Öğe Etiology and clinical features of acute renal failure in Turkey: A nationwide prospective study(SPRINGER, 2008) Duzova, A.; Bakkaloglu, A.; Kalyoncu, M.; Poyrazoglu, H.; Delibas, A.; Ozkaya, O.; Peru, H.[Abstract not Available]Öğe Henoch-Schonlein Nephritis: A Nationwide Study(KARGER, 2009) Soylemezoglu, O.; Ozkaya, O.; Ozen, S.; Bakkaloglu, A.; Dusunsel, R.; Peru, H.; Cetinyurek, A.Background/Aim: The aim of this retrospective study was to evaluate the presentation, clinical and pathological manifestations and outcome of the Henoch-Schonlein purpura (HSP) nephritis in children. Methods: Clinical and laboratory data of 443 children with HSP nephritis aged between 3 and 16 years from 16 pediatric nephrology reference centers were analyzed retrospectively. The biopsy findings were graded according to the classification developed by the International Study of Kidney Disease in Children (ISKDC). Results: Renal biopsy was performed in 179 of the patients with HSP nephritis. The most common presenting clinical finding in patients who were biopsied was nephrotic range proteinuria (25%) which was followed by nephritic-nephrotic syndrome (23.5%). The biopsy findings according to the ISKDC were as follows: class I: 8.3%; II: 44.1%; III: 36.3%; IV: 6.7%; V: 3.3%; VI: 1.1%. All of the patients who developed end-stage renal disease had nephritic-nephrotic syndrome at presentation. Of 443 patients, 87.2% had a favorable outcome and 12.8% had an unfavorable outcome. The overall percentage of children who developed end-stage renal disease at follow-up was 1.1%. Logistic regression analysis did not show any association of initial symptoms and histology with outcome. Conclusion: In the presented cohort, the presence of crescents in the first biopsy or presenting clinical findings did not seem to predict the outcome of HSP nephritis in children. We conclude that children with HSP nephritis even with isolated microscopic hematuria and/or mild proteinuria should be followed closely. Copyright (C) 2009 S. Karger AG, BaselÖğe How to manage intrauterine growth restriction associated with severe preeclampsia at 28-34 weeks of gestation?(2008) Gezginç, K.; Acar, A.; Peru, H.; Karataylı, R.; Çelik, Ç.; Çapar, M.Aim: To propose optimal management of intrauterine growth restriction (IUGR) cases associated with severe preeclampsia at 28-34 weeks of gestation. Methods: Two hundred pregnant women with severe preeclampsia associated with growth restricted fetuses were followed with doppler velocimetry of umbilical artery between 28-34 weeks of pregnancy. Patients were grouped according to indications for termination of pregnancy, first group consisted of severely affected doppler velocity waveforms (n:100) and the second group consisted of those whose cardiotocography and biophysic profile were unfavorable (n:100). Groups were compared according to perinatal outcomes (cesarean rates, gestational age at delivery, birth weight, Apgar scores and demand for intubation and perinatal deaths). Results: The diagnosis to delivery interval is significantly higher in the second group (p<0.05), whereas there was no significant difference between groups regarding gestational age at delivery and parity (p>0.05). Apgar scores were lower in the first group (p<0.05), and there was increased demand for intubation. Perinatal deaths were also lower in the second group (p<0.05). Cesarean rate was significantly lower compared with first group (p<0.05). Conclusion: Assessment of doppler velocimetry alone may not be enough at decision for termination of pregnancy, biophysic profile and cardiotocography should be added to confirm exact time for delivery of a premature fetus and to improve perinatal outcomes.Öğe The real diagnosis of cystinuria(KARGER, 2007) Elmaci, M.
