Filter by:We plan to conduct a study, to see how safe and effective timolol maleate 0.5% gel-forming solution is for infantile hemangiomas (IH) and the response of hemangiomas to timolol maleate 0.5% . Our hypothesis is that timolol will inhibit and possibly reverse growth of appropriate infantile hemangiomas.
A combined set of quantitative skin imaging methods will quantitatively describe the natural ontogeny and the response to standard treatments over time in patients with infantile hemangiomas.
The purpose of this study is to investigate the pathogenic mechanisms of Port Wine Stain, collect biopsy samples and blood samples to characterize exosomes and metabolites from Port Wine Stain.
In this research study investigators want to learn more about capillary malformations which are also known as port wine stains. Investigators are asking children with capillary malformations (port wine stains) to be in the research, because investigators do not have a good idea of what to expect from the current treatments of these malformations. These malformations are treated with laser as clinically indicated and there are no standardized methods to assess improvement.
Port wine stains Birthmark are congenital, progressive vascular malformations of the skin that occur in approximately 0.7% of newborns. Approximately 1.5 million individuals in the United States and 32 million people worldwide have Port wine stains birthmarks. Two-thirds of these malformations occur on the face. Personality development of virtually all patients is adversely affected as a result of the negative reaction of others to a "marked" person. Detailed studies have documented lower self-esteem and difficulties with interpersonal interactions in Port wine stains patients. Port wine stains are initially flat and red, but with time, they tend to darken to purple and become thickened as vascular nodules develop. This thickening occurs in approximately two-thirds of lesions and further disfigures the facial features of many patients.
Port wine stain Birthmark is a congenital, progressive vascular malformation of human skin. However, even though the pulsed dye laser is considered as the treatment of choice for Port wine stain Birthmark the degree of fading can remain variable and unpredictable after laser treatment.
Port-wine stain is a congenital, progressive vascular malformation of human skin involving post-capillary venules that occurs in an estimated 0.3% of children and can alter personality development and psychological in children.
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.
There is no effective treatment for hemangioma regardless of immediate severity. That is in this respect a orphan disease. These hemangiomas, sometimes large, will have a phase of proliferation of several months (very scary for parents) and regression over several years. The natural history is peppered with local complications (ulcers) and aesthetic and psychological sequelae (sometimes major for the child and the family). The effects of acebutolol and propranolol on the proliferative hemangiomas were discovered accidentally by two French teams (Montpellier for acebutolol and Bordeaux for propranolol). Acebutolol and propranolol have been used for many years for the treatment of hypertension and congenital heart disease, including infants, with few side effects. The effects of acebutolol and propranolol were immediately visible with reduced volume and skin whitening of the hemangioma. In a preliminary study, acebutolol was administered to 20 patients in Montpellier with big regression of hemangiomas. The aim of the study was to compare the clinical efficacy of acebutolol (10mg/Kg/jour) and propranolol (3mg/Kg/j) on the proliferative phase of infantile hemangioma in infants.
The investigators hypothesize that there are differences between infantile hemangiomas (IH) during the proliferating and involuting phases and in response to medical treatment that can be detected by optical tomography of these hemangiomas.
