Bilateral giant abdominoscrotal hydroceles complicated by appendicitis

Abdominoscrotal hydrocele is a rare entity, with fewer than 100 cases reported in children. Bilateral abdominoscrotal hydroceles are even less common, with 14 cases reported in children. Various complications of abdominoscrotal hydrocele have been reported in the literature. We present a 4-month-old boy with bilateral giant abdominoscrotal hydrocele s who developed appendicitis apparently because of obstruction from the right hydrocele. We discuss the various imaging modalities used to establish the diagnosis and plan the operative approach.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46717/1/247_2005_Article_1572.pd

Effect of Perflubron-induced lung growth on pulmonary vascular remodeling in congenital diaphragmatic hernia

Congenital diaphragmatic hernia (CDH) involves lung hypoplasia and pulmonary hypertension (PH). Post-natal Perflubron ventilation induces lung growth. This phenomenon is called Perflubon-induced lung growth (PILG). However, it does not appear to ameliorate PH in CDH. We aim to determine the effect of PILG on pulmonary vascular remodeling in neonates with CDH and PH requiring extracorporeal membrane oxygenation (ECMO)

Isolation, growth and identification of colony-forming cells with erythroid, myeloid, dendritic cell and NK-cell potential from human fetal liver

The study of hematopoietic stem cells (HSCs) and the process by which they differentiate into committed progenitors has been hampered by the lack of in vitro clonal assays that can support erythroid, myeloid and lymphoid differentiation. We describe a method for the isolation from human fetal liver of highly purified candidate HSCs and progenitors based on the phenotypes CD38(-)CD34(++) and CD38(+)CD34(++), respectively. We also describe a method for the growth of colony-forming cells (CFCs) from these cell populations, under defined culture conditions, that supports the differentiation of erythroid, CD14/CD15(+) myeloid, CD1a(+) dendritic cell and CD56(+) NK cell lineages. Flow cytometric analyses of individual colonies demonstrate that CFCs with erythroid, myeloid and lymphoid potential are distributed among both the CD38(-) and CD38(+) populations of CD34(++) progenitors
