Melanoma Assignment

1. Bill could choose from the three options

- Surgery

- Chemotherapy

- Radiation Therapy

2. I think Bill should have the melanoma removed through surgery, because it is in one of the earlier stages and only the dermis is affected. Then to ensure that any of the melanoma that may have spread is killed he should undergo sessions of chemotherapy.

Bill's Options

Bill's options are.....

1. Surgery- The tumor and some of the surrounding tissue would be removed.
2. Chemotherapy- Drugs that kill cancer cells are given to the patient, but it has side affects such as nausea, vomiting, hair loss, and mouth sores.
3. Immunotherapy- This method uses your body's immune system to fight cancer or to lessen the side effects that can be caused by cancer treatments like chemotherapy.


Because Bill's cancer is in an early stage, I think that surgery is the best option for him. It would be the simplest option and would cause the least amount of side effects.

What should Bill Do?

Three treatments that Bill could choose as options are surgery, chemotherapy, and simple excision. Each of these would be a good option for him, but in my opinion I think that Bill should get the spot surgically removed. Knowing this kind of cancer, it will eventually spred to other organs or tissues and could get more severe than it already is. The sooner he makes his decision, the better off he will be before more problems come of the cancerous cells. Going through surgery to remove the whole spot would most likely be the most successful.

Bill's Treatment

1. Three possible treatments include
Surgical Excision: All parts of discoloration or raised parts of the tumor are surgically removed.
Chemotherapy: Either one or a combination of a few drugs are injected into the infected area.
Gene Therapy: A change is made to a patient's genetic code to stop uncontrollable cell growth that causes cancer
2. I think Bill should have the tumor surgically excised. This is the least invasive procedure of the three choices. It doesn't have any major side effects and it's the most proven way of eliminating a cancerous tumor.

Bill's Options

Bill has three options for removing his melanoma; surgery, radiation therapy, and chemotherapy. I think that Bill should choose to get his melanoma surgically removed. The tumor is localized and it is still a relatively small size. Radiation therapy may be too strong for such a small tumor and chemotherapy is usually used for cancer that is too far gone.

Melanoma treatment

bill has a couple of choices he can have surgery to remove the cancerous cells, radiation therapy, and chemotherapy. I think the best treatment option is radiation therapy. this is the best option because surgery has the risk of missing cancerous cells. Chemotherapy kills normal cells that rapidly divide such as hair and blood cells. Radiation therapy not only kills,but keeps cancerous cells from growing and dividing.
Bill has three choices of which treatment he can use for his malignant cancer. Surgery on the particular cells, chemotheropy, and clinical theropy will all work to help Bill. I think the best treatment for Bill to have is the chemotherapy. Surgical procedures would not work as effectively for the caner cells have spread therefor there would need to be more surgical procedures done. I also feel as though clinical trial may take too long and the cancerous cells will not be controlled as soon as the patient is diagnosed.

Melanoma Treatment

Some different treatments for Melanoma are surgery, radiation, or chemotherapy.

Surgery: The tumor or cancerous cells are cut from the skin, and so is some of the surrounding tissue. This treatment is known to be the most successful.

Radiation: High energy X-Rays are used to kill the cancer cells and to prevent their growth through the use of an outside machine, known as external radiation, or through radioactive needles and wires called internal radiation.

Chemotherapy: Drugs are used to stop the growth of cancer cells by killing them or halting their dividing. The drugs can be taken in the form of a pill or injection, or applied as a cream. However, the lotion/cream form can possibly cause inflammation and scarring. This type of treatment is used to treat skin cancer that has spread.

Bill's best option would be surgery since his cancer is still small and in one area. Radiation or chemotherapy would be a poor choice since they are commonly used for widespread cancer, carry more harmful effects, and aren't as successful as a surgical removal of the tumor.

Bill's Case

The options Bill could choose is chemotherapy, surgically removed, or radiation therapy.
The treatment Bill should choose is to have the mole surgically removed since his spot is already malignant. If his tumor isn't taking care of, his cancer could end up spreading to other areas of his body. Having malignant cells causes the body to eventually attract cancer to other areas of the body.

Melanoma

Three types of treatment
Chemotherapy- Using drugs to kill cancer cells
Radiation therapy- using radiation to kill cancerous cells and shrink tumors
surgery- removing tumor from body

Bill should have the tumor removed through surgery. He is still in the early stages of melanoma, so the tumor is local to one area still, and it is easier to catch before it spreads. Also because it has not spread they can remove it all at one time, without suing strong drugs or the harmful effects of radiation.

My Decision

1.
radiation therapy
Radiation therapy uses a radiation machine that emits x-rays to kill cancer cells and shrink tumors.

surgery
Surgery is a common treatment for skin cancer -- used about 90 percent of the time

biological therapy (sometimes called biological response modifier (BRM) therapy, or immunotherapy)
Biological therapy tries to get your own body to fight cancer by using materials made by your own body, or made in a laboratory, to boost, direct, or restore your body's natural defenses against disease.

2. I think the simple excision surgery would be best for Bill. Because, the cancer has not yet spread to other parts of his body. Also during this procedure they remove some healthy skin around the site too just in case it did happen to leave some active cites behind.

Assignment 2 - What should Bill do?

1.Three Treatments

surgery
Surgery is a common treatment for skin cancer -- used about 90 percent of the time, and often includes the following procedures:

  • cryosurgery - freezing the tumor, which kills cancer cells.

  • electrodesiccation and curettage - burning the lesion and removing it with a sharp instrument.

  • grafting - uses a skin graft to replace skin that is damaged when cancer is removed.

  • laser therapy - using a narrow beam of light to remove cancer cells.

  • Mohs micrographic surgery - removing the cancer and as little normal tissue as possible. During this surgery, the physician removes the cancer and then uses a microscope to look at the cancerous area to make sure no cancer cells remain.

  • simple excision - cutting the cancer from the skin along with some of the healthy tissue around it.

radiation therapy
Radiation therapy uses a radiation machine that emits x-rays to kill cancer cells and shrink tumors.


chemotherapy
treatment with drugs to destroy cancer cells.

topical chemotherapy - chemotherapy given as a cream or lotion placed on the skin to kill cancer cells.

systemic chemotherapy - chemotherapy taken by pill, or needle injection into a vein or muscle.

2. Which should Bill choose?
In my opinion, i believe Bill should start with the surgery to remove his skin cancer. It is used 90% of the time and is safer than most other treatments which proves it is the most efficient. There are even six different steps to ensure Bill that the cancer can be fully removed. Most of the treatments range from 5 minutes to 200 minutes to complete the procedure. Bill's cancer hasn't spread throughout the entire body so i believe it is safer to follow through with getting surgery on the tumor.
Skin Cancer Case part 2

Bill has a few options for his cancer treatment.
  • Radiation Therapy: doctors use a type of energy to kill cancer cells and shrink tumors.
  • Surgery: The doctor could just remove the tumor as long as it hasn't spread and even if it did nthey could do further treatment after that.
  • Chemotherapy: doctors use chemicals to kill the cancer cells even if the cells have spread far away from the original area.
In my opinion i think they should just remove the cancerous tumor with surgery just because it hasn't spread to any other part of the body. If they found that it did spread i would suggest chemotherapy because many people have used it with success. It could kill whatever cancer cells have spread.

Melanoma Part II

1. Treatments:
Surgical Removal- involves removal of affected skin and is most effective treatment
Radiation Therapy- uses high-dose x-rays to destroy cancer cells and shrink tumors
Chemotherapy- involves the use of medicine to destroy cancer cells

2. I think the best treatment for Bill would be surgical removal because it has been proven to be the most effective treatment. Also, the entire melanoma along with the border of normal-appering skin is removed to make sure it is all gone. Surgical removal can cure melanoma in the first two stages of cancer, and also in stage III if the lymph nodes are removed.

Skin Cancer Assignment

How is it treated?
The treatment plan takes into account the type of melanoma, its location, whether it has begun to spread, and the person's age and health. The standard treatments are:
  • Surgery - remove the melanoma and a ring of tissue around it (to make sure no cancer cells were missed).
  • Chemotherapy - to kill cancer cells that have spread throughout the body.
  • Immunotherapy - interferon-alfa and interleukin-2 may be given to help the body's immune system prevent a recurrence of the melanoma.
  • Radiation therapy - to kill cancer cells that may have spread beyond the tumor.

I think the treatment for Bill is

  • Surgery because it removes the cancer cells and stops from spreading throughout the body.

assignment number 1


Disease: Lung Cancer

One fourth of all people with lung cancer have no symptoms when the cancer is diagnosed. These cancers are usually identified incidentally when a chest x-ray is performed for another reason. The other three fourths of people develop some symptoms. The symptoms are due to direct effects of the primary tumor; to effects of metastatic tumors in other parts of the body; or to malignant disturbances of hormones, blood, or other systems.
Symptoms of primary lung cancers include cough, coughing up blood, chest pain, and shortness of breath.

  • A new cough in a smoker or a former smoker should raise concern for lung cancer.

  • A cough that does not go away or gets worse over time should be evaluated by a health care provider.

  • Coughing up blood (hemoptysis) occurs in a significant number of people who have lung cancer. Any amount of coughed-up blood should cause alarm.

  • Chest pain is a symptom in about one fourth of people with lung cancer. The pain is dull, aching, and persistent and may involve other structures surrounding the lung.

  • Shortness of breath usually results from a blockage in part of the lung, collection of fluid around the lung (pleural effusion), or the spread of tumor through the lungs.

  • Wheezing or hoarseness may signal blockage or inflammation in the lungs that may go along with cancer.

  • Repeated respiratory infections, such as bronchitis or pneumonia, can be a sign of lung cancer.
The body systems that are affected are the respiratory system, because lung cancer mainly affects the lungs, which are a main part of that system.

Leukemia

What is Leukemia?

Leukemia is cancer that starts in the tissue that forms blood. In a persons body that is healthy, or without leukemia, their white blood cells die after a certain period of time. White blood cells are used to fight infection. Red blood cells carry oxygen throughout the body. White blood cells, red blood cells, and platelets are made from stem cells as the body needs them. When cells grow old or get damaged, they die, and new cells take their place. Unlike normal blood cells, leukemia cells do not die when they should. They may crowd out normal white blood cells, red blood cells, and platelets. This makes it hard for normal blood cells to do their work, which causes many other problems for the persons body. Experts do not know what causes this disease but you are more likely to get it if you have been exposed to large amounts of radiation, exposed to different chemicals, have genetic problems, or smoke. There are various kinds of leukemia, but chronic and acute will be the ones focused on.

What are the symptoms?

People with chronic leukemia may not have symptoms. The doctor may find the disease during a routine blood test. People with acute leukemia usually go to their doctor because they feel sick. If the brain is affected, they may have:
-->headaches
-->vomiting,
-->confusion,
-->loss of muscle control,
-->seizures.
Leukemia also can affect other parts of the body such as the digestive tract, kidneys, lungs, heart, or testes. Common symytoms for these kinds of leukemia are:
-->swollen lymph nodes that usually don't hurt, most common in the armpit or neck
-->fevers or heavy sweating throughout the night
-->feeling weak or tired
-->bleeding and bruising easily (bleeding gums, purplish patches in the skin, or tiny red spots under the skin)
-->swelling or discomfort in the abdomen (from a swollen spleen or liver)
-->weight loss
-->pains in the joints or bones.

What body systems are affected?

Integumentary
Cardiovascular
Immune
Muscular
Skeletal

ELEPHANTIASIS:

Symptoms:
Elephantiasis is characterized by the gross enlargement of a limb or areas of the trunk or head. There is an abnormal accumulation of watery fluid in the tissues (edema) causing severe swelling. The skin usually develops a thickened, pebbly appearance and may become ulcerated and darkened. Fever, chills and a general feeling of ill health (malaise) may be present.
Elephantiasis may also affect the male and female genital organs. In a male, there may be enlargement of the scrotum, and the penis may be retracted under skin which has become thickened, nonelastic, hot and painful. The spermatic cords may become thickened.
The external parts of the female genital organs (vulva) may also be affected by elephantiasis. A long, tumorous mass covered by thickened and ulcerated skin may develop between the thighs. There may also be an enlargement of the lymph nodes of the legs.

Causes:
The extreme enlargement of the limbs and other areas of the body characterized by elephantiasis, is the result of obstruction of the lymph flow and possibly of blood circulation. The lymphatic blockage can be due to recurrent attacks of a bacterial infection which causes inflammation of the lymphatic vessels (streptococcal lymphangitis). When the lymphatic obstruction is large enough, back pressure in the lymphatic channels produces dilation of the superficial vessels, resulting in extreme swelling. Without medical intervention, the cycle continues until the affected area is grotesquely enlarged. Death of surrounding tissues may also occur from an obstructed blood supply (gangrene).
Recent studies have shown that a possible cause of elephantiasis in Africa may be related to the red soil on which certain barefooted populations live. It is believed that small chemical particles found in the soil may enter the skin through the bare feet. These particles then lodge in the lymphatic tissues and produce irritating effects. The traumatized tissue is then vulnerable to streptococcal infection.

diabetes




Symptoms of this disease: some of the many symptoms of diabetes are increased urination, sometimes leading to "bedwetting" and urinating as frequently as every hour. dehydration because of the build up of glucose in the blood, and the body trying to rid of it using up a large amount of the bodys water supply. a diabetic coma is also possible from extreme dehydration when the person is not able to replenish their fluids fast enough from the excessive urination.




Body system(s) affected: the pancreas produces insulin that breaks down sugars mal-functions. your circulatory system is filled with all the glucose that could not be delt with by the insulin so then the kidney kicks into overdrive and tries to expell the extra glucose through the urinary system.







if insulin is not administered manually, the person will die because of not being able to process the sugars.

Assignment #1 Diseases

What is celiac disease?

Celiac disease is a digestive disease that damages the small intestine and interferes with absorption of nutrients from food. People who have celiac disease cannot tolerate gluten, a protein in wheat, rye, and barley. Gluten is found mainly in foods but may also be found in everyday products such as medicines, vitamins, and lip balms.


The small intestine is shaded above.

When people with celiac disease eat foods or use products containing gluten, their immune system responds by damaging or destroying villi—the tiny, fingerlike protrusions lining the small intestine. Villi normally allow nutrients from food to be absorbed through the walls of the small intestine into the bloodstream. Without healthy villi, a person becomes malnourished, no matter how much food one eats.


Villi on the lining of the small intestine help absorb nutrients.

Celiac disease is both a disease of malabsorption—meaning nutrients are not absorbed properly—and an abnormal immune reaction to gluten. Celiac disease is also known as celiac sprue, nontropical sprue, and gluten-sensitive enteropathy. Celiac disease is genetic, meaning it runs in families. Sometimes the disease is triggered—or becomes active for the first time—after surgery, pregnancy, childbirth, viral infection, or severe emotional stress.

[Top]

What are the symptoms of celiac disease?

Symptoms of celiac disease vary from person to person. Symptoms may occur in the digestive system or in other parts of the body. Digestive symptoms are more common in infants and young children and may include

  • abdominal bloating and pain
  • chronic diarrhea
  • vomiting
  • constipation
  • pale, foul-smelling, or fatty stool
  • weight loss

Irritability is another common symptom in children. Malabsorption of nutrients during the years when nutrition is critical to a child’s normal growth and development can result in other problems such as failure to thrive in infants, delayed growth and short stature, delayed puberty, and dental enamel defects of the permanent teeth.

Adults are less likely to have digestive symptoms and may instead have one or more of the following:

  • unexplained iron-deficiency anemia
  • fatigue
  • bone or joint pain
  • arthritis
  • bone loss or osteoporosis
  • depression or anxiety
  • tingling numbness in the hands and feet
  • seizures
  • missed menstrual periods
  • infertility or recurrent miscarriage
  • canker sores inside the mouth
  • an itchy skin rash called dermatitis herpetiformis

People with celiac disease may have no symptoms but can still develop complications of the disease over time. Long-term complications include malnutrition—which can lead to anemia, osteoporosis, and miscarriage, among other problems—liver diseases, and cancers of the intestine.

[Top]

Why are celiac disease symptoms so varied?

Researchers are studying the reasons celiac disease affects people differently. The length of time a person was breastfed, the age a person started eating gluten-containing foods, and the amount of gluten-containing foods one eats are three factors thought to play a role in when and how celiac disease appears. Some studies have shown, for example, that the longer a person was breastfed, the later the symptoms of celiac disease appear.

Symptoms also vary depending on a person’s age and the degree of damage to the small intestine. Many adults have the disease for a decade or more before they are diagnosed. The longer a person goes undiagnosed and untreated, the greater the chance of developing long-term complications.

[Top]

What other health problems do people with celiac disease have?

People with celiac disease tend to have other diseases in which the immune system attacks the body’s healthy cells and tissues. The connection between celiac disease and these diseases may be genetic. They include

  • type 1 diabetes
  • autoimmune thyroid disease
  • autoimmune liver disease
  • rheumatoid arthritis
  • Addison’s disease, a condition in which the glands that produce critical hormones are damaged
  • Sjögren’s syndrome, a condition in which the glands that produce tears and saliva are destroyed

How common is celiac disease?

Celiac disease affects people in all parts of the world. Originally thought to be a rare childhood syndrome, celiac disease is now known to be a common genetic disorder. More than 2 million people in the United States have the disease, or about 1 in 133 people.1 Among people who have a first-degree relative—a parent, sibling, or child—diagnosed with celiac disease, as many as 1 in 22 people may have the disease.2

Celiac disease is also more common among people with other genetic disorders including Down syndrome and Turner syndrome, a condition that affects girls’ development.

1Fasano A, Berti I, Gerarduzzi T, et al. Prevalence of celiac disease in at-risk and not-at-risk groups in the United States. Archives of Internal Medicine. 2003;163(3):268–292.

2Ibid.

How is celiac disease diagnosed?

Recognizing celiac disease can be difficult because some of its symptoms are similar to those of other diseases. Celiac disease can be confused with irritable bowel syndrome, iron-deficiency anemia caused by menstrual blood loss, inflammatory bowel disease, diverticulitis, intestinal infections, and chronic fatigue syndrome. As a result, celiac disease has long been underdiagnosed or misdiagnosed. As doctors become more aware of the many varied symptoms of the disease and reliable blood tests become more available, diagnosis rates are increasing.

Blood Tests

People with celiac disease have higher than normal levels of certain autoantibodies—proteins that react against the body’s own cells or tissues—in their blood. To diagnose celiac disease, doctors will test blood for high levels of anti-tissue transglutaminase antibodies (tTGA) or anti-endomysium antibodies (EMA). If test results are negative but celiac disease is still suspected, additional blood tests may be needed.

Before being tested, one should continue to eat a diet that includes foods with gluten, such as breads and pastas. If a person stops eating foods with gluten before being tested, the results may be negative for celiac disease even if the disease is present.

Intestinal Biopsy

If blood tests and symptoms suggest celiac disease, a biopsy of the small intestine is performed to confirm the diagnosis. During the biopsy, the doctor removes tiny pieces of tissue from the small intestine to check for damage to the villi. To obtain the tissue sample, the doctor eases a long, thin tube called an endoscope through the patient’s mouth and stomach into the small intestine. The doctor then takes the samples using instruments passed through the endoscope.

Dermatitis Herpetiformis

Dermatitis herpetiformis (DH) is an intensely itchy, blistering skin rash that affects 15 to 25 percent of people with celiac disease.3 The rash usually occurs on the elbows, knees, and buttocks. Most people with DH have no digestive symptoms of celiac disease.

DH is diagnosed through blood tests and a skin biopsy. If the antibody tests are positive and the skin biopsy has the typical findings of DH, patients do not need to have an intestinal biopsy. Both the skin disease and the intestinal disease respond to a gluten-free diet and recur if gluten is added back into the diet. The rash symptoms can be controlled with antibiotics such as dapsone. Because dapsone does not treat the intestinal condition, people with DH must maintain a gluten-free diet.

Screening

Screening for celiac disease means testing for the presence of autoantibodies in the blood in people without symptoms. Americans are not routinely screened for celiac disease. However, because celiac disease is hereditary, family members of a person with the disease may wish to be tested. Four to 12 percent of an affected person’s first-degree relatives will also have the disease.4

3Rodrigo L. Celiac disease. World Journal of Gastroenterology. 2006;12(41):6585–6593.

4Ibid.

How is celiac disease treated?

The only treatment for celiac disease is a gluten-free diet. Doctors may ask a newly diagnosed person to work with a dietitian on a gluten-free diet plan. A dietitian is a health care professional who specializes in food and nutrition. Someone with celiac disease can learn from a dietitian how to read ingredient lists and identify foods that contain gluten in order to make informed decisions at the grocery store and when eating out.

For most people, following this diet will stop symptoms, heal existing intestinal damage, and prevent further damage. Improvement begins within days of starting the diet. The small intestine usually heals in 3 to 6 months in children but may take several years in adults. A healed intestine means a person now has villi that can absorb nutrients from food into the bloodstream.

To stay well, people with celiac disease must avoid gluten for the rest of their lives. Eating even a small amount of gluten can damage the small intestine. The damage will occur in anyone with the disease, including people without noticeable symptoms. Depending on a person’s age at diagnosis, some problems will not improve, such as short stature and dental enamel defects.

Some people with celiac disease show no improvement on the gluten-free diet. The most common reason for poor response to the diet is that small amounts of gluten are still being consumed. Hidden sources of gluten include additives such as modified food starch, preservatives, and stabilizers made with wheat. And because many corn and rice products are produced in factories that also manufacture wheat products, they can be contaminated with wheat gluten.

Rarely, the intestinal injury will continue despite a strictly gluten-free diet. People with this condition, known as refractory celiac disease, have severely damaged intestines that cannot heal. Because their intestines are not absorbing enough nutrients, they may need to receive nutrients directly into their bloodstream through a vein, or intravenously. Researchers are evaluating drug treatments for refractory celiac disease.

The Gluten-free Diet

A gluten-free diet means not eating foods that contain wheat, rye, and barley. The foods and products made from these grains should also be avoided. In other words, a person with celiac disease should not eat most grain, pasta, cereal, and many processed foods.

Despite these restrictions, people with celiac disease can eat a well-balanced diet with a variety of foods. They can use potato, rice, soy, amaranth, quinoa, buckwheat, or bean flour instead of wheat flour. They can buy gluten-free bread, pasta, and other products from stores that carry organic foods, or order products from special food companies. Gluten-free products are increasingly available from mainstream stores.

“Plain” meat, fish, rice, fruits, and vegetables do not contain gluten, so people with celiac disease can freely eat these foods. In the past, people with celiac disease were advised not to eat oats. New evidence suggests that most people can safely eat small amounts of oats, as long as the oats are not contaminated with wheat gluten during processing. People with celiac disease should work closely with their health care team when deciding whether to include oats in their diet.

The gluten-free diet requires a completely new approach to eating. Newly diagnosed people and their families may find support groups helpful as they learn to adjust to a new way of life. People with celiac disease must be cautious about what they buy for lunch at school or work, what they purchase at the grocery store, what they eat at restaurants or parties, and what they grab for a snack. Eating out can be a challenge. When in doubt about a menu item, a person with celiac disease should ask the waiter or chef about ingredients and preparation or if a gluten-free menu is available.

Gluten is also used in some medications. People with celiac disease should ask a pharmacist if prescribed medications contain wheat. Because gluten is sometimes used as an additive in unexpected products—such as lipstick and play dough—reading product labels is important. If the ingredients are not listed on the label, the manufacturer should provide a list upon request. With practice, screening for gluten becomes second nature.

Assignment #1- Osteoporosis
















Osteoporosis is a disease where a person's bones begin to get thinner, causing much pain and also bone fractures. Risk factors include smoking, being female, aging, low body weight, some medications, and low sex hormones. Symptoms aren't shown for osteoporosis until after a bone is fractured. It can be prevented though, by having enough calcium and vitamin D, regular exercising, medication that prevents it.


Symptoms:
  • backache
  • fracture of wrist, spine, or hip
  • loss of height or a stooped posture
Systems affected
The main body system affected is the skeletal system since the bones can be easily fractured. The endocrine system could also be affected since sex hormones are not produced.

Treatment
The best way to treat osteoporosis is mainly by preventing it in the first place. The best way to prevent it is getting enough calcium and vitamin D, sometimes by taking calcium or vitamin D pills, or by getting a regular amount of exercise. This keeps the bones strong and keeps them from fracturing.

Progeria

Progeria is a rare genetic disease that affects children and accelerates their aging process. There are different forms of Progeria, but the most classic type is Hutchinson-Gilford Progeria Syndrome.



Symptoms or signs of Progeria include:
  • Loss of body fat
  • Growth failure
  • Loss of hair
  • Aged skin
  • Stiff joints
  • Dislocated hip
  • Heart disease
  • Stroke
Body parts affected:
The heart is the number one body part affected since patients with Progeria experience heart disease and an enlarged. The hair, skin, muscles, and bones are also greatly affected.

What Causes Progeria?
Most of the children diagnosed with Progeria have a mutation on the gene that encodes Lamin A, which holds the cell nucleus together. Without the presence of Lamin A, the nucleus becomes unstable. The instability of the nucleus leads to the process of premature aging.

Assignment #1 " Asthma"




Asthma is an inflammatory disorder of the airways of the reapiratory system, which causes attacks of wheezing, shortness of breath, chest tightness, and coughing. This narrowing is typically temporary and reversible, but in severe attacks, asthma may result in death.








Symptoms



  1. Cough with or without sputum (phlegm) production.

  2. Shortness of breath that gets worse with exercise or activity.

  3. Pulling in of the skin between the ribs when breathing (intercostal retractions)

  4. Wheezing



  • Usually begins suddenly.

  • Comes in episodes.

  • May go away on its own.

  • May be worse at night or in early morning.

  • Gets worse when breathing in cold air.

  • Gets worse with exercise.

  • Gets worse with heartburn (reflux).

  • Gets better when using drugs that open the airways (bronchodilators).




Emergency Symptoms




  1. Bluish color to the lips and face.

  2. Decreased level of alertness such as severe drowsiness or confusion, during an asthma attack.

  3. Extreme difficulty breathing.

  4. Rapid pulse.

  5. Severe anxiety due to shortness of breath.

  6. Sweating.




Additional symptoms that may be associated with this disease:




  • Abnormal breathing pattern --breathing out takes more than twice as long as breathing in.

  • Breathing temporarily stops.

  • Chest pain.

  • Nasal flaring.

  • Tightness in the chest.





Treatment


There are two basic kinds of medication for the treatment of asthma:




  1. Long-acting medications to prevent attacks.

  2. Quick-relief medications for use during attacks.




Causes



Asthma is caused by inflammation in the airways. When an asthma attack occurs, the muscles surrounding the airways become tight and the lining of the air passages swell. This reduces the amount of air that can pass by, and can lead to wheezing sounds.



Most people with asthma have wheezing attacks separated by symptom-free periods. Some patients have long-term shortness of breath with episodes of increased shortness of breath. In others, a cough may be the main symptom. Asthma attacks can last minutes to days and can become dangerous if the airflow becomes severely restricted.



In sensitive individuals, asthma symptoms can be triggered by breathing in allergy-causing substances (called allergens or triggers).



Common asthma triggers include:




  • Animals (pet hair or dander).

  • Dust.

  • Changes in weather (most often cold weather).

  • Chemicals in the air or in food .

  • Exercise .

  • Mold .

  • Pollen.

  • Respiratory infections, such as the common cold.

  • Strong emotions (stress).

  • Tobacco smoke.




Prognosis



There is no cure for asthma, although symptoms sometimes improve over time. With proper self management and medical treatment, most people with asthma can lead normal lives.





Complications



The complications of asthma can be severe. Some include:




  • Death .

  • Decreased ability to exercise and take part in other activities.

  • Lack of sleep due to nighttime symptoms .

  • Permanent changes in the function of the lungs.

  • Persistent cough.

  • Trouble breathing that requires breathing assistance (ventilator).

Albinism Disease

https://eobiology.wikispaces.com/file/view/Albinisitic_man_portrait.jpg


Albinism

Alternative Names
Oculocutaneous albinism; Ocular albinism; Hermansky-Pudlak syndrome

The symptoms of albinism depend on the specific type of albinism.

Symptoms of the eye:
Decreased sharpness in vision (visual acuity)
Functional blindness
Irregular and rapid eye movement (Nystagmus)
Lazy Eye (Amblyopia)
Sensitivity to bright lights or glare (Photophobia)
Wandering eyes (Strabismus)
Distortion of a viewed image (Astigmatism)

Symptoms affecting the skin:
Patchy or absence of the melanin pigment leaving the areas pale
No pigmentation resulting in white skin
Increased susceptibility to skin cancer
Highly sensitive to sunburns

Symptoms of the hair:
Forelock (portion of the hair near the forehead) turns white
Complete absence of pigment in the hair resulting in white hair

Other symptoms:
Bleeding tendency
Increased susceptibility to infections
Problem with bowels
Nervous system disorders
Breathing problems due to Lung fibrosis
Deafness

Body Systems Affected:
Albinism is a recessive inherited defect in melanin metabolism in which pigment is absent from hair, skin, and eyes (oculocutaneous albinism) or just from the eyes (ocular albinism). Melanin is a dark biological pigment that is formed as an end product of the metabolism of the amino acid tyrosine. When human skin is exposed to sunlight it gradually darkens or tans due to an increase in melanin. Tanning helps protect the underlying skin layers from the sun's harmful ultraviolet rays.

Facts:
In the past, albinos were often regarded with fear or awe. Sometimes they were killed at birth, although albino births were common enough in some groups not to cause any excitement. For example, among the San Blas Indians of Panama, one in approximately 130 births is an albino. In the mid-nineteenth century, albinos were exhibited in carnival sideshows. Whole families were displayed at times and were described as a unique race of night people. They were said to live underground and to come out only at night when the light was dim and would not hurt their eyes.

Systemic lupus erythematosus (SLE)


This is a photo of Gordon K. Klintworth who suffers from SLE. This picture shows one of the many symptoms which is skin rash. It mainly affects the face but can spread over the body.


http://eyepathologist.com/images/w2274.jpg







Systemic lupus erythematosus (SLE) is a chronic, inflammatory autoimmune disorder. It may affect the skin, joints, kidneys, and other organs.

Symptoms

Symptoms vary from person to person, and may come and go. The condition may affect one organ or body system at first. Others may become involved later. Almost all people with SLE have joint pain and most develop arthritis. Frequently affected joints are the fingers, hands, wrists, and knees.

Inflammation of various parts of the heart may occur as pericarditis, endocarditis, or myocarditis. Chest pain and arrhythmias may result from these conditions.

General symptoms include:

  • Arthritis
  • Fatigue
  • Fever
  • General discomfort, uneasiness or ill feeling (malaise)
  • Joint pain and swelling
  • Muscle aches
  • Nausea and vomiting
  • Pleural effusions
  • Pleurisy (causes chest pain)
  • Psychosis
  • Seizures
  • Sensitivity to sunlight
  • Skin rash -- a "butterfly" rash over the cheeks and bridge of the nose affects about half of those with SLE. The rash gets worse when in sunlight. The rash may also be widespread.
  • Swollen glands

Additional symptoms that may be associated with this disease:

  • Abdominal pain
  • Blood disorders, including blood clots
  • Blood in the urine
  • Coughing up blood
  • Fingers that change color upon pressure or in the cold
  • Hair loss
  • Mouth sores
  • Nosebleed
  • Numbness and tingling
  • Red spots on skin
  • Skin color is patchy
  • Swallowing difficulty
  • Visual disturbance

Assignment 1 - Huntington's Disease


















Symptoms
Huntington's disease is known to produce three types of symptoms: movement, cognitive, and psychiatric.

Movement
Uncontrolled movement, or tics, may develop in the fingers, feet, face, or trunk. This is the beginning stage of chorea—involuntary, rapid, ceaseless movement. Chorea can become more intense when the person is anxious or disturbed. Over time other symptoms, such as the following, emerge:
  • Clumsiness
  • Jaw clenching (bruxism)
  • Loss of coordination and balance
  • Slurred speech
  • Swallowing and/or eating difficulty
  • Uncontrolled continual muscular contractions (dystonia)
  • Walking difficulty, stumbling, falling


Cognitive
Over time judgment, memory, and other cognitive functions begin to deteriorate into dementia. As Huntington's disease progresses, the ability to concentrate becomes more difficult. The person may have difficulty driving, keeping track of things, making decisions, answering questions, and may lose the ability to recognize familiar objects.

Psychiatric
Early psychiatric symptoms of Huntington's disease are subtle, varied, and easily overlooked or misinterpreted.Depression is the most common psychiatric symptom of Huntington's and often develops early in the course of the disease. Signs of depression include:
  • Hostility/irritability
  • Inability to take pleasure in life (anhedonia)
  • Lack of energy

Some people develop manic-depression, or bipolar disorder, during the course of the disease.

A person with Huntington's also may exhibit psychotic behavior:

Body Parts Affected
The only Organ Systems in the body that is affected by Huntington's Disease is the Nervous System, Skeletal System and Muscle System. It is an inherited disorder of the brain that leads to uncontrolled movement, emotional instability, and loss of intellectual faculties. HD also causes certain nerve cells in your brain to disappear. People affected by this disease may not be able to move like they used to thus causing their Skeletal and Muscle Systems to not work as properly.

Other Facts
An affected parent can pass Huntington's Disease along to his or her offspring, and each child has a 50 percent chance of inheriting the HD gene and developing the disease. It occurs throughout the world in all ethnic groups. Clinical onset is usually between 30 and 50 years of age.

Lyme Disease

This photo shows the site of a bite of a tic and the "ring" formed around it. This is a sign of Lyme disease.

Symptoms
The first sign of infection is usually a circular rash called erythema migrans or EM. This rash occurs in approximately 70-80% of infected persons and begins at the site of a tick bite after a delay of 3-30 days. A distinctive feature of the rash is that it gradually expands over a period of several days, reaching up to 12 inches (30 cm) across. The center of the rash may clear as it enlarges, resulting in a bull's-eye appearance.Some patients develop additional EM lesions in other areas of the body after several days. Patients also experience symptoms of fatigue, chills, fever, headache, and muscle and joint aches, and swollen lymph nodes.

Body parts effected
Loss of muscle tone on one or both sides of the face (called facial or "Bell's palsy), severe headaches and neck stiffness due to meningitis, shooting pains that may interfere with sleep, heart palpitations and dizziness due to changes in heartbeat, and pain that moves from joint to joint.


( I had this disease three summers ago and i fugued it would be interesting to learn more about it. I had a similar ring located on my right scapular region and it took up most of my entire back. It was caught in the early stage so it wasn't too much of a harm to me and, it was quickly cured.)

Assignment #1 - Diseases

Diseases of the Human Body
An introduction to what can “go wrong” with each organ system

When the human body is not working properly we say that someone has a disease. Sometimes a disease is caused by a bacteria, virus, fungus, or animal that has taken up residence within our bodies, these are usually thought of as "infectious" diseases. When we are sick the body is trying to fight off the invader. Some diseases and conditions are not fully understood as to how or why they originate, and may have multiple factors; these can range from bedwetting or migraines to diabetes or cancer. Other diseases are passed on in families, these are called genetic diseases or genetic disorders. Diseases disrupt normal body functioning (homeostasis), causing the breakdown of one or more body systems. Physical injuries include breaks, sprains, etc also disrupt normal body functioning.

Assignment:
1. Research and post about any disease. In your post, include the following:

  • Symptoms of this disease.
  • Body system(s) affected.
  • A related photo. It might be a picture of a broken bone, a tumor, rash, bacteria, etc.
  • List the source(s) of your research and photo.
  • Any other interesting / disgusting information, if desired.

2. Comment on at least 2 classmates’ posts. In your comments, include the following:

  • How does this disease disrupt normal body functioning (homeostasis)?
  • If you are commenting on a post that already has comments, be sure to include new information, don’t merely agree or restate your classmate’s comment.
