Diagnosis
Classification
Sinusitis (or rhinosinusitis) is defined as an inflammation of the mucous membrane that lines the paranasal sinuses and is classified chronologically into several categories:
Acute sinusitis – A new infection that may last up to four weeks and can be subdivided symptomatically into severe and nonsevere. Some use definitions up to 12 weeks. Recurrent acute sinusitis – Four or more full episodes of acute sinusitis that occur within one year
Subacute sinusitis – An infection that lasts between four and 12 weeks, and represents a transition between acute and chronic infection. Chronic sinusitis – When the signs and symptoms last for more than 12 weeks. Acute exacerbation of chronic sinusitis – When the signs and symptoms of chronic sinusitis exacerbate, but return to baseline after treatment.Roughly 90% of adults have had sinusitis at some point in their lives. Acute
Health care providers distinguish bacterial and viral sinusitis by watchful waiting. If a person has had sinusitis for fewer than 10 days without the symptoms becoming worse, then the infection is presumed to be viral. When symptoms last more than 10 days or get worse in that time, then the infection is considered bacterial sinusitis. Pain in the teeth and bad breath are also more indicative of bacterial disease.Imaging by either X-ray, CT or MRI is generally not recommended unless complications develop. Pain caused by sinusitis is sometimes confused for pain caused by pulpitis (toothache) of the maxillary teeth, and vice versa.
Iridodonesis () is the vibration or agitated motion of the iris with eye movement. This may be caused by lens subluxation, the incomplete or partial dislocation of the lens; or by aphakia, the absence of a lens. The term originated from irido- (Latin: iris) + doneo (Greek: δονεο, to shake to and fro). See also
Phacodonesis
