PURPOSE: The aim of this study was to assess the accuracy of computed tomography (CT) in the local staging of Wilms' tumor. METHODS: Twenty-six patients with unilateral, nonmetastatic Wilms' tumors were accrued over the period of 1990 through 1997. Preoperative CT staging was performed before surgical biopsy or excision. The abdominal CT images were reviewed and staged for local disease according to National Wilms' Tumour Study (NWTS) Group Staging V as either intrarenal disease (Stage I), local extrarenal extension amenable to complete local excision (Stage II), or advanced local disease (Stage III). Patients with metastatic (Stage IV) and bilateral disease (Stage V) were excluded from our study. Results were compared to histological findings. RESULTS: CT scan correctly staged 10 of 26 cases (38%) of Wilms' tumor. CT scan overstaged 12 of 16 (75%) localized renal disease (Stage I) and local extension (Stage II) tumors, and understaged 4 of 10 (40%) localized spread (Stage III) tumors. CONCLUSIONS: CT scan appears to have poor correlation to histological staging. Therefore, basing therapy solely on radiological imaging may lead to some patients receiving more intense therapy than necessary, whereas others do not receive sufficient therapeutic regimens. Histological assessment of the excised mass should remain the standard for staging Wilms' tumors.

A 10 year old girl presented with a massive femoral vein thrombosis associated with Mycoplasma pneumoniae pneumonia. Subsequently type I familial antithrombin III deficiency was diagnosed. It is suggested that prophylactic measures aimed at preventing thrombosis should be considered in acutely ill subjects with infection and familial thrombophilia.

The teeth of 44 children aged under 6 years who had been taking syrup medicines regularly for at least six months were compared with those of a control group of 47 children of similar ages. Dental disease was assessed by measuring dental caries, dental plaque, and gingivitis. The children who were receiving sucrose-based medicines had significantly more carious teeth and gingivitis. It is concluded that sucrose-based medicines continuously administered to children cause dental caries and gingivitis. Liquid medicines for children should be either unsweetened or sweetened with non-cariogenic substances.

Severe nutritional disorders, including kwashiorkor, marasmus, and rickets, were seen in four children and were due to parental food faddism, which should perhaps be regarded as a form of child abuse. All disorders were corrected with more normal diets and vitamin supplements. In view of the potentially serious consequences of restricted diets being fed to children, families at risk should be identified and acceptable nutritional advice given. When children are found to be suffering from undernutrition due to parental food faddism a court order will normally be a necessary step in providing adequate treatment and supervision.
