Renal venous thrombosis in an infant with predisposing thrombotic factors: color Doppler ultrasound and MR evaluation.

We report a case of a neonate with hereditary thrombophilia presenting with renal venous thrombosis (RVT). Early color Doppler findings of RVT were lacking venous flow, and the arterial diastolic flow was reversed. This very high-resistance arterial flow is for the first time described in neonatal RVT. Magnetic resonance imaging showed low signal intensity of the renal pyramids on T1- and T2-weighted images, suggesting acute hemorrhage. After intravenous contrast injection, persistent cortical enhancement was observed along with lack of medullary enhancement. Despite the progressive reestablishment of some venous drainage, the kidney showed atrophy and loss of function.

Neonatal bacteraemia: a population-based study.

The aims of this study were to explore the incidence of neonatal bacteraemia and identify the risk factors among neonatal intensive care unit (NICU) patients. The study included 3339 neonates admitted to the NICU of Ioannina University Hospital, North-Western Greece, during the 10-y period 1989-98. Logistic regression was used to assess the contribution of different risk factors to bacteraemia. A diagnosis of bacteraemia was made in 90 neonates (2.7%), 10 of whom (11%) died. Gram-negative bacilli, coagulase-negative Staphylococci and Streptococci were the most common pathogens: 42%, 34% and 17%, respectively. Premature rupture of membranes was the main risk factor for early-onset sepsis (relative risk 6.28) and respiratory distress syndrome was the main risk factor for late-onset sepsis (relative risk 5.70). The relative size of neonates for their gestational age did not appear to influence the risk of infection. Case fatality was higher for early- than for late-onset sepsis (relative risk 6.59). In conclusion, certain conditions were confirmed to predispose patients to neonatal bacteraemia; neonatal morbidity and mortality can be reduced by intervening to control these predisposing factors.
