Targeted gene transfer into rat facial muscles by nanosecond pulsed laser-induced stress waves

We investigate the feasibility of using nanosecond pulsed laser-induced stress waves (LISWs) for gene transfer into rat facial muscles. LISWs are generated by irradiating a black natural rubber disk placed on the target tissue with nanosecond pulsed laser light from the second harmonics (532 nm) of a Q-switched Nd:YAG laser, which is widely used in head and neck surgery and proven to be safe. After injection of plasmid deoxyribose nucleic acid (DNA) coding for Lac Z into rat facial muscles, pulsed laser is used to irradiate the laser target on the skin surface without incision or exposure of muscles. Lac Z expression is detected by X-gal staining of excised rat facial skin and muscles. Strong Lac Z expression is observed seven days after gene transfer, and sustained for up to 14 days. Gene transfer is achieved in facial muscles several millimeters deep from the surface. Gene expression is localized to the tissue exposed to LISWs. No tissue damage from LISWs is observed. LISW is a promising nonviral target gene transfer method because of its high spatial controllability, easy applicability, and minimal invasiveness. Gene transfer using LISW to produce therapeutic proteins such as growth factors could be used to treat nerve injury and paralysis.     

Laser photocoagulation for the treatment of acute peptic-ulcer bleeding. A randomized controlled clinical trial

We tested the hypothesis that therapeutic endoscopy using the Nd:YAG (neodymium:yttrium-aluminum-garnet) laser would benefit patients with acute peptic-ulcer bleeding. Over 43 months, 174 patients with active bleeding (n = 32) or stigmata of recent bleeding (n = 142) due to peptic ulcers were randomly assigned during endoscopy to either standard treatment with laser photocoagulation or therapy without photocoagulation. There were no significant differences in a number of outcomes between the group treated with laser photocoagulation and the control group. Continued bleeding or rebleeding was observed in 22 percent of the laser-treated group and in 20 percent of the control group. Urgent surgery was necessary in 16 percent of the laser-treated patients and in 17 percent of the controls. Laser-treated patients spent a mean of 41 hours in the intensive care unit, and controls spent a mean of 32 hours. The mean hospital stay was 12 days in the laser-treated group and 11 days in the control group. One death occurred in each group. When patients with active bleeding were analyzed separately, there was no significant difference in outcome, even though laser photocoagulation stopped active bleeding in 88 percent of cases. Among patients with visible vessels, rebleeding occurred in 5 of 14 (36 percent) who received laser treatment and 2 of 15 (13 percent) who did not. Laser treatment precipitated bleeding in four patients and duodenal perforation in one. We conclude that Nd:YAG-laser photocoagulation does not benefit patients with acute upper gastrointestinal bleeding from peptic ulcers.     

Endoscopic laser surgery for subglottic stenosis in Wegener's granulomatosis

PURPOSE: Wegener's granulomatosis (WG) is a rare multisystem inflammatory disease, which infrequently involves the subglottic area and trachea. Treatment usually involves the use of immunosuppressive agents with corticosteroids. Some patients, however, continue to have symptoms of airway obstruction after clinical remission following the standard therapeutic regimen. OBJECTIVE: To investigate laser treatment for subglottic stenosis in five patients suffering from WG. MATERIALS AND METHODS: We endoscopically treated 5 patients with subglottic stenosis due to WG and airway obstruction by Nd:YAG and CO2 lasers. One of the patients had preoperative tracheostomy and after treatment was decannulated and could not breathe without dyspnea. Another patient required stenting of the subglottic area. RESULTS: All five patients were able to breathe without dyspnea after the treatment. Three patients were treated with an Nd:YAG laser but needed repeated laser treatment every four to six months, whenever they complained of dyspnea. The other two patients were treated with a CO2 laser; one of these patients had preoperative tracheostomy and was treated twice by CO2 laser and decannulated, with no further difficulty in breathing. The follow-up period was 1-5 years. CONCLUSIONS: Nd:YAG and CO2 lasers are recommended in the treatment of subglottic stenosis (SS) due to WG, particularly when the stenosis is in continuity or close proximity to the vocal cords.     

Long-Pulsed Nd:YAG Laser Treatment of Warts: Report on a Series of 369 Cases

Various treatment methods have been adopted in the management of warts; however, there is still no consensus on first-line treatment. This study was designed to evaluate the efficacy of long-pulsed Nd:YAG laser in the treatment of warts. Over the course of 1 yr, 369 patients with recalcitrant or untreated warts were exposed to a long-pulsed Nd:YAG laser. The following parameters were used: spot size, 5 mm; pulse duration, 20 msec; and fluence, 200 J/cm². No concomitant topical treatment was used. In all, 21 patients were lost during follow up; hence, the data for 348 patients were evaluated. The clearance rate was 96% (336 of the 348 treated warts were eradicated). The clearance rate of verruca vulgaris after the first treatment was very high (72.6%), whereas the clearance rate of deep palmopantar warts after the first treatment was low (44.1%). During a median follow-up period of 2.24 months (range, 2-10 months), 11 relapses were seen (recurrence rate, 3.27%). In conclusion, long-pulsed Nd:YAG laser is safe and effective for the removal or reduction of warts and is less dependent on patient compliance than are other treatment options.
