BACKGROUND Moderate normobaric hyperoxia causes alveolar and vascular lung derangement in the newborn rat. Endogenous nitric oxide (NO), which promotes lung growth, is produced from the metabolism of L-arginine to L-citrulline in endothelial cells. We investigated whether administering L-citrulline by raising the serum levels of L-arginine and enhancing NO(More)
The sonographic evaluation of lymph nodes is based primarily on evaluation of their shape and size. Recently, however, the availability of high-frequency transducers has made consideration of internal structure possible. An important objective is to determine whether node enlargement is due to inflammatory or neoplastic processes. To determine the accuracy(More)
Necrotizing fasciitis (NF), a life-threatening rare infection of the soft tissues, is a medical and surgical emergency. It is characterized by subtle, rapid onset of spreading inflammation and necrosis starting from the fascia, muscles, and subcutaneous fat, with subsequent necrosis of the overlying skin. Once suspected, immediate and extensive radical(More)
BACKGROUND Negative pressure wound therapy (NPT) has achieved widespread success in the treatment of difficult wounds. However, its effects are but partially explored, and investigations mostly concentrated at the wound-dressing interface; a detailed histological description of the evolution of wounds under NPT is still lacking. MATERIALS AND METHODS(More)
BACKGROUND Treatment of bronchopulmonary dysplasia (BPD) remains as yet an unmet clinical need and recently stem cells have been proposed as a therapeutic tool in animal models. We investigated the role of amniotic fluid stem cells (AFS) in an adult rat model of hyperoxia lung injury. METHODS Fifty Sprague-Dawley rats were, at birth, randomly exposed to(More)
Intravascular papillary endothelial hyperplasia (IPEH), also known as Masson's tumour, is an uncommon benign vascular lesion characterized by small multiple, endothelial-lined, papillary structures with hyaline stalks. It appears to be a reactive condition involving excessive proliferation of endothelial cells in normal blood vessels or in vascular(More)
PURPOSE The use of polytetrafluoroethylene as bulking agent for the endoscopic treatment of vesicoureteral reflux in children has raised many concerns about the implant histocompatibility and the risk of migration of polytetrafluoroethylene particles. We report on 3 cases of long-term complications following subureteral polytetrafluoroethylene injection(More)
Apert syndrome (Acrocephalosyndactyly type I; AS) is a rare but well-known autosomal dominant disorder characterized by craniosynostosis, midface hypoplasia, bony/cutaneous syndactyly of fingers and toes as well as a variety of associated congenital anomalies involving the brain, heart, limbs and other organ systems. We report the case of a fetus with(More)
BACKGROUND No perfect solution yet exists for dermal fillers. The authors hypothesized that autologous dermis can be processed in an operator-friendly manner and adopted in selected patients as a filler, following the principle of replacing "like with like." METHODS The authors designed a prototype "cutting chamber" to morsel dermis into an injectable(More)
