Cancer Vaccines: Past, Present, and Future.

Cancer is a common and potentially deadly disease. Some of the cancers may be difficult to treat by conventional means such as surgery, radiation, and chemotherapy, but may be controlled by the stimulation of the immune response of the body with the help of cancer vaccines. The use of vaccines for preventing infections by oncogenic viruses such as hepatitis B virus and human papilloma virus has been extremely successful in reducing the incidence of cancers resulting from these infections.

Recovery of liver perfusion after focal outflow obstruction and liver resection.

Background: Live liver donation requires extended liver resection in the donor with transection of the middle hepatic vein. This leads to focal outflow obstruction in the remnant liver or the partial graft. This study was designed to characterize the pathophysiological correlate of focal outflow obstruction in a small-for-size liver and its course of recovery in a rat model.

Septic shock caused by Sphingomonas paucimobilis bacteremia in a patient with hematopoietic stem cell transplantation.

Sphingomonas paucimobilis is an aerobic gram-negative bacillus that causes a variety of infections in healthy as well as in immunocompromised individuals. The organism is usually susceptible to tetracycline, chloramphenicol, aminoglycosides, trimethoprim-sulfamethoxazole, and carbapenems. However, resistance to penicillins and the first-generation cephalosporins is commonly encountered.
