Nd-YAG laser phototherapy has been demonstrated to be effective for the treatment of airways obstruction caused by tracheal tumors. Pulmonary edema has been reported as a complication following acute relief of an upper airway obstruction. We describe a case where laser photoresection of an endotracheal malignancy resulted in acute pulmonary edema. It is important to recognize this potential cau...

Phototherapy involves repeated exposure of the skin to ultraviolet light to treat various inflammatory skin conditions such as psoriasis. Recent studies have identified specific immunologic effects of phototherapy that may underlie phototherapy efficacy. Furthermore, recent advancements have been made in developing safe and effective targeted phototherapy modalities for difficult-to-treat areas...

Applications of laser therapy, including low-level laser therapy (LLLT), phototherapy and photodynamic therapy (PDT), have been proven to be beneficial and relatively less invasive therapeutic modalities for numerous diseases and disease conditions. Using specific types of laser irradiation, specific cellular activities can be induced. Because multiple cellular signaling cascades are simultaneo...

PURPOSE To present the state-of-the-art of subthreshold diode laser micropulse photocoagulation (SDM) as invisible retinal phototherapy for diabetic macular edema (DME). METHOD To review the role and evolution of retinal laser treatment for DME. RESULTS Thermal laser retinal photocoagulation has been the cornerstone of treatment for diabetic macular edema for over four decades. Throughout, ...

affecting 2.6 percent of the US population. It is debilitating both physically and mentally, and there is always a need to develop treatment options with better success rates, not only acutely, but long-term. Despite the wide range of treatment options available, UVB phototherapy remains one of the safest therapeutic modalities for psoriasis. The latest development in UVB phototherapy is the ex...

Multifunctionalization of carbon nanotubules is easily achieved by attaching functional molecules that provide specific advantages for microscopic applications. We fabricated a double photodynamic therapy (PDT) and photohyperthermia (PHT) cancer phototherapy system that uses a single laser. Zinc phthalocyanine (ZnPc) was loaded onto single-wall carbon nanohorns with holes opened (SWNHox), and t...

OBJECTIVE This pilot double-blind randomized study evaluated the efficacy of 780-nm laser phototherapy on the acceleration of axonal growth and regeneration after peripheral nerve reconstruction by polyglycolic acid (PGA) neurotube. BACKGROUND DATA The use of a guiding tube for the reconstruction of segmental loss of injured peripheral nerve has some advantages over the regular nerve grafting...

OBJECTIVE The objective of this study was to compare the outcomes of LED phototherapy and laser acupuncture treatment on allergic rhinitis in children. METHODS 40 patients with perennial allergic rhinitis were divided randomly into two groups. Patient's ages ranged from 7 to 18 years. One group was subjected to LED phototherapy and the other group was managed by laser acupuncture .The patient...

Phototherapy is a promising strategy for cancer treatment due to its selective and localized therapeutic effect by laser irradiation. Photothermal therapy damages malignant cells by using heat converted from light by an agent. On the other hand, photodynamic therapy uses photosensitizers that become cytotoxic upon irradiation with laser light at excitation wavelength. As singular treatment of e...

Bronchoscopic phototherapy is available now for 2 distinct categories of tracheobronchial cancer: roentgenographically occult superficial squamous cell carcinoma and advanced malignancy causing significant airway obstruction. Laboratory and clinical experience show that the photodynamic effect of hematoporphyrin derivative phototherapy (HpD-PT) may be useful for treating superficial cancers tha...
