# non-SOP condition

Clinical onset

The time of clinical onset will be based on the history in the individual subject.  The condition is generally chronic, but there can be acute episodes and recurrent episodes.  An acute episode may be due to e.g. an irritant and may fully resolve.  In such a case, later episodes or the development of chronic symptoms (after a symptom free interval) may represent a new clinical onset.

Clinical worsening

Clinical worsening may be evidenced by an increase in chronic symptoms or in the extent of chronic inflammation evident on examination.
