Renal vein thrombosis in patients with nephrotic syndrome: CT diagnosis

A retrospective evaluation of the computed tomography (CT) findings in 50 patients with the nephrotic syndrome was undertaken. In four patients with clinical manifestations of acute renal vein thrombosis (RVT) on initial examination, the diagnosis was confirmed by CT findings. Three patients had left RVT, one had right RVT, and all four had thrombus in the inferior vena cava (IVC) at the level of the renal veins. Of the remaining 46, otherwise asymptomatic patients, one had bilateral RVT, two had left RVT, and five had isolated IVC thrombus. The abnormalities noted on CT scans were widened renal vein(s) containing thrombus, thrombus in the IVC, renal enlargement, thickened Gerota fascia and formation of pericapsular venous collaterals, and an abnormal renal parenchymal enhancement pattern consisting of prolonged corticomedullary discrimination, delayed and/or persistent paraenchymal opacification, and delayed or absent pyelocalyceal visualization.     

Persistent growth faltering among Aboriginal infants and young children in northwest Australia: a retrospective study from 1969 to 1993

The objective was to examine long-term changes in the growth of Aboriginal infants and young children in the Kimberley region in the far northwest of Australia from 1969 to 1993. A retrospective analysis of anthropometric data (weight and length) routinely collected on 0–5-year-old children in 5-year cohorts from 1969 to 1993 was carried out. From 1974-78 to 1989-93 there has been a significant increase in mean birthweight (ANOVA p < 0.05). The percentage of low birthweight infants (<2500g) declined from 14% in 197983 to 10% in 1989-93 ( p < 0.001). There were no consistent improvements in the growth patterns of infants from birth to 60 months. All cohorts displayed pronounced growth faltering in weightforage and heightforage from 6 to 12 months of age and fell significantly below both the NCHS reference values and mean values for healthy breastfed infants. In conclusion, reductions in Aboriginal infant mortality and infectious disease rates over the past 20 years have not been accompanied by improved growth. The persistence of child malnutrition in these communities may warrant a shift in attention from disease treatment and prevention to a better understanding of nutritional influences, particularly weaning practices, during infancy and early childhood.     

Prediction of behavior management problems in children

Abstract – The aim of the present investigation was to study non-dental and dental background variables with a view to estimating their influence on behavior management problems by means of a structured interview and analyzing their separate and combined predictive power. The material consisted of a case group, 101 children aged 3–16 yr, referred for management problems to clinics of specialized pedodontics, and a control group, individually matched with the cases as regards age, sex, residential area, number of tooth surfaces restored, and dentist. The children or their parents were interviewed concerning background variables. Logistic regression was used for the analyses. Three non-dental variables turned out to be statistically significant as predictors ( P<0.05 ): problems on visiting a medical doctor, dental fear in the mother or father, and anxiety when meeting unfamiliar people. Management problems might be expected if one of these attributes is found. Four dental variables had significant predictive power: earlier problems on seeing a dentist, dislike of the dentist, not enough time to adjust to the dental situation, and fear of injection. However, none of these dental variables was found to have predictive power in 3–6-yr-olds, and none of them improved the predictive power of the three main non-dental variables.
