Human Computer Interaction Meets Psychophysiology: A Critical Perspective

Human computer interaction (HCI) groups are more and more often exploring the utility of new, lower cost electroencephalography (EEG) interfaces for assessing user engagement and experience as well as for directly controlling computers. While the potential benefits of using EEG are considerable, we argue that research is easily driven by what we term naïve neurorealism. That is, data obtained with psychophysiological devices have poor reliability and uncertain validity, making inferences on mental states difficult. This means that unless sufficient care is taken to address the inherent shortcomings, the contributions of psychophysiological human computer interaction are limited to their novelty value rather than bringing scientific advance. Here, we outline the nature and severity of the reliability and validity problems and give practical suggestions for HCI researchers and reviewers on the way forward, and which obstacles to avoid. We hope that this critical perspective helps to promote good practice in the emerging field of psychophysiology in HCI

Treatment of Recurrent Mixed Infected Laryngocele with Extramucosal Thyrotomy Around Theurepatic Dilemma

Laryngopyocele is a fairly rare disease which is a complication of laryngocele. It is a emergency situation so it needs fast differential diagnosis and treatment. Management of laryngopyoceles include observation, endoscopic resection and resection via an external approach. An external approach is indicated for large or external laryngoceles. The incidence of association between laryngocele and laryngeal carcinoma varies from 1% to 10%. Extramucosal thyrotomy to thyroid cartilage lamina provides adequate visibility of the laryngocele sac

Treatment of Inferior Turbinate Hypertrophies: Low Temperature-Controlled Bipolar Radiofrequency Ablation (Coblation) Versus Monopolar Radiofrequency Probe

Objective: Chronic nasal obstruction caused by inferior turbinate hypertrophies is a common clinical condition. The aim of this study was to compare the effectiveness and safety of Low Temperature-Controlled Bipolar Radiofrequency Ablation (Coblation) with Monopolar Radiofrequency Probe for patients with hypertrophic inferior turbinates.Methods: Twenty four patients with chronic nasal obstruction due to hypertrophic inferior turbinates were enrolled. These patients were randomly assigned to receive Coblation of the inferior turbinate (Group 1) (n = 28) or Monopolar Radiofrequency probe (Group 2) (n = 20). Surgical-outcomes were evaluated objectively by (MRI).Results: A significant recovery in inferior turbinates volumes that were evaluated with MRI were detected 12 weeks after treatment (p<0.05) in group 1. No difference was found from three months after surgery (P > 0.5) in group 2. Postoperative complication depending on this application as epistaxis, infection, synechia, dryness, foul odour, pain and bone necrosis did not occurred in this study.Conclusions: Coblation and monopolar Radiofrequency are both effective at relieving nasal obstruction due to the presence of hypertrophic inferior turbinates. Coblation is superior to monopolar radiofrequency with regard to decreasing the inferior turbinates volumes
