For every course of radiotherapy treatment, the potential benefit has to be weighed against the risk of normal tissue damage. Radiation-induced proctitis during and after radical radiotherapy for prostate cancer can be decreased by reducing both the size of the target volume and the margins required around this volume. In the future, target volumes could be reduced by both CT/MRI co-registratio...
BACKGROUND Therapeutic biliary procedures disrupt the function of the sphincter of Oddi. Patients are potential "bile refluxers". The aim of this study was to assess how these procedures affect the histology-based bile reflux index (BRI), which can be used to reflect duodenogastric reflux (DGR). METHODS Gastric antrum and corpus biopsies were collected from 131 subjects (56 men, 75 women; mea...

Factors contributing to this include the narrow therapeutic index, patient-specific target range, and the need for regular INR monitoring.

The US Food and Drug Administration (FDA) has recently suggested that the bioequivalence (BE) for products of drugs with narrow therapeutic indices (NTI) be assessed by the approach of reference-scaled average BE (SABE). Subsequently, in December, 2012, the FDA issued draft guidances for the comparison of products of warfarin sodium and of tacrolimus. The guidances expect that 4-period studies ...
Considerable economic and health-related costs are associated with the life-long maintenance immunosuppressive therapy required to prevent transplant rejection. Generic medications have the potential of providing equivalent therapeutic efficacy at a lower economic cost. In 2001, the American Society of Transplantation invited experts to review the data and issues associated with the approval an...
