Active clinical trials for "Port-Wine Stain"

The purpose of this study is to assess the safety and efficacy of Timolol Maleate treatment for different depth of infantile hemangioma based on B-ultrasonography. Based on the depth of hemangioma, patients will be proactively allocated to two groups. And then, all patients in both groups will receive topical timolol treatment in the same protocol and dosage.

Based on the Doppler effect, Laser Doppler Imaging (LDI) uses the interaction of light with moving erythrocytes to visualize perfusion in the microcirculatory system. The new device to be used in this study have been adapted specifically for the application, facilitating its use in clinic. It has been designed to take a standard white light image of the area under inspection simultaneously with the perfusion image to facilitate clinical assessment. Port-wine stain (PWS) birthmarks are congenital, low-flow vascular malformations of the skin found in approximately 0.3% of children. They are commonly found on the face and neck and may cause serious psychological consequences. Lasers are the modality of choice for the treatment of PWS birthmarks. The use of PDL is very effective in PWS in closing the blood vessels and diminishing therefore the redness of the skin. Repeated laser treatment is necessary to achieve the desired clinical outcome. Actually, the efficacy of the treatment of PWS by the laser is obtained by clinical inspection and digital photography. By measuring the activity and intensity of the microcirculation present in and under the skin, the Laser-Doppler (LDI) will be capable of measuring the effect of Pulsed dye laser (PDL) treatment for port-wine stains.

This is a pilot exploratory study. The goal of this study is to evaluate a new imaging tool, optical frequency domain imaging (OFDI), to reveal the microvascular morphology of capillary malformations.

The purpose of this study is to evaluate the genotype of CTCF, a proven transcription factor, in patients with infantile hemangiomas and to monitor tumor growth. The investigators aim to determine whether or not the CTCF genotype might serve as an early and reliable predictor of tumor growth.

Infant hemangioma(IH) is the most common benign vascular tumor of infancy with the estimated incidence varies 1% to 12%.However, in China, the incidence of infant hemangioma and related epidemiological data remains unclear. So, the investigators designed the study for the following purposes: 1, to aware the incidence of infantile hemangioma and understand the related risk factorsin China; 2, to understand the clinical characteristics of infantile hemangioma and the risk factors for complications; 3, to investigate the level of knowledge, treatment options in infant hemangioma in Chinese doctors; 3, to improve the awareness of infantile hemangioma in parents and provide more advice for pregnancy counseling and eugenics.
