Pressure ulcers are caused by constant pressure being applied to a certain part of the body. The pressure will affect the blood supply to the affected area, without this constant blood supply tissue will eventually become damaged and die. The skin will no longer receive the white blood cells it needs to fight infection, when an ulcer develops it can become infected with bacteria.…
3) In addition to the information in the case presentation (including the web sites contained in the case itself), what other information did you find to determine whether this study represents a successful application of the process of scientific inquiry? For example, you found other studies that reviewed the power of the research method or…
No single cause has been found for ulcers. However, it is now clear that an ulcer is the end result of an imbalance between digestive fluids in the stomach and duodenum. Peptic Ulcers can be caused by:…
Ulceration is caused by hypoxia, which is a decrease in the amount of oxygen reaching the tissues. Limiting the amount of oxygen can cause ulceration from minor trauma from the decreased capability of the body to respond to cellular demand. Ulceration can also be caused by the increased vascular permeability causing fibrin to adhere to the capillary walls. The barrier can also cause hypoxia. The increase in blood flow from venous htn triggers an inflammatory…
The extra pressure disrupts the flow of blood through the skin. Without a blood supply, the affected area of skin becomes starved of oxygen and nutrients. It begins to break down, leading to the formation of an ulcer.…
Keratoconus is a disease of the eye that is common sometimes. This syndrome can affect many people who can have very serious problem. There are many different backgrounds of the keratoconus such as history, what is keratoconus, causes of the diseases, symptoms, signs and diagnosis, and other treatments.…
1.1 Pressure sores also known as pressure ulcers are injuries to the skin and underlying tissue, they appear when an area is under too much pressure for long periods of time, due to this pressure the blood flow id disrupted, and the area doesnt get irrigated, therefore the nutrients and oxygen do not reach the skin cells, the skin then breaks and the pressure ulcers form.…
Pellucid Marginal Degeneration is a rare corneal ectatic disorder(PMC). This bilateral, non-hereditary , idiopathic disorder is characterized by irregular astigmatism(Collagen cross-linking in the treatment of pellucid marginal degeneration)and thinning of the peripheral cornea in absence of inflammation, often affecting the inferior quadrant in a crescentic fashion. The disorder includes an area of corneal protrusion above the point of maximal thinning. This is the hallmark of the disorder and is what distinguishes it from Keratoconus.…
Macular holes are a hindrance for patients. They can cause massive vision loss, typically 20/200 or worse, that cannot be recovered.1 A patient who experience any vision loss can have an affect on person’s mental health and degrade their quality of life. The most common cause of macular holes is idiopathic, or unknown origins, however, there are signs of macular holes beginning to form that doctors can look out for.2,3,4 One of these etiologies is vitreomacular traction (VMT), or pulling on the macula from the vitreous. This happens due to an abnormally strong adhesion of the vitreous to the macula and the natural progression of shrinking of the vitreous4. This strong adhesion allows fluid to pool in the retinal layers and the macula to swell.3,4…
What are the causes of cataracts? The lens has a makeup of mostly water and protein. Some of the proteins are responsible for maintaining the clarity of the lens but over the years the structure of the proteins in the lens are altered, which leads to the gradual clouding of the eyes; Cataracts can be present at birth or even in early childhood but it’s very rare. Severe trauma to the eye and even eye surgery can also cause cataracts to occur early. Other factors that could lead to cataracts at an early age would be excessive ultraviolet exposure, diabetes, smoking or the use of medications such as oral, topical or inhaled steroids. Cataracts can occur in one or both of the eyes but one eye has to be worse than the other.…
A cornea transplant is a surgical procedure to replace part of the cornea with corneal tissue from a deceased donor. Cornea transplant apply for people who have vision problem caused by thinning of the cornea, severe infections or injuries to scarring of the cornea or vision loss caused by cloudiness of the cornea. The method of cornea surgery is complex. Sometimes, the body rejects the transplant tissue. This occurs in a small number of patients (The New York Times). It occurs in about one out of three patients in the first five years (Medline Plus). According to Alabama Eye Bank, more than 90% of cornea transplant operations successfully restore the recipient’s vision. Other dangers for a corneal transplant are bleeding, infection of the eye, Glaucoma (high pressure in the eye than can cause vision loss) and swelling of the front of the eye (Medline Plus). Certainly, the medical provider would take every possible precaution to prevent such complications because it can permanently damage the eyes.…
An ulcer is a crater like lesion or erosion in a membrane. Ulcers develop in the alimentary canal, which is exposed to acidic gastric juice.…
As we get older, gravity becomes our biggest enemy. It fights us every step of the way, and eventually we have no choice but to give in. Our skin seems to be affected the most. It starts to droop and sag right in front of our eyes, not to mention underneath them. Bags under eyes are a common and inevitable sign of aging. During our youth, healthy skin and muscles do their best to hold fat back, but as we get older, they start to lose that battle and we end up with puffy bags outlining our eyes.…
My partner and I decided to research about this because we encountered this problem when cutting onions. It irritates us and it affects our performance when cutting onions so we’re finding the best way to avoid it; in this way, irritation in our eyes while cutting onions will lessen problems while cutting onions.…
