Our previous study proposed using artificial blood cells (hemoglobin vesicles, Hb-Vs) as photosensitizers in dye laser treatment for port-wine stains (PWSs). Dye laser photons are absorbed by red blood cells (RBCs) and hemoglobin (Hb) mixture, which potentially produce more heat and photocoagulation and effectively destroy endothelial cells. Hb-Vs combination therapy will improve clinical outcomes of dye laser treatment for PWSs because very small vessels do not contain sufficient RBCs and they are poor absorbers/heaters of lasers...

Port-wine stain (PWS) birthmark is a congenital microvascular malformation of the skin. A 1064-nm Nd:YAG laser can achieve a deeper treatment, but the weak absorption by blood limits its clinical application. Multiple laser pulses (MLPs) are a potential solution to enhance the curative effect of a Nd:YAG laser. To reduce the pulse number (pn ) required for the thermal destruction of the blood vessel, the effect of glucose in conjunction with MLP was investigated. In vivo experiments were performed on a dorsal skin chamber model...

Introduction: Pulsed dye laser (PDL) for treatment of port wine stain (PWS) usually causes some acute adverse effects, including pain, erythema, scabbing and swelling. This study aimed to determine whether topical halometasone can be used to reduce these acute adverse effects for post-PDL care of patients. Methods: A total of 40 PWS subjects were enrolled in this study and randomly assigned into two regimens: PDL alone and PDL + halometasone. All subjects were given a single treatment of PDL with wavelength of 595 nm, fluence of 8...

Port-wine stains (PWS) are congenital capillary malformations, usually occurring on the face, neck, and other exposed parts of the skin, that have serious psychological and social impact on the patient. Most researchers focus on the treatment of PWS, but the quality of life (QoL) of PWS patients is seldom researched. The objective of this study is to evaluate the QoL of patients with PWS on exposed parts and explore the factors influencing the QoL of PWS patients. The QoL of 197 cases with PWS on exposed parts were prospectively studied using the Dermatology Life Quality Index questionnaire (DLQI), and the factors influencing the patients' QoL were analyzed by single-factor analysis and multiple-factor logistic regression analysis...

BACKGROUND: Pulsed dye laser is the gold standard for port-wine stain (PWS) treatment. However, pulsed dye lasers achieve suboptimal clinical results in a majority of patients. Patient demand for novel therapies and willingness to participate in clinical studies is currently unknown, yet, imperative for steering R&D activity. The objective of this study was to evaluate these two factors in relation to PWS patient demographics. METHODS: A questionnaire was used to assess patient and PWS characteristics, treatment history, efficacy, and satisfaction, stress level, willingness to travel and pay for an effective treatment, participation in clinical studies, and amenability to intravenous drug administration...

Capillary malformations (CMs), also known as port-wine stains, are the most common type of congenital vascular malformations. Facial CM often occurs with a quasidermatomal distribution according to the sensory trigeminal nerve distribution. With time, these lesions darken progressively, and soft tissue hypertrophy, bony hypertrophy, and/or nodule formation can develop. Multiple treatments for CM have been reported. However, the mainstay and gold standard therapy for facial or aesthetically sensitive CM is still the pulsed dye laser treatment...

Neodymium:yttrium aluminum garnet (Nd:YAG) lasers exhibit considerable potential for treating deeply buried port-wine stains. However, the application of Nd:YAG laser is limited by its weak absorption to blood. This in vivo study tested the efficacy and safety of utilizing thiol-terminated methoxypolyethylene glycol-modified gold nanorods (PEG-GNRs) to enhance the absorption of Nd:YAG laser to blood. Mouse mesentery and dorsal skinfold chamber (DSC) model were prepared to analyze the thermal responses of a single venule without anatomic structures, as well as blood vessels in the complex structure of the skin, to laser light...

Proteus syndrome is a rare syndrome characterized by disproportionate overgrowth of limbs, multiple hamartomas, and vascular malformations. The cerebriform connective tissue nevi, also called cerebriform plantar hyperplasia, are present in most patients, and is the main characteristic of the syndrome. If present, even alone, they can be considered as a pathognomonic sign. This article reports a classic case of Proteus syndrome in a 2-year-old male patient who began to show a discrete asymmetry of the right hemibody in relation to the left one after birth, which increased over the months...
