Currently, the Wallace Rule of Nines is the most widely used method to measure total body surface area (TBSA) in burned patients due to its practicality and speed in its application; however, it often provides inaccurate estimations in obese patients, affecting the fluid resuscitation process. ⋯ We found important differences in TBSA determination using the 3D Skanect-MeshmixerⓇ software compared with the Wallace Rule of Nines. Therefore, we generated a modified and optimized Wallace Rule of Nines estimations based on BMI. Future studies are needed to assess the safety and efficacy of this optimized table.

Case Reports
An Unusual Cause of Fever, Neck Pain, and Neck Stiffness: Acute Calcific Tendinitis of the Longus Colli Muscle.
Acute calcific tendinitis (ACT) of the longus colli muscle (LCM) is an inflammatory response due to deposition of calcium hydroxyapatite crystals. It is typically correlated with whiplash and overuse injuries. A common presentation of this inflammatory response is acute but progressive neck pain. It is a rare but important cause of neck pain that should be considered on a differential diagnosis when distinguishing between life-threatening conditions and non-life-threatening causes of neck pain. ⋯ A 51-year-old woman presented to the emergency department (ED) reporting a mild sore throat that progressed to acute neck pain and stiffness. She also reported fatigue, fever, myalgias, and nausea. In the ED, the patient was tachycardic, hypertensive, and mildly febrile with normal oxygen saturation. Examination revealed meningismus and was negative for lymphadenopathy, oropharyngeal findings, and neurologic deficits. Laboratory studies were significant for leukocytosis. Computed tomography (CT) neck was obtained and was notable for calcification of the superior left longus colli muscle with prevertebral and retropharyngeal space edema along the muscle body. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: ACT of the LCM is a benign, self-limited condition that can present with features overlapping emergent causes of acute neck pain. Correct diagnosis relies on characteristic radiographic findings on CT. Fortunately, patients may be discharged home with a short course of anti-inflammatories and corticosteroids with near-complete resolution of symptoms. Emergency physicians, therefore, can rule out life-threatening causes of neck pain, while also making a definitive diagnosis and initiating effective management for this pathology.

Case Reports
Oral and Transdermal Rivastigmine for the Treatment of Anticholinergic Delirium: A Case Report.
Anticholinergic toxicity is a common cause of delirium in emergency department patients. The standard antidotal treatment for anticholinergic toxicity is physostigmine. Physostigmine functions as a reversible acetylcholinesterase inhibitor that readily crosses the blood-brain barrier. Rivastigmine is another member of this class currently approved for the treatment of Alzheimer's disease and Parkinson's disease. Rivastigmine also crosses the blood-brain barrier and has been found to be effective in the management of anticholinergic toxicity in limited case reports. ⋯ A 61-year-old women presented to the emergency department via emergency medical services with altered mental status and a Glasgow Coma Scale score of 8 out of 15. She was found down near multiple medication bottles, including diphenhydramine and dicyclomine. Her physical examination was consistent with anticholinergic toxicity with mydriasis, obtundation, and warm flushed skin. In addition to standard resuscitation, she received two doses of rivastigmine 3 mg via nasogastric tube. After the second dose she was alert and oriented. She was admitted to the intensive care unit and had a rivastigmine patch applied. She was deemed back to her baseline 27 h after presentation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although the standard antidotal treatment for anticholinergic toxicity is physostigmine, there is a national shortage of this medication. In the absence of this standard antidote, it is reasonable for emergency physicians to use rivastigmine as an alternative treatment. This can be delivered orally or via nasogastric tube with dosing each hour until resolution of symptoms. Alternatively, in consultation with toxicology, it may be reasonable to use transdermal rivastigmine, as it provides consistent drug absorption for 24 h.

This study evaluated the predictive value of different laboratory indicators for the severity of acute cholangitis (AC) according to the 2018 Tokyo Guidelines. ⋯ PCT can be used as a reliable predictor of severe AC. CRP was most predictive of moderate AC, whereas PLR was most predictive of blood culture positivity.

Opioid overdose deaths in 2021 were the highest ever, driven by fentanyl and polysubstance use. ⋯ Most participants had UDS specimens containing multiple substances; a high proportion had fentanyl, stimulants, and buprenorphine. Regional differences were noted. Given the increased risk of death with fentanyl and polysubstance use, ED providers should be providing risk reduction counseling, treatment, and referral.
