Historically, some dressings used in exomphalos major were associated with toxicity. These have been abandoned in favor of safer dressings. Silver toxicity has not been described following the use of silver dressings in infants. We, however, found disconcerting serum silver levels in 2 consecutive patients during treatment with silver salt containing dressings.

Infants with left-sided congenital diaphragmatic hernia (CDH) are subject to possible intrahepatic placement of the umbilical venous catheter (UVC) during catheterization. A left-sided CDH containing the left lobe of the liver is subject to repositioned anatomy of the umbilical vein, ductus venosus, and hepatic vasculature. ⋯ The patient underwent successful repair of the diaphragmatic defect and is a healthy youngster without complication from CDH or extravasation of the liver capsule. Cannulation of the hepatic vasculature cannot be ruled out with radiograph in infants with left-sided CDH.

Median arcuate ligament syndrome (MALS) is a rare disorder resulting from luminal narrowing of the celiac artery by the insertion of the diaphragmatic muscle fibers. Surgical management entails division of the median arcuate ligament with or without celiac artery reconstruction. We are presenting an interesting case of a 16-year-old girl with postprandial abdominal pain and weight loss. ⋯ The postoperative course was uneventful, and she was dismissed on postoperative day 2. She remains asymptomatic at 12-months follow-up. This represents the first report of a transperitoneal laparoscopic approach to MALS in an adolescent and the first report of a familial/generational component to MALS.

Case Reports
Costal osteochondroma causing pneumothorax in an adolescent: a case report and review of the literature.
Costal osteochondroma is a rare but important condition to recognize because of the possibility of serious consequences if not diagnosed and treated promptly. Patients can present with numerous complications, including hemothorax, pneumothorax, nervous or vascular impingement, and fracture. ⋯ A computed tomographic scan of the chest revealed the cause to be a costal exostosis of the anterior fifth rib. The lesion was excised using video-assisted thoracoscopic surgery, which has become an increasingly popular method for treating these lesions, causing significantly less morbidity and allowing for a faster recovery than a major thoracotomy.

Comparative Study
Limb ischemia after common femoral artery cannulation for venoarterial extracorporeal membrane oxygenation: an unresolved problem.
Extracorporeal Life Support Organization Registry data confirm that the number of pediatric patients being supported by extracorporeal membrane oxygenation (ECMO) is increasing. To minimize the potential neurologic effects of carotid artery ligation, the common femoral artery (CFA) is frequently being used for arterial cannulation. The cannula has the potential for obstructing flow to the lower limb, thus increasing ischemia and possible limb loss. We present a single institution's experience with CFA cannulation for venoarterial (VA) ECMO and ask whether any precannulation variables correlate with the development of significant limb ischemia. ⋯ Limb ischemia remains a significant problem, as more than half of our patients developed it. The true incidence may not be known as a 60% mortality in the no-ischemia group could mask subsequent ischemia. Although children are at risk for developing limb ischemia/loss, no variable was predictive of the development of significant limb ischemia in our series. Because of the inability to predict who will develop limb ischemia, early routine placement of a DPC at the time of cannulation may be warranted. However, DPCs do not completely resolve issues around tissue loss and morbidity. Prevention of limb ischemia/loss because of CFA cannulation for VA ECMO continues to be a problem that could benefit from new strategies.
