Pseudo-Romaña Sign Due to Botfly Infestation.

We report a patient who presented with unilateral periorbital edema after a short-term travel to an endemic area for Chagas disease and exposure to triatomine (reduviid) bugs. The diagnosis, however, was furuncular myiasis, not Chagas disease. This case emphasizes that there are multiple parasitic agents besides Trypanosoma cruzi that may be associated with clinical findings consistent with Romaña sign.

Liver transplantation for hepatocellular carcinoma: defining the impact of using extended criteria liver allografts.

BACKGROUND: This series compares outcomes of patients with hepatocellular carcinoma (HCC) listed for orthotopic liver transplantation (OLT) within and outside Milan criteria, and determines the impact of extended criteria liver allografts (ECD). METHODS: Records of patients listed for liver transplantation at a single center from 1998 to 2007 were reviewed retrospectively. RESULTS: Ninety-seven HCC patients were listed for OLT, 77 underwent transplantation; 47 received ECDs and 30 standard organs. ECDs were more frequently allocated to outside Milan recipients. Wait time for OLT was shorter for outside Milan patients (4 vs. 7 months P=0.04) but hazard rate of dropout was higher (26%, 46%, and 73% at 6,12, and 24 months compared with 2%, 14%, and 60% P<0.01). Tumor size more than 3 cm (P=0.02) and model for end-stage liver disease score at listing more than 11 (P=0.04) were independent predictors of dropout. Hazard rate of OLT was similar within and outside Milan (61%, 80%, and 90% at 6, 12, and 24 months vs. 60%, 70%, and 86% P=0.38). Post-OLT survival at 1 year and 4 years were 88% and 63% within Milan compared with 79% and 62% among Milan out recipients (P=0.95). No significant post-OLT survival predictor was found. CONCLUSION: The use of ECD organs provided patients with HCCs outside Milan criteria access to liver transplant at a rate comparable to patients within Milan and model for end-stage liver disease HCC priority. Similar patient survival post-OLT can be achieved using standard or ECD organs. The higher risk of drop out in patients outside Milan, and even within Milan, with tumors more than 3 cm justifies the use of ECD organs for timely transplantation.

Surgical dilemma: liver resection or liver transplantation for hepatocellular carcinoma and cirrhosis. Intention-to-treat analysis in patients within and outwith Milan criteria.

BACKGROUND: The optimal role of surgery in the management of hepatocellular carcinoma (HCC) is in continuous evolution. OBJECTIVE: The objective of this study was to analyse survival rates after liver resection (LR) and orthotopic liver transplantation (OLT) for HCC within and outwith Milan criteria in an intention-to-treat analysis. METHODS: During 1997-2007, 179 patients with cirrhosis and HCC either underwent LR (n= 60) or were listed for OLT (n= 119). Patients with incidental HCC after OLT, preoperative macrovascular invasion before LR, non-cirrhosis and Child-Pugh class C cirrhosis prior to OLT were eliminated, leaving 51 patients primarily treated with LR and 106 patients listed for primary OLT (84 of whom were transplanted) to be included in this analysis. A total of 66 patients fell outwith Milan criteria (26 LR, 40 OLT) and 91 continued to meet Milan criteria (25 LR, 66 OLT). RESULTS: The median length of follow-up was 26 months. The mean waiting time for OLT was 7 months. During that time, 21 patients were removed from the waiting list as a result of tumour progression. Probabilities of dropout were 2% and 13% at 6 and 12 months, respectively, for patients within Milan criteria, and 34% and 57% at 6 and 12 months, respectively, for patients outwith Milan criteria (P < 0.01). Tumour size >3 cm was found to be the independent factor associated with dropout (hazard ratio [HR] 6.0). Postoperative survival was slightly higher after OLT, but this was not statistically significant (64% for OLT vs. 57% for LR). Overall survival from time of listing for OLT or LR did not differ between the two groups (P= 0.9); for patients within Milan criteria, 1- and 4-year survival rates after LR were 88% and 61%, respectively, compared with 92% and 62%, respectively, after OLT (P= 0.54). For patients outwith Milan criteria, 1- and 4-year survival rates after LR were 69% and 54%, respectively, compared with 65% and 40%, respectively, after OLT (P= 0.42). Tumour size >3 cm was again found to be an independent factor for poor outcome (HR 2.4) in the intention-to-treat analysis. CONCLUSIONS: Survival rates for patients with HCC are similar in LR and OLT. Liver resection can potentially decrease the dropout rate and serve as a bridge for future salvage LT, particularly in patients with tumours >3 cm.
