Randomized Controlled Trial Clinical Trial
60-minute application of S-Caine Peel prior to 1,064 nm long-pulsed Nd:YAG laser treatment of leg veins.
Advancements in laser treatment of leg veins necessitate concurrent investigations in topical anesthesia to minimize treatment-related pain. To evaluate the efficacy of the S-Caine Peel for providing topical anesthesia after a 60-minute application. ⋯ The S-Caine Peel is safe and effective when applied for 60 minutes prior to laser therapy of leg veins.

Randomized Controlled Trial Clinical Trial
Efficacy of 904 nm gallium arsenide low level laser therapy in the management of chronic myofascial pain in the neck: a double-blind and randomize-controlled trial.
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.

Comparative Study
Increased brain tumor resection using fluorescence image guidance in a preclinical model.
Fluorescence image-guided brain tumor resection is thought to assist neurosurgeons by visualizing those tumor margins that merge imperceptibly into normal brain tissue and, hence, are difficult to identify. We compared resection completeness and residual tumor, determined by histopathology, after white light resection (WLR) using an operating microscope versus additional fluorescence guided resection (FGR). ⋯ Additional FGR increased completeness of resection and enabled more consistent resections between cases.

Comparative Study
Comparison of red and green laser doppler imaging of blood flow.
Laser Doppler imaging (LDI) of perfusion has been performed with a novel green wavelength (532 nm) for comparison with a HeNe laser (633 nm), the aim being validation of the green laser wavelength as a research tool. ⋯ Red and green wavelengths appear to image different components of the microcirculation.

Qualitative laryngoscopic investigations belong to diagnostic routine in laryngology. Nevertheless, quantitative morphometric measurements of intralaryngeal structures have been difficult by now. ⋯ In our opinion this method enables accurate quantitative morphological measurement within the larynx that could be used even in clinical routine. The two-point light projection technique helps to reduce former limitations of endoscopic investigations.
