BACKGROUND: The prognosis of spontaneous @entity110 in association with early treatment remains unclear. In this study, we retrospectively studied the prognosis of acute spontaneous @entity110 in relation to age and treatments in a local clinic of dermatology. METHODS: Out of 5000 @entity1 who visited an office dermatology clinic, clinical records of @entity1 with spontaneous @entity110 were extracted. Their prognosis and the relation to age and treatments were analyzed by the Kaplan-Meier method and generalized Wilcoxon test. RESULTS: Among 386 @entity1 diagnosed with spontaneous @entity110 , 284 @entity1 (73.6%) began treatments within a week after the onset. Their non-remission rates after one week, four weeks and one year from the onset were 26.8%, 15.0% and 6.7%, respectively. The non-remission rates of @entity1 who were 20-years-old or younger by one year after the onset of @entity110 , were significantly lower than those of @entity1 older than 20-years-old. No apparent relationship between remission rates and sex or the use of @entity230 was detected. However, the non-remission rates of @entity110 treated with a standard dose of @entity16206 were lower than that treated with additional medications. CONCLUSIONS: Most @entity1 who began treatments within one week from the onset remitted quickly. However approximately 7% of them continued to suffer from symptoms for more than a year. Such prolongation tended to be seen among @entity1 who required other medications in addition to a standard dose of @entity16206 .
