Publication Open Access Can allergy patch tests with food additives help to diagnose the cause in childhood chronic spontaneous urticaria?(2020-01-01T00:00:00Z) Ozceker, Deniz; Dilek, Fatih; Yucel, Esra; Tamay, Zeynep; ÖZKAYA, EMİN; Guler, Nermin; ÖZKAYA, EMİNIntroduction: Chronic spontaneous urticaria (CSU) is characterized by the onset of symptoms which are not induced by specific triggers, but are rather spontaneous. A considerable number of patients report that foods or food additives might be responsible for their chronic urticaria.Publication Metadata only The Association Between Paranasal Mucous Retention Cysts and Allergic Sensitization(2021-01-01T00:00:00Z) USTABAŞ KAHRAMAN, Feyza; YAZICI, MEBRURE; BÜYÜKPINARBAŞILI, NUR; Soylu, Nihal; İŞCAN, AKIN; ÖZKAYA, EMİN; USTABAŞ KAHRAMAN, FEYZA; YAZICI, MEBRURE; BÜYÜKPINARBAŞILI, NUR; İŞCAN, AKIN; ÖZKAYA, EMİNObjective: Although there is no consensus regarding the etiology of paranasal mucous retention cysts (MRCs) in the literature, several studies suggest an allergic etiology. This study aimed to investigate a potential association between paranasal MRCs diagnosed with MRI scans and allergic sensitization in the pediatric population.Publication Metadata only Human paraoxonase-1 activity in children with acute bronchiolitis Akut bronşiolitli çocuklarda human paraoksonaz-1 aktivitesi(2020-01-01T00:00:00Z) ERENBERK, UFUK; Kahraman, Feyza Ustabaş; Özkaya, Emin; NURSOY, MUSTAFA ATİLLA; Demir, Ayşegül Doğan; TÜREL, Özden; ERENBERK, UFUK; ÖZKAYA, EMİN; NURSOY, MUSTAFA ATİLLA; TÜREL, ÖZDEN© 2020, Galenos.

We aimed to investigate serum PON1 activity in children with acute bronchiolitis. MATERIALS and METHODS: A total of 29 children aged between 3-21 months with acute bronchiolitis and 35 age-matched healthy controls were included in the study. Bronchiolitis patients were further classified as mild (65%) and moderate (35%). Paraoxonase and arylesterase activities of PON1 were compared between patients with acute bronchiolitis and the control group. RESULTS: Paraoxonase activity of children with acute bronchiolitis was lower than healthy controls but the difference was not significant (127.53 ± 64.17 U/L versus 153.95 ± 74.40 U/L) (p=0.13). Arylesterase activity was significantly decreased in children with mild and moderate bronchiolitis in comparison to the control group (142.43± 56.60 kU/L and 103.70± 26.03 kU/L versus 201.09± 57.26 kU/L) (p<0.001). CONCLUSIONS: Serum PON1 activity was lower in children with acute bronchiolitis compared to controls. Increasing antioxidant capacity may be an effective means of therapy in viral induced lung disease.
