RESUMO
We study the implications of interpreting the recent muon g(mu) -- 2 deviation from the standard model prediction as evidence for virtual superpartners, with very general calculations that include effects of phases and are consistent with all relevant constraints. Assuming that the central value is confirmed with smaller errors, there are upper limits on masses: at 1.5 sigma, at least one superpartner mass is below about 450 GeV (550 GeV) for tan beta = 35 (50) and may be produced at the Fermilab Tevatron in the upcoming run.
RESUMO
Anesthetists and other providers are seeing an increased demand for sedation or anesthesia for challenging patients undergoing diagnostic procedures. Regardless of the specialty of the provider, proper attention must be paid to patient evaluation, monitoring, and drug dosage. The present review summarizes recommendations regarding sedation, as well as recent literature on sedation and anesthesia for endoscopy, radiology, pediatric oncology procedures, and pediatric electroencephalography.

Recent developments in pharmacology have offered new and broader options to the anesthesiologist caring for pediatric patients. Many new drugs do not have specific indications for use in the pediatric population, but clinical studies have examined the utility and cost-effectiveness of some of these agents. Information is presented on drugs used for premedication, induction, and maintenance of anesthesia. The clinical pharmacology of several new nondepolarizing muscle relaxants, and the recent controversy with regard to the use of succinylcholine also are presented. New drugs used in topical and regional anesthesia as well as options for anti-emetic therapy are discussed.

Most surgical and anesthesia personnel assume that certain factors lead to increased preoperative anxiety, yet the predictability of preoperative anxiety has not been extensively studied. We hypothesized that surgical and anesthesia personnel could be more effective in reducing preoperative anxiety if potential predictors of presurgical anxiety were identified. A sample of 523 patients awaiting elective surgery completed an anxiety scale, had their blood pressure and pulse measured, and had 14 different characteristics recorded. These characteristics included demographics, possibility of cancer, presence of support person, previous surgical experience, and extent of surgery. Female patients were more anxious than male patients, and individuals accompanied by a support person were more anxious than those not accompanied. However, all other factors were noncontributory to anxiety. It appears that patient anxiety does not reflect the assumptions of surgical and anesthesia personnel. This suggests that preoperative anxiety may reflect a patient's personality and coping style more than medical data.
