Deep brain stimulation for essential tremor: a systematic review.

Deep brain stimulation (DBS) is a neurosurgical treatment, which has proven useful in treating Parkinson's disease. This systematic review assessed the safety and effectiveness of DBS for another movement disorder, essential tremor. All studies concerning the use of DBS in patients with essential tremor were identified through searching of electronic databases and hand searching of reference lists.

A review of natural orifice translumenal endoscopic surgery (NOTES) for intra-abdominal surgery: experimental models, techniques, and applicability to the clinical setting.

Objective: Evaluation of models, techniques, outcomes, pitfalls, and applicability to the clinical setting of natural orifice translumenal endoscopic surgery (NOTES) for performing intra-abdominal surgery through a systematic review of the literature.

Summary Background Data: NOTES has attracted much recent attention for its potential to allow traditional surgical procedures to be performed entirely through a natural orifice. Amid the excitement for potentially scar-free surgery and abolishment of dermal incision-related complications, the safety and efficacy of this new surgical technology must be evaluated.
