The perioperative course of 41 patients undergoing 85 endoscopic laser resections of central airway lesions under general anaesthesia was reviewed. The CO2 laser was used in 60 procedures and the Nd:YAG in 25. Intravenous anaesthesia and Venturi ventilation were utilized for 65 resections; 20 procedures involved predominantly inhalation anaesthesia via the ventilating bronchoscope. Significant ...

Abstract Plasmonic nanostructures offer wide range of diagnostic and therapeutic functionalities for biomedical applications. Gold nanoparticles (Au NPs) present one the most explored nanomaterial in this field, while titanium nitride (TiN is a new promising with superior plasmonic properties biomedicine. However conventional chemical techniques synthesis these nanomaterials cannot always match...

introduction: vitiligo is a cutaneous disorder of pigmentation, for which, there are some proven modalities of treatment. in this study, we evaluated the efficacy of the addition of topical pimecrolimus to 308nm excimer laser in reducing treatment duration and improving the response rate of eyelid vitiligo, compared with 308nm excimer laser monotherapy. methods: fifty two symmetrically localize...

introduction: temporomandibular disorders (tmd) lead to masticatory muscle pain, jaw movement disability and limitation in mouth opening. pain is the chief complaint in 90% of the tmd patients which leads to disability and severe socioeconomic costs. the purpose of this study was to evaluate the therapeutic effects of low level laser therapy (lllt) compared to pharmacotherapy with nsaids (napro...

objectives: the purpose of this experimental study was to evaluate the efficacy of low level laser therapy (lllt) for pain reduction after midpalatal expansion in rats.   materials and methods: sixty male sprague six-week old rats weighing 180±10g were divided into seven groups (two experimental groups of 24 rats and one control group of 12 rats). the experimental groups were subjected to expan...

background: numerous in vitro reports suggest that low level laser therapy (lllt) affects cellular processes by biostimulation, however most of them emphasize on using visible light lasers which have low penetration. the aim of this study was to determine the effect of infrared laser light (which is more useful in clinic because of its higher penetration) on secretion of fibroblast growth facto...

SUMMARY 13 Consecutive patients who underwent endoscopic Nd - Y AG laser therapy for palliation of advanced esophageal cardnoma were treated between Oct 1989, and July 1991 , in Khatam - al -Anbia Hospital. All patients had severe dysphagia and conventional methods such as surgery , Radiotherapy and chemotherapy failed to treat them. Undoubtedly without laser therapy these patients did not see...

introduction : laser therapy prevents complications of proliferative diabetic retinopathy (pdr), central retinal vein occlusion (crvo) and branch retinal vein occlusion (brvr), but its effect on visual acuity is controversial. this study evaluated the effect of laser on visual acuity in these patients. materials and methods: this interventional study conducted before–after treatment and evaluat...
