BACKGROUND: An intense pulsed light (IPL) narrowband "KTP/PDL-like" filter (525–585 nm) may combine the tolerability of the IPL with the precision of KTP and PDL lasers. This study evaluated the impact of IPL with a KTP/PDL-like filter on telangiectasias. METHODS: This was a single-center, prospective study of 17 subjects with facial telangiectasias and skin types I–III. Three monthly treatments were performed using this specific filter, with follow-up visits at 1, 3, and 6 months. Telangiectasia improvement was assessed by the investigator and subjects using a 5-point scale. Facial photographs and safety assessments were obtained at each visit. Subject discomfort was evaluated using a visual analog scale (VAS) immediately posttreatment, and subject downtime was recorded at each subsequent visit. RESULTS: All facial telangiectasias significantly improved. At 1-month follow-up, >50% lesion clearance was noted in 97.1% of facial (n=36) and 85.7% of non-facial (n=7) lesions, with 73% of subjects satisfied or very satisfied. An increase in mean social downtime (0, 2.3, and 3 days) and VAS scores (3.5, 4.5, and 4.8) with treatments 1, 2, and 3, respectively, mirrored a stepwise increase in fluence with subsequent sessions. CONCLUSIONS: The use of a novel IPL narrowband KTP/PDL-like filter can significantly improve facial and non-facial telangiectasias with minimal downtime.

Cutis marmorata telangiectatica congenita (CMTC) is a rare vascular disorder characterized by blue-purple reticulated patches and plaques that can be localized or generalized. Associated skin atrophy and soft tissue hypoplasia is common while ulceration is relatively uncommon. As CMTC is exceedingly rare and spontaneous remission in childhood can occur in mild cases, evidence for treatment of severe, refractory disease is limited. We present the case of a four-year-old female with CMTC and associated painful, recalcitrant ulcers successfully treated with a combination of pulsed dye laser and intense pulsed light therapy.

Port wine stains (PWSs) are congenital vascular malformations that progressively darken and thicken with age. Currently, laser therapy is the most effective way in clinical management of PWS. It is known that skin pigmentation (melanin content) affects the radiant exposure that can be safely applied to treat PWS. However, the effect of melanin distribution in the epidermis on the maximum safe radiant exposure has not been studied previously. In this study, 10 different morphological distributions of melanin were proposed according to the formation and migration characteristics of melanin, and the two-scale heat transfer model was employed to investigate the influence of melanin distribution on the threshold radiant exposure of epidermis and blood vessels. The results show that melanin distributions do have a strong effect on laser parameter selection. When uniform melanin distribution is assumed, the threshold radiant exposure to damage a typical PWS blood vessel (50 µm diameter) is 8.62 J/cm2 lower than that to injure epidermis. The optimal pulse duration is 1-5 ms for a typical PWS blood vessel of 50 µm when melanin distribution is taken into consideration. PWS blood vessels covered by non-uniformly distributed melanin are more likely to have poor response to laser treatment.

A 39-year-old male commercial diver developed cutis marmorata after a dive. He had a full recovery after therapy in a hyperbaric oxygen chamber. Transthoracic echocardiography revealed an atrial septal aneurysm and a large shunt during normal respirations. This form of decompression sickness may progress to type II DCS, thus is important to identify and treat. Cutis marmorata as a result of diving is highly associated with an atrial septal defect or a large patent foramen ovale. It is particularly important to assess these patients for a right-to-left shunt as part of a medical evaluation prior to returning to diving.

Cutis marmorata telangiectatica congenita is a rare disorder characterized by cutis marmorata, telangiectasia with or without recurrent ulcerations. It is a benign vascular anomaly with dilatation of capillaries and veins in the dermis. There is no satisfactory treatment for the ulcerative variety of cutis marmorata telangiectatica congenita. In this case, intense pulse light therapy was used with almost near total cure. Intense pulse light with its vascular filter of wavelength 550-1200 nm was used every fortnight till complete resolution of lesions.

Importance: Livedoid vasculopathy is a painful, ulcerative condition of the lower extremities for which no established treatment exists. Current treatment paradigms rely on low levels of evidence, primarily case reports and case series. Objective: To systematically review the treatment for livedoid vasculopathy and synthesize the available clinical data. Evidence Review: A systematic review of the literature using Ovid MEDLINE (covering the period January 1, 1946, through June 9, 2017) and Ovid EMBASE (covering January 1, 1947, through June 9, 2017) databases was performed with a broad and inclusive search strategy along with a subsequent search of the references of retrieved articles. All case series reports published in the English language and in a peer-reviewed journal discussing the treatment for livedoid vasculopathy diagnosis were included. Findings: A total of 29 case series reports published in the English language and in a peer-reviewed journal discussed the treatment for livedoid vasculopathy. These reports represented a total of 339 patients, of whom 230 (68%) were female and 69 (20%) were male; sex was not stated for 40 patients. Treatment with anticoagulants, antiplatelets, anabolic steroids, thrombolytics, hyperbaric oxygen, intravenous immunoglobulins, vitamin supplementation, UV light, and a combination of 1 or more of these among other therapies had a favorable outcome. Anticoagulants were the most commonly used monotherapy, achieving a favorable response in 62 of 63 patients (98%). Anabolic steroids, intravenous immunoglobulins, and antiplatelets were the second, third, and fourth most commonly used treatments, respectively. All of these therapies were associated with good clinical outcomes. Adverse events were observed in 44 patients (13%). Conclusions and Relevance: A variety of treatments with varying degrees of success have been used to treat livedoid vasculopathy. Randomized clinical trials should be performed in the future to better establish these treatments in clinical practice.

Clinical endpoints are immediate or early tissue reactions that occur during laser treatment. They can guide the laser surgeon in delivering safe and effective laser treatment. Some endpoints act as warning signs of injury to the skin; others can indicate a therapeutic response. The first article in this series reviewed undesirable and warning endpoints, and this article focuses on desirable and therapeutic endpoints and their underlying mechanisms in laser surgery. We will also review treatments without clinical endpoints.

The widely used intense pulse light (IPL) technology was first commercially launched to the medical market in 1994 and similar to lasers, is based on the basic principle of selective photothermolysis. The main conflict during treatments with light-based technologies is between safety and efficacy of the treatment. The aim of this study was to evaluate new IPL technology, which integrates three different pulse configurations, with specific attention on the safety and efficacy of the treatment. 101 volunteers (with Fitzpatrick skin types I-VI) were treated as follows: 9 patients underwent 8 bi-weekly acne clearance treatments, 51 patients underwent 6-12 hair removal treatments, 11 patients were treated for general skin rejuvenation, 15 patients were treated for pigmentation lesions, and 15 patients were treated for vascular lesions. No serious adverse events were recorded. All patients that were treated for hair removal achieved significant hair clearance. The patients with facial rosacea responded the fastest to the treatment. Eight of nine patients that were treated for acne clearance achieved significant reduction in acne appearance. The results represented in this study support the approach that when taking into consideration both efficacy of the treatment and safety of the patients, the system should be "flexible" enough to allow exact treatment settings profile for each patient, according to their skin type and the symptom's biophysical characteristics. <

PURPOSE: The aim of this study is to investigate factors associated with residual symptoms after hyperbaric oxygen therapy (HBOT) in type I decompression sickness (DCS). BASIC PROCEDURES: An HBOT registry, which includes patients with type I DCS, was analyzed retrospectively. We divided enrolled patients into two groups; complete resolution group and residual symptom (RS) group after a single HBOT session. We investigated factors associated with residual symptoms at discharge with univariable and multivariable analyses. Restrictive cubic spline curve and a test for trend analysis were used to show the trend of therapeutic response after HBOT based on time from symptom onset to HBOT. MAIN FINDINGS: In a total of 195 patients, 131 (67.2%) patients were included in the RS group after single HBOT. Prolonged time from symptom onset to recompression was independently associated with residual symptoms (P = .004). When patients who underwent recompression within 24 hours from symptom were included in the reference group, the adjusted odds ratios (AOR) (95% confidence interval) of residual symptoms after HBOT were the following: 24 to 96 hours, 2.24 (0.75-6.65); 96 to 240 hours, 3.31 (1.08-10.13); more than 240 hours, 22.83 (2.45-231.43). In terms of sort of diving, commercial and recreational divers had higher probability of residual symptoms than military divers (AOR, 4.78 and 33.36, respectively). PRINCIPAL CONCLUSIONS: Early HBOT is associated with rapid symptom elimination after treatment in type I DCS. Military divers showed a more immediate response after recompression in comparison with commercial and recreational divers.

A probable case of decompression illness with associated cutis marmorata is presented, which regressed over a few hours with oxygen breathing and after intravenous methylprednisolone and fluid resuscitation without recompression. He was eventually transferred for hyperbaric treatment some 10 hours post dive. Cutaneous decompression illness is not associated with high mortality per se, but prompt and accurate recognition is warranted, as it may represent a prodromal feature of potentially life-threatening complications. However, in this case, as differential diagnosis, an allergic reaction remains possible.

BACKGROUND: The Food and Drug Administration (FDA) has approved intense pulsed light (IPL) devices for the treatment of a variety of benign pigmentary and vascular lesions, but the range of disease amenable to IPL treatment continues to expand, and there are no evidence-based clinical guidelines for its use in FDA-approved and off-label indications. OBJECTIVE: To provide evidence-based recommendations to guide physicians in the application of IPL for the treatment of dermatologic disease. EVIDENCE REVIEW: A literature search of the CENTRAL (1991 to May 6, 2013), EMBASE (1974 to May 6, 2013), and MEDLINE in-process and nonindexed citations and MEDLINE (1964 to present) databases was conducted. Studies that examined the role of IPL in primary dermatologic disease were identified, and multiple independent investigators extracted and synthesized data. Recommendations were based on the highest level of evidence available. FINDINGS: Level 1 evidence was found for the use of IPL for the treatment of melasma, acne vulgaris, and telangiectasia. Level 2 evidence was found for the treatment of lentiginous disease, rosacea, capillary malformations, actinic keratoses, and sebaceous gland hyperplasia. Level 3 or lower evidence was found for the treatment of poikiloderma of Civatte, venous malformations, infantile hemangioma, hypertrophic scars, superficial basal cell carcinoma, and Bowen's disease. CONCLUSIONS: IPL is an effective treatment modality for a growing range of dermatologic disease and in some cases may represent a treatment of choice. It is typically well tolerated. Further high-quality studies are required.

Dermatologists encounter a wide range of cutaneous vascular lesions, including infantile hemangiomas, port-wine stain birthmarks, arteriovenous malformations, venous malformations, Kaposi sarcomas, angiosarcomas, and angiofibromas. Current treatment modalities to reduce these lesions include topical and/or intralesional steroids, laser therapy, surgical resection, and endovascular therapy. However, each method has limitations owing to recurrence, comorbidities, toxicity, or lesion location. Photodynamic therapy, antiangiogenic therapy, and evolving methods of sclerotherapy are promising areas of development that may mitigate limitations of current treatments and offer exciting options for patients and their physicians.

Intense pulsed light technology has revolutionized the noninvasive treatment of a whole variety of cutaneous cosmetic problems. Today's machines are safer, more diverse, less painful, and readily available. Intense pulsed lights can be used to treat vascular and pigmented lesions and are used for facial rejuvenation and the removal of unwanted hair. Newer, less powerful home-device intense pulsed light sources will not replace those used in a physician's office but will augment the use of today's more powerful medical office systems.

BACKGROUND AND OBJECTIVE: Pulsed dye laser (PDL) treatment of cutaneous vascular lesions is associated with variable and unpredictable efficacy. Thus, alternative treatment modalities are needed. Previous in vitro and in vivo studies have demonstrated enhanced selective vascular destruction with benzoporphyrin derivative (BPD) monoacid ring A photodynamic therapy (PDT) followed immediately by PDL irradiation (PDT+PDL). Here, we evaluate PDT alone, PDL alone, and PDT+PDL protocols using an optimized in vivo rodent dorsal window chamber model. STUDY DESIGN/MATERIALS AND METHODS: A dorsal window chamber was surgically installed on male Golden Syrian hamsters. BPD solution was administered intravenously via a jugular venous catheter. Evaluated interventions included: (1) Control (no BPD, no light); (2) Control (BPD, no light); (3) PDT alone (lambda = 576 nm; 25, 50, 75, or 96 J/cm2 radiant exposure; 15 minutes post-BPD injection); (4) PDL alone at 7 J/cm2 (585 nm, 1.5 milliseconds pulse duration, 7 mm spot); and (5) PDT (25 or 75 J/cm2)+PDL (7 J/cm2). Laser speckle imaging was used to monitor blood flow dynamics before, immediately after, and 1, 3, and 5 days post-intervention. RESULTS: Perfusion reduction on day 1 post-intervention was achieved with PDT>50 J/cm2, PDL alone, and PDT+PDL. However, by day 5 post-intervention, recovery of flow was observed with PDT alone at 50 J/cm2 (-15.1%) and PDL alone (+215%). PDT (75 J/cm2)+PDL resulted in the greatest prolonged reduction in vascular perfusion (-99.8%). CONCLUSIONS: Our in vivo data suggest that the PDT+PDL therapeutic protocol can result in enhanced and persistent vascular shutdown compared to PDT or PDL alone. The PDT+PDL approach has potential for considerable superficial vascular destruction and should be considered as a treatment modality for cutaneous vascular lesions. Monitoring of blood flow changes for as long as possible is crucial for accurate assessment of light-based vascular interventions.

Calcific uremic arteriolopathy (CUA) is a rare but serious complication of end-stage renal disease presenting as painful cutaneous lesions and progressing to non-healing ulcers and gangrene. This syndrome is associated with calcium and phosphorus deposits within small arteries of the skin. The pathognomonic lesion is vascular calcification with intimal arterial hypertrophy and superimposed small-vessel thrombosis. The condition is being increasingly recognized and reported as a contributing factor to death in dialysis patients, with secondary infection and sepsis as the major cause of mortality. No standard treatment has been established for this syndrome. We present the therapeutic approach employed in two patients, which successfully resulted in healing of the lesions, using a combination of measures to control the factors potentially related to development of CUA and hyperbaric oxygen therapy.

Treatment and course of leukocytoclastic immune-complex vasculitis (LcV) depend on absence or presence of IgA in immune complexes [Henoch-Schoenlein-Purpura (PSH)]. LcV due to IgG- or IgM-containing immune complexes has a better prognosis. If triggers cannot be detected or avoided, symptomatic treatments are usually sufficient due to a usually favourable course. When hemorrhagic blisters suggest incipient skin necrosis corticosteroids are indicated. For chronic or relapsing LcV we suggest colchicine or dapsone. In adults with PSH and severe glomerulonephritis there is insufficient evidence for the efficacy of glucocorticoids; but e.g. ACE inhibitors can be helpful depending on symptoms. In cryoglobulinemic vasculitis underlying diseases (often plasmocytoma or hepatitis C) should be treated, sometimes supplemented by plasmapheresis. Dapsone or colchicine are usually started for urticarial vasculitis. ANCA-associated systemic vasculitis requires rapid and aggressive induction therapy, usually with glucocorticoids and cyclophosphamide. In classic polyarteriitis nodosa glucocorticoids improve prognosis, in polyarteriitis nodosa cutanea colchicine or dapsone are more appropriate. Giant cell arteriitis requires rapid therapy with glucocorticoids. For livedo vasculopathy antithrombotic measures are required with low molecular heparin or antagonists to vitamin K, for maintenance dipyridamol und aspirin.
