Objective: One of the frequently encountered disorders of wound healing following laryngectomy is pharyngocutaneous fistula. However, although studies have been performed with the aim of prevention of pharyngocutaneous fistulae, there are very few studies with tissue adhesives and platelet-rich plasma. In this study, our aim was to investigate the histopathologic changes in wound healing caused by various tissue adhesives and platelet-rich plasma, together with their effects on prevention of pharyngocutaneous fistula., Methods: 40 male rats were randomly divided into five groups: control, platelet-rich plasma, fibrin tissue adhesive, protein-based albumin glutaraldehyde and synthetic tissue adhesive groups. The pharyngotomy procedure was performed and was sutured. Except the control group, tissue adhesives and platelet-rich plasma were applied. Then, the skin was sutured. On the seventh day, the rats were sacrificed. The skin was opened and pharyngotomy site was assessed in terms of fistulae. The pharyngeal suture line was evaluated histopathologically by using Ehrlich Hunt scale., Results: Inflammatory infiltration was found to be higher in "platelet-rich plasma" group than "fibrin tissue adhesive" and "synthetic tissue adhesive" groups. The fibroblastic activity of "platelet-rich plasma", "fibrin tissue adhesive" and "protein-based albumin glutaraldehyde" groups was higher than the control group. The positive changes created by platelet-rich plasma and fibrin tissue adhesive at the histopathologic level were found together with no detected fistula. Among the study groups, there was no statistical difference for pharyngeal fistula development. This result may be obtained by the small number of animal experiments., Conclusion: These results shed light on the suggestion that platelet-rich plasma and fibrin tissue adhesive can be used in clinical studies to prevent pharyngocutaneous fistula., (Copyright © 2015 Elsevier Ireland Ltd.

Laryngopharyngeal reflux (LPR) is a type of reflux, seen with complaints of hoarseness, chronic cough, and globus sensation, different from gastroesophageal reflux disease (GERD). The aim of this study was to evaluate the awareness, knowledge, and practices of family physicians and trainees who were being trained in medical branches other than ENT and to determine the effective factors on decision making for diagnosis of this disorder. The study was designed as a two-stage study. At the first stage, a data collection tool, involving 29 questions by which the knowledge, awareness, and applications of the physicians about LPR would be determined, was developed with 12 specialists, using Delphi method. At the second stage, 101 family physicians replied the questionnaire online. For 45 trainees other than ENT, the questionnaire was filled face-to-face by one of the investigators. In patients admitted with complaints of hoarseness, lasting longer than 2 weeks, cough, lasting longer than 3 weeks, and globus sensation, the physicians considered LPR as the preliminary diagnosis with rates of 88.4, 82.2, and 62.8 %, respectively. 87.0 % of physicians, participating in the study, started treatment for reflux empirically in patients having complaints of hoarseness, chronic cough, and globus sensation; however, only 29.0 % of physicians prescribed this treatment for periods of 3 or 6 months. 69.9 % of physicians, participating in the study, made a diagnosis of reflux in general during their daily practices; only 6.9 % made the discrimination between LPR and GERD. Of all physicians, 27.9 % prescribed double-dose PPI or H2. [ABSTRACT FROM AUTHOR]
