“Outpatient laser ablation of palatine tonsils is a very interesting procedure that has been recently introduced selleck screening library as a routine in head and neck surgery departments. The aim of this study was to describe a new strategy using a Doppler-guided fibre optic neodymium-yttrium-aluminium-garnet (YAG) laser to remove up to 80 % of tonsillar tissue, as assessed in the long-term postoperative clinical evaluation of the volume of the tonsils at the follow-up, and leaving the capsule in place, thus avoiding any haemorrhagic complication and minimize pain. A total of 20 patients (men, n = 13; women, n = 7), aged between 6 and 63, were recruited for the procedure. They were affected by chronic hypertrophic tonsillitis with a recurrent

fever and other symptoms that were related to oral inflammation. Among the 20 patients, no serious adverse events, including haemorrhage-related complications, were observed. Treatment was well tolerated, even in patients displaying an overall low pain threshold. No dropout or uncompleted procedure occurred in the present study. Minor complications included sore throat, moderate oedema, mild acute pharynx inflammation, slight peritonsillar exudate and local burning. The postoperative pain, measured by Scott-Huskisson visual analogue scale, was between 5 and 40 mm and was easily counteracted by means of external ice packages and nonsteroidal anti-inflammatory drugs, according to the individual patient’s ABT-737 cost need. During the 12-36-month follow-up patients

showed improved symptoms (n = 7) and complete recovery (n = 13). A relapse episode was observed in two patients. This study supports fibre optic laser neodymium-YAG tonsil surgery, named “”cribriform intracapsular tonsillectomy”" or “”Swiss-cheese laser tonsillectomy”", as GSK126 an effective alternative to the traditional cold knife approach or electrosurgery. This approach could become the gold standard for tonsil surgery in the third millennium for safety reasons, acceptable cost-benefit ratio, the precise targeting of the beam across the affected tissues and the short- and long-term recovery.”
“The impact of hot-air drying on essential oil content and composition of lemon balm leaves (Melissa officinalis L) was investigated at different temperatures within the range of 30 and 90 degrees C, constant specific humidity of 10 g kg(-1) dry air and uniform air flow of 0.2 m s(-1). Essential-oil reduction was determined by hydrodistillation of samples during drying and the experimental data was fitted to a first-order reaction kinetics model. The dependence of temperature on the rate constant was expressed by the Arrhenius-type relationship.
