Sprain - Wikipedia, the free encyclopedia

A sprain is an injury in a joint, caused by the ligament being stretched beyond its own capacity. A muscular tear caused in the same manner is referred to as a strain. In cases where either ligament or muscle tissue is torn, immobilization and surgical repair may be necessary. Ligaments are tough, fibrous tissues that connect bones to other bones. Sprains can occur in any joint but are most common in the ankle and wrist.[1]

The diagnosis of a sprain injury is made by a physical examination. In most cases an x-ray (or stress x-ray) of the affected joint is obtained to ensure that there are no fractures. If a tear in the ligament is suspected, then an MRI or arthroscopy is obtained. MRI is usually ordered after swelling has subsided and can readily identify the presence of a ligament injury.[2]

Sprains typically occur when the joint is overextended. This can cause over stretching of the joints, tear or slipping of the ligament.[3]

lane suchy's insight:

Overview: a sprain is an injury to the joint, it is caused by a ligement being stretched beyond its capacity. Ligements are tough fiberouse muscle tiddues that connect bone to other bones and when these ligements are stretched too far the result is a sprain. a sprain can occur in any joint in the body where a ligement is present, but they are most common in the ankle and wrist. Sprains are broken up into three different degrees. there is a first degree sprain which is a tear of only a few fibers in the ligement, a second degree srain which is a tear of a part of the ligement, lastlty there is a third degree sprain which results in a complete tear of the ligement. A sprain is more likely to occure when there are certain factors involved. for example muscle fatigue can increase the risk of a sprain, or a sprain has a higher chance of happening when there is no stretching to a muscle before the muscle is worked.

 

Signs and symptoms: A sign that a sprain has occured includes a sharp pain, dark bruising to the area, a popping sound which occurs from the torn ligements, swelling to the effected area, decreased ability to move the limb, and difficulty moverability.

 

Treatment: to treat a sprain you must follow the RICE rule. RICE stands for rest,ice,compression, and elevation. first you must rest the sprain and keep from using the effected area as much as possible, then ice simply put some ice on the sprain this will take down the swelling and will mask some of the pain, next compression you must bandage the sprain or in etreme cases a cast will be nescesary, finally elevation, it is good to keep the sprain elevated this will also help take down swelling.

 

Prevention: sprains can occur at any time and there is not alot of ways from preventing them. one could simply slip and sprain there ankle or fall down and sprain thier wrist. although stretching your muscles and keeping fit are good ways to prevent a sprain.

 

Fun Facts: Sprains can occur at any joint n the body!!!! this can include, fingers, toes, wrist,and ankles.

What Is Asthma? - NHLBI, NIH | the creation of scoopit | Scoop.it
lane suchy's insight:

Overview:asthma is a lung disease that affects all ages but most offten ages 7 to 25. People with asthma ave inflamed airways which makes the airways react to certain inhaled objects.when the airways are irritated they will constrict which causes a wheezing sound when the person with asthma breathes, and makes it harder to breathe. When the airways are irritated the cells in airways start to produce more mucus which furthur causes irritation and harder breathing. the result from all this is asthma symptoms. Asthma symtoms will often go away with medication or after a period of time but sometimes the symptoms worsen causing an asthma attack. Attacks can be fatal and require emergency care to help, results from an attack can include siezures or blackouts. Asthma has no cure and when infected asthma can be trigured at any time. However with todays knowledge it has become easy to manage the disease with variouse medications. when infected with asthma you should have knowledge of all the signs and preventions.

 

Signs: signs include wheezing, coughing, and chest tightness.

 

Preventions: when you notice these signs you are able to prevent it with inhalers or "puffers" carrying ventalin or advaire. or by even just learning what irritates your lungs and staying away from it.

 

Interesting facts: In the United States more than 25 million people are known to have asthma, and over 7 million of these people are children.
