Detective Goren notes the theft of a woman's ring from a box labelled "Suzanne Belperron". Belperron (1900-1983) was a real-life Parisian jewelry designer, still renowned today for her distinctively individual style. Knowingly stealing such a ring merely to reset the jewels into a different shape would indicate extraordinary arrogance and disregard for its unique value.
The episode title is an acronym for "Dispense As Written" - an instance of shorthand communication from an M.D. to a pharmacist.
Detective Goren says that Doctor Lindgard used to be addicted to a synthetic opioid called Pethidine. Pethidine is one of the brand names for the synthetic opioid meperidine, which is better known in the United States by the brand name Demerol, it has about one third the potency of morphine. Meperidine was first synthesized by German chemists in 1939, its was approved for use in the United States in the 1950's. By the 1960's it was the most prescribed opioid in ER's for acute pain, but by the 1980's it was discovered that the drug also had a lot of side effects and interactions, more so than most other opioids. It was originally thought to be safer, less addictive and more effective than morphine but a study done by a university showed that it had the same addiction potential as morphine and interacted with a number of medications that morphine does not interact with, plus it was also found that meperidine has a toxic metabolite that can cause psychological issues in long term users. Meperidine started to fall out of use in the 1990's with the advent of more effective and stronger opioids that had fewer side effects and interactions, such as hydromorphone (Dilaudid) and fentanyl. By 2003 it was removed from the World Health Organization's list of most effective medications and is no longer used in the United States.
Kevin Tighe, who played Dr. Lindgard, previously starred as paramedic Roy DeSoto in the TV series "Emergency" which ran from 1972-79.
