Valvular stenosis is the hardening of the valves in the heart: mitral, tricuspid, pulmonary, and/or aortic. Stenotic valves are either too thick, stiff, or are fused together causing it to not open or close all the way like it normally should. This causes a decrease in blood flow to the next chamber of the heart. If one or more valves become diseased, pooling of blood in a chamber will occur, or the blood will leak backwards, and flow will slowly occur in the opposite direction. The causes of the stenosis includes calcification, rheumatic fever, and other congenital factors.
In cases of mitral and tricuspid valve stenosis, its cause is related to rheumatic fever, which is most commonly ...

...cification as well. Echocardiograms are most likely to be done as well. This is usually the primary test done to help narrow down the possibilities of diseases and confirms diagnosis. The cardiologist or a cardiac sonographer takes ultrasound specifically of the heart and its chambers. This helps to check for any abnormalities in the valve and its severity, so the doctor can choose a suitable treatment. Cardiac catheterization, computed tomography, and magnetic resonance imaging are more definite test. These tests are conclusive and provide a firm diagnosis. With these test, doctors inject dye into the blood vessels to help show flow of blood and how much is being ejected into the systemic circulation. Cardiologists use treatments such as balloon valvuloplasty, permanent valve replacement, and trans catheter aortic valve replacements (TAVR) to correct the disorder.

- Celiac disease is becoming a more common autoimmune condition. According to “Oral Diseases,” celiac disease is the most common genetically induced food intolerance. (Rivera 2013). People who have celiac disease cannot properly digest gluten; therefore it damages the small intestine. This disease does not occur at a specific age. It can happen at any time and is accompanied by many signs and symptoms. Looking at chart 1 below, celiac disease can happen anywhere from 2 years old to over 20 years old....

- Huntington’s Disease (HD) is a devastating neurodegenerative disorder of the central nervous system characterized by involuntary movements, progressive cognitive impairment and neuropsychiatric symptoms. The disease follows an autosomal dominant pattern of inheritance with a prevalence of 1/10 000 among individuals of European descent. The mutation underlying the disease is the abnormal expansion of the CAG repeat block in exon1 of the IT15 gene. Four CAG repeat size intervals associated with varying disease risk were established.... [tags: Disease ]

- 1.1. Background on Sickle Cell Disease Sickle cell disease is a disease that is most prevalent in people of African descent along with people of Mediterranean and Middle Eastern origin. This disease is known to affect about 70, 000 Americans and about 2 million people carry the trait (meaning that, they carry a single gene mutation). Sickle Cell Disease is an autosomal recessive genetic disease that occurs due to a mutation in the β-globin gene of hemoglobin. Autosomal meaning that it is not linked to a sex chromosome, so either parent can pass on the gene to their child.... [tags: Disease]

- Cardiovascular diseases are also known as heart diseases. This is a class of diseases that affect the heart and the blood vessels. The blood vessels are the arteries, capillaries and the veins. Principally, cardiovascular diseases are diseases that affect the cardiovascular system. Therefore, they include diseases that affect the heart, vascular diseases that affect the brain and the kidney, and peripheral arterial diseases. Cardiovascular diseases are caused by atherosclerosis and hypertension.... [tags: Valvular Conditions, Myocardial Infarction]

- Throughout human history disease has been linked to many facets of life and even the rise and fall of entire civilizations. Biological, social, political and economic forces have all influenced how the outbreak of disease is handled. Epidemics have altered history in how they have developed and the impact that they have had. In turn, epidemic management has been influenced by history and governments as humans have learned to cope with outbreaks and the social and political implications that result from them....

- Celiac Disease is an inflammatory disease that destroys the lining of the small intestines and prevents the absorption of nutrients and vitamins into the system. The patients' health suffers; their digestive system is unable to process gluten foods that contain wheat, barley, and oats. The cause of this disease is unknown; however, environmental factors and a genetic predisposition are suspected. Destructive proteins that contain an abundance of proline and glutamine and the amino acid sequences Pro-Ser-Gln-Gln and Gln-Gln-Gln-Pro) are involved.... [tags: Disease ]

- Huntington's Disease Huntington's disease is an autosomal dominant disorder, which is found on the # 4 chromosome. George Huntington discovered it in 1872. It mainly has an effect on the nervous system. There are around 210,000 bases between D4S180 and D4S127. The disease itself is found in 2% of people in their childhood, and in 5% of the people they were older then 60. (Miller p 16) In the majority of the affected people the disease is detected between the ages of 35-45. In males the disease begins around the time of their childhood.... [tags: Disease]

- By close reference to “More Than Just The Disease”, show what feelings you have for Neil in the course of the story. What lessons do you suppose he has learned by the end of it. In the story, “More than Just the Disease”, Neil who was away from home for a holiday with the Middleton family experienced and learned much. The best part was how Neil managed to take the first step of overcoming his shyness, not to “suffer from more than just the disease”.
