Background: The alexandrite laser selectively targets melanin and hemoglobin. We used the alexandrite laser with variable pulse widths to treat facial telangiectasia.
Methods: Nineteen patients were enrolled in this study, which consisted of two parts: a series of test spots over a range of pulse durations (3-80 ms) and treatment over a larger area based on the pulse width-specific outcomes from the test spots. The final follow-up visit was 12 weeks after irradiation.
Results: The 40-ms pulse width achieved the optimal balance of pain tolerance, epidermal tolerance, and vessel reduction. Mean fluence was 88 J/cm(2), with a 6-mm spot. Overall, a 48% reduction in vessels was noted after one treatment. Side effects were minimal.
Conclusions: In fair-skinned patients with large telangiectasia, the alexandrite laser is a good option for vessel reduction.

Laser-Driven Dissection Achieves Earlier Continence Recovery Than Blunt Dissection During Holmium Laser Enucleation of the Prostate.
Low Urin Tract Symptoms

Farwaniya Hospital, Farwaniya, Kuwait.
Objectives: During holmium laser enucleation of the prostate (HOLEP), blunt dissection (BD) by pushing the tip of the scope may exert mechanical force on the sphincter that could be avoided by adopting laser dissection (LD). This study evaluates the continence recovery in consecutive patients who underwent BD and LD.
Methods: A prospective cohort of patients who underwent LD was compared with a retrospective control that underwent BD.

: This study aimed to evaluate the recurrence rates at three years for upper tract urothelial carcinoma (UTUC) cases managed conservatively, using Narrow Band Imaging (NBI)-assisted flexible ureteroscopy and Holmium laser vaporization. : The study group included 61 patients who were diagnosed with NBI-assisted visualization with superficial pyelo-calyceal urothelial tumor lesions, treated conservatively by the flexible ureteroscopic approach and Holmium laser vaporization, also assisted by NBI. This was compared with a control group with the same number of cases, which underwent the same procedure, but without NBI technology.

Laser-induced photothermal therapy using gold nanoparticles (AuNPs) has emerged as a promising approach to cancer therapy. However, optimizing various laser parameters is critical for enhancing the photothermal conversion efficacy of plasmonic nanomaterials. In this regard, the present study investigates the photothermal effects of dodecanethiol-stabilized hydrophobic ultrasmall spherical AuNPs (TEM size 2.

In laser safety eyewear, due to the lack of complete blocking of ultraviolet and infrared rays, we proposed a structure based on one-dimensional multilayer composed of several layers of silicon dioxide and zirconium dioxide materials alternately behind polycarbonate lens. It is find out that the acceptance angle range to the photonic crystal is 0 to 39°. This incident angle range corresponds to the band gap of the photonic crystal.

Xanthelasma palpebrarum (XP), characterized by soft, yellowish plaque primarily on the eyelids, is often associated with lipid metabolism disorders. XP can cause aesthetic concerns that affect social interactions and requires careful treatment evaluations due to potential complications and associations with systemic conditions. We aimed to assess the efficacy of and recurrence rates with erbium:yttrium aluminum garnet (Er:YAG) laser therapy in the treatment of XP.
