3% and 80.9%, respectively. Adjusting the SUVmax ratio to 2.14, 16.7% (5/30) of ≥ T1b patients were identified without any false-positive cases. Multivariate analysis showed SUVmax ratio, Charlson comorbidity index, and esophagectomy were independent predictors for survival. SUVmax ratio (lesion/liver) is more accurate in predicting endoscopic resectability and mortality for EAC than other PET/CT parameters and appears promising as a useful adjunct to the current diagnostic

“Establishing a diagnosis of Wilson’s disease (WD) is often challenging in young, asymptomatic patients. The consensus on diagnostic criteria using clinical, biochemical, and genetic studies has previously been reviewed, and diagnostic algorithms have been proposed.1 In addition, a WD scoring system for the evaluation of patients was previously set forth and adopted at an international conference on WD.2 This scoring system has been subsequently validated in adult populations but not in pediatric ones.3-5 ATP7B, ATPase, Cu++ transporting, beta polypeptide; CDG, congenital disorder of glycosylation; KF, Kayser-Fleischer;

PCT, penicillamine challenge test; WD, Wilson’s disease. In this issue of Hepatology, Nicastro et al.6 evaluate the conventional diagnostic criteria for WD in a pediatric population. They compare a cohort of patients with known WD (n = 40) diagnosed by liver copper concentration or by the ATP7B genotype who were clinically asymptomatic except for elevated aminotransferases BMS-777607 supplier (34 of 40 patients) against a control population of patients with liver disease other than WD (n = 58). The evaluated diagnostic parameters include the presence of Kayser-Fleischer (KF) rings, serum copper, ceruloplasmin, 24-hour basal urinary copper excretion, 24-hour urinary copper excretion after a penicillamine challenge test (PCT), hepatic copper content, liver histology, ATP7B genotype, and WD scores2 calculated with two urinary copper measurements with a diagnostic cutoff of >40 μg/24

hours or >100 μg/24 hours. Let us examine these potential diagnostic variables independently and then together as a WD score. It has previously been shown that in a pediatric age group less than 10 years old, KF rings are more prevalent in symptomatic patients versus asymptomatic patients (75% and 12.5%, respectively).3 In agreement with other pediatric studies,7 eltoprazine in this study, KF rings were present in only 5% (2 of 40 patients), with the youngest with KF rings being 16 years old. From these observations, we can conclude that a slit lamp examination is likely not to be useful in most asymptomatic patients before puberty. However, because of the high specificity of this finding and the noninvasive nature of the testing, it should still be performed when possible. Lowering the diagnostic cutoff for basal urinary copper from 100 to 40 or 63.5 (1 μmol) μg/24 hours has been shown to be useful in pediatric patients.
