Tolerability of 532 nm Laser Treatment of Port Wine Stains
Port-Wine StainThe goal of this study is to learn about treatment of port wine birthmarks treated with an FDA-approved 532 nm laser. The main questions it aims to answer are: How well are the treatments tolerated? Are there differences in tolerability of the treatment when a single high fluence laser pulse is used (the standard treatment) versus using multiple low fluence pulses? Are there differences in results when using a single high fluence pulse versus multiple low fluence pulses? type of study: Clinical Trial Participants will undergo 3 monthly laser treatments with the 532 nm DermaV laser. Part of their birthmark will be treated with the standard single-pulse high fluence approach, and other parts will be treated with the multiple-pulse low fluence approach.
KTP Laser vs Pulsed Dye Laser for Port-Wine Stains
Port-Wine StainTo compare the efficacy and safety of 532nm KTP laser and 585 nm pulsed dye laser for treating port-wine stains.
Assessing the Impact of Dosage Frequency of Propranolol on Sleep Patterns in Patients With Infantile...
Infantile HemangiomaThe purpose of this study is to assess the baseline sleep pattern disruption for patients starting oral propranolol at the standard BID dosing regimen compared to the control (timolol) group and to determine if there is a significant improvement in the sleep patterns in infants taking oral propranolol on the TID dosing regimen versus the control (timolol) group
Postmarketing Safety Study of Hemoporfin in Patients With Port Wine Stain
Port-Wine StainThis study is to provide safety information of hemoporfin during the post-marketing period as required by China Food and Drug Administration (CFDA) regulations in order to identify any potential drug related treatment factors in the Chinese population, such as unknown/unexpected adverse reactions, the incidence of adverse reactions under the routine drug uses.
A Pilot Study of Hemoporfin PDT in Children(2-7 Years Old) With Port-wine Stain
Port-wine StainThis 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.
Computer Aided Tool for Diagnosis of Neck Masses in Children
Neck MassThyroglossal Duct Cysts4 moreThe aim of this study was to evaluate the diagnostic efficacy of computer aided diagnostic tool for neck masses using machine learning and deep learning techniques on clinical information and radiological images in children.
A Study to Evaluate Efficacy and Safety of Light Dose in Subjects With PWB Treated With Hemoporfin...
Port-wine BirthmarkPort-Wine Stain1 moreThis is a multi-center, randomized, double-blind, vehicle-controlled, and sequential group Phase 2 study. Eligible subjects aged 18 to 65 years old with PWB of face and/or neck area (except subjects for Stage One) will receive Hemoporfin PDT or vehicle PDT in 8-week cycles at fixed drug dose (5 mg/kg) and different light fluence.
Pilot Study to Evaluate the Effect of Multiple Passes on Port Wine Stain Treatments With the Cutera...
Port-Wine StainTwo 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.
Clinical Characteristics of Infantile Hemangioma
HemangiomaThe 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.
Skin Imaging to Inform Laser Treatments
Port-Wine StainRosacea2 moreThe 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.
