Abstract

Aim: The aim of this study was to establish serum sistatine C urine beta;2 microglobulin gluthatione S transferase pi; and N acetyle beta; D glucosaminidase levels in order to evaluate the effect of total parenteral nutrition on renal function in premature infants In addition we aimed to compare the renal functions between premature infants receiving total parenteral nutrition and control groups receiving enteral feeding Material and Method: A hundred four premature infants with a gestational age between 28 and 34 weeks were included in the study The parenteral nutrition group consisted of 50 infants male female; 23 27 and mean weight 1258 plusmn;212 3 g and the enteral nutrition group consisted of 54 infants male female; 20 34 and mean weight 1608 plusmn;206 1 g In the parenteral nutrition group; total parenteral group nutrition was initiated on the 3rd day in the enteral nutrition group minimal enteral nutrition was started on a mean of 6 3 plusmn;2 4 days and total enteral nutrition was started on a mean of 24 5 plusmn;6 3 days Breastmilk was given orally or by orogastric nasogastric tube at first day of life in the enteral group On the 3rd and 30th day of life blood samples of all patients were obtained for evaluating biochemical parameters and cystatin C and urine samples were obtained for evaluation of N acetyl beta; D glucosaminidase gluthatione S transferase pi; beta;2 microglobulin sodium creatinin levels density and pH of the urine The study was approved by the ethics commite 2008 16 Results: When we compared the patients who received total parenteral nutrition and enteral nutrition on the 3rd and 30th days serum cystatin C urinary beta;2 microglobulin gluthatione S transferase pi; and N acetyl beta; D glucosaminidase excretions were similar on the 3rd day however were significantly higher on the 30th day in samples of the patients receiving total parenteral nutrition p lt;0 05 for each parameter on each day Conclusions: This study shows that total parenteral nutrition in premature infants can have adverse effects on glomerular and tubular functions of the kidney which can be manifested at an early time with cystatin C beta;2 microglobulin gluthatione S transferase pi; and N acetyl beta; D glucosaminidase Turk Arch Ped 2012; 47: 247 52

Zon 1 prematürite retinopatisi olan hastaların diod lazer fotokoagülasyon ile tedavi sonuçları

Abstract

Amaç: Üçüncü basamak sağlık hizmeti veren üniversite hastanesi kliniğimizde Zon 1 prematürite retinopatisi olan hastaların diod lazer fotokoagülasyon DLF ile tedavi sonuçlarını bildirmek. 

Gereç ve Yöntem: Cerrahpaşa Tıp Fakültesi Retina Birimi rsquo;nde Haziran 2007 ile Aralık 2010 tarihleri arasında prematürite retinopatisi için erken tedavi The Early Treatment for Retinopathy of Prematurity Study = ETROP ölçütlerine göre eşik öncesi zon 1 tanısı alarak ve yine ETROP ölçütlerine uygun olarak diod lazer fotokoagülasyon uygulanmış 257 yeni doğanın 452 gözüne ait veri dosyaları geriye dönük olarak incelendi Anatomik ve yapısal başarı prematürite retinopatisinin gerilemesi ve makulanın yatışık olması arka zon 1 grup A ve ön zon 1 grup B için ayrı ayrı değerlendirildi. 

Bulgular: Grup A rsquo;da ortalama doğum ağırlığı 1120 2 g aralık 490 2500 g olup ortalama doğum haftası ise 28 2 hafta aralık 22 35 hafta idi Grup B rsquo;de ise ortalama doğum ağırlığı 1128 9 g 560 1930 ve ortalama doğum haftası 28 4 hafta 24 34 idi Arka zon 1 hastalarda 98 15 ön zon 1 hastalarda ise 98 65 başarı elde edildi. 

Çıkarımlar: Zon 1 prematürite retinopatisi yüksek riskli hastaları kapsar Bu hastalığın lsquo;eşik öncesi rsquo; dönemde diod lazer ile tedavisi etkin ve güvenli bir tedavidir Ülkemizde yüksek doğum ağırlıklı erken doğmuş bebeklerde zon 1 prematüre retinopatisinin görülmesi perinatal bakım hizmetlerinin yeniden gözden geçirilmesi ile azaltılabilir.
