Postoperative Delirium Screening Characteristics in Pediatric Intestinal, Liver, and Renal Transplant Recipients: Single-Center Retrospective Cohort Study.

OBJECTIVES: To describe and compare the results of delirium screening in the immediate post-transplant PICU admission for pediatric intestinal, liver, and renal transplant recipients. We also examined associations with known and suspected risk factors for pediatric delirium (PD). DESIGN: Retrospective analysis of a single-center cohort, 2016-2022. SETTING: Twenty-four-bed PICU in a high-volume transplant center. PATIENTS: All intestinal, liver, and renal transplant recipients under 23 years old admitted between July 2016 and August 2022. MEASUREMENTS AND MAIN RESULTS: We identified 211 pediatric transplant recipients: intestinal (n = 36), liver (n = 78), and renal (n = 97). Results of the Cornell Assessment for PD during the immediate post-transplant PICU admission were reviewed and patients were categorized into screen positive, screen negative, and unscreened. Corresponding data on known and suspected risk factors for PD were also collected. Data on delirium subtypes were not collected. Screens were available for 156 of 211 patients (74%) who were included in the final analysis. The prevalence of a positive screen by transplant category was: intestine 80% (24/30), liver 75% (47/63), and renal 14% (9/63). A positive screen was associated with younger age, greater duration of mechanical ventilation, and greater PICU length of stay (LOS) in bivariate analysis. In multivariable analysis, age and PICU LOS remained strongly correlated with a positive screen (p < 0.05). Deep sedation and agitation as categorized by the State Behavioral Scale was associated with a positive screen, as was significant iatrogenic withdrawal symptoms (p < 0.05). Most patients screened positive by post-transplant days 2 and 3 (58/80 [72%] and 64/80 [80%], respectively). CONCLUSIONS: In our 2016 to 2022 experience, we found a high prevalence of positive PD screens in pediatric intestinal and liver transplant recipients in the immediate post-transplant PICU admission. A positive screen was associated with younger age and greater PICU LOS.

Analysis of Student Reflections on "What Matters Most" to Palliative Care Patients: A Narrative Medicine Exercise.

Background: Effective communication with ill patients requires practice, yet, the traditional history overlooks patients' personal stories. This information is vital to determining goals of care and facilitates partnership by building trust. Objective: We implemented a narrative medicine exercise for students during their palliative medicine rotation to highlight humanism. Impact was determined through thematic analysis of students' reflections. Design: Students elicited "what matters most" to patients, transcribing this plus a personal reflection. Using an inductive and iterative approach, 100 reflections were analyzed, developing codes then broader themes. Results: Four main themes (Getting to know the patient, Student Reaction, Building-blocks of patient-physician relationship, Student Personal Insights) were identified, with 15 subthemes. Conclusion: The power of uncovering patients' backgrounds and values was demonstrated, reinforcing a palliative medicine approach. Analysis showed a positive impact and the possibility of change to future practice. The intervention was feasible, well received, and encouraged reflection on the physician-patient relationship beyond the medical domain.

Therapeutic plasma exchange in the treatment of exertional heat stroke and multiorgan failure.

BACKGROUND: Exertional heat stroke (EHS) results in a constellation of systemic inflammatory responses resulting in multiorgan failure and an extremely high mortality. CASE DIAGNOSIS AND TREATMENTS: We present the case of an 11-year-old obese male who suffered EHS with rhabdomyolysis and concurrent renal, pulmonary, and hepatic failure. Conventional therapies including continuous veno-venous hemodiafiltration (CVVHDF) were ineffective in preventing ongoing deterioration in clinical status. Liver biopsy was reported as "extensive hepatocyte ballooning" and liver-kidney transplantation was tentatively planned. CONCLUSIONS: The addition of therapeutic plasma exchange using the Prismaflex® system (Gambro, Lakewood, CO, USA) resulted in a reversal of the inflammatory process and recovery from multiorgan failure. Liver biopsy was not a reliable indicator of irreversible hepatic injury.

Osteogenesis imperfecta due to compound heterozygosity for the LEPRE1 gene.

Osteogenesis imperfecta is a rare connective tissue disorder characterized by bone fragility and low bone density. Most cases are caused by an autosomal dominant mutation in either COL1A1 or COL1A2 gene encoding type I collagen. However, autosomal recessive forms have been identified. We present a patient with severe respiratory distress due to osteogenesis imperfecta simulating type II, born to a non-consanguineous couple with mixed African-American and African-Hispanic ethnicity. Cultured skin fibroblasts demonstrated compound heterozygosity for mutations in the LEPRE1 gene encoding prolyl 3-hydroxylase 1 confirming the diagnosis of autosomal recessive osteogenesis imperfecta type VIII, perinatal lethal type.
