Background: Acute gastroenteritis is responsible observed in all age groups, especially infants and children. The etiology and clinical course of acute gastroenteritis may vary with age and etiological agents. In developing countries, the morbidity and mortality associated with infectious diarrhea is higher in children younger than five-years-of-age. Objectives: The aim of this study was to determine the prevalence and seasonal distribution of the major agents of acute gastroenteritis in children who were admitted to a Turkish university hospital pediatric emergency unit during 2009. Patients and Methods: Seasonal distribution within a one year period and quantitative distribution were analyzed with demographic data and laboratory findings. A total of 644 subjects were enrolled in the study, with a mean age of 4.14 years. Pathogens were detected in 183 (28.4%) stool samples in children less than 16 years, admitted with acute gastroenteritis. Results: Pathogens were detected in 184 (28.4%) stool samples. The age distributions of the cases were 0 - 24 months (n = 59), 2 - 5 years (n = 100), and > 5 years (n = 25). The detection rate of rotavirus, norovirus and adenovirus were; 12.7% (75/588), 9.8% (51/520) and 4.9% (28/575), respectively. Bacterial agents were detected in 36 cases. The main agent was norovirus in the 0 - 24 months group (n = 25, 42.4%), and rotavirus for ages 2 - 5 years (n = 43, 43%) and > 5 years. On the monthly distribution, cases of rotavirus were found to be more frequent in the first four months of the year. Discussion: Viruses were the major pathogens in all age groups. Norovirus was the leading pathogen in the first two years. For the age groups 2 - 5 years and 6 - 16 years, rotavirus was the major pathogen.

Cocukluk caginda yabanci cisim yutulmasi oldukca sik gorulen bir durumdur. Bazen toplu igne, kurdan ya da ucu acik cengelli igne gibi keskin yabanci cisimler de yutulmaktadir. 13 aylik erkek bebek, cengelli igne yutma suphesiyle acil servisimize getirildi. Alti saat once bebegin sag omzundaki ignenin kayboldugunun fark edilmesi uzerine goturuldugu ozel bir hastanede cekilen duz batin grafisinde, cengelli ignenin ucu acik olarak pilorda oldugu gorulerek bir universite hastanesine yonlendirildi. Pediatrik acil servisimize basvurdugunda tekrarlanan batin grafisinde ucu acik cengelli ignenin duodenumun ilk kismina ilerledigi gozlemlendi. Hasta gozlem amaciyla hastaneye yatirildi. Yirmi saat sonra cekilen kontrol grafisinde cengelli ignenin cikan kolonda oldugu izlendi. Bebege oral beslenme baslandi ve ailesine diski kontrolu yapilmasi icin egitim verilerek poliklinik kontrolune cagrildi. Ertesi gun aileyle yapilan telefon gorusmesinde, ucu acik cengelli ignenin spontan olarak, diskiyla atildigi ogrenildi. Cengelli igne yutan bebek ve cocuklar, endoskopi ve/veya cerrahi yapilmadan sadece klinik olarak komplikasyonsuz takip edilebilir. Yazimizda, cengelli igne gibi keskin yabanci cisim yutulmasina dikkat cekmek amaciyla, spontan olarak diskiyla atilan acik cengelli igne yutmus olan bebek rapor edilmistir.

ÖZET Amaç: Bu çalışmada, ebeveynlerin çocuk oto güvenlik koltuğu (ÇOGK) kullanım oranları ve bu konu hakkındaki bilgi düzeyleri değerlendirildi. Gereç ve Yöntemler: Bu çalışmaya, çocuk polikliniğine başvuran 250 ebeveyn alındı. “Sosyodemografik özellikler”, “çocuk oto güvenlik koltuğu (ÇOGK) kullanımını etkileyen faktörler”, “ÇOGK kullanımı” ve “ÇOGK kullanımı ile ilgili bilgiler” hakkındaki 22 soruluk anket, yüz yüze görüşme yöntemiyle uygulandı. Varyans analizine yönelik olarak t-test, sürekli değişkenler için iki ortalama arasındaki farkın önemlilik testi kullanıldı. Kesikli ve kategorik değişkenlere yönelik olarak ki-kare testi uygulandı. Bulgular: Ebeveynlerin %93.6’sı ÇOGK hakkında bilgi sahibi olup, %80.8’i ÇOGK kullanıyor, %12.8’i ise kullanmıyordu. Gelir düzeyi yüksek olan ebeveynlerin ÇOGK kullanım oranı yüksekti (p < 0,05). Ebeveynlerin eğitim durumu da ÇOGK kullanımı ile doğru orantılıydı (p < 0,05). ÇOGK’nin doğru yerleşimini ailelerin %98’i biliyordu. ÇOGK’nu çocuğun yaşına uygun olarak değiştiren ebeveynlerin oranı %53.5 idi. Yaşa uygun olarak değiştirilmesi gereksinimi hakkındaki bilgi düzeyi geliri orta ve iyi düzeyde olanlarda ve babanın eğitimi yükseköğrenim düzeyinde olanlarda daha yüksekti (p < 0,05). ÇOGK kullanmanın kanuni zorunluluk olduğunu bilenlerin oranı %88.6 idi. ÇOGK hakkındaki bilgiyi ebeveynlerin %37’si internetten, %33’ü medya yoluyla, %27’si ise çevresindeki kişilerden edinmişti. Hekim tavsiyesiyle bilgi sahibi olanların oranı oldukça düşüktü (%3). Sonuç: Ebeveynlerin eğitim ve gelir düzeylerindeki artış ÇOGK kullanımını artırarak çocuk yaralanma ve ölümlerini azaltabilir. Tıp öğrencilerine tıp eğitiminde ve ebeveynlere rutin çocuk vizitlerinde çocuk güvenliği ve ÇOGK kullanımı hakkında bilgi verilmelidir CAYD 2014;1(2):87-95. Anahtar Kelimeler: Aile, bilgi düzeyi, çocuk oto güvenlik koltuğu, trafik kazaları

Background and Aims Noroviruses are one of the common causes of acute gastroenteritis and have a great impact on child health. The aim of this study was to determine the prevalence of Norovirus in children with acute gastroenteritis in 2009 and 2010. Methods Fecal samples were collected from children under 16 years of age who were suffering from acute gastroenteritis. All the children were referred to Yeditepe University Hospital, located in Istanbul. Norovirus was detected using immunochromatography. Results Norovirus infection was detected in 112 of the 1027 collected samples (10.9%). Most of the positive cases were between 1 and 24 months of age (n=75, 67%). The rate of norovirus infection peaked in winter in 2010 (in winter and spring: n=57, 92%), however, the rates were not significantly different between seasons in 2009 (in winter and spring: n=26, 52%, in summer: n=23, 46%). We did not detect any positive cases in late summer and autumn in 2010. Conclusions This study improves our epidemiological knowledge of the prevalence of Norovirus in Istanbul. Immunochromatography is preferable, that provides rapid diagnosis. The prevalence of Norovirus is similar but seasonal distribution is different between two years. Most of the cases were < 24 months of age. Because this virus is transmitted by contaminated food or water, and transmitted by personal contact, we recommend improved training in hygiene to reduce the incidence of Norovirus infection in children. Like Rotavirus, Norovirus vaccine can be developed to prevent infection.

Background Meropenem is a carbapenem antibiotic, has a broad spectrum of antimicrobial activity. Valproate is widely used in the treatment of epileptic seizures in children. In last years, low serum concentrations of valproate were reported in children and adults receiving concomitant administration with meropenem. We present an interaction of meropenem with valproate in an epileptic child, leading to seizure exacerbations owing to the rapidly-lowering of serum valproate concentration. Case Report This report describes a 14-year-old epileptic girl inpatient who received concurrent treatment with meropenem and valproate for the treatment of lobar pneumonia, pleuresia and epilepsy, respectively. In this patient, an increase of seizure frequency and somnolence were observed after addition of meropenem on the treatment, and a rapid decline of valproate serum concentrations was observed after two dose meropenem. This event was the most likely cause of increased seizure frequency. The dosage of valproate was increased and meropenem was stopped. Two days later, the seizures stopped. Five days later, the serum valproate concentrations increased to three fold and four week later, they increase to therapeutic levels. The seizures were considered to be probably related to the concurrent administration of meropenem and valproate. Conclusion To avoid drug interaction that reduces the serum concentration of valproate, meropenem should not be used in epileptic patients using valproate for the treatment of epilepsy. If concominant administration is essential, serum valproate levels should be monitorized frequently.
