Second-hand exposure to aerosols containing fentanyl and other opiates during surgical procedures has been implicated as possibly contributing to maintenance of addiction among medical professionals, specifically anesthesiologists. This article outlines a pilot study that was conducted to verify a reported finding fentanyl in the air of operating suites. Environmental fentanyl air sampling and analysis methods were developed and evaluated for this study. ⋯ Samples were extracted and analyzed by high-performance liquid chromatography/tandem mass spectrometry using a capillary high-performance liquid chromatography coupled to a quadrupole time-of-flight mass spectrometer. The total air volume collected per surgery was 290 to 300 L at a rate of 1 LPM giving an limit of quantification for fentanyl of 57 pg/m(3) air (17 pg/filter). No fentanyl was detected in the air during cardiovascular surgical operations from either surgical suite.

We analyzed intentional exposures to prescription opioids (buprenorphine, fentanyl, hydrocodone, hydromorphone, morphine, methadone and Oxycodone) using the Research Abuse, Diversion and Addiction-Related Surveillance System (RADARS) Poison Center data over a 5 year period 2003-2007 to see if there were temporal trends in the abuse and misuse of prescription drugs associated with (1) weekends vs. weekdays and (2) during select holiday periods vs. non-holiday periods. Over the study period 25 of 120 holiday period days showed a decrease of at least 1 SD from the mean and 9 of 120 holiday period days showed an increase of at least 1 SD from the mean. Over the study period there were 144,653 intentional exposures. ⋯ In summary, the prevalence of abuse and misuse of prescription drugs was not impacted by day of the week or difference between weekday and weekend. The impact of 8 traditional holidays appeared to be associated with a minor decrease in abuse and misuse of prescription drugs. No temporally related increase in abuse and misuse of prescription drugs was noted and conversely a trend toward decreased abuse and misuse of prescription drugs was suggested.

Comparative Study
Favorable mortality profile of naltrexone implants for opiate addiction.
Several reports express concern at the mortality associated with the use of oral naltrexone for opiate dependency. Registry controlled follow-up of patients treated with naltrexone implant and buprenorphine was performed. In the study, 255 naltrexone implant patients were followed for a mean (+/- standard deviation) of 5.22 +/- 1.87 years and 2,518 buprenorphine patients were followed for a mean (+/- standard deviation) of 3.19 +/- 1.61 years, accruing 1,332.22 and 8,030.02 patient-years of follow-up, respectively. ⋯ Most sex, treatment group, and age comparisons significantly favored the naltrexone implant group. Mortality rates were shown to be comparable to, and intermediate between, published mortality rates of an age-standardized methadone treated cohort and the Australian population. These data suggest that the mortality rate from naltrexone implant is comparable to that of buprenorphine, methadone, and the Australian population.

A variety of surveys and studies are examined in an effort to better understand the scope of prescription drug diversion and to determine whether there are consistent patterns of diversion among various populations of prescription drug abusers. Data are drawn from the RADARS System, the National Survey of Drug Use and Health, the Delaware School Survey, and a series of quantitative and qualitative studies conducted in Miami, Florida. ⋯ In all of the studies examined, the use of the Internet as a source for prescription drugs is insignificant. Little is known about where drug dealers are obtaining their supplies, and as such, prescription drug diversion is a "black box" requiring concentrated, systematic study.

Methadone dosing has been an issue of controversy among clinicians for a long time. Few recent studies reported that doses above 100 mg daily seem promising in better control of illicit opiate use for some patients, but more research is needed to support that notion. A retrospective chart review for patients maintained on methadone at Atlanta Veterans Affairs Medical Center was conducted. ⋯ ASI scores for drugs did not show statistically significant improvement for the moderate dose group (p =.19) but showed statistically significant improvement for the high dose group (p =.0002) when the result of the first and last ASI scores among each group were compared. The ASI scores for family problems showed statistically significant improvement for the moderate dose group (p =.03). High doses of methadone greater than 100 mg daily may provide a better outcome for illicit opiate use among some patients who would not respond to moderate doses.
