Hemangioma
Conditions
Brief summary
Infantile hemangioma (IH) is the most common benign vascular tumor in pediatric population. The characteristic natural history of this tumor is rapid growth in the first year of life and follows by spontaneous involution. However, it may cause cosmetic unacceptable. Early intervention in superficial IH may help to minimize the risk of residual aesthetic problems. Topical timolol, a non selective beta-blocker, is an emerging treatment which has been reported in efficacy and safety for the treatment of IH. However, the reported studies were case-series or small study. This study is a prospective double-blind,randomized-controlled study to evaluate the efficacy and safety of 0.5% timolol maleate solution for treatment in superficial IH. The patient will be treated with topical timolol for at least 6 months and instructed to 4 times daily apply 1-2 drop of timolol solution on the lesion and rub over the entire lesion with a finger. Photographs of the lesion will be taken at the baseline and every 1-month visit. Clinical evaluation of the treatment efficacy is carried out by 2 investigators independently to determine the change in lesion size and visual analogue scale of the lesion color. The main outcome is to evaluate the efficacy of 0.5% timolol maleate solution in treatment of infantile hemangioma compared to placebo.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Efficacy of the topical 0.5% timolol maleate solution in treatment of infantile hemangioma compared to placebo | 6 months | Percent changes in visual analogue scale of the lesion color and global assessment scale of the lesion after treatment |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Side effects of the topical 0.5% timolol maleate solution in treatment of infantile hemangioma | 6 months | The side effects of 0.5% timolol maleate solution include bradycardia, dizziness, irritant contact dermatitis, allergic contact dermatitis, fatigue, nausea, diarrhea,and insomnia. To determine the side effects, investigators will monitor the vital signs of the patients every follow-up visit and ask the caretakers about the side effects. Furthermore, every patients will receive the dairy to record the frequency of drug usage and side effects found. |
