In mid-February 1986, Peter Ascher and Daniel Choy performed the first percutaneous laser disc decompression (PLDD) procedure at the Neurosurgical Department, University of Graz, Graz, Austria. It was planned to deliver 1000 J of energy with an Nd:YAG laser to a herniated L4-L5 disc causing sciatica. At 600 J the procedure was terminated because the pain was gone. ⋯ The McNab results for the three groups indicate that PLDD is safe, effective, and minimally invasive.

Comparative StudyThe use of light photobiomodulation on the treatment of second-degree burns: a histological study of a rodent model.
The aim of this investigation was to compare, by light microscopy, the effects of the use of laser photobiomodulation (LPBM) and polarized light (PL) on second-degree burns on rodents. ⋯ Despite our findings that the use of both types of light energy improved the healing of second-degree burns at the early stages, long-term assessment is needed to verify if this improvement will influence the final results of treatment.

Comparative StudyA comparative study of the effects of laser photobiomodulation on the healing of third-degree burns: a histological study in rats.
The aim of this investigation was to compare by light microscopy the effects of laser photobiomodulation at wavelengths of 660 and 780 nm on third-degree burns in Wistar rats. ⋯ We concluded that laser photobiomodulation using both wavelengths improved healing of third-degree burns on Wistar rats.

Controlled Clinical TrialEffectiveness of low-level laser therapy in temporomandibular joint disorders: a placebo-controlled study.
Low-level laser therapy (LLLT) treatment for pain caused by temporomandibular joint disorders (TMD) was investigated in a controlled study comparing applied energy density, subgroups of TMD, and duration of disorders. ⋯ The results suggest that LLLT (application of 10 J/cm(2) and 15 J/cm(2)) can be considered as a useful method for the treatment of TMD-related pain, especially long lasting pain.
