BACKGROUND: Plenty of researches focused on treatment efficiency and/or treatment reactions of photodynamic therapy (PDT) on port-wine stain (PWS). But few studies reported the association between them. Hence, here we investigated the association between the treatment efficiency and treatment reactions after Hemoporfin mediated photodynamic therapy (HMME-PDT) on PWS through a prospective study. METHODS: Patients (n=50) with PWS were randomly assigned to the HMME group or the placebo group...

Based on the principle of selective photothermolysis, 1064 nm Nd:YAG laser has great potential for the treatment of deeper and larger PWS. However, the clinical effectiveness is limited because of the weak absorption of blood to Nd:YAG laser. The aim of this study is to obtain the optimal irradiation conditions to effectively destroy vascular lesions with the assistance of PEG-modified gold NRs to enhance blood absorption of Nd:YAG laser. In our study, PEG-modified gold NRs were prepared by the seeded growth method...

Sturge-Weber syndrome is a sporadic congenital neurocutaneous disorder caused by a somatic activating mutation in GNAQ; it affects 1 in every 20,000 to 50,000 newborns. It is characterized by a facial Port-wine stain, leptomeningeal angiomatosis, and glaucoma. Seizures are the most common neurological manifestation and typically present in the first months of life. Glaucoma may be present at birth or develop later. Neuroimaging studies show leptomeningeal angiomatosis, supporting diagnosis. Standard treatment for Sturge-Weber syndrome includes laser treatment for the Port-wine stain, anticonvulsants, and medical or surgical treatment for the glaucoma...

Pain is a common side-effect of dermatological laser procedures. Non-invasive anaesthetic drugs and anaesthetic procedures can be used to provide pain relief and increase patient satisfaction and treatment efficacy. However, it remains unclear which method provides the best pain relief. The objective of this systematic review was therefore to assess the efficacy and safety of non-invasive anaesthetic methods during dermatological laser procedures. A systematic literature search was conducted. Randomized and non-randomized controlled clinical trials (RCTs and CCTs) were included...

Laser treatment is the most effective therapy in dermatology for vascular skin disorders, such as port-wine stains (PWS). Changes in heat-induced absorbance in blood must be determined for accurate numerical simulation and implementation of multi-pulse laser therapy for treatment of PWS. Thermally induced absorbance changes in hemoglobin in blood were compared in vitro between slow water bath heating and fast heating irradiated by using sub-millisecond Nd:YAG laser. Blood composition at different temperatures was calculated by comparing blood absorption spectra with those of pure HbO2, Hb, and metHb at room temperature...

BACKGROUND: Pulsed dye laser (PDL) is the treatment of choice for port-wine stains (PWS). Some PWS are recalcitrant to this modality. A number of reasons for PDL treatment resistance have been described, including inadequate heat generation. OBJECTIVE: We evaluated PDL combined with radiofrequency (RF) energy into a single device to target larger and deeper blood vessels and overcome PDL resistance. METHOD: This was an open-label, prospective, single-center investigation of a novel device combining RF energy with PDL conducted to treat recalcitrant PWS...

Port wine stain (PWS) is a congenital, progressive vascular malformation. Many patients with PWS develop hypertrophy and discrete nodularity during their adult life, but the mechanism(s) remain incompletely understood. In this study, we attempted to investigate activation status of PKCα, PI3K, PDPK1 and PLC-γ and protein levels of PP2A and DAG to explore their potential roles in the formation of hypertrophic and nodular PWS lesions. We found phosphorylated levels of PKCα, PI3K, PDPK1, and PLC-γ and protein levels of PP2A and DAG showed moderate increases in the endothelial cells of hypertrophic PWS as compared to the adjacent normal skin...

BACKGROUND: Facial port-wine stains (PWS) are considered by some an aesthetic skin problem, yet impact on quality of life (QoL) has not been objectively documented. OBJECTIVE: We sought to (1) characterize the effect of PWS on QoL in adults, (2) to identify the clinical and demographic factors that affect QoL, and (3) to compare our results with QoL studies in other skin conditions. METHODS: In total, 244 adults with facial PWS completed an online QoL survey, which included the Skindex-29 instrument...

BACKGROUND: Several cellular functions relate to ion-channels activity. Physiologically relevant chains of events leading to angiogenesis, cell cycle and different forms of cell death, require transmembrane voltage control. We hypothesized that the unordered angiogenesis occurring in solid cancers and vascular malformations might associate, at least in part, to ion-transport alteration. METHODS: The expression level of several ion-channels was analyzed in human solid tumor biopsies...

BACKGROUND: Lasers have been the treatment of choice for Port-wine stain (PWS). However, only one type of laser is not a panacea for all PWS malformations. This is may be due to the great heterogeneity of phenotypic presentation of this congenital anomaly as color, depth, and the site of the lesion. For the treatment of PWS, flash lamp-pumped pulsed dye laser, carbon dioxide, argon, krypton, copper bromide, frequency-doubled neodymium:yttrium-aluminum-garnet (Nd:YAG), and also intense pulsed light sources can be used...

BACKGROUND: Sturge-Weber syndrome is characterized by a facial port-wine stain associated with either or both a retinal angioma and a cerebral pial angioma. Because a pial angioma may not be evident on the initial imaging studies, individuals at risk for epilepsy are often not identified before their first seizure. The aim of this study is to identify predictive factors predisposing Sturge-Weber patients to epilepsy. METHODS: The medical archives and photography database of our institution were reviewed to identify Sturge-Weber Syndrome patients followed up between 1990 and 2015...

Regarded singly, both Sturge-Weber syndrome and trigonocephaly are rare congenital disorders. The cardinal features of Sturge-Weber syndrome are facial cutaneous capillary malformation (port-wine stain), leptomeningeal angiomatosis, and glaucoma. Premature closure of the metopic suture results in trigonocephaly. However, to the best of our knowledge, the diagnosis of a combination of both Sturge-Weber syndrome and trigonocephaly has not as yet been reported. This brief clinical study thus presents a patient with the unusual findings of a Sturge-Weber syndrome and simultaneous trigonocephaly induced by premature metopic synostosis...

We report a case of a suspected Sturge-Weber syndrome variant diagnosed at the age of 58 with the help of enhanced depth imaging spectral-domain ocular coherence tomography (EDI-SDOCT). A 58-year-old female with unilateral glaucoma was suspected to have choroidal vascular lesion, conjunctival angioma, and no facial port-wine stain who presented to the clinic with bleb dysesthesia many years after trabeculectomy. EDI-SDOCT was performed and revealed markedly increased choroidal thickness in the affected eye...

The aim of this study is to report the results of intensive therapy of lymphedema associated with Klippel-Trenaunay syndrome. A 24-year-old female patient reported that her family had observed edema in her right leg and port wine stains from birth. For ten years, they consulted with different specialists in the region but the prognosis did not change and no specific treatment was found. In 2014, at the age of 24, with massive lymphedema, a leg ulcer, and recurrent infections, she started treatment at the Clínica Godoy in São José do Rio Preto...

Characterizing port wine stains (PWS) with its optical parameters [i.e. absorption coefficient (μ a) and reduced scattering coefficient (μ s')] and microvascular parameters [i.e. blood volume fraction (BVF), mean vessel diameter (MVD), and oxygen saturation (StO2)] is extremely important for elucidating the mechanisms for its light-based treatments, such as pulsed dye laser and photodynamic therapy. In this study, a customized diffuse reflectance spectroscopy (DRS) probe with an appropriate source-detector distance was used to measure the diffuse reflectance spectra of PWS lesions in clinical practice...

Klippel-Trénaunay syndrome (KTS) is a rare congenital malformation characterized by a triad of clinical presentations: (1) capillary malformations manifesting as a "port wine stain"; (2) limb hypertrophy; and (3) venous varicosities. It is distinguished from Parkes-Weber syndrome by the absence of substantial arteriovenous shunting. Due to the clinical implications of an arteriovenous fistula, differentiation between the two syndromes is important, as the prognosis and treatment greatly differ. We present a series of 5 cases of suspected KTS, while emphasizing the difficulties in distinguishing KTS from Parkes-Weber syndrome without diagnostic imaging and underscoring the importance of accurately classifying patients with the appropriate syndrome...

Vascular stains are a common reason for consultation in pediatric dermatology clinics. Although vascular stains include all vascular malformations, the term is most often used to refer to capillary malformations, but capillary malformations include a wide range of vascular stains with different clinical features, prognoses, and associated findings. The discovery of several mutations in various capillary malformations and associated syndromes has reinforced these differences, but clinical recognition of these different types of capillary vascular stains is sometimes difficult, and the multitude of classifications and confusing nomenclature often hamper the correct diagnosis and management...
