Prenatal imaging features and postnatal outcomes of isolated fetal duplex renal collecting system: a systematic review and meta-analysis.
OBJECTIVES: To perform a systematic review of studies reporting the outcome of fetuses with a prenatal diagnosis of isolated duplex collecting system (DCS). METHODS: Inclusion criteria were studies reporting the outcome of fetuses with a prenatal diagnosis of isolated DCS, defined as DCS not associated with other major structural anomalies at the time of diagnosis. The outcomes observed were: imaging features of DCS on prenatal ultrasound, associated anomalies detected exclusively at prenatal follow-up ultrasound and at birth, abnormal karyotype, symptoms at birth [including vesicoureteral reflux (VUR), urinary tract infections (UTI)], need for and type of surgical approach, complications after surgery and accuracy of prenatal ultrasound in correctly identifying this anomaly. RESULTS: Eleven studies (284 fetuses with a prenatal diagnosis of DCS) were included. On ultrasound, DCS was associated with ureterocele in 70.7% and with megaureter in 36.6% of cases. Worsening of pelvic/ureteric dilatation was reported to occur in 41.3% of fetuses. At birth, 4.3% of fetuses affected by DCS showed associated renal anomalies. After birth, VUR and UTI presented in 51.3% and 21.7% of children respectively, while 33.6% required surgery. Prenatal diagnosis of DCS was confirmed in 90.9% of included cases. CONCLUSION: DCS diagnosed prenatally is associated with a generally good outcome. Prenatal ultrasound has a good diagnostic accuracy, while detailed post-natal assessment is required in order to identify associated renal anomalies. This article is protected by copyright.

Infliximab in paediatric inflammatory bowel disease
AbstractInfliximab has been widely used in paediatric Crohn's disease, mainly in luminal and fistulous disease refractory to standard treatment and for extraintestinal manifestations. Moreover, there is growing experience with its use in refractory ulcerative colitis. Infliximab has shown similar efficacy and safety in children as in adult population. It is postulated that its early use in paediatric inflammatory bowel disease, as a bridging treatment until the onset of action of other immunomodulators, could reduce the use of steroids and change the natural history of the disease as well. The effect of infliximab on mucosal healing could also contribute to the normal growth and sexual maturation in these patients
Inflammatory bowel disease in children and adolescents in Italy: data from the pediatric national IBD register (1996-2003).
Abstract
BACKGROUND:
The purpose was to assess in Italy the clinical features at diagnosis of inflammatory bowel disease (IBD) in children.
METHODS:
In 1996 an IBD register of disease onset was established on a national scale.
RESULTS:
Up to the end of 2003, 1576 cases of pediatric IBD were recorded: 810 (52%) ulcerative colitis (UC), 635 (40%) Crohn's disease (CD), and 131 (8%) indeterminate colitis (IC). In the period 1996-2003 an increase of IBD incidence from 0.89 to 1.39/10(5) inhabitants aged <18 years was observed. IBD was more frequent among children aged between 6 and 12 years (57%) but 20% of patients had onset of the disease under 6 years of age; 28 patients were <1 year of age. Overall, 11% had 1 or more family members with IBD. The mean interval between onset of symptoms and diagnosis was higher in CD (10.1 months) and IC (9 months) versus UC (5.8 months). Extended colitis was the most frequent form in UC and ileocolic involvement the most frequent in CD. Upper intestinal tract involvement was present in 11% of CD patients. IC locations were similar to those of UC. Bloody diarrhea and abdominal pain were the most frequent symptoms in UC and IC, and abdominal pain and diarrhea in CD. Extraintestinal symptoms were more frequent in CD than in UC.
CONCLUSIONS:
The IBD incidence in children and adolescents in Italy shows an increasing trend for all 3 pathologies. UC diagnoses exceeded CD

Natural resource risk and cost management in environmental restoration: Demonstration project at the Savannah River Site
The US Department of Energy (DOE) is both a trustee for the natural resources present on its properties and the lead response agency under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). As such, DOE is addressing the destruction or loss of those resources caused by releases of hazardous substances from its facilities (DOE 1991) and collecting data to be used in determining the extent of contamination at its facilities, estimating risks to human health and the environment, and selecting appropriate remedial actions. The remedial investigation/feasibility study (RI/FS) process is used to investigate sites and select remedial actions. A Natural Resource Damage Assessment (NRDA) process may be used to determine whether natural resources have also been injured by the released hazardous substances and to calculate compensatory monetary damages to be used to restore the natural resources. In FY 1994, the Savannah River Site (SRS) was chosen to serve as a demonstration site for testing the integrated NRDA framework and demonstrating how NRDA concerns might be integrated into the environmental restoration activities of an actual site that is characteristically large and complex. The demonstration project (1) provided a means to illustrate the use of complex analyses using real information on the specific natural resources of the SRS; (2) served as a vehicle for reinforcing and expanding the SRS staff`s understanding of the links between the NRDA and RI/FS processes; (3) provided a forum for the discussion of strategic issues with SRS personnel; and (4) allowed the refining and elaboration of DOE guidance by benchmarking the theoretical process using real information and issues
