    Abstract pLT is a highly standardized therapy for children with end-stage liver disease and liver-based metabolic diseases. However, NCs after transplantation occur and especially younger children are considered as more vulnerable and susceptible to NCs. Up to now, detailed data particularly for the very young age group do not exist. We therefore retrospectively studied NCs in children after pLT under age of 24 months. Forty children aged between 19 days and 22 months were evaluated according to type of NC and potential risk factors. NCs occurred in 8/40 patients (20%). All experienced new-onset seizures and in 1/6 surviving patients, seizures evolved into epilepsy. Other NCs were intracerebral abscess (1/8 patients) and subdural hemorrhage (1/8 patients). The overall 3-year mortality rate was 10% (4/40 patients). Significant risk factors for NCs and therefore seizures were HAT (P = 0.020), total surgery time (P = 0.009), retransplantation (P < 0.001), period of catecholamine therapy (P = 0.024), period of mechanical ventilation (P = 0.014), and period of sedation (P = 0.010). Our study is the first to provide detailed information on NCs after pLT in children under 24 months of age. The incidence of NCs in this particular group of very young patients was not increased compared to previously published data of children of all ages. Main NC was new-onset seizure. In the surviving infants, prognosis of seizure was excellent and the risk of developing epilepsy was low. Even more, the occurrence of NCs did not significantly affect mortality or survival in this particular age group.

    Abstract Background: Using tissue microarrays, we investigated whether methylthioadenosine phosphorylase (MTAP) protein expression is associated with clinicopathologic variables in benign and malignant melanocytic skin tumors.
    Observations: Cytoplasmic MTAP expression was detected in 227 (72.1%) of 315 informative cases. Expression was significantly reduced in primary malignant melanomas and in melanoma metastases compared with benign nevi (P<.001 for both). No difference was noted in MTAP expression between primary malignant melanomas and melanoma metastases. In primary malignant melanomas, a Ki67-labeling index less than 5% was associated with MTAP expression (P = .04), suggesting that loss of MTAP expression is associated with proliferation. No other variables had significant associations with MTAP expression. Lymph node metastases demonstrated significantly higher MTAP expression compared with skin metastases (P = .01). In the overall cohort, MTAP expression was not associated with prognosis. Among 26 patients with MTAP-positive melanomas and tumor recurrence, 18 patients who received interferon therapy had a significant benefit compared with 8 patients who did not receive interferon therapy (P = .009). This was not seen in the patients with MTAP-negative tumors. Conclusion Methylthioadenosine phosphorylase protein expression may be a predictive marker of interferon therapy resistance in patients with melanoma and disease progression.
