Podcast # 473: Direct to Consumer Antibiotics
Author: Sam Killian, MD Educational Pearls: A recent study in Pediatrics compared the rates of antibiotic prescriptions for acute respiratory infections (ARIs) between direct to consumer (DTC) telemedicine, urgent care, and primary care providers Among the nearly 530,000 visits studied, the rate of antibiotic prescription was 52%, 42% and 31% for telemedicine, urgent care, and primary care providers, respectively Nearly 4/10 antibiotic prescriptions from telemedicine visits were not indicated based on antibiotics guideline recommendations References Ray KN, Shi Z, Gidengil CA, Poon SJ, Uscher-Pines L, Mehrotra A.

Podcast # 472: SMART Crystalloids
Author: Gretchen Hinson, MD Educational Pearls: In most healthcare settings, normal saline (NS) has become ubiquitous as an intravenous fluid despite some potential drawbacks Compared to normal saline, a balanced crystalloid (either lactated Ringer’s or Plasma-Lyte) was associated with a lower composite endpoint of mortality, renal replacement therapy, and renal injury in SMART (Isotonic Solutions and Major Adverse Renal Events Trial) Balanced crystalloids such as lactate Ringer’s may be preferable in more critically ill populations References Yau YW, Kuan WS.

Podcast # 471: Cyclic Vomiting
Author: Don Stader, MD Educational Pearls: Cyclic vomiting syndrome (CVS) is different than cannabis hyperemesis syndrome (CHS). It is important to differentiate the two. CHS is thought to be caused by activation of THC receptors in the gut CVS is associated with migraines and therefore responds to similar medications Olanzapine (Zyprexa) is an alternative to haloperidol (Haldol) Amitriptyline, as well as anti-epileptics can be used to prevent CVS Opioids worsen CVS References Lapoint J, Meyer S, Yu CK, Koenig KL, Lev R, Thihalolipavan S, Staats K, Kahn CA.Cannabinoid Hyperemesis Syndrome: Public Health Implications and a Novel Model Treatment Guideline.

Author: Jared Scott, MD Educational Pearls: Ondansetron (Zofran) is one of the latest drugs that has had concerns raised about side effects, particularly in pregnancy 2018 study probed two birth defect databases to assess increases in 51 major birth defects with increased exposure to ondansetron Only two of the 51 had even a modest increase, which is unclear in causation (cleft palate and renal agenesis) When administering ondansetron (or any drug) to pregnant women, be able to discuss any potential risks for an informed decision by the patient Editor's note: in this study, adjusted odds ratios for risk of birth defects from exposure to ondansetron were: cleft palate 1.6 (95% CI 1.1-2.3) and renal agenesis 1.8 (95% CI 1.1-3.0) References Parker SE, Van Bennekom C, Anderka M, Mitchell AA.

Educational Pearls: Tiflitis refers to the presence of enterocolitis in the setting of neutropenia - also known as neutropenic enterocolitis Commonly a result of chemotherapy for hematologic malignancies. The infection is usually polymicrobial/fungal and can lead to septic shock Usually presents with fever, abdominal pain, with associated GI complaints Workup includes CBC for the ANC (usually <500), and a CT abdomen (look for bowel thickening) Treatment typically with broad-spectrum antibiotics with or without anti-fungal agents Mortality can be as high as 50% References Cloutier RL.

Podcast # 465: As easy and 1, 2, 10 - Capillary Refill and Sepsis
Author: Ryan Circh, MD Educational Pearls: The 2019 ANDROMEDA-SHOCK trial compared using serum lactates to capillary refill assessment in septic shock patients to guide resuscitation Capillary refill time was standardized (this is not straightforward): A glass microscope slide was pressed on the ventral side of the right index finger Pressure was increased until the skin was blanched This pressure was sustained for another 10 seconds After pressure was removed, the time to return to normal skin color was timed Greater than three seconds was considered abnormal. No difference between the two groups for mortality at 28-days Editor’s note: lactates have become so ingrained in our practice it will be tough to change habits but this is an excellent quiver for those of us that hate the over reliance on this lab value alone, despite some of the limitations of the study.

Author: Aaron Lessen, MD Educational Pearls: A problem of take-home-naloxone is the administration of it by an able-bodied bystander Australian study looked at consecutive opioid overdose deaths in a single year to identify characteristics of overdose and potential for bystander administered naloxone Of the 235 fatal heroin overdoses reviewed, 83% were alone with only 17% (38 cases) having another person present Half of those in the presence of others had a bystander that was not impaired Take-home-naloxone needs a competent person to administer it.

Author: Gretchen Hinson, MD Educational Pearls: Breath stacking occurs when a patient is unable to expire fully before another inspiration In intubated/ventilated patients, this is because adequate time has not passed before exhalation Asthmatics are susceptible due to the prolonged expiratory phase Complications can include reduction in cardiac preload and cardiovascular collapse Pursed-lip breathing can help in the spontaneously breathing patient Intubation may be required when patients present with status asthmaticus and breath stacking References Phipps P, Garrard CS.

Podcast # 451: NSAIDs
Author: Don Stader, MD Educational Pearls: Non-steroidal anti-inflammatory drugs (NSAIDs) are effective pain relievers but come with important side effects NSAIDs inhibit COX-1 and/or COX-2, which decreases the production of prostaglandins, which reduce pain and inflammation Side effects of NSAIDS include increased rates myocardial infarction, stroke, and gastrointestinal bleeding, CVA Effective pain reliever doses of many NSAIDs are lower than typically prescribed (i.e. ibuprofen 400 mg is as effective as 800 mg but with less risk of side effects) Topical NSAIDs can be an alternative to reduce systemic effects Selective Cox-2 inhibitors have less GI side effects Editor note: What is ALTO? It’s alternative to opioids and consists of multi-modal pain control to reduce exposure to opioids. Check out more here and here.

Podcast # 450: Probiotics in Gastroenteritis
Author: Sam Killian, MD Educational Pearls: Viral gastroenteritis alters the gut microbiome and it is theorized that probiotics may help reduce the duration and severity of the disease. Double-blind randomized controlled trial involving almost 900 children with viral gastroenteritis compared 5 days of probiotics to a control group. There was no difference in the rates of severe gastroenteritis between the two groups Probiotics are likely unhelpful for kid with viral gastroenteritis References: Freedman SB, Williamson-Urquhart S, Farion KJ, Gouin S, Willan AR, Poonai N, Hurley K, Sherman PM, Finkelstein Y, Lee BE, Pang XL, Chui L, Schnadower D, Xie J, Gorelick M, Schuh S; PERC PROGUT Trial Group..

Podcast #449: Banana Bags
Author: Dylan Luyten, MD Educational Pearls: A “banana bag” is a bag of IV fluid that contains various vitamins and minerals including folate and thiamine IV fluids do not alter intoxicated patients recovery in the emergency department Folate deficiency is rare in the intoxicated patient Some intoxicated patients may be thiamine deficient, and those that would benefit the most need significantly more daily thiamine supplementation than provided in a banana bag References: Perez SR, Keijzers G, Steele M, Byrnes J, Scuffham PA.

Podcast #447: IV Tylenol
Author: Dylan Luyten, MD Educational Pearls: Recent randomized controlled trial compared intravenous to oral acetaminophen in emergency department patients There was no difference in pain relief between the groups While the actual acquisition cost of these drugs are not significant, the cost multipliers that are passed onto patients lead to real dollars With the significant cost of IV acetaminophen, it may not be the best choice given the lack of superiority to other formulations References: Furyk J, Levas D, Close B, Laspina K, Fitzpatrick M, Robinson K, Vangaveti VN, Ray R.
