An expert team of marine mammal veterinarians, medical researchers, cosmetic surgeons and dolphin trainers recently joined forces to apply the latest advances in human regenerative medicine in an attempt to restore a bottlenose dolphin's damaged dorsal fin. "Liko's story is a story of medicine with a big heart," said Dr. Rae Stone, a Dolphin Quest veterinarian and co-owner. "It shows extraordinary voluntary cooperation across several human medical and veterinary disciplines that has involved numerous experts with cutting-edge technology and specialized experience. Liko is one very lucky young dolphin." The procedure on Liko, a three-year-old male dolphin at Dolphin Quest on Hawaii's Big Island, took place on July 30 and marked the first-ever marine mammal application of extracellular matrix tissue repair. Liko (pronounced Lee-ko) continues to undergo pioneering veterinary LED (light emitting diode) therapy to stimulate tissue growth and regeneration in his injured fin. |

Fibrotic masses in the breast secondary to fat necrosis or hematoma are a complication of breast reduction mammaplasty. The treatment commonly recommended for this condition is early surgical debridement of necrotic tissue from the entire area, which causes scarring. This case report describes the use of low-intensity laser therapy for fibrotic lumps following reduction mammaplasty. The patient was a 46-year-old woman who had breast reduction surgery 80 days prior to referral for physical therapy. At the time of referral, the largest mass was 8.0 cm in diameter. The patient reported pain and said she was distressed about the breast disfigurement.

A prospective, double-blind, randomized, and controlled trial was conducted in patients with chronic myofascial pain syndrome (MPS) in the neck to evaluate the effects of infrared low level 904 nm Gallium-Arsenide (Ga-As) laser therapy (LLLT) on clinical and quality of life (QoL). This study revealed that short-period application of LLLT is effective in pain relief and in the improvement of functional ability and QoL in patients with MPS. Lasers Surg. Med. 35:229-235, 2004.
On Jan. 28, while loosening up for the Wednesday Night League at Brownsburg Bowl, Leap crushed the end of the little finger on his right hand, which he uses to bowl. A bone graft was used, six weeks later the pins were removed and the finger still was not healing properly. Two weeks later, he heard about cold laser therapy.
"Mostly chiropractors use it," Leap said. "I found one in Brownsburg who does it. I went to him eight times in two weeks. I then went to the hand center and had it X-rayed again. They said the finger was completely healed. I'm a firm believer in cold laser therapy."

Near infrared (NIR) diode laser low-intensity (soft) phototherapy with the topical application of indocyanine green (ICG) has been suggested for treatment of acne vulgaris. Twelve volunteers with acne lesions on their faces and/or backs were enrolled in the experiment. Skin areas of the subjects that were 4x5 cm² were stained with ICG solution for 5 min before laser irradiation (803 nm) at a power density up to 50 mW/cm² for 5 to 10 min. For 75% of the subjects, a single treatment was provided and for the other 25%, eight sequential treatments over a period of a month were carried out.

OBJECTIVE: Low-level laser therapy (LLLT) has been used for the last few years to treat sports injuries. The purpose of this study was to compare three therapeutic protocols in treating edema in second degree ankle sprains that did not require immobilization with a splint, under placebo-controlled conditions. Forty-seven soccer players with second degree ankle sprains, selected at random, were divided into the following groups: The first group (n = 16) was treated with the conventional initial treatment (RICE, rest, ice, compression, elevation), the second group (n = 16) was treated with the RICE method plus placebo laser, and the third group (n = 15) was treated with the RICE method plus an 820-nm GaA1As diode laser with a radiant power output of 40 mW at 16 Hz...
After Embolic Strokes in Rabbits

Because photon energy delivered using a low-energy infrared laser may be useful to treat stroke, we determined whether transcranial laser therapy would improve behavioral deficits in a rabbit small clot embolic stroke model (RSCEM). In this study, the behavioral and physiological effects of laser treatment were measured. The RSCEM was used to assess whether low-energy laser treatment (7.5 or 25 mW/cm2) altered clinical rating scores (behavior) when given to rabbits beginning 1 to 24 hours postembolization. Behavioral analysis was conducted from 24 hours to 21 days after embolization, allowing for the determination of the effective stroke dose (P50) or clot amount (mg) that produces neurological deficits in 50% of the rabbits. Using the RSCEM, a treatment is considered beneficial if it significantly increases the P50 compared with the control group.

The aim of this study was to assess histologically the effect of LLLT (l 830 nm) on the repair of standardized bone defects on the femur of Wistar albinus rats which were grafted with inorganic bovine bone Gen-ox(R). Three randomized groups were studied: group I (control, n=6); group II (Gen-ox(R), n=9) and group III (Gen-ox(R) + LLLT, n=9). The animals were irradiated every 48 h during 15 days; the first irradiation was performed immediately after the procedure. The animals were irradiated transcutaneuosly at four points around the defect. At each point a dose of 4 J/cm(2) was given (Ø~0.6 mm, 40 mW) and the total dose per session was 16 J/cm(2). The animals were killed by an overdose of general anesthetic 15, 21 and 30 days after surgery.
Doctors Use Low-Beam Laser To Treat Injuries, Arthritis, Carpal Tunnel Syndrome
A gentle beam of light can be a powerful weapon against stubborn aches, according to some people who are trying a new low-level laser therapy. Chiropractor Dr. Gary Hartell explained that the treatment uses a gentle beam of light used to ease inflammation and promote healing. He said it is being used to treat all sorts of conditions, including sports injuries, arthritis, carpal tunnel syndrome and even hard-to-heal wounds. "Generally the more acute, more recent injury is going to respond quicker [than] say in several sessions, versus somebody who has had a long-standing chronic problem," Hartell said. Hartell explained how the treatment works: he first uses pinpoint wand to work on acupuncture points.

Years of stretching pizza dough have caused Paul Adamchick of Trucksville to suffer from a very common work-related injury. Adamchick, 35, whose family owns Pizza Perfect in Trucksville, once suffered from carpal tunnel syndrome, a debilitating wrist condition resulting from nerve entrapment. "I had severe hand cramping. I wouldn't be able to sleep at night. My hand was always numb," Adamchick said.
Thanks to a new treatment called "low-level laser therapy," Adamchick says he has been cured. "I can do anything now. I can do what everybody else can do," Adamchick said. "It works. I'm living proof. It's like I have a new pair of hands." Adamchick underwent the therapy six times at the Newhart Chiropractic Center in Plains. Dr. William Newhart believes laser therapy is the "future of medicine."

The aim of this study was to evaluate the effectiveness of the clinical use of the gallium-aluminum-arsenium (GaAlAs) laser at the maximum and minimum energies recommended by the manufacturer for the treatment of dentine hypersensitivity. Dentine hypersensitivity (DH) is a response to a stimulus that would not usually cause pain in a healthy tooth. It is characterized by sharp pain of short duration from the denuded dentin. Its etiology is unknown. The dentin only begins to show sensitivity when exposed to the buccal environment. This exposure can result after removal of the enamel and/or dental cement, or after root denudation. Different treatments are proposed for this disorder.

Over the past decade, lasers and light-based systems have become a common modality to treat a wide variety of skin-related conditions, including acne vulgaris. In spite of the various oral and topical treatments available for the treatment of acne, many patients fail to respond adequately or may develop side effects. Therefore, there is a growing demand by patients for a fast, safe, and side-effect-free novel therapy.

Low power laser therapy (LPLT) effectively reduces pain and improves function and quality of life in patients with knee osteoarthritis (OA), according to a prospective, double-blind study. Effectiveness appears to be independent of dose and duration of laser treatment. LPLT has become a popular, noninvasive alternative treatment; though its effectiveness in osteoarthritis is still controversial. Conflicting results are likely due to variability in the method of application.

A device using specialized light emitting diodes, based on NASA technology for plant growth in space, is continuing to show promise as a treatment to aid healing of bone marrow transplant patients. Use of the LED apparatus has advanced to the second phase of clinical trials in U.S. and foreign hospitals. Results from the first round of tests were highly encouraging, prompting researchers to expand the trials as they seek approval for the treatment as a standard of care for oral mucositis.

Hopes of a breakthrough in treating patients with paralysing back injuries have been raised by a groundbreaking experiment which for the first time fused together a mammal’s broken spinal cord.
The technique in which Scottish-designed lasers were used to repair the spinal cords of paralysed rats – restoring the animals’ mobility – is likely to be tested on humans next year. Professor Juanita Anders, the lead researcher on the project at the Uniformed Services University in Maryland, said that some of the advances in the field of light therapy are “almost too incredible to believe.”

NEW YORK (Reuters Health) - The zap of a low-level laser seems to relieve some cases of chronic swelling in the arm that often occurs after a mastectomy, new research suggests. In a study, swelling diminished significantly in nearly a third of women who received laser treatment for the condition, known as lymphedema. "It's not a quick fix, but it does seem to help in some people and is not invasive," Dr. Colin J. Carati, the study's lead author, told Reuters Health. "Lymphedema is a chronic and progressive condition for which there are few effective treatment options," explained Carati, who is at Flinders University in Adelaide, Australia. Low-level laser treatment has proved effective in improving wound healing and scarring, "so we decided to give it a try in lymphedema," he explained.

Near infra-red light therapy - commonly known as Low Level Laser Therapy- is drawing a lot of attention from research clinicians around the world. For a number of years various researchcenters in Japan, Britain, and the United States have been conducting clinical trials to measure the efficacy of the application of red and near infra-red light over injuries and lesions healing and give relief for both acute and chronic pain. Many of these trials have proven very successful and clearly verified that light can have a positive effect on damaged cells. So much so that the US Defense Advance Research Projects Agency is funding research into the method and hopes to use it to treat some of their personnel whose eyes have been damaged by lasers during combat.
