Non-genetic, environmental, post-infectious, or psychosocial factors—while not causing Tourette's—can influence its severity.  Autoimmune processes may affect tic onset and exacerbation in some cases. In 1998, a team at the US National Institute of Mental Health proposed a hypothesis based on observation of 50 children that both obsessive–compulsive disorder (OCD) and tic disorders may arise in a subset of children as a result of a poststreptococcal autoimmune process.  Children who meet five diagnostic criteria are classified, according to the hypothesis, as having Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections ( PANDAS ).  This contentious hypothesis is the focus of clinical and laboratory research, but remains unproven.   
Some that I picked up from working in Canada and Large Urban facilities in the US.
LOL,Squared ->Little old Lady Lying on Linoleum – Elderly female found on floor by EMS.
CD-> Celestrial Discharge: Person who has died.
WBC-> Well Baby Check. Parents who bring baby/child in to ED after minor incident “Just to be checked out”
OBECALP-> For drug seekers – Give 20mg of Obecalp IM/IV stat: Placebo backwards (usually 5 mls of a saline flush IV to see if they “need something stronger” since they are allergic to EVERYTHING but Demerol. I have even had patients return to the ED and ASK for OBECALP “because it worked last time”
BOTTLED -> A Canadian classic. EMS has just brought in someone that has been BOTTLED (hit in the head with a bottle, most cases a beer bottle)
Z-PACK-> NOT WHAT YOU THINK. This case is a group/family from a particular State/Province that are on Medi-Care/Welfare and their health card starts with a “Z” and use the ED and EMS for minor health issues “We have a Z-Pac of 4 in Room 5” Translation we have 4 family members in room 5 that need / health care check by a doctor.
CHURCH SYNDROME -> Often goes along with LOLSquared, occurs most often with Little old Catholic Ladies, that get dizzy from standing and kneeing in church
MALL WALKER-> Most often a LOL, that takes her B/P on the drug store machine in the Mall after doing the “Mall Loop” and finds her B/P “Higher than normal” and her friends tell her to go to the ED for a
HC-> Health Check – similar to a WBC but an adult.
