Abstract

Gi rifl: Kasım-Aralık 2009 tarihleri arasında influenza benzeri hastalık tanımına uyan vepnömoniyle gelişen, hastaneye yatırılan 68 olgu ile ilgili deneyimlerimizin paylaşılmasıamaçlandı.Gereç ve Yöntem: Kanıtlanmış pandemik 2009 influenza pozitif olgular ile negatifolgular klinik belirti ve bulgular, laboratuvar ve radyolojik görüntüleme sonuçları,hastanede ve yoğun bakımda yatış süreleri, almış oldukları tedaviler vekomplikasyonlar açısından karşılaştırıldı.Bulgular: Her iki grup arasında cinsiyet dağılımı açısından anlamlı bir fark saptanmadı.Pozitif olgularda 5 yaş üstü olgu sayısı aynı yaş grubundaki negatif olgulara göreanlamlı oranda yüksek saptandı p=0,004 . Pozitif olguların %78,8'inin, negatif olguların%68,8'inin altta yatan hastalığı vardı p=0,57 . Pozitif grupta ishal görülme oranı negatifgruptan anlamlı olarak yüksek saptandı p=0,02 . Mevsimsel influenza aşılanmaoranlarının düşüklüğü dikkat çekiciydi. Her iki grup arasında aşılanma oranlarıaçısından anlamlı bir fark saptanmadı p=0,99 .Sonuç: Hastalığın ciddiyeti pozitif ve negatif olgularda benzer seyretmiştir. Her ikigrupta da altta yatan hastalığı olanların oranının yükseldiği dikkat çekmektedir

Pandemic 2009 Influenza A H1N1 Infection in Children

Abstract

In tro duc ti on: The aim of this study is to share our experience of sixty-eight pediatric hospitalizations associated with influenza-like illness and pneumonia betweenNovember, 2009 and December, 2009.Materials and Methods: Clinical signs and symptoms, laboratory and radiological results,length of stay in hospital and intensive care unit, treatments and complications werecompared in laboratory confirmed pandemic influenza A positive and negative cases.Results: There was no significant difference in gender distribution between the twogroups. The number of positive cases in patients over 5 years of age were significantlyhigher than the same age group in negative patients p=0.004 . There were underlyinghealth conditions in 78.8% of the positive cases and in 68.8% of the negative cases p=0.57 . The incidence of diarrhea in positive group was significantly higher than in thenegative group p=0.02 . Low immunization rates of the seasonal influenza vaccine wereremarkable in each group. There was no significant difference in vaccination ratesbetween the two groups p=0.99 .Conclusions: The severity of the disease remained similar in patients with positive andnegative groups. In both groups, the high ratio of those having an underlying disease wasnoteworthy
