Percutaneous abscess drainage is a valuable procedure in pediatric patients with Crohn's disease presenting with pelvic or abdominal abscesses (or both). It improves the general status of the patient and allows a less invasive and easier subsequent surgical procedure. Percutaneous abscess drainage should be performed before definitive treatment.

The prognosis of prenatally detected G is excellent despite the frequency of small bowel atresia (67%) in the group with postnatal complications. Meconium peritonitis before 20 weeks of gestation and/ or asymmetrical bowel dilatation also appear to be indicators of atresia (2/4, 50%) or high morbidity (3/4, 75%).

Background/Aims: To assess whether the presence of certain findings on thyroid ultrasonography (US) correctly diagnoses malignancy even when a fine-needle aspiration biopsy (FNAB) suggests a benign lesion. Methods: We reviewed the charts of 35 children and adolescents with a thyroid nodule who had had an US and a FNAB, and for whom final pathology was available. Results: The global accuracy of FNAB was 83%, with a sensitivity of 75% and a specificity of 94%. 14 FNABs suggested malignancy (40%), only 1 of which was a false positive (7%). By contrast, 5 of the 21 FNABs suggesting benign lesions were false negatives (24%). These 5 cases had US findings suggestive of malignancy. When FNAB suggested a benign lesion, US had a good sensitivity (80%) but a poor specificity and accuracy (50 and 57%, respectively); its negative predictive value was 90% and its positive predictive value 36%. Conclusions: US complements FNAB in the evaluation of thyroid nodules in children. A more aggressive approach is warranted in children with a thyroid nodule and a benign FNAB if US findings suggest malignancy.
