Office hysteroscopy: back to the future!

Hysteroscopy and anesthesia have come a long way in the last 150 years. While traditionally performed in the operating theater under general anesthesia, the alternative approach - so-called 'office' hysteroscopy - has gained popularity in recent years. Supporters of this modality cite the 'see and treat' capabilities, avoidance of anesthesia, more rapid turn-around time, and favorable economics as advantages. On the other hand, some question the success rate, capabilities, and patient comfort levels as potential drawbacks. In this article, we review the evidence behind all of these points as well as the requirements for setting up an office hysteroscopy service.

Optimizing the P300-based brain-computer interface: current status, limitations and future directions.

This paper summarizes the presentations and discussions at a workshop held during the Fourth International BCI Meeting charged with reviewing and evaluating the current state, limitations and future development of P300-based brain-computer interface (P300-BCI) systems. We reviewed such issues as potential users, recording methods, stimulus presentation paradigms, feature extraction and classification algorithms, and applications. A summary of the discussions and the panel's recommendations for each of these aspects are presented.
