Xanthogranulomatous cholecystitis (XGC) is a rare form of chronic gallbladder inflammation that most commonly presents as acute cholecystitis and is often mistaken for carcinoma of the gallbladder. This case details the hospital course and follow-up of a 77-year-old male who developed suspected acute acalculous cholecystitis (AAC) resulting in severe sepsis after elective left total knee arthroplasty (TKA). Histopathological findings after elective cholecystectomy later revealed XGC as the underlying etiology., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, League et al.)

Congenital absence of the left pulmonary artery remains a rarely reported anomalous condition and is even less commonly seen in conjunction with a right-sided aortic arch. While most cases are identified during prenatal fetal ultrasonography and require early childhood intervention, some asymptomatic cases can go unrecognized until incidentally detected on chest imaging as an adult. This case details a 31-year-old male with a congenital absence of the left pulmonary artery and right-sided aortic arch with subsequent atretic and fibrotic lung, all found on imaging during admission for acute alcoholic hepatitis., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, League et al.)

Background: We aim to investigate factors that may contribute to failure of eradication of dysplastic Barrett's Esophagus among patients undergoing radiofrequency ablation treatment., Methods: A retrospective review of patients undergoing radiofrequency ablation for treatment of Barrett's Esophagus was performed. Data analyzed included patient demographics, medical history, length of Barrett's Esophagus, number of radiofrequency ablation sessions, and histopathology. Subsets of patients achieving complete eradication were compared with those not achieving complete eradication., Results: A total of 107 patients underwent radiofrequency ablation for Barrett's Esophagus, the majority white, overweight, and male. Before treatment, 63 patients had low-grade dysplasia, and 44 patients had high-grade dysplasia or carcinoma. Complete eradication was achieved in a majority of patients (57% for metaplasia, and 76.6% for dysplasia). Failure of eradication occurred in 15.7% of patients. The median number of radiofrequency ablation treatments in patients achieving complete eradication was 3 sessions, compared to 4 sessions for failure of eradication (p = 0.06). Barrett's esophagus length of more than 5 cm was predictive of failure of eradication (p < 0.001)., Conclusions: Radiofrequency ablation for dysplastic Barrett's Esophagus is a proven and effective treatment modality, associated with a high rate of complete eradication. Our rates of eradication from a center starting an ablation program are comparable to previously published studies. Length of Barrett's segment > 5 cm was found to be predictive of failure of eradication in patients undergoing radiofrequency ablation.

Expert groups recommend annual chest computed tomography for lung cancer screening (LCS) in high-risk patients. Lung cancer screening in primary care is a complex process that includes identification of the at-risk population, comorbidity assessment, and shared decision making. We identified three key processes required for high-quality screening implementation in our academic primary care practice: (1) systematic collection of lifetime cumulative smoking history to identify potentially eligible patients; (2) visit-based clinical reminders and order sets embedded in the electronic health record (EHR); and (3) tools to facilitate shared decision making and appropriate test ordering. We applied quality improvement techniques to address gaps in these processes. Over 12 months, we developed and implemented a nurse protocol for collecting complete smoking history and entering that data into discrete EHR fields. We obtained histories on over 50% of the clinic's more than 2,300 known current and former smokers, aged 55-80 years. We then built and pilot tested an automated visit-based reminder (VBR) system, driven by the discrete smoking history data. The VBR included an order set and template for documentation of shared decision making. Physicians interacted with the VBR in approximately 30% of opportunities for use. Further work is needed to better understand how to systematically provide appropriate LCS in primary care environments.

Objective: To determine the location of cortical activation during a visual illusion walking paradigm, a recently proposed treatment for spinal cord injury (SCI)-related neuropathic pain, in persons with SCI compared with able-bodied controls., Design: Pilot experimental functional magnetic resonance imaging (fMRI) trial., Setting: Outpatient rehabilitation clinic., Participants: Persons with paraplegia (n=3) and able-bodied participants (n=5) were included in this study., Interventions: Not applicable., Main Outcome Measure: Cortical activation as measured by the blood oxygenation level-dependent method of fMRI., Results: During visually illusory walking there was significant activation in the somatosensory cortex among those with SCI. In contrast, able-bodied participants showed little to no significant activation in this area, but they showed activation in the frontal and premotor areas., Conclusions: Treatment modalities for SCI-related neuropathic pain that are based on sensory input paradigms (eg, virtual walking, visual illusory walking) may work by targeting the somatosensory cortex, an area that has been previously found to functionally reorganize after SCI., (Copyright © 2015 American Congress of Rehabilitation Medicine.
