Alpha-fetoprotein (AFP) is used as a tumor marker for hepatocellular carcinoma, hepatoblastoma and germ cell tumors. It may also be elevated in infants with some hepatobiliary disorders. The mechanism of AFP elevation in neonatal cholestasis is not known. We retrospectively evaluated serum AFP levels in 53 infants with neonatal cholestasis. Thirty patients (56.6%) had elevated AFP, and the ratio of patients with elevated AFP was significantly high in both the metabolic diseases and idiopathic neonatal hepatitis groups (p=0.021). Serum aspartate aminotransferase (AST) levels increased significantly in patients with elevated AFP (p=0.004). Steatosis was the distinctive histopathological finding of the patients with high AFP. The patients with steatosis had significantly higher standard deviation (SD) score of AFP than the patients without steatosis (p=0.001). We have shown AFP elevation in neonatal cholestasis due to metabolic disorders and idiopathic neonatal hepatitis and its association with steatosis and AST elevation.

An esophageal stricture is one of the complications that may develop during cancer treatment in children. Although more commonly associated with radiotherapy, recurrent mucositis has also been implicated. Presented herein is a case of a patient with acute lymphoblastic leukemia who suffered recurrent attacks of severe mucositis. Initial management of ensuing dysphagia included antifungal treatment for candida esophagitis. A subsequent upper endoscopy due to persistence of dysphagia revealed the presence of an esophageal stricture. Our aim in presenting this case is to emphasize the importance of considering a diagnosis of esophageal stricture in patients receiving anti-cancer treatment; early endoscopic intervention may be warranted in some patients.
