Tissue adhesive is an excellent alternative for skin incision closure, having the added advantage of ability to shower on the same day, avoidance of the anxiety associated with staple removal, and no General Practitioner (GP) visit required for wound care. The use of tissue adhesive achieves higher patient satisfaction levels and enhances the perception of minimally invasive thyroid surgery (MITS) techniques among patients and surgeons alike.

Activation of inflammatory pathways via reactive oxygen species (ROS) by free fatty acids (FFA) in obesity gives rise to insulin resistance and endothelial dysfunction. Withaferin A (WA), possesses both antioxidant and anti-inflammatory properties and therefore would be a good strategy to suppress palmitic acid (PA)-induced oxidative stress and inflammation and hence, insulin resistance and dysfunction in the endothelium. Effect of WA on PA-induced insulin resistance in human umbilical vein endothelial cells (HUVECs) was determined by evaluating insulin signaling mechanisms whilst effect of this drug on PA-induced endothelial dysfunction was determined in acetylcholine-mediated relaxation in isolated rat aortic preparations. WA significantly inhibited ROS production and inflammation induced by PA. Furthermore, WA significantly decreased TNF-α and IL-6 production in endothelial cells by specifically suppressing IKKβ/NF-κβ phosphorylation. WA inhibited inflammation-stimulated IRS-1 serine phosphorylation and improved the impaired insulin PI3-K signaling, and restored the decreased nitric oxide (NO) production triggered by PA. WA also decreased endothelin-1 and plasminogen activator inhibitor type-1 levels, and restored the impaired endothelium-mediated vasodilation in isolated aortic preparations. These findings suggest that WA inhibited both ROS production and inflammation to restore impaired insulin resistance in cultured endothelial cells and improve endothelial dysfunction in rat aortic rings.

An air-cathode MFC-adsorption hybrid system, made from earthen pot was designed and tested for simultaneous wastewater treatment and energy recovery. Such design had demonstrated superior characteristics of low internal resistance (29.3Ω) and favor to low-cost, efficient wastewater treatment and power generation (55mW/m(3)) with average current of 2.13±0.4mA. The performance between MFC-adsorption hybrid system was compared to the standalone adsorption system and results had demonstrated great pollutants removals of the integrated system especially for chemical oxygen demand (COD), biochemical oxygen demand (BOD3), total organic carbon (TOC), total volatile solids (TVS), ammoniacal nitrogen (NH3-N) and total nitrogen (TN) because such system combines the advantages of each individual unit. Besides the typical biological and electrochemical processes that happened in an MFC system, an additional physicochemical process from the activated carbon took place simultaneously in the MFC-adsorption hybrid system which would further improved on the wastewater quality.

The objective of this survey is to provide an insight into the knowledge and attitude of the higher surgical trainees in Otolaryngology towards evidence based medicine and evaluate their understanding of medical statistics and use of evidence based medicine in patient management. A self administered anonymous questionnaire was distributed to twenty Specialist Registrars in Otolaryngology in Ireland during an annual National Otolaryngology Meeting. Of these, nineteen attempted the questionnaire and eighteen completed it. Three previously published questionnaires [Meserve et al. (2005) Med. Educ. Online.10, 1; McColl et al. (1998) BMJ.316, 361; Khan et al. (1999) J. Obst. Gynaecol.19, 231] were used in this survey. In general, there was a moderately welcoming attitude towards evidence based medicine. However, the survey findings indicate the need for incorporation of formal teaching of critical appraisal skills into medical education with a greater emphasis on involvement and dissemination of evidence based medicine in day to day practice.

The objectives of the study were: first, to determine the prevalence of traditional medicine (TM) and complementary and alternative medicine (CAM) use in head and neck cancer patients in Ireland; second, to educate ourselves on the plethora of CAM/TM options available to patients outside the dominion of conventional medicine. The study design consisted of a cross-sectional survey carried out in three head and neck cancer centres. Self-administered questionnaires were distributed to 110 head and neck cancer patients attending the three cancer centres and data were collected for statistical analysis. A total of 106 patients completed the questionnaire; 21.7% of the participants used CAM/TM since their diagnosis with head and neck cancer. CAM/TM usage was higher in female (34.3%) than in male patients (16.2%). CAM/TM use was more common in the 41-50-year age group, in patients with higher educational levels and those holding strong religious beliefs, and also in married than single patients. The most common types of CAM/TM used were spiritual and laying on of hands. The most common reasons reported for using CAM/TM were to counteract the ill effects of treatment and increase the body's ability to fight cancer. Sources of information on CAM/TM were friends (65%), family (48%) and media (21%). This survey reveals a high prevalence of CAM/TM use in head and neck cancer patients, hence emphasising the need for otolaryngologists to educate themselves on the various therapies available to be able to provide informative advice. There is an urgent need for evidence-based investigation of various CAM/TM therapies currently offered to patients.
