Prolonged venom-induced consumptive coagulopathy following Mangshan pit viper (Protobothrops mangshanensis) envenomation despite Hemato Polyvalent antivenom administration.

This case report summarizes an envenomation by the Mangshan pit viper (Protobothrops mangshanensis), a rare, endangered, venomous snake endemic to Mount Mang of China, and the first reported use of Hemato Polyvalent antivenom (HPAV) for this species. The snakebite occurred in a United States zoo to a 46-year-old male zookeeper. He presented via emergency medical services to a tertiary center after sustaining a single P. mangshanensis bite to the abdomen and was transported with antivenom from the zoo. Within 2 hours of envenomation, he developed oozing of sanguineous fluid and ecchymosis at the puncture site, and about 4 hours post-bite, was treated with HPAV. His coagulation profile fluctuated with the following pertinent peak/nadir laboratory values and corresponding hospital day (HD): undetectable fibrinogen levels, d-dimer 8.89 mg/L and 7.43 mg/L, and INR 2.97 and 1.46 on HD zero and three, respectively. Other peak/nadir values included hemoglobin 9.7 g/dL and creatinine phosphokinase 2410 U/L on HD four and platelets 81 × 109/L on HD seven. The patient received a total of 30 vials of HPAV over 5 days and 1 unit of cryoprecipitate on HD six. Upon discharge on HD eight, laboratory studies were normalizing, except for platelets, and edema stabilized. This case describes an acute, recurrent, and prolonged venom-induced consumptive coagulopathy despite prompt administration and repeated doses of HPAV.

The Erector Spinae Plane Block as Novel Therapy for Renal Colic: A Case Series.

We present a 10-patient case series supporting the use of the erector spinae plane block (ESPB) as a novel approach for the treatment of acute pain from renal colic. An in-plane needle approach was used with either transverse or longitudinal orientation of the ultrasound probe on the affected side, in either seated or prone patient position. These cases showed significant improvement in patient reported pain; suggesting that the ESPB can be used safely and effectively for either primary or adjunctive treatment of acute pain due to renal colic in the emergency department.

Peer-Developed Modules on Basic Biostatistics and Evidence-Based Medicine Principles for Undergraduate Medical Education.

Introduction: Evidence-based medicine (EBM) is pivotal in shaping patient care, yet it is challenging to incorporate into undergraduate medical education (UME) due to a lack of dedicated resources within the preclinical curriculum. To address this challenge, we used a peer-led approach to explain difficult concepts through language that students can understand at their shared level of understanding. Methods: Four second-year medical students trained in EBM over 18 months by facilitating monthly journal clubs, ultimately leading to their involvement as peer-instructors. With input from a faculty expert, peer-instructors designed integrative PowerPoint modules and interactive problem sets on basic biostatistics and EBM principles. Assessment included formative quizzes with multiple attempts to achieve at least 80% to demonstrate mastery of core learning objectives. Afterwards, students were invited to provide feedback using a 5-point Likert scale survey. Results: Of second-year students who participated, all 151 demonstrated 80% competency on each quiz. Eighty-seven (58%) students completed the survey on which, 77% agreed/strongly agreed that their level of understanding of EBM improved after the peer-led sessions, 76% agreed/strongly agreed that the sessions were more conducive to learning compared to traditional lectures, and 94% agreed/strongly agreed that the material covered was relevant to the USMLE Step 1. Discussion: This peer-led approach has been rated as effective by learners, improving their ability to critically appraise and apply clinical evidence. To promote integration of EBM into UME, we have prepared modules, problem sets, quizzes, and an outline of the problem-solving sessions for universal adoption.
