Active clinical trials for "Port-Wine Stain"

Port wine stain (PWS) is a congenital, progressive vascular malformation of human skin involving the superficial vascular plexus that occurs in estimated 3-5 children per 1,000 live births. In childhood, PWS are 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. Because most malformations occur on the face, PWS is a clinically significant problem in the majority of patients. The late-stage cobblestoning appearance of PWS subjects is comprised by not only pronounced vascular ectasia with proliferation of thin and/or thick-walled vessels and their stroma, but also numerous epithelial, neural and mesenchymal hamartomatous abnormalities. Despite these histologic observations, the specific mechanisms involved in PWS nodular formation remains unclear. In one nodular PWS subject, we found that phosphatidylinositol 3-kinases (PI3K)/protein kinase B (AKT) and phosphoinositide phospholipase C g subunit (PLC-g) were activated in both hypertrophic areas and nodules within the lesion. These observations led us to hypothesize that the PI3K pathway may play an important role in nodular formation.

Through this study, the investigators shall compare the effectiveness of atenolol with propranolol in the treatment of IH. In addition, the investigators shall try to elucidate the mechanism of action of beta blockers by assessing their action on triggers such as hypoxia. The study design will be a parallel group comparative study wherein patients of IH will be randomized into two groups. One group will receive propranolol and the other atenolol for a maximum period of 9 months. The patients will then be followed up regularly for regression of the IH based on Physician global assessment, hemangioma activity score(HAS), serial photography and lesional ultrasonography. Any side effects encountered during the treatment period will also be noted. Also serial measurements of hypoxia inducible factor 1 alpha(HIF-1α) will be made to ascertain the mechanism of action of the drugs.

Is to compare and evaluate the efficacy of oral captopril with oral propranolol, intralesional propranolol injection, and topical Timolol in the treatment of infantile hemangioma and their effect on vascular endothelial growth factor and CD 133.

Port-wine stain (PWS) is a congenital capillary malformation with an incidence of 3-5/1000 newborns and grows commensurately with the affected individual. Although PDL treatment can significantly lighten and reduce most PWS lesions, 20% of cases show little improvement after treatment. Our previous researches suggested that PDT may be a beneficial option for PWS cases that are resistant to multiple PDL treatments. In this study, a single center, prospective, parallelled, controlled study was conducted to compare the efficacy of PDT on PWS treated with standard PDL and those without any treatment.

Pulsed dye laser (PDL)is the gold standard treatment of port wine stains (PWS). However, many sessions are required and failure or relapses are not uncommon. It has been demonstrated that a neoangiogenesis occurs after PDL, explaining at least partially those failure. The objective of this study is to evaluate the use of a topical beta-blocker (timolol 1% gel) as a combination treatment with PDL for treating PWS. Methods. Prospective multicenter study comparing PDL alone to PDL + timolol. Sessions of PDL will be performed once a month for 3 months. One group will be treated with PDL alone and the other will also applied timolol 1% gel twice a day during treatment. The evaluation will be done one month after the third session.

Port Wine Stain on a limb can be either isolated or associated with complications (venous or orthopedic impairment, arteriovenous malformations), leading sometimes to complex syndromes (Klippel-Trenaunay syndrome,Parkes-Weber syndrome). Little is known about epidemiology of port wine stains: their evolution during the growth of the child, the frequency of complications, genetic data, and prognostic factors. This prospective french national cohort will help for : description of the evolution of port wine stain and possible complications; prognostic factors for complications ; association with mutations of RASA1 gene; quality of life of these children. It will also help for global appreciation of the management of this disease in France.

The Intense Pulsed Light (IPL) technology, by selective phototermolysis, is used for eliminating, among other application, benign vascular lesions and unwanted leg veins. Light energy heats the deeper structures of the skin. IPL devices provide a broad wavelength spectrum of 515 to 1200 nm and fluence from 10 to 40 J/cm at o.5-1 Hz.The light is focused by a reflector and then transmitted through various filters that cut off the lower wavelength range of the emitted light; therefore, only those wavelengths longer than these of the filters are transmitted. objectives: evaluate and optimize the clinical performance of the Luminis ONE platform for each of the aforementioned clinical applications. Reconfirm the parameter settings for each of the aforementioned clinical applications. Confirm the user friendly design of the device, in aspects of software (user interface) and various technical operational features.

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.

Infantile hemangioma is a benign tumor belonging to the group of vascular tumors in the ISSVA classification (International Society for the Study of Vascular Anomalies). The diagnosis is clinical and radiological. The hemangioma appears during the first weeks of life (70% classically within 2 weeks after birth) but can, when it develops in the subcutaneous tissue, appear until the age of 2 to 3 months . Its evolution is characteristic and is divided into 3 phases with a proliferative phase characterized by a rapid increase in the size of the tumor (up to 6 to 12 months), a phase of stabilization (from 12 to 36 months) with a stopping of the growth of the hemangioma and a regression of its size and a phase of involution with the disappearance of the lesion which may give way to residual fibroadipose tissue, cutaneous telangiectases, scars … The usual complications of haemangiomas occur during the proliferative phase. It is necrosis, ulcerations that can be complicated by bleeding or infection and eventually indelible scarring. Other complications related to the site of development of hemangiomas (amblyopia, astigmatism, upper respiratory obstruction, nasal obstruction, sphincter disorders, eating disorders), hemangiomas destroying structures noble (breast hypodévelopment, alopecia). The aesthetic prognosis can be seriously compromised for facial locations. Historically, when drug therapy was required, patient management was based on systemic corticosteroids (at doses of 3 to 5 mg / kg / day) in first-line therapy and vincristine as a second-line failure of corticosteroid therapy or when life-threatening is at stake. In 2014, the high French health authority (HAS) gave Marketing Authorization for Hemangiol 3.75 mg / ml oral solution for the management of infantile proliferative hemangioma requiring first-line systemic treatment, evaluating the actual benefit as important. The selected indication concerns children from 5 weeks to 5 months with: Hemangiomas leading to a vital or functional risk, Hemangiomas ulcerated painful and / or not responding to simple care, Hemangiomas with a risk of permanent scarring or disfigurement. The 2014 HAS Transparency Commission wishes in its report "to have follow-up data of prescriptions allowing to describe on a representative sample of patients, the characteristics of the treated patients, the indication, the doses and the durations of treatment of this specialty ". The objective of our study is to describe the use of Hemangiol in current practice in our hospital from 2014 to 2018.
