Over restrictive elimination of foods in children with foodallergy

Background. Previous studies demonstrated critical deficits in diagnosis and management of childhood foodallergy (FA), and recent developments in FA research support adopting a proactive approach in FA management.Our objective was to describe FA knowledge and management patterns of pediatricians.Method. We applied a 24-item survey to 170 general pediatricians, pediatric allergists and pediatricgastroenterologists practicing in Turkey.Results. Some IgE-mediated symptoms of FA such as cough, urticaria, wheezing and anaphylaxis were falselyrecognized as symptoms of non-IgE-mediated FA by 30%, 29%, 25% and 19% of the participants, respectively.By contrast, 50% of the participants falsely recognized bloody stool, a finding of IgE-mediated FA. Mostfrequently and least frequently used diagnostic tools were specific IgE (30.5%) and oral food challenge test(1.7%), respectively. Maternal diet restrictions and infant diet restrictions were advised by 82% and 82%,respectively. Percentages of physicians eliminating only 1 food were 21%, 19%; 2 foods were 15%, 11%; 3 foodswere 7%, 8%; 4-5 foods were 8%, 11%; 5 to 10 foods were 21%, 26%; and >10 foods were 28%, 25% from thematernal and infant diet, respectively. Cow’s milk, cheese, butter, yoghurt, baked milk products and hen’s eggwere the most commonly restricted items.Conclusion. Overall, FA knowledge of pediatricians was fair. Pediatricians utilize an overly restrictive approachwhen advising diet eliminations in FA. Recent developments favor a more proactive approach to induce immunetolerance and need to be encouraged in pediatric clinical practice. Future educational efforts should focus onemphasizing the deleterious effects of injudicious and extensive eliminations

DEVELOPMENT OF HALOGEN-FREE FLAME RETARDANT ACRYLONITRILE BUTADIENE STYRENE (ABS) BASED COMPOSITE MATERIALS

The high performance properties of Polyamide 6 and Polyamide 6.6 thermoplastics create aserious area of use in various sectors such as automotive, railway, textile, construction andelectronics. High mechanical strength performance, easy processing properties and highthermal resistance performance are the advantages of this group of thermoplastics. Highmoisture absorbency, low dimensional stability, low temperature impact strength, and beingeasily flammable can be considered among the disadvantages of these thermoplastics.Structural disadvantages are also reflected as a problem in the final products and limit the wideusage areas of polymers. In recent years, acrylonitrile-butadiene-styrene (ABS) has become awidely used thermoplastic polymer due to its good mechanical properties, high chemicalresistance, and easy process applicability. ABS also has some disadvantages that limit its usageareas. Natural flammability and toxic gas emission together with dense smoke are among thesedisadvantages. Increasing the flammability performance of ABS by using halogenated additivesand antimony synergists has been a very common method in the past. However, with theawareness of environmental sensitivity, the use of halogen-containing additives has beenseverely limited over time. Therefore, the development of halogen-free ABS compositematerials with improved flame retardant properties is a serious problem nowadays. A twinscrew extruder and an injection molding machine were used in this study. ABS –basedcomposites were prepared by adding phosphinate and polyphosphate halogen-free flameretardant additives at a total of 20, 25, 30% by weight in the ABS matrix. The characterizationand performance studies of the produced samples were evaluated with the test results carriedAEGEAN SUMMIT 4th INTERNATIONAL APPLIED SCIENCES CONGRESSABSTRACT BOOK ISBN: 978-625-7341-89-9 www.egekongresi.org Page | 20out within the framework of certain standards such as UL 94 and IEC 60695-2-12.
