OBJECTIVE This study aims to compare the differences of clinical efficacy and safety of treatment of stable psoriasis vulgaris with calcipotriene ointment in combination with 308 nm excimer laser to 308 nm excimer laser alone. METHODS Randomized, open and self-control trial was conducted in 36 selected patients. The skin lesions from these patients with stable psoriasis vulgaris were divided ...

The photoablative products from human cadaver corneas treated with lasers were investigated using gas chromatography and mass spectroscopy. The photoablations were done separately with an excimer laser (193 nm) and with an erbium: yttrium aluminum garnet (Er:YAG) laser (2.94 microns). More than 20 different types of molecules with a molecular weight of 40-400 mass units could be identified, mos...

The excimer laser machining has been widely applied to micromachining of various materials. An excimer laser dragging process to ablate a groove pattern on a polycarbonate (PC) sheet through a mask opening is analyzed in this paper. Currently, a large number of papers studying the interaction between the laser machining parameters and various materials are presented. However, the prediction of ...

A clinical study was conducted to evaluate the efficacy and safety of percutaneous coronary excimer laser angioplasty in 60 patients with coronary artery disease. Forty-nine patients had stable exertional angina, and 11 patients had unstable angina despite medical therapy. A novel 1.4-mm diameter catheter with 20 quartz fibers of 100-microns diameter each arranged concentrically around a centra...

BACKGROUND The treatment of inverse psoriasis can be both challenging and frustrating. Conventional topical and systemic treatments can be limited in terms of efficacy, acceptability and safety. The 308 nm excimer laser has been shown to be effective in the treatment of psoriatic plaques. METHODS A patient with chronic inverse psoriasis was treated with 308 nm excimer laser using a 3.5 cm spo...

BACKGROUND The survival and growth of melanocytes are controlled by the binding of stem cell factor to its cell surface receptor c-kit+ (CD117). We have observed that c-kit+ melanocytes existed in some lesions of vitiligo, while Melan A+ cells were absent. OBJECTIVE To verify possible relation between c-kit+ expression and treatment response in non-segmental vitiligo lesions. METHODS Skin b...

The improvements in excimer laser technology made hyperopic excimer refractive surgery a valuable option for hyperopia correction. However, despite the good visual and refractive outcomes of excimer laser photorefractive keratectomy (PRK) and laser in situ Keratomileusis (LASIK) treatments, they are more effective and stable for the correction of low degrees of hyperopia than high hyperopia1-7....

esults of excimer laser photorefractive kera-tectomy (PRK) for low and moderate myopia are clinically acceptable. 1,2 After PRK, slight changes in corneal transparency in the ablation zone or some superficial corneal problems can be observed postoperatively, no matter the excimer laser employed. Some reports describe anterior wound healing after excimer laser keratectomy. Tuft et al 3 and Marsh...

BACKGROUND Exfoliative cheilitis is a condition of unknown etiology characterized by hyperkeratosis and scaling of vermilion epithelium with cyclic desquamation. It remains largely refractory to treatment, including corticosteroid therapy, antibiotics, antifungals, and immunosuppressants. OBJECTIVE We sought to evaluate the safety and efficacy of excimer laser therapy and narrowband ultraviol...
