Congenital absence of portal vein is a rare malformation. To date, 16 cases have been reported – all in association with other anomalies, i.e. benign or malignant hepatic neoplasms in 6 cases and cardiac malformations in 12. This case report described a girl with congenital absence of portal vein, focal nodular hyperplasia of the liver and cystic kidney(More)
Nodular regenerative hyperplasia (NRH) of the liver is a condition of unknown origin, rarely occurring in children, usually accidentally discovered, described in association with a variety of clinical conditions and drugs. Confusion with other types of hepatic masses may pose a problem and for this reason NRH is considered a "tumor-like lesion."(More)
Urokinase is an enzyme with a fibrinolytic effect that facilitates pleural empyema drainage through a chest tube. The aim of this study was to assess the risk of pneumothorax, the need for pleural debridement surgery, the persistence of fever, and the number of days in hospital in a group of children with parapneumonic pleural empyema treated with(More)
In the surgical repair of congenital abdominal-wall defects (AWD), the ready availability of a non-immunogenic and non-prosthetic biomaterial that could guide the regeneration of normal tissue is a fascinating possibility. Biomaterials are already in use, but in our experience, an acellular matrix (ACM) can stimulate exact regeneration of the absent tissue.(More)
The article describes a rare case of congenital A-V fistula between descending aorta and hemiazygos vein in a 9-year old girl. Differential diagnosis in these cases is difficult and only sonography and angiography can lead to a correct diagnosis. The recent literature of this subject is reviewed.
Urethral reconstruction following failed hypospadias repair or post-traumatic chronic stricture requires adequate amounts of tissue. Many surgical techniques utilizing different types of biological tissues have been attempted: (a) vascularized skin flaps from the prepuce, scrotum or penile shaft; (b) full-thickness free skin grafts; (c) vesical or buccal(More)
AIM In paediatric and adult patients with neurogenic bowel, transanal irrigation (TAI) of the colon has gained popularity due to the introduction of a specifically designed device. The aim of this pilot study was to present the results of TAI using the Peristeen(®) TAI system in a group of paediatric patients with anorectal malformation (ARM) and congenital(More)
We report the case of a 14-month-old child with Kasabach-Merritt Syndrome, due to a giant liver hemangioma. The therapeutic approach consisted of peripheral transcatheter embolisation of the right hepatic artery with Ivalon microspheres without the addition of thrombogenic material. This procedure brought to a sensible permanent reduction of the size of the(More)
PURPOSE We describe 3 cases of testicular cystic dysplasia that were diagnosed only by sonography to avoid an invasive approach. MATERIALS AND METHODS Three patients 5, 8 and 12 years old, respectively, had increased testicular volume and/or intermittent pain. Sonographic examination of the testis by high frequency (7.5 mHz.) probes showed the typical(More)
In pediatric kidney transplantation, the effect of inadequate nephron dosing on graft survival remains undetermined. The aim of this study was to assess the use of D/R BSA, as a reliable indicator of adequate nephron dosing, and eventually a tool to optimize pediatric graft allocation. Following Institutional Review Board approval, we reviewed deceased(More)
