[False positive vascular increased uptake during cervico-thoracic radioiodine scan]

The total body radioiodine 131 scan is an important tool for the postoperative management of thyroid carcinomas. However, it has multiple false positives. Congenital or acquired vascular abnormalities such as ectasis or aneurism can be responsible for an increased uptake during the whole body radioiodine I[131] scan because of stagnation of the iodine and because of its delayed elimination when these malformations are present. We report the case of such a false positive

[Post infectious extracapillary glomerulonephritis: about 8 paediatric cases]

We reported 8 cases of post infectious extracapillary glomerulonephritis enrolled in the pediatrics department of Sousse during 10 years, diagnosed histologically. It is about 4 girls and 4 boys aged 3 at 13 years. Clinically, all patients had oedema and haematuria. Hypertension was present in 6 cases; 7 children were anuric. All patients have renal failure, associate at nephrotic syndrome in 6 cases. The ASLO titres are elevated in 7 patients. Renal biopsy showed diffuse crescents in 6 cases and circumferential cresents in 3. 7 patients well treated by corticoids and immunosupresseurs. The outcome is good in 4 cases
