The Rottinger approach for total hip arthroplasty: technique and review of the literature.

The surgical approach utilized in total hip arthroplasty has been identified as a factor that may affect surgical outcomes. There have been many different approaches and modifications used since the procedure was popularized by Sir John Charnley. The popular approaches today can be grouped by their relationship to the trochanter (anterior or posterior), patient position, leg position for dislocation/femoral preparation, and treatment of the abductors and short external rotators.

Management of impulse control disorders in Parkinson's disease.

Impulse control disorders (ICDs) are a set of behaviors, including pathologic gambling, hypersexuality, compulsive shopping, compulsive eating, and punding, which are now recognized to occur in a subset of patients with Parkinson's disease (PD). Although the underlying pathophysiology of these behaviors is poorly understood, they appear to be associated with the use, and sometimes overuse, of dopaminergic agents prescribed for the treatment of the motor symptoms of PD. At present, there are limited data to support any particular therapeutic strategy.
