The green light potassium-titanyl-phosphate laser photoselective vaporization of the prostate is the latest modality for treatment of benign prostatic obstruction. Because of effective superficial tissue coagulation, intravascular absorption of fluid is minimal; therefore, development of transurethral resection syndrome is unlikely. To our knowledge, this is the first report of a patient underg...

The performance of a new pulsed arc cluster ion source (PACIS) is demonstrated for pure metal cluster ions and anions as well as mixed metal-rare-gas clusters. Pure metal clusters like W$ exhibit intensity distributions similar to those from laser vaporization sources. The ion current of the PACIS is comparable to that of a laser vaporization source. For metal-doped argon cluster ions, a single...

BACKGROUND Genital warts caused by human papillomavirus (HPV) infection are the most common sexually transmitted disease leading to anogential lesions. Although the laser therapy has been shown to be effective in a number of conditions, the use of laser diode vaporization in urological applications and the understanding on its effectiveness as a treatment for various urological conditions is li...

Digital mucous cysts are common tumours of the distal interphalangeal joint, causing pain, cosmetic disfigurement and nail deformities. This study describes six patients suffering from digital mucous cysts, some of which recurred after surgery. Carbon dioxide laser vaporization was performed under local anaesthesia, resulting in complete remission in four out of six patients. In two patients, t...

Liquid fuels are still the primary power source due to its higher energy density and ease of operation compared to gas fuels. Thus a detailed understanding of the spray vaporization and combustion characteristics for various liquid fuels are very important, down to a single droplet. Owing to difficulties in performing droplet level investigation in an actual spray, the spray models are mostly d...

The infantile subglottic hemangioma can be treated in various ways. The results of the treatment used in the Sophia Children's Hospital, intralesional steroids and intubation (IS + I), are discussed and compared with the results of other current treatment methods: CO2 laser vaporization, submucous resection and intubation alone. A total of 18 infants were treated for subglottic hemangioma in ou...

OBJECTIVES To evaluate holmium:YAG laser vaporization of papillary tumours of the bladder, focusing on surgical technique, patients' satisfaction, complications and cost-effectiveness when using the technique under local anaesthesia as an outpatient procedure. PATIENTS AND METHODS In all, 52 consecutive patients with recurrent papillary tumours of the bladder were scheduled for holmium:YAG la...

LASER in the otology field was used to perform tympanotomy and for the placement of ventilation tubes, vaporization of horny pearls and adhesion in the eardrum, remobilisations and ossicular modelings, “spot-welding”; in this field the most argued area of applicability of LASER is the surgery of the otosclerosis. The otosclerosis treatment with surgical LASER started with Perkins and Di Bartolo...
