Impaction (animals)
Impaction is bowel obstruction that can occur in various kinds of animals when they consume something that they cannot digest. Once the substance is ingested it will block the digestive tract and, if untreated, cause death. Symptoms Some symptoms include a lack of appetite or lethargy. On many reptiles a large blue seemingly bruised spot will be visible in the abdomen; however, this only shows through if the skin on the species is clear enough to see the lower internal organs. Treatment Common treatments involve placing the reptile in a lukewarm bath and gently rubbing the area under the impaction to help the passing of the consumed substance. Place both thumbs on the back at the middle, put the first two fingers of the hand under the belly and rub gently in a circular way until the reptile defecates. If this fails, the animal must have an enema. See also * Aerosol impaction * Fecal impaction A fecal impaction is a solid, immobile bulk of feces that can develop in the rectum ...

Fecal Impaction
A fecal impaction is a solid, immobile bulk of feces that can develop in the rectum as a result of chronic constipation. A related term is fecal loading which refers to a large volume of stool in the rectum of any consistency. Fecal impaction is a common result of neurogenic bowel dysfunction and causes immense discomfort and pain. Treatment of fecal impaction includes laxatives, enema, and pulsed irrigation evacuation (PIE). Signs and symptoms Symptoms include chronic constipation. There can be fecal incontinence and paradoxical overflow diarrhea (encopresis) as liquid stool passes around the obstruction. Complications may include necrosis and ulcers of the rectal tissue. Abdominal pain and bloating could also be present depending on the severity of the condition. Loss of appetite can also occur. Causes There are many possible causes; for example, physical inactivity, not eating enough fiber, dehydration, and holding in bowel movements. Medications such as opioid pain relie ...

Dental Impaction
Impacted wisdom teeth is a condition where the third molars (wisdom teeth) are prevented from erupting into the mouth. This can be caused by a physical barrier, such as other teeth, or when the tooth is angled away from a vertical position. Completely unerupted wisdom teeth usually result in no symptoms, although they can sometimes develop cysts or neoplasms. Partially erupted wisdom teeth can develop cavities or pericoronitis. Removal of impacted wisdom teeth is advised in the case of certain pathologies, such as nonrestorable caries or cysts. Wisdom teeth likely become impacted because of the jaw being too small for the teeth to erupt well, probably caused by not chewing enough crunchy and hard foods such as fruits and vegetables in the years of physical growth. Impacted wisdom teeth are classified by their direction of impaction, their depth compared to the biting surface of adjacent teeth and the amount of the tooth's crown that extends through gum tissue or bone.

Aerosol Impaction
In the physics of aerosols, aerosol impaction is the process in which particles are removed from an air stream by forcing the gases to make a sharp bend. Particles above a certain size possess so much momentum that they can not follow the air stream and strike a collection surface, which is available for later analysis of mass and composition. Removal of particles from an air-stream by impaction followed by mass and composition analysis has always been a different approach as to filter sampling, yet has been little utilized for routine analysis because of lack of suitable analytical methods. Advantages The most clear and important advantage of impaction, as opposed to filtration, is that two key aerosol parameters, size and composition, can be simultaneously established. There are many advantages of impa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
