Vitiligo is the most common depigmentation disorder, affecting around 1% of population worldwide. There is no cure, and no firm clinical recommendations can be made for the treatment of vitiligo. A European guideline suggests early treatment of small lesions of recent onset and childhood vitiligo with combination of phototherapy and topical agents. Suitable facilities and equipment, such as hand-held portable phototherapy devices, are needed, if this new guideline is to be implemented. Hand-held units are suitable for small lesions, making phototherapy available for patients with limited and/or early vitiligo...

A much forgotten figure in the history of artificial and natural light therapies, the nurse played a central role in the administration of beneficial - and harmful - ultraviolet radiation in the treatment of skin diseases, tuberculosis and rickets, especially on child patients. As the primary operators of light therapy equipment, nurses specialised in this new and modern treatment, and both the therapy's successes and failures could be attributed to their skill, or lack thereof. This paper provides an introduction to the history of light therapy, especially phototherapy (artificial light therapy), during the early twentieth century in Britain, and to the 'invisible' technicians who contributed so much to its nascent reputation...

Transcranial near-infrared (NIR) treatment of neurological diseases has gained recent momentum. However, the low NIR dose available to the brain, which shows severe scattering and absorption of the photons by human tissues, largely limits its effectiveness in clinical use. Hereby, we propose to take advantage of the strong scattering effect of the cranial tissues by applying an evenly distributed multiunit emitter array on the scalp to enhance the cerebral photon density while maintaining each single emitter operating under the safe thermal limit...

INTRODUCTION: Neonatal jaundice is treated with phototherapy and requires continuous cardiorespiratory monitoring, which can induce parental anxiety. Within a very short time, parents receive the announcement of the diagnosis and of the need for a treatment in another unit with a new team of caregivers. OBJECTIVE: To evaluate parents' anxiety and their feelings concerning the location of treatment concerning cardiorespiratory monitoring equipment (wired vs Wi-Fi wireless monitoring equipment) and treatment location (neonatology vs maternity wards) during a phototherapy treatment in the neonatology unit, located in the maternity wards...

BACKGROUND: Fibromyalgia (FM) is a syndrome most prevalent in women, in whom it is characterized mainly by chronic pain. An important issue is that many patients with FM are reported to have temporomandibular dysfunction (TMD), and the coexistence of these pathologies generates a clinical outcome of high complexity. The literature is unclear regarding an effective therapy for reducing pain in patients with both comorbidities. Exercise training and phototherapy (low-level laser therapy with light-emitting diode) are two of the approaches used to treat pain...

Phototherapy is the use of light for reducing the concentration of bilirubin in the body of infants. Although it has become a mainstay since its introduction in 1958, a better understanding of the efficacy and safety of phototherapy applications seems to be necessary for improved clinical practices and outcomes. This study was initiated to evaluate workers' exposure to Optical Radiation from different types of phototherapy devices in clinical use in Italy. During infant phototherapy the staff monitors babies periodically for around 10 min every hour, and fixation of the phototherapy beam light frequently occurs: almost all operators work within 30 cm of the phototherapy source during monitoring procedures, with most of them commonly working at ≤25 cm from the direct or reflected radiation beam...

BACKGROUND: In neonatal jaundice, phototherapy converts bilirubin to more polar photoisomers which can be excreted without conjugation. We measured changes in the concentration of bilirubin Z,E-photoisomer during the first 4 h of intensive phototherapy using single fluorescent lights as a reference, compared to double fluorescent lights, and a single unit of photodiodes. METHODS: Neonates (N = 42; birth weight: 1,200-4,690 g; gestational age: 28-42 wk) were studied during phototherapy...

BACKGROUND AND OBJECTIVE: It is essential for physicians to be fully informed regarding adverse events and malfunctions associated with medical devices that occur in routine practice. There is limited information on this important issue in the medical literature, and it is mostly based on initial studies and case reports. More advanced knowledge regarding device adverse events is necessary to guide physicians towards providing safe treatments. The FDA requires that manufacturers and device users submit medical device reports (MDRs) for suspected injuries from device use or malfunction...

BACKGROUND: This study will evaluate hypoxia, as a novel concept in the pathogenesis of diabetic macular oedema (DMO). As the oxygen demand of the eye is maximum during dark-adaptation, we hypothesize that wearing light-masks during sleep will cause regression and prevent the development and progression of DMO. The study protocol comprises both an efficacy and mechanistic evaluation to test this hypothesis. METHOD/DESIGN: This is a phase III randomised controlled single-masked multicentre clinical trial to test the clinical efficacy of light-masks at preventing dark-adaptation in the treatment of non-central DMO...

The proposed system has been designed to identify dermatopathologies or to apply personalized phototherapy treatments. The system emits electromagnetic waves in different spectral bands in the range of visible and near infrared to irradiate the target (skin or any other object) to be spectrally characterized. Then, an imaging sensor measures the target response to the stimulus at each spectral band and, after processing, the system displays in real time two images. In one of them the value of each pixel corresponds to the more reflected wavenumber whereas in the other image the pixel value represents the energy absorbed at each band...

BACKGROUND: Icter is the most prevalent disease in newborns. Although most of the newborns affiliated with this seem healthy in other aspects, there is always a fear for toxic complication of indirect hyperbilirobinemia in the central nervous system. Nowadays phototherapy is the method of decreasing (or avoidance of increase) of total serum bilirobin (TSB) and it is also used widely in neonatal health care centers according to the availably of equipment, but without any defined standard...

BACKGROUND: 8-Methoxypsoralen-UVA (PUVA) and narrowband ultraviolet B (NB-UVB) are well-established treatments for chronic plaque-type psoriasis vulgaris. However, long-term risks of PUVA therapy include premature skin ageing and squamous cell carcinoma. OBJECTIVES: To develop a device for targeted UV therapy of psoriatic plaques with protection of the healthy adjacent skin to reduce the risk for premature skin ageing and squamous cell carcinoma. METHODS: In total 28 patients with exacerbated psoriasis vulgaris were treated with the digital phototherapy device skintrek(®) [cream PUVA (n = 8), bath PUVA (n = 11) and UVB (n = 9)] or with conventional bath PUVA (n = 9) or NB-UVB (n = 4)...

Ultraviolet B (UVB) phototherapy is a safe and effective treatment for moderate to severe psoriasis. UVB treatment typically requires patients to visit an outpatient clinic two to three times per week during business hours, a schedule which can be impractical for some individuals. Depending on a patient's insurance coverage, outpatient phototherapy can be expensive. In these situations, home UVB phototherapy may be an additional therapeutic option. Previous studies have shown this treatment to be well tolerated, efficacious, and economical...

Statistical analysis of the daily course of exposures to TL-01 tube radiation for 93 psoriatic patients from the Medical University of Łódź during 20-day phototherapy shows that the dose of 1 J/cm(2) represents a unit of single exposure necessary for psoriasis healing. This value is converted to the antipsoriatic effective dose of 317.9 J/m(2) using the TL-01 lamp irradiance spectrum and the antipsoriatic action spectrum. It is proposed that the daily exposure of 317.9 J/m(2) serves as the standard antipsoriatic dose (SAPD) providing a link between the cabinet and the out-door exposures and it could be used for planning heliotherapy in Poland...

BACKGROUND: Age-related macular degeneration (AMD) is the leading cause of blindness among older adults in the developed world. The only treatments currently available, such as ranibizumab injections, are for neovascular AMD, which accounts for only 10 to 15% of people with the condition. Hypoxia has been implicated as one of the primary causes of AMD, and is most acute at night when the retina is most metabolically active. By increasing light levels at night, the metabolic requirements of the retina and hence the hypoxia will be considerably reduced...
