Value of real-time endobronchial ultrasound-guided transbronchial needle aspiration
No full textAim : The diagnostic value of real-time convex-probe endobronchial ultrasound (CP-EBUS)-guided transbronchial needle aspiration (TBNA) in mediastinal pathologies, and the factors influencing it are not clearly known. This study has been designed to examine factors affecting the efficacy and diagnostic value of CP-EBUS-TBNA. Methods : Patients (n = 321) with mediastinal mass or enlarged lymph node in the mediastinum, participated in this study, conducted between April 2007 and May 2009. Samples were obtained from the lesions using the TBNA method, with the guidance of CP-EBUS. Histopathologic (in all samples) and microbiologic (in 151 patients′ samples) evaluations were carried out. Biopsy using an appropriate surgical method was taken when the result of the TBNA procedure was nondiagnostic. Thirty-four patients were excluded from the analysis due to several reasons. The diagnostic efficacy of the procedure was analyzed in the remaining 287 patients. Results : The diagnostic rate was 92% (89.7% for the benign diseases and 92.6% for the malignant diseases (P = 0.59)). In granulomatous diseases, the rate was 96% for sarcoidosis and 79% for tuberculosis (P = 0.002). Patients in whom only one lymph node was sampled and in whom two or more lymph nodes were sampled had a diagnostic rate of 85% and 95%, respectively (P = 0.03). When left hilar nodes were sampled, a higher diagnostic rate was achieved (P = 0.01). Conclusions : CP-EBUS-guided TBNA has a high diagnostic rate. Sampling of at least two separate lymph nodes and the discovery of left hilar station in these lymph nodes increase the rate of diagnosis
Development of tubular knitted fabric-reinforced composite pipes
No full textIn literature, there exist many investigations about the application of knitted textiles as a reinforcement material in composites. Although majority of them are mainly centered on flat plates, tubular knitted fabric is used in current study to develop composite pipes. Produced composite pipes are subjected to axial compression before and after 5J impact test. Force-time and force-displacement curves are obtained, and compression stress is calculated according to wall thicknesses of the pipes. It is observed that the interlacing of yarns in knitted tubular fabric through the thickness direction increases the splitting toughness of composite pipes. Although the compression failure takes place as buckling in both nonimpacted and impacted composite pipes, damage propogation in the transverse direction is not observed. The results of the study are presented in detail.Ege UniversityEge University [2013-EAMYO-003]The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work was supported by Ege University under contract number 2013-EAMYO-003
Formulation and evaluation of intimate wash containing manuka oil and salix bark extract
No full textMost of the feminine hygiene products sold in the market contain heavy chemicals that damage the mucosa. The well-designed intim formulation cleans without damage, supports the flora, protects against dryness, and maintenances of balanced microflora. For this purpose, we designed formulations made with natural raw materials such as manuka oil and Salix alba bark extract and investigated their irritation potential and effectiveness. A healthy vagina is dominated by Lactobacillus that produces lactic acid, resulting in a characteristic acidic environment (pH 34), as it correlates with vaginal health by inhibiting the growth of bacteria and may also play a part in local immune defense. This new manuka oil- salix bark extract containing wash formulation was specifically formulated to achieve a formulation pH of 4.6-4.8 to be compatible with the normal skin pH range and to help maintain vulvovaginal skin homeostasis and provide protection against harmful bacteria. The formulation we designed was used by volunteers for 4 weeks and was found suitable in terms of gentle clean, refreshing feeling, shooting the skin, smell and irritation properties. None of the volunteers have experienced any side effects during product application. Our study findings further support other studies that have found that women who use intim wash attitudes and perceptions about hygiene.Tan-Alize, Inc.
