York University Inflammation (Types, Detection, and Treatments) Author: Dhruv Tayal Course: Immunobiology Date: 31/10/2017 What is Inflammation? Inflammation is crucial in protecting your body from harm in everyday life. It is part of your body's natural response against infections, cell damage, and irritants. This response needs to be regulated as too little or too much of it can be harmful by itself. The common symptoms of inflammation include swelling (that’s sometimes warm to the touch), redness, and joint pain/ stiffness. The lack of inflammation can lead to progressive tissue damage by bacterial and viral infections. It can also lead to a lack of tissue repair following an injury or workout. Too much inflammation or long-lasting inflammation (Chronic inflammation), can lead to a host of diseases, such as hay fever, periodontitis, atherosclerosis, rheumatoid arthritis, and even cancer. In fact, everyday allergies are also caused by unregulated inflammatory responses. What are the types of inflammation? Inflammation can be divided into either acute or chronic. Acute inflammation is your body’s initial immune response which occurs relatively quickly (usually minutes to hours). Most inflammatory responses will fall under this category. Acute inflammation is common following injury, burns, …show more content…
Prostaglandins are formed by the enzymes COX1 or COX2. The prostaglandins produced by COX1 are generally responsible for the maintenance and protection of the gastrointestinal tract, kidneys, and other organs. The prostaglandins produced by COX2 are predominantly known to cause inflammation and pain responses. NSAIDs work by primarily inhibiting the formation of prostaglandins by the COX2 enzyme. As the formation of the prostaglandins produced by COX2 diminishes, pain and inflammation also
The immunologic events that are happening at the local level during Carlton's acute inflammatory response would be:
Sepsis is defined as an exaggerated, overwhelming and uncontrolled systemic inflammatory response to an initially localised infection or tissue injury, which may lead to severe sepsis and septic shock if left untreated (Daniels, 2009; Robson & Daniels, 2013; Dellinger et al, 2013; Perman, Goyal & Gaieski, 2012; Vanzant & Schmelzer, 2011). Septic shock can be classified by acute circulatory failure as a result of massive vasodilation, increased capillary permeability and decreased vascular resistance in the body, causing refractory hypotension despite adequate fluid resuscitation. This leads to irreversible tissue ischaemia, end organ failure and ultimately, death (McClelland & Moxon, 2014; Sagy, Al-Qaqaa & Kim, 2013, Dellinger et al, 2013).
Rheumatoid arthritis is a chronic inflammatory and an autoimmune disease that occurs when the immune system mistakenly attacks the body’s tissue (Rheumatoid arthritis, 2017). This disease affects the entire body, which is called a systemic (means entire body) disease. Arthritis is derived from the word part arthr-, which means “joint,” and -itis, which means “inflammation,” so altogether it means “inflammation of the joints.” It creates inflammation that causes the tissue that lines the inside of joints (synovium) to thicken. About 1.5 million people in the U.S. are affected. It affects all races, but it affects three times as many women than men (What is Rheumatoid Arthritis, n.d.). Overtime, rheumatoid arthritis causes painful swelling that can potentially result in bone erosion or joint deformity, which leads up to physical disabilities. RA can affect more than just your joints, but can spread to body systems, skin, eyes, lungs, heart, blood vessels, e.t.c (Rheumatoid arthritis, 2017).
Chronic bronchitis is a disorder that causes inflammation to the airway, mainly the bronchial tubules. It produces a chronic cough that lasts three consecutive months for more than two successive years (Vijayan,2013). Chronic Bronchitis is a member of the COPD family and is prominently seen in cigarette smokers. Other factors such as air pollutants, Asbestos, and working in coal mines contributes to inflammation. Once the irritant comes in contact with the mucosa of the bronchi it alters the composition causing hyperplasia of the glands and producing excessive sputum (Viayan,2013). Goblet cells also enlarge to contribute to the excessive secretion of sputum. This effects the cilia that carry out the mechanism of trapping foreign bodies to allow it to be expelled in the sputum, which are now damaged by the irritant making it impossible for the person to clear their airway. Since the mechanism of airway clearance is ineffective, the secretion builds up a thickened wall of the bronchioles causing constriction and increasing the work of breathing. The excessive build up of mucous could set up pneumonia. The alveoli are also damaged enabling the macrophages to eliminate bacteria putting the patient at risk for acquiring an infection.
The disease can either be active or in remission depending on whether the tissues are inflamed or not. There are no systems when Rheumatoid Arthritis is in remission. When it becomes active again, it is called a flare and all the symptoms come back. The main symptoms are: fatigue, loss of appetite, fever, aches in the muscles and joints, and stiffness. The stiffness usually occurs in the morning or after resting for a long time. The joints can also go red, swell and be painful because the joint lining is inflamed which causes extra synovial fluid to be produced and the joint lining tissue to get thicker. The early symptoms usually are in small joints of the hands and wrists, and they are pain and stiffness...
Some cells cause inflammation of the tissue, which raises the temperature of the injured area and is adaptive because it prevents pathogens from entering and spreading into the host. The area of injured tissue also remains very sensitive to pain in order to avoid any type of stimuli
As you exit the bus, another passenger next to you starts to cough, and then you hold the handrail as you exit the bus. Since you’re late getting home, you take a shortcut through a field to get home quicker. These three simple acts just exposed you to bacteria, viruses, and insects that could cause illness or even death. Infectious diseases, also known as communicable disease, are spread by germs. Germs are living things that are found in the air, in the soil, and in water. You can be exposed to germs in many ways, including touching, eating, drinking or breathing something that contains a germ. Animal and insect bites can also spread germs.1
Throughout history disease has run rampant taking many lives with every passing day. Finding a cure or even just a tool in the battle has been the main focus of scientist throughout time. This focus is what brought us the discovery of antibiotics. Over the years antibiotics have been misused by patients, over prescribed by physicians and have led to resistant strains of bacteria.
. Many doctors and patients are unaware that antibiotics are designed to treat bacterial infections, not viral infections (Antibiotic resistance, N.D.). Many bacteria within our bodies are not harmful at all, and some of them actually provide health benefits. The bacteria that are harmful are disease-causing bacteria, which generate sicknesses such as strep throat, the common cold, and ear infections (Get, 2013). Viruses are smaller than bacteria and require hosts, such as plants or animals, in order to proliferate (What, N.D.). Doctors play a vital role in administering antibiotics, for patients rely on their knowledge and expertise in order to receive proper medication for ailments throughout their lives. According to www.acponline.org, 190 million doses of antibiotics are administered every day. Among patients that do not reside in hospitals, doctors prescribe more than 133 million antibiotic programs every year. Of those 133 million programs, it is estimated that over 50 percent of them are unnecessarily prescribed because the doctor is prescribing them for viral infections such as common colds or simple coughs (Antibiotic resistance, N.D.). However, doctors are not the only ones to blame in regard to misuse of antibiotics because their patients are just as guilty when it comes to ignorance in respect to antibiotic usage. Many preventable factors have emerged because of irresponsibility of patients, including self-medication practices and the temptations of cheap, counterfeit drugs, all of which have aggravated drug resistance in the last 20 years (What, N.D.). Also, many patients are unaware of the dangers that can result from leaving medication behind because they don’t use it. It is extremely ill-advised to leave behind eve...
ANTIBIOTICS :- Antibiotics are medicines that fight bacteria. Antibiotics can save lives, if used properly. Antibiotics either kill bacteria or keep them from multiplying. Antibiotics do not fight virus infections. For example: Cold Flu ANTIBIOTICS: Most coughs Sore throats (Exception: strep throats).
The inflammatory response is a nonspecific response to cellular injury and bacterial invasion. Inflammation is the primary defense in early gingivitis. Biofilm can initiate an inflammatory response if it is left undisturbed for as little as seventy two hours. Redness and swelling are two of the cardinal signs of inflammation and can be observed clinically in gingivitis. Histamine is released by mast cells and responsible for the redness and swelling of tissues. Histamine causes both an increase in vascularity and permeability of blood vessels at the site of injury. Swelling may occur in response to the accumulation of fluid at a specific site. The inflammatory response includes cellular components of the immune system polymorphonuclear leukocytes and macrophages. Polymorphonuclear leukocytes are crucial to the cellular immune response. Polyporphonuclear leukocytes are the first cells that arrive at an inflammatory site. Polymorphonuclear leukocytes arrive at the site via chemotaxis, and begin to phagocytize bacteria. As the disease continues and the inflammatory reaction is not strong enough to subside the bacterial infection the immune response is further
“But you don't look sick.”. “If you just exercised more you would feel better.” , “It's all in your head.” , “You are just being lazy.”. These phrases are just a hand full of unkind things that people have said to me, simply because they do not understand my disease. Who could blame them? Doctors do not understand it. Researchers do not understand it. My parents do not understand it. My boyfriend does not understand it. Even I cannot understand it. I have Lupus. It is an unresolved disease that millions of people suffer with. Though there are numerous people diagnosed with lupus, there are very few people who know what it is, and how it impacts us from the time we wake up, to when we finally escape our pain with sleep. In this essay, I will explain what we know about lupus, what the symptoms are, and what kind of treatments are accessible for lupus.
One of the most common mysteries in the world is the development of autoimmune diseases. An autoimmune disease is when the immune system, which usually keeps your body healthy thinks that your healthy cells are antigens and attacks them. This is irony right? It is against properties of evolution for an immune system to attack itself causing sickness and possibly death if untreated. There are about 80 different types of autoimmune diseases, which usually have periods of little to no symptoms and worsening symptoms. What particularly creates confusion in the world is the autoimmune disease, inflammatory bowel disease, which affects almost about five million people worldwide.
Patients who usually have allergies suffer from many symptoms due to the allergic reaction(s). Normally, your immune system protects you against invading agents such as bacteria and viruses. Otherwise harmless allergens (allergy-producing substances) cause your body to react as if they were dangerous invaders. In effect, your immune system is responding to a false alarm.
Handling and caring for rodents (including hamsters and gerbils) or even fish, puts humans at risk for the below-mentioned infections.
