New trends in the management of hepatic Echinococcus granulosus.

The liver is the most commonly involved organ in the body by cystic echinococcosis (CE) secondary to infection with Echinococcus granulosus. In this article, the authors discuss the classification, recent advances in magnetic resonance (MR) imaging for the diagnosis of hepatic CE, and approaches for management of hepatic CE using five therapeutic options that include: antihelminthic chemotherapy, surgery, percutaneous treatment, endoscopic approach, and the "watch and wait" approach.

An overview of the pathogenesis and natural history of post-transplant T-cell lymphoma (corrected and republished article originally printed in Leukemia & Lymphoma, June 2007; 48(6): 1237 - 1241).

Post-transplantation lymphoproliferative disorders (PTLDs) are well recognized complications of solid organ transplantation. The vast majority of early PTLDs are B-cell non-Hodgkin lymphomas. PTLDs of T-cell origin occur much less frequently and account for only a minority of cases. T-cell PTLDs have been reported to occur primarily at extranodal sites, commonly affecting bone marrow or splenic tissues. The small bowel is an uncommon site of origin of these tumors with only seven cases of primary intestinal post-transplant T-cell lymphomas reported in the literature. We hereby report a new case of primary intestinal post-transplant T-cell lymphoma, arising 18 years following renal transplantation, along with a literature review of all published cases.

Brucella prostatic abscess: first case report.

Brucellosis is a multi-system disease that is endemic in many Mediterranean countries including Lebanon. However, human Brucella prostatic abscess was not reported in the English medical literature. We here describe the case of a young man who presented with fever and urinary symptoms, and who subsequently proved to have culture confirmed Brucella prostatic abscess. The culture of drained pus grew Brucella melitensis.

Biliary fascioliasis: case report and review of the literature.

Hepatobiliary parasitic diseases are rare in Lebanon. We recently encountered biliary fascioliasis in a Lebanese native. The clinical and laboratory findings were nonspecific. The biliary parasite (Fasciola hepatica) was identified by sonography and confirmed at ERCP that has retrieved the parasite from the common bile duct.
