of type two diabetes in peoples over the age of 25 years in Australia is 7.4% and that a further 7.4% remain undiagnosed. The dominance of western lifestyles and diets has contributed to a dramatic rise in obesity within the population. It......

...Conclusions This statewide epidemiological study for the years 1995–2009 finds that incidence of appendicitis has increased over time, incidence rates are higher in the summer months, and whites and Hispanics are at a greater risk of appendicitis compared to African Americans or Asians. Hispanics and Asians have higher odds of perfo- ration compared to whites, and patients with Medicare, This study provides important updates on the epidemi- ology of appendicitis, including information on risk factors of appendicitis, risk factors of perforated appendicitis, and an examination of trends in surgical management. How- ever, it is unknown why the incidence of this disease is increasing over time, is higher during the summer months, or varies by race. More research must be done to under- stand the etiology of this common disease in order to identify possible preventative measures.

...hinder the function causing protein and blood loss in the urine, accumulation of waste product because it can no longer filter, which will then lead to edema in the extremities, fatigue, and elevated blood pressure as a result of inflammation is named glomerulonephritis. Glomerulonephritis disease destroys the kidney and the ability to eliminate waste and extra fluids from the body to be excreted. Globally, it is the second most common disease. The cause of the disease, the pathophysiological aspect of glomerulonephritis including inflammatory response, common clinical presentation and manifestation, therapeutic regimen and treatment with diagnosis and further the risk and prevention of the disease will be elaborated. Etiology and Pathophysiology The etiology of the disease is idiopathic and can either be primary or secondary. The primary cause is as a result of an autoimmune disease or the disease occurs by itself and secondary which may be different number of autoimmune disease like diabetes or lupus, metabolic diseases, malignant from tumors, and complicating systemic infection diseases. These diseases can be triggered resulting in immune-mediated injury and exhibit humoral and cellular components. The immune response when the disease is present causing the glomerulus unable to filter waste and toxins in the kidneys. When the inflammatory cells such as lymphocytes and macrophage accumulate and antibody deposition is absence. With humoral immune......

Acute myocardial infarction (MI) occurs when localized myocardial ischaemia causes the development of a defined region of necrosis. MI is most often caused by rupture of an atherosclerotic lesion in a coronary artery. This causes the formation of a thrombus that plugs the artery, stopping it from supplying blood to the region of the heart that it supplies. Role of thrombosis in MI Pivotal studies by DeWood and colleagues showed that coronary thrombosis is the critical event resulting in MI.

Pathophysiology

...body via the aorta and its branches. The aorta is the largest trunk like artery, with a diameter about equal to that of a large garden hose. After delivering the oxygenated and nutrients throughout the body, the used blood returns to the right atrium through two large vessels, the inferior vena cava and the superior vena cava. The inferior vena cava collects blood from the area of the body below the heart. Where the superior vena cava is receives blood from above the heart. Thus, the left ventricle is responsible for pumping oxygenated blood with nutrients throughout the entire body and for bringing the used of blood back to the right atrium. Complete circulation of the cardiovascular system takes about ten to fifteen seconds. IV. Pathophysiology Rheumatic heart disease refers to the cardiac manifestations of rheumatic fever, including pancarditis (myocarditis, pericarditis, and endocarditis) during the early acute phase and chronic valvular disease later. The most destructive effect of rheumatic fever is carditis, which develops in up to 50% of patients. It may affect the endocardium, myocardium, pericardium, or the heart valves. Pricarditis causes a pericardial friction rug and, occationally, pain and effusion. Myocarditis produces characteristic lesions called Aschoff bodies (in the acute stages) and cellular swelling and fragmentation of interstitial collagen, leading to formation of a progressively fibrotic nodule and interstitial scars. Endocarditis causes......

...Pathophysiology Processes & Consequences of Noma Chamberlain College of Nursing NR283: Pathophysiology May 2016, Professor (Name Here) Pathophysiology Processes & Consequences of Noma Noma disease, commonly referred to as cancrum oris, fusospirochetal gangrene, necrotizing ulcerative stomatitis, and stomatitis gangrenosa is a devastating disease that is famously quoted as “the face of poverty”. This rare disease with high prevalence in Sub-Saharan countries is lethal and has been linked to acute and rapid disease progression in persons that are immunocompromised. Evidence based research suggests a high prevalence of the disease is observed in populations experiencing extreme poverty, malnourishment, and exposure to infectious diseases, while living in a continued state of poor hygiene. This gangrenous infection has a microbial origin, often found in the mouth. It is exacerbated by poor hygiene that give rise to the bacterial micro-organisms responsible for aggressive manifestations observed on individuals infected. Etiology of Noma The exact etiology of Noma disease is unknown. However, it is believed to be multifactorial in nature (Ashok, Tarakji, Darwish, Rodrigues , & Altamimi, 2016). The spread of the disease is due to deteriorating sanitation and inadequate nutrition, most common in underdeveloped countries. Noma is an opportunistic infection, which typically show dominance after a weakened immune system is present, preceding multiple risk......
