Photodynamic therapy (PDT) is a technique that utilizes reactive oxygen species produced by a non-toxic dye or photosensitizer molecule in the presence of low intensity visible light to kill mammalian or microbial cells ((1)) . The advantages of PDT are numerous, it is a safe, non-invasive technique which yields effective therapeutic results ((2)) . Photodynamic therapy is not free of adverse effects. The most common one is pain during illumination. With the use of portable light sources to optimize the procedure and facilitate outpatient treatment, the concept of ambulatory PDT has emerged...

Importance: Surgical excision is the standard treatment for cutaneous squamous cell carcinoma (SCC). However, microinvasive SCC (Clark level II) is limited to the papillary dermis, and it should be differentiated from invasive SCC. Ablative fractional laser-primed photodynamic therapy (AFL-PDT) may have enhanced efficacy. Objective: To compare 1 session of AFL-PDT with 2 sessions of conventional methyl aminolevulinate-PDT (MAL-PDT) for the treatment of microinvasive SCC...

Multiple myeloma is characterised by the neoplastic proliferation of a single clone of plasma cells producing a monoclonal immunoglobulin. This clone of plasma cells proliferates in the bone marrow, resulting in extensive skeletal destruction with osteolytic lesions, osteopenia and pathological fractures. Additional disease-related complications include hypercalcaemia, renal insufficiency, anaemia and infection. We present the case of a 64-year-old woman presenting with rapid onset, painful distal symmetrical lower limb weakness and an acute kidney injury...

BACKGROUND: Hyperalgesia or increased sensitivity to pain is often found in alcoholics during alcohol withdrawal and may contribute to relapse drinking. Alternative therapies such as acupuncture and electroacupuncture (EA), through mechanisms involving opioid receptors, may reduce pain and substance dependence and withdrawal syndromes. The lateral habenula (LHb), an epithalamic structure rich in mu opioid receptors (MORs), is a critical target for both drugs of abuse and pain. We previously observed hyperalgesia in rats withdrawn from chronic ethanol (EtOH) drinking and found that EA at the acupoint Zusanli (ST36) reduced EtOH intake...

Kennedy and Pottier discovered that photodynamic therapy (PDT) could be carried out using a procedure consisting of topical application of the porphyrin-precursor, 5-aminolevulinic acid (ALA) to the skin, followed after some time by illumination with various light parameters in the 1980s. Since then, ALA-PDT has expanded enormously and now covers most aspects of dermatological disease. The purpose of this review is to discuss a range of ingenious strategies that investigators have devised for improving the overall outcome (higher efficiency and lower side effects) of ALA-PDT...

Pain during photodynamic therapy (PDT) is the main limiting adverse effect in its use in dermatology. Given its multifactorial nature, we reviewed both intrinsic and extrinsic factors that are involved in PDT pain. We proposed a threshold theory for pain experience in PDT: it positively correlates with fluence rate and dose below certain threshold (rate of ~60 mW/cm(2) , dose of ~50 J/cm(2) ); when threshold is surpassed, pain intensity no longer increases. Additionally, we carefully compared recent updates on pain management strategies and we suggested that cold air analgesia and low-irradiance light source (such as intense pulsed light and day-light PDTs) represent the current best analgesic options...

INTRODUCTION: The non-invasive vulvar Paget's disease is an intra-epidermal carcinoma with glandular characteristics. It appears like an erythematous plaque. The main symptoms are pruritus and pain. The standard treatment is surgical excision in depth. This treatment is complicated with a severe morbidity and photodynamic therapy can be an alternative choice. However, the pain experienced during the photodynamic treatment of vulvar lesion is intense and leads to a premature interruption of the treatment...

Treatments for chronic pain are inadequate, and new options are needed. Nonpharmaceutical approaches are especially attractive with many potential advantages including safety. Light therapy has been suggested to be beneficial in certain medical conditions such as depression, but this approach remains to be explored for modulation of pain. We investigated the effects of light-emitting diodes (LEDs), in the visible spectrum, on acute sensory thresholds in naive rats as well as in experimental neuropathic pain...

High energy laser therapy (HELT) could be a new alternative treatment for lower back pain (LBP), which is a significant public health problem. Nevertheless, differences between the various light waves of HELT have not yet been fully researched. Sixty-six patients with lower back pain were treated using a high energy laser therapy. They were randomized into three different protocols which differed according to wave length (650 nm, 810 nm and TRIAX, which is simultaneous emission of 810 nm, 980 nm e 1064 nm)...

BACKGROUND AND OBJECTIVE: Various irradiances have been reported to be beneficial for the treatment of neuropathic pain with near infrared light. However, the mechanistic basis for the beneficial outcomes may vary based on the level of irradiance or fluence rate used. Using in vivo and in vitro experimental models, this study determined the mechanistic basis of photobiomodulation therapy (PBMT) for the treatment of neuropathic pain using a high irradiance. STUDY DESIGN/MATERIALS AND METHODS: In vitro experiments: Cultured, rat DRG were randomly assigned to control or laser treatment (LT) groups with different irradiation times (2, 5, 30, 60, or 120 seconds)...

OBJECTIVES: Chronic pain and long-term opioid use may lead to a persistent deficit in hedonic capacity, characterized by increased sensitivity to aversive states and insensitivity to natural rewards. Dispositional mindfulness has been linked with improved emotion regulation and pain coping. The aim of the current study was to examine associations between dispositional mindfulness, hedonic capacity, and pain-related interference in an opioid-using chronic pain sample. METHODS: Data were obtained from a sample of 115 chronic pain patients on long-term opioid therapy (68% females, M age=48...

Erythropoietic protoporphyria (EPP) and the phenotypically similar disease X-linked protoporphyria (XLPP) are inherited cutaneous porphyrias characterized clinically by acute non-blistering photosensitivity, intolerance to sunlight, and significantly reduced quality of life. They are due to marked overproduction of protoporphyrin (PP) chiefly by erythroblasts and reticulocytes. In EPP, the underlying genetic defect is in the ferrochelatase gene, which encodes the final enzyme in the heme synthetic pathway. In XLPP, the genetic defect is a gain-of-function mutation, usually a four-base deletion, in the gene that encodes the enzyme 5-aminolevulinic acid synthase-2, the first and rate-controlling enzyme of heme synthesis in developing red blood cells...

Spinal conditions related to intervertebral disc (IVD) degeneration cost billions of dollars in the US annually. Despite the prevalence and soaring cost, there is no specific treatment that restores the physiological function of the diseased IVD. Thus, it is vital to develop new treatment strategies to repair the degenerating IVD. Persons with IVD degeneration without back pain or radicular leg pain often do not require any intervention. Only patients with severe back pain related to the IVD degeneration or biomechanical instability are likely candidates for cell therapy...
