An Inexpensive, Multimodal Simulation Model for Teaching Ultrasound Identification of Soft Tissue Pathology and Regional Anesthesia.

Ultrasound identification of soft tissue pathology is a useful skill for the emergency physician, but it requires practice and familiarity to be effective. Given its rising popularity in the Emergency Department, regional anesthesia is another essential skill that requires practice. Realistic models can help create procedural confidence and accuracy. Since entry-level professional-grade models can be cost-prohibitive, the development of simple and affordable models for teaching is valuable for emergency provider education, especially in resource-limited settings. Other inexpensive models have been produced and discussed in ultrasound; literature; however, no models have yet been designed for the replication of several different modalities in a single model. We developed and successfully tested a meat phantom model utilizing materials available at a local grocery store that can be quickly assembled in a short amount of time with minimal effort. This low-cost, easy-to-make phantom accurately replicates human tissue and pathology and is ideal for learners to practice several skill sets at once.

Mycobacterium marinum cellulitis: A fishy etiology.

Skin and soft tissue infections account for 2% of emergency department visits annually, though more unusual causative bacteria associated with saltwater exposure may result in morbidity. Mycobacterium marinum represents a rare but important cause of cellulitis, which if untreated or improperly managed, can progress to dactylitis or osteomyelitis. This unusual diagnosis is made more challenging due to the prolonged incubation period of approximately 21 days, temporally separating the inoculation from the disease. Patients will present with a nodular rash in a sporotrichoid pattern. While doxycycline is one antibiotic providing saltwater coverage, M. marinum has variable sensitivities to anti-mycobacterial antibiotics, and thus biopsy helps confirm the diagnosis as well as provide sensitivities for treatment. Emergency clinicians should inquire about environmental risk factors when caring for patients with cellulitis, especially with atypical skin presentations, and consider M. marinum as a rare but important cellulitis etiology.

Tattoo Associated Native Valve Infective Endocarditis.

Infective Endocarditis (IE) is an uncommon illness in the emergency department (ED) with significant associated morbidity. Patients with IE typically possess risk factors predisposing them to bacterial invasion. These risk factors include intravenous drug use, valvulopathies, valve replacement, poor oral hygiene, immunocompromised state, and recent invasive procedures. A rarer condition is tattoo-associated IE. Diagnosis of IE includes multiple blood cultures and echocardiography. Therapeutic interventions include prolonged intravenous antibiotics and potential surgery. Complications from IE can be severe, including organ injury from septic emboli, heart failure, valvular insufficiency, bacteremia, and fulminant septic shock. Prompt identification and treatment are necessary to reduce patient morbidity and mortality.

Small Bowel in Vagina: A Case for Pelvic Exams.

Vaginal cuff dehiscence with small bowel evisceration is a serious but uncommon postoperative complication of total laparoscopic hysterectomies. The severity of surgical site dehiscence can range from small, partial to full-thickness wound dehiscence, manifesting with acute abdominal pain, vaginal bleeding, or discharge, and is often precipitated by sexual intercourse. While imaging, including a pelvic ultrasound and computed tomography (CT), may help in undifferentiated acute abdominal pain, vaginal cuff dehiscence remains a clinical diagnosis found on physical exam. Because vaginal cuff dehiscence is a clinical diagnosis, sparse data exist regarding radiographic sensitivities and specificities in the identification of vaginal cuff dehiscence. Despite the increasing literature suggesting that pelvic exams are invasive with often limited utility, the authors argue that pelvic exams remain essential in identifying complications of hysterectomies. The authors present a case of a 40-year-old woman with acute abdominal pain found to have loops of small bowel in the vaginal vault, discovered only on physical exam after negative CT and ultrasound imaging.
