Sperm motility is enhanced by Low Level Laser and Light Emitting Diode photobiomodulation with a dose-dependent response and differential effects in fresh and frozen samples.

The objective of this study was to investigate the effects of laser and Light Emitting Diode (LED) LLLT photobiomodulation on human spermatozoa motility and DNA integrity. Methods: An in-vitro controlled trial was performed within an IVF clinic laboratory using three human semen specimens, one fresh and two frozen. Sperm were exposed to light from a GaAlAs single laser (810 nm 200 mW) and an LED cluster (660 nm and 850 nm total power 2 W) for various irradiation times. Sperm motility for the test and control aliquots was assessed using a SQA-IIB analyser, but fertilizing ability was not. Sperm chromatin integrity was tested using the Sperm Chromatin Structure Assay. Results: The Sperm Motility Index and Total Functional Sperm Count increased up to four fold compared to controls with inhibitory effects observed at higher doses (longer irradiation times). The maximum effect varied with irradiance and irradiation time and whether the sample was fresh or frozen. Discussion: Human sperm motility is modified by exposure to LLLT and this motility modification is dependent upon beam irradiance and irradiation time as well as the condition of the sample. A higher stimulatory dose provides a rapid increase in motility that is short in duration, while a lower stimulatory dose provides a slower increase in motility. An inhibitory does causes reduced motility. Future research could consider animal models, such as the mouse, to test fertilization capacity and the safety of resu...

Authors: Laubach HJ, Robijns J Abstract Radiation dermatitis (RD), an inflammatory skin disease that can be an unwanted side effect of medical radiation therapy (RT), most commonly occurs in patients undergoing cancer of the ENT, anal, and vulvar regions. The side effects on the skin and mucous membranes occur within a few weeks after the initiation of RT; however, late side effects can develop months to years after the RT. Therapeutically, various treatment approaches are considered such as pentoxifylline, hyperbaric oxygen therapy, laser therapy, and PBMT. In order to limit the reduced quality of life of patients...

AbstractThere are many laser technologies that are being tested that claim to support hair regrowth for patients with alopecia areata (AA). In this paper, we will determine whether the body of evidence supports the use of devices using monochromatic light sources to treat AA. Articles were gathered from PubMed, Embase, and the Cochrane database using these keywords: lasers, excimer laser, low-level laser therapy (LLLT), low-level light therapy, alopecia, alopecia areata, and hair loss with a category modifier of English. Ten clinical trials and seven case reports/abstracts were assessed. Eight clinical trials and two case ...

To the Editor: Lichen planopilaris (LPP) is a lymphocytic scarring alopecia of unknown origin in which the hair follicle stem cells are destroyed by an autoimmune mechanism.1,2 This condition tends to be progressive, and the most effective treatments have response rates of only 10%.1 Low-level laser therapy (LLLT) is an emerging light therapy, with a reported effectiveness in several inflammatory diseases, such as lichen planus, although results are sometimes biased.3 Our objective was to evaluate the potential usefulness of LLLT in patients with LPP.

Conclusion: This study justified the use of TENS therapy as well as LLLT in drug-resistant TMD. Both were useful in relieving the pain and muscles tenderness, although, TENS was more effective than LLLT.  Keywords ●Transcutaneous Electrical Nerve Stimulation  ●Low Level Light Therapy  ●Temporomandibular Joint Disorders Syndrome  ●Pain  ●Laser  ●Temporomandibular Joint  ●Physical Therapy

Conclusion With the guidance of color Doppler ultrasound, the efficacy and safety of long pulse 1064 nmNd:YAG laser, intense pulsed light, and lauromacrogol injection in the treatment of infantile hemangioma have better outcomes compared to laser treatment alone without preoperative ultrasound examination.
