The Science of Arthritis

The Science of Arthritis
Adam Waxler

In order to understand how to handle arthritis pain, you need to understand how the body works and how arthritis can impede the body from working properly. Once someone has a general understanding of the science behind arthritis, one can better understand how to handle arthritis pain and get some arthritis relief.
First of all, there are several different types of arthritis. The two most commonly known forms of arthritis are osteoarthritis (OA) and rheumatoid arthritis (RA). However, there are three other major types of arthritis. These other forms of arthritis are systemic lupus erythematosis, ankylosing spondylitis and gout. Lets take a look at each:
Systemic Lupus Erythematosis (SLE) This form of arthritis mainly affects women. It develops in the skin, internal organs and joints.
Ankylosing Spondylitis This form or arthritis affects the spine and can also affect the ankles, knees, lungs, heart, shoulders and eyes.
Gout This is a painful affliction mainly for men, about one million of them in the United States alone. Uric acid build up, due to an internal chemical malfunction, forms crystals that get stuck in a joint, generally the big toe, and become inflamed.
Where two bones meet, called joints, are covered with cartilage, also known as gristle. This cartilage is sturdy, elastic, and spongy or compressible, and keeps the bones from moving against each other at the joint. Healthy joints can handle some fairly heavy pressure. For example, when taking a walk a persons knees handle a force of three to four times a persons total body weight, while deep knee bends can increase to nine times the bodys weight. Unfortunately, arthritis effects how joints function properly in your body.
Surrounding the bones and cartilage is a strong, fibrous capsule lined with synovium, a thin membrane that lubricates the joint area with fluid. The end result is less friction or smoother rubbing together of the bones. This fluid also feeds the cartilage cells, keeping them healthy, and is pumped into them during joint movement. Therefore, lack of movement can be unhealthy. By understanding more about how joints work it is easy to see why exercise plays a crucial role in arthritis relief.
Arthritic joints can be affected with inflammation when bacteria or a virus (or other undesirable element) enters the joint area or when an injury occurs. What happens is when foreign matter enters this area or the area sustains injury, white blood cells, antibodies and other natural fighting mechanisms automatically kick in internally to help. These fighters cause swelling, redness and heat as the body fluid moves around. Symptoms of inflammation, one of the uncomfortable issues associated with arthritis pain, are redness, swelling and tender joints.
The exact science of what actually causes arthritis is still being researched. For most forms of arthritis, the causes are unknown. Injury, overuse of joints and mechanical issues with joints (like skeletal abnormalities, worn out joint muscles) can lead to arthritis. Many arthritis experts also point to issues relating to bacteria as one of the main culprits causing arthritis. Heredity, stress, drugs, food allergies and viruses have also been linked to some forms of arthritis. Likewise, diet, poor circulation, and lack of movement have also been connected to arthritis.
While it appears that arthritis may be caused by many factors, the good news is that at least some of these factors can be controlled. Clearly, a healthy diet and plenty of exercise will go along way towards arthritis relief.

Food Allergies in Kids

Food allergies are a common problem in kids. Nearly two million children have food allergies in the United States. Some food allergies are life threatening, even if the food is taken in very little quantity. Peanut tops the list of notorious foods which cause allergies. Following it are milk, especially cows milk, soy, eggs, wheat, seafood and other nuts.

Food allergies are caused when the immune system is confused. The job of the immune system is to protect the body from diseases, bacteria, viruses and germs. The antibodies produced by the immune system helps to fight these minute external organisms which makes the person sick. But if the body is allergic to certain food, the immune system mistakes the food to a harmful foreign substance and takes action towards it thinking that it is dangerous to the body. The body acts adversely, when it isnt supposed to do so.

When the immune system detects allergic substance, the antibodies produce mast cells. They are a kind of immune system cell which release a chemicals, such as histamine, in the bloodstream. These chemicals affect the respiratory system, digestive system, nose, eyes, throat, and skin. Initial symptoms are runny nose, tingling sensation in the lips or tongue, and itchy skin rash like hives. The reaction can be mild to severe and depends on every individual. The symptoms can appear right after the food is consumed or after few hours. Other symptoms are cough, wheezing, nausea, hoarse voice, vomiting, diarrhea, stomach ache, and throat tightness.

A sudden and harsh allergic reaction is known as anaphylaxis. The patient encounters many problems, all at once which involve blood vessels, the heart, digestion, breathing, and skin. The blood pressure drops very steeply, the tongue swells and there is swelling in the breathing tubes. Patients who have such allergic reactions should be ready to handle emergencies. They should always carry some type of medicine which will help to combat or reduce the adverse affect of the food.

Most of the times, it is very easy to detect the cause of food allergy. Problems such as hives begin to surface as soon as the child eats the substance he is allergic to. At other times, it becomes very difficult to determine the cause of allergy. In such cases, everything should be observed under close surveillance. Food items which are made out of many ingredients should be thoroughly checked for the allergic cause. Most of the times, allergies are inherited from other family members or other kids born with food allergies. Changes in the surroundings and the body play a major role in these kinds of cases. Some of the kids arent actually allergic to the food and show only mild reaction. Like people who are lactose intolerant suffer from diarrhea and belly pain after consuming milk and diary products. This is not an indication that the child is allergic to milk. This reaction happens because their body is incapable of breaking down the sugars which are found in diary products and milk.

If the conditions are severe, a doctor should be consulted immediately. If food allergy is diagnosed, the doctor refers to an allergy specialist. The doctor asks questions like eating patterns, past allergic reactions and the time period between the consumption of food and the surfacing of the symptoms. The specialist can also ask about allergy related conditions like asthma or eczema and whether allergic reactions are hereditary. Usually skin test and blood test is done to test the antibodies and the reaction they have on the skin when it is exposed to the allergic substance.

Kids who are allergic to egg and milk outgrow them as the age progresses. But allergies which are severe and are related to items such as peanut, shrimps, and some kind of fish, last for a lifetime. Other than food, children can be allergic to certain medicines and flower pollen. The best way to avoid allergies is to avoid the cause of it. No specific medicine has been developed for the cure of allergies.

Flu and Cold in Children

Flu and cold usually accompany each other when attacking a childs immune system. It is a wide spread viral infection and the harsh truth is that there is no permanent treatment designed for it because of the involvement of many types of viruses which cannot be killed, but yes their growth rate can be suppressed. Symptomatic treatments can trigger the rate of improvement in the childs health, but it might not work for all kids.

The child can get affected by the flu and cold virus when he is exposed to an infected person. The symptoms are mild headache, feeling of tiredness, stuffy or runny nose, watery eyes, light fever, sneezing, cough, muscle aches, and sore throat. It takes two to five days for the symptoms to appear and three to five days for the complete development of the virus. It takes nearly two weeks to completely get rid of the flu. The virus attacks the upper respiratory system. These are the symptoms of cold. The symptoms of flu are more terrible than cold and grow very rapidly. They are high fever, runny nose, sore throat, nasal congestion, chills, fatigue and nausea, vomiting, eye pain and extreme headache. Symptoms are extremely important when trying to differentiate between flu and a cold. As stated before, the symptoms of flu are more severe when compared to the symptoms of cold. Also, it is easier to get over cold than flu. The biggest clue will be recalling any incident of exposure to patients having either flu or cold. Even after thorough analysis, if it is difficult to reach any clear conclusion, a doctor should be consulted. A swab is taken from the nasal track or throat and the results are determined an hour after the test is taken.

No antibiotics work on these viruses. Intake of antibiotics cannot better the condition in any way whatsoever. Also, there are chances of secondary bacterial infections like sinus or ear infection. The child should be administered with fluids and a cool mist humidifier to suppress the symptoms and to help him feel better. Medications are available over the counter which can be bought depending on the symptoms of the infected. Antiviral medicines are available for the treatment of flu, which hasten the recovery process. But the medicines are effective only when given within forty eight hours after the onset of flu symptoms. Runny nose, especially of infants and kids who cannot blow their nose, can be taken care of with the help of a bulb syringe or nasal drop. If flu isnt treated at the right time, it can worsen the health of the infected and can also lead to pneumonia.

Flu is a very commonly spreading infection among school going kids. According to a research, nearly twenty percent of Americans are infected with flu every year and nearly twenty thousand people die because of it. The only way to prevent the child from contracting these virus is by getting him/her a flu shot before the flu season or as recommended by the physician. The vaccine is either administered through a shot or nasal spray. Regular dosage will strengthen the immune system by constructing antibodies. The nasal spray vaccine contains live weakened viruses and shots contain completely dead viruses. By any chance, if the child does get exposed to the virus, he/she should be given medicine meant for flu patients, immediately. More than hundred viruses are known which cause cold. A lesser number of viruses are known to causes flu. That is the reason why there is a shot for flu and not cold.

But flu shot cannot be taken by anyone or everyone. People who complain of allergic reactions from previous flu shots, people who have the Guillain-Barre syndrome and people allergic to eggs are not eligible for flu shots. It is highly recommended to take advice from a physician before getting vaccinated. Children and elderly should be given nasal spray vaccination, but instead they should opt for flu shots. Out of total population, there are certain people who have a greater probability of getting flu. Children up to five years of age, elders older than sixty five years, nursing home residents, pregnant women, patients with long term problems regarding health, and health care workers who come directly in contact with flu patients.

Rheumatoid Arthritis

Rheumatoid Arthritis
Charlene J. Nuble

A shooting pain in the knee. A burning sensation in the hand. Before you know it, you have rheumatoid arthritis. Rheumatoid arthritis is a chronic inflammation of the joints. Rheumatoid arthritis is an autoimmune disease in which the immune system attacks normal tissues as if they were invading antibodies. Rheumatoid arthritis also causes inflammation of the tissues around the joints and other organs of the body. The hands and feet are the most affected areas of rheumatoid arthritis although it can also affect any joint lined by a membrane. Rheumatoid arthritis is referred to as a systematic illness and sometimes called rheumatoid disease.Rheumatoid arthritis manifests itself over a period of a few months. However, for some, the disease appears overnight. Accelerated onset of rheumatoid arthritis does not mean the individual is at greater risk of the progression of the disease. Rheumatoid arthritis can lasts for years without symptoms. But rheumatoid arthritis is an illness that progresses and has the potential to cause joint destrution and functional disability. Usually, patients suffer cycles from severe to light symptoms. In terms of statistics, rheumatoid arthritis is three times more common in women than in men. It also besets people of all races equally. Rheumatoid arthritis can begin at any age but most often start in the early forties. What causes rheumatoid arthritis? The truth is, its cause is still unknown. Viruses, bacteria, and fungi have long been suspected but none has been proven to be the cause. The cause of rheumatoid arthritis has been the focus of different research activities. There are some scientists who believe that the tendency to develop rheumatoid arthritis may be genetically inherited while others believe that certain factors in the environment might elicit the immune system to attack the body’s own tissue components. This attack results to the inflammation in various organs such as lungs or eyes. Researchers have also found that environmental factors may also play a role in the cause of rheumatoid arthritis. In fact, scientists reported that smoking tobacco increases risk in the development of rheumatoid arthritis.The symptoms of rheumatoid arthritis depend on the degree of tissue inflammation. Rheumatoid arthritis is said to be active if the body tissues are inflammed. When the tissue inflammation subsides, rheumatoid arthritis is said to be in remission. Remissions may happen spontaneously or with treatment and can last for weeks, months, even years. During active rheumatoid arthritis, symptoms are felt. Symptoms may include fatigue, lack of appetite, low grade fever, and muscles and joint aches. Muscles and joint stiffness are usually felt during mornings and after a period of inactivity. During relapses (from inactivity to activity) of rheumatoid arthritis, joints become red, swollen, painful, and tender. This happens because the tissue lining of the joints become inflamed which results in the excess production of joint fluids. Multiple joints are usually inflamed in symmetrical pattern and the joints of both hands and wrists are often affected. Simple tasks such as turning the door knob and opening the jars can be painful. Rheumatoid arthritis can also affect the joint responsible for the tightening of vocal cords to change the tone of the voice although rarely. But when this happens, it can cause hoarseness of the voice. As mentioned before, rheumatoid arthritis is a systematic disease which can affect organs and areas of the body other than the joints. Sjorgen’s syndrome is the inflammation of the glands of the eyes and mouth which causes dryness. Rheumatoid inflammation of the lung lining can cause chest pains because the lung tissue itself is inflamed and nodules of inflammation also develop within the lungs. Rheumatoid arthritis can also reduce the number of red blood cells which can result to anemia and white blood cells which can result to increase risk of infections. A rare, serious complication of rheumatoid arthritis is blood vessel inflammation which can impair blood supply to tissues and lead to death of tissues. A rheumatologist is a doctor who specializes in arthritis and other related diseases. The rheumatologist reviews the history of symptoms, examines the joints, and the other parts of the body for the inflammation. The diagnosis is usually based on the pattern of symptoms, the distribution of the inflamed joints, and the blood and x-rays obtained. Until now, there is no known cure for rheumatoid arthritis. Reducing joint inflammation and pain, maximizing joint function, and preventing joint destruction is the current goal in treating rheumatoid arthritis. Early medical intervention has been found to improve outcomes in treatment. Optimal treatment includes combination of medications, joint strengthening exercises, joint protection, and patient education. Treatment is customized according to many factors such as disease activity, types of joints involved, general health, age, and occupation. But treatment is most successful when there is close cooperation between the doctor and the patient.————————-Note: This article may be freely reproduced as long as the AUTHOR’S resource box at the bottom of this article is included and and all links must be Active/Linkable with no syntax changes.————————- About the Author
