Iatrogenic immunodeficiency-associated lymphoproliferative disorder presenting as small bowel perforation.

A woman in her late 50s on mycophenolate for limited systemic sclerosis presented with abdominal pain. Vital signs and investigative evaluations were normal. Cross-sectional imaging identified gastric and small bowel wall thickening, free fluid, and pneumoperitoneum. In the operating room, a small bowel perforation was found and resected. Postoperatively, immunosuppression was held and she completed a course of amoxicillin/clavulanate. She discharged home and re-presented on postoperative day 8 with seizures and was found to have a frontal brain mass which was biopsied. Pathology from both the resected bowel and brain biopsy demonstrated Epstein-Barr virus-positive B-cell lymphoproliferative disorder with polymorphic B-cell features. The patient's immunosuppression was discontinued, and she was enrolled in a clinical trial for chemotherapy. Lymphoproliferative disorder can present years after immunosuppression initiation with either spontaneous perforation or solid tumour. Pathological assessment determines treatment options. Heightened concern for atypical clinical presentations in immunosuppressed patients is always warranted.

Simple signage and targeted education can lead to process improvement in acute appendicitis care.

INTRODUCTION: An institution-wide protocol for uncomplicated acute appendicitis was created to improve compliance with best practices between the emergency department (ED), radiology and surgery. Awareness of the protocol was spread with the publication of a smartphone application and communication to clinical leadership. On interim review of quality metrics, poor protocol adherence in diagnostic imaging and antimicrobial stewardship was observed. The authors hypothesised that two further simple interventions would result in more efficient radiographic diagnosis and antimicrobial administration. MATERIALS AND METHODS: Surgery residents received targeted in-person education on the appropriate antibiotic choices and diagnostic imaging in the protocol. Signs were placed in the emergency and radiology work areas, immediately adjacent to provider workstations highlighting the preferred imaging for patients with suspected appendicitis and the preferred antibiotic choices for those with proven appendicitis. Protocol adherence was compared before and after each intervention. RESULTS: Targeted education was associated with improved antibiotic stewardship within the surgical department from 30% to 91% protocol adherence before/after intervention (p<0.005). Visible signs in the ED were associated with expedited antimicrobial administration from 50% to 90% of patients receiving antibiotics in the ED prior to being brought to the operating room before/after intervention (p<0.005). Diagnostic imaging after the placement of signs showed improved protocol adherence from 35% to 75% (p<0.005). CONCLUSION: This study demonstrates that smartphone-based applications and communication among clinical leadership achieved suboptimal adherence to an institutional protocol. Targeted in-person education reinforcement and visible signage immediately adjacent to provider workstations were associated with significantly increased adherence. This type of initiative can be used in other aspects of acute care general surgery to further improve quality of care and hospital efficiency.

Grilling pains: case series of four patients needing operative intervention after accidental ingestion of a wire bristle.

Accidental ingestion of a grill brush wire bristle is a rare event. Retrieval rarely requires surgical intervention as the wire typically causes symptoms above the gastro-oesophageal junction and can frequently be removed endoscopically. There are few reported cases of gastrointestinal injury due to ingestion of wire bristles lodging past the gastro-oesophageal junction in adults. We present four cases of wire brush bristle ingestion that required operative intervention. Our case series illustrates how the commonly used wire grill brush may cause a serious injury. This diagnosis should be considered in patients who present with abdominal pain, non-specific symptoms and normal labs, with liner radio-opaque imaging findings and a history of grill use. Education as to the dangers of grill wire brushes to clean grills should be provided commercially.

Vital Conversations: An Interactive Conflict Resolution Training Session for Fourth-Year Medical Students.

Introduction: The AAMC has recognized the importance of effective teamwork and collaboration. One core Entrustable Professional Activity emphasizes creating a climate of mutual respect and trust and prioritizing team needs over personal needs, which leads to safe, timely, effective, efficient, and equitable patient care. Relationship conflicts, specifically, are associated with decreased productivity, complex information processing, and work satisfaction. Given the prevalence of conflict and its impact on health care workers, the lack of conflict resolution curricula in undergraduate medical education is surprising. We developed a curriculum formally introducing these skills and allowing practice in a simulated environment before students entered residency. Methods: Fourth-year medical students completed a conflict resolution exercise in a mandatory transition-to-residency course. Students completed online prework including reflection on teamwork and information on conflict resolution styles, participated in a simulated conflict with a standardized patient acting as a nurse, and afterward completed a self-evaluation with video review by the students' assigned coach and feedback on the session. Results: We collected complete responses from 108 students. We evaluated the curriculum for feasibility and acceptability by faculty and students. Most students agreed with faculty on their entrustment and milestone levels. Students found that the session prompted self-reflection and was a good review of conflict resolution. The standardized patient and faculty feedback was found to be the most useful by the students. Discussion: We successfully implemented a simulated but realistic conflict resolution exercise. Students found the exercise helpful in their preparation for residency.

New modalities of neurostimulation: high frequency and dorsal root ganglion.

PURPOSE OF REVIEW: Neurostimulation is a well tolerated, cost-efficient, and effective method to treat chronic pain. Although spinal cord stimulation (SCS) has been shown to help patients, newer modalities such as burst, kilohertz-frequency, and dorsal root ganglion stimulation may provide greater pain relief, fewer paresthesias, and better outcomes. RECENT FINDINGS: Burst stimulation, programed as five-impulse burst at a frequency of 500 Hz, delivers more charge per second than conventional stimulation. Trials of burst stimulation have shown superior pain relief, decreased paresthesias, and patient preference compared with conventional SCS. Kilohertz-frequency SCS uses low-amplitude, high-frequency (10 kHz), and short-duration pulses. The SENZA trial showed superiority in both back and leg pain with greater pain relief as well as decreased opioid use. Dorsal root ganglion stimulation stimulates the ganglion cells allowing for precise targeting of pain regions. Multiple studies, including the ACCURATE trial, have shown superior pain relief in multiple conditions. SUMMARY: Improvements in pain control and patient satisfaction suggest that these new stimulation patterns will greatly increase the utility of neurostimulation; however, clinical trials with broader patient populations have to be done to support more extensive use of these therapies.
