Effect of prior hepatitis B virus exposure on long-term risk of liver-related events after liver transplantation.

Objective: To characterize the risk of liver-related events and death in hepatitis B virus (HBV)-exposed liver transplantation (LT) recipients.

Methods: Retrospective review was performed in all adults who underwent LT between January 1995 through December 2010 at the Johns Hopkins Hospital. Recipients with graft failure or death within 14 d of LT or missing HBV status were excluded, leaving 575 individuals for analysis.

Quantitative visualization and detection of skin cancer using dynamic thermal imaging.

In 2010 approximately 68,720 melanomas will be diagnosed in the US alone, with around 8,650 resulting in death. To date, the only effective treatment for melanoma remains surgical excision, therefore, the key to extended survival is early detection. Considering the large numbers of patients diagnosed every year and the limitations in accessing specialized care quickly, the development of objective in vivo diagnostic instruments to aid the diagnosis is essential.
