Lasers are being used to treat Port Wine Stains (PWS), but the laser doesn't always work. Only about 10% of PWS can be completely cleared. The research team believes that the investigators can improve the response of PWS to laser therapy by using a computer program that the principal investigator of this study (Dr. Shafirstein PhD) has developed. The purpose of this study is to test the validity of this computer program. Personalized Interactive Laser Therapy (PILT) could significantly improve clinical outcomes of laser treatment of PWS.
The investigators observed that Propranolol, a beta-blocker commonly used in children was efficient to control the growth of alarming hemangiomas of the face. The primary objective of this study is to determine the efficiency of 1 month-early treatment of propranolol in infants aged less than 4 months affected by an hemangioma without any consequences on vital or functional structure and not justifying corticosteroids. The secondary objectives are: - the kinetic of the hemangioma evolution in infants treated by propranolol - Observance - Safety
The purpose of this study is to improve port wine stain therapeutic outcome in response to laser therapy. The researcher want to determine whether the combined use of pulsed dye laser therapy and topical ranibizumab will improve port wine stain therapeutic outcome.
Hemangiomas of infancy, the most common benign tumors of infancy, are congenital or early infancy lesions characterized by a rapid postnatal growth, with high expression of angiogenic stimulators for 9-18 months, followed by slow regression for 5-9 years. Current therapies for the hemangiomas are usually restricted to more severe forms due to the risks of adverse effects, inconvenience and cost. Nevertheless, a substantial amount of the psychological discomfort and morbidity can be caused by untreated hemangiomas, especially those in the face. Recently, Imiquimod 5% cream has emerged as a safe an effective drug for several skin conditions that benefit from modulation of the activity of the immune system, such as common warts and various forms of the skin pre-cancerous and cancerous lesions. Small case reports series have suggest that it could also be useful in hemangiomas, possibly through the inhibition of the angiogenesis by local IFN production.This is a small, open label study of 16 patients to document the efficacy of the Imiquimod 5% cream in the treatment of hemangioma of infancy (primary outcome). IFN and plasma drug levels, as well as clinical examinations and blood studies, will be carried out to evaluate safety of the treatment (secondary outcome). bFGF and VEGF will be measured in blood and urine in order to study the diagnostic and predictive value of these pro-angiogenic factors in the response of hemangiomas to the treatment with Imiquimod (secondary outcome). The study is a phase II clinical trial of a once a day application of Imiquimod 5% cream, 3 to 7 times per week for a maximum of four months. The study held at the Dermatology Clinic of Sainte-Justine Hospital, and was completed within a 20 months timeframe after IRB approval.
Port wine stains are red birthmarks that without treatment persist for a lifetime. They are frequently found on the face and can be conspicuous and disfiguring, negatively impacting social interactions for these patients. Treating Port wine stains is difficult. The standard of care is to use laser treatment, but over 80% of patients fail to completely clear despite multiple treatments. The growth of additional blood vessels (angiogenesis) following the Laser treatment is likely an important factor in why these lesions persist despite therapy.
Port wine stain is a congenital, progressive vascular malformation of skin involving post-capillary venules that occurs in an estimated 4 children per 1,000 live births. Approximately 1,200,000 individuals in the United States and twenty-six million people worldwide have Port wine stain birthmarks. Since most of the malformations occur on the face, Port wine stain is a clinically significant problem in the majority of patients. Port wine stain should not be considered a cosmetic problem but a disease with potentially devastating psychological and physical complications. Personality development is adversely influenced in virtually all patients by the negative reaction of others to a "marked" person. Port wine stain are initially flat red macules, but lesions tend to darken progressively to purple, and by middle age, often become raised as a result of the development of vascular nodules. Hypertrophy of underlying soft tissue further disfigures the facial features of many patients.
The research hypothesis is that topical application of a mixture of pre-polymers of polypropylene glycol and polyethylene glycol (an optical clearing agent) will reduce skin light scattering, increasing the amount of light reaching the target for diagnostic as well as therapeutic purposes.
Port wine stain are a congenital, progressive vascular malformation of human skin. The pulsed dye laser is approved by the Food and Drug Administration for the treatment of choice. However, the degree of port wine stain blanching seen following pulsed dye laser treatment remains variable and unpredictable. If the ultimate standard required is complete lesion blanching, the average success rate is below 10%, even after undergoing numerous pulsed dye laser treatments. Moreover, less than 50% of patients achieve 50% fading of their Port wine stain in response to pulsed dye laser therapy.
This research study was designed to determine the effect on port wine stains (PWS) of liposomal benzoporphyrin derivative monoacid (BPD-MA) termed verteporfin by intravenous (IV) infusion for photodynamic therapy (PDT) or combined PDT and pulsed dye laser (PDL) therapy (PDT + PDL). The standard treatment for PWS is PDL alone. This lightens some PWS but many lesions are not completely removed. PDT uses a medication and light together to cause injury to a target. The medication is given and then light is directed at the desired area of treatment to achieve an effect. PDT has been used to treat some skin conditions including pre-cancers and skin cancers. Using PDT or PDT immediately followed by PDL therapy may improve PWS lightening. At this time, both PDT and PDT + PDL therapy for treatment of PWS is investigational. The type and amount of medication and light which may be used to treat PWS is not known, and is likely to be different than those used for other PDT treatments.
