Öğe Reliability of Plasma Pseudocholinesterase and Erythrocyte Acetylcholinesterase Activity in the Diagnosis of Hirschsprung's Disease(1994) Dilsiz, A.; Çağlayan, F.; Koçyiğit, A.; Dilek, O. N.; Köseoğlu, B.The determination of plasma pseudocholinesterase (PChE) and erythrocyte acetylcholinesterase (AChE) activity has been suggested as a diagnostic aid for Hirschsprung's disease (HD). In this study plasma PChE and erythrocyte AChE activity was measured in patients in whom the diagnosis of HD was confirmed (n=9) and in patients in whom the diagnosis of HD was excluded (n=12). There was no significance in PChE and erythrocyte AChE in both groups. This study suggests that PChE and erythrocyte AChE are not reliable diagnostic aid for HD.Öğe Ultrasound-Guided Percutaneous Drainage in the Treatment of Children with Hepatic Hydatid Disease(SPRINGER VERLAG, 1997) Dilsiz, A.; Açıkgözoğlu, Saim; Günel, E.; Dağdönderen, L.; Köseoğlu, B.; Gündoğan, A. H.The present study was designed to establish the safety and efficacy of ultrasound-guided percutaneous drainage in the treatment of hepatic hydatid cysts In children. A total of 14 cysts in eight patients were drained under aseptic conditions and continuous ultra sound guidance. An 18-G needle was used for puncture and silver nitrate solution as the scolecoidal agent. All procedures were successful. During follow-up, repeated ultrasound examinations revealed a progressive decrease in cyst size and an alteration in the cyst echopattern. None of the patients had a rise in hydatid antibody titer. There were no immediate or late complications. We conclude that the safety and efficacy of ultrasound-guided percutaneous drainage are satisfactory for the treatment of hepatic hydatid cysts in children.
