Filter by:This is retrospective study. The patients treated with oral propranolol at a dose of 2.0 mg/kg per day. Growth parameters (height and weight) were measured at the beginning, the end of treatment and 2 years after treatment. The weight-for-age Z-score (WAZ), height-for-age Z-score (HAZ) and weight-for-height Z-score (WHZ) calculated by the WHO Anthro software were used to assess physical development, and the WHO Child Growth Standards were used as the standards.
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.
The purpose of this study is to obtain information (such as lesion depth, depth of the most superficial part of the lesion, and the size and density of blood vessels) with the assistance of an imaging device, and use this information to assist in selection of laser settings for the treatment of skin conditions. The imaging modality is called Optical Coherence Tomography (OCT). Multiple laser modalities will be used, including intense pulsed light lasers (BroadBand Light, Profractional Sciton), pulsed dye lasers (Vbeam Perfecta, Candela), long-pulse 755nm lasers (GentleLASE, Candela), Sciton long-pulse 1064nm lasers, and non-ablative and ablative fractional resurfacing lasers (Profractional, Sciton). All of the lasers noted above are the only ones that will be used in this study. These lasers have 510k clearance and are being used as per their approved indications in this study. The choice of laser type is based on the skin lesion and is recommended by the physician, and the subjects who are going to enroll in this study will already be planned to undergo laser treatment as a standard of care for their condition. This is a pilot study that will explore the utility of skin imaging in guiding the laser treatment of skin lesions.
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.
This pilot study aims to evaluate the safety and efficacy of hemoporfin photodynamic therapy (PDT) with different light doses for port-wine stain (PWS）in 2-7 years old children. The pharmacokinetic behavior and pharmacokinetic parameters of hemoporfin in children will be investigated as well.
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.
Two limitations of single pulse, laser treatment of port-wine stains (PWS) are: (i) hemorrhage and purpura which may lead to post-treatment pigmentation and (ii) the necessity for repeated treatment sessions. In contrast, multiple pulses induce summation of irreversible, thermal injury from a series of lower-peak temperature heating cycles and may therefore reduce mechanical injury while preserving the selectivity of photothermal injury. Ideally, hemorrhage could be prevented and the efficiency of vessel closure could be greater. A clinical and histological pilot study of 10 adults with either facial or non-facial PWS is therefore proposed here.
1. 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. 2. 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. 3. 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.
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.
The primary purpose of this study is to identify the clinical characteristics of infantile hemangioma (IH) in our single center in China. The second objective of the study is to identify the clinical features of infantile hepatic hemangioma (IHH) and ulceration in patients with IHs.
