Successful treatment of severe immune checkpoint inhibitor associated autoimmune hepatitis with basiliximab: a case report.

Immune checkpoint inhibitors (ICIs) targeting programmed cell death-1 (PD-1) and its corresponding ligand PD-L1 are being increasingly used for a wide variety of cancers, including refractory sarcomas. Autoimmune hepatitis is a known side effect of ICIs, and is typically managed with broad, non-specific immunosuppression. Here, we report a case of severe autoimmune hepatitis occurring after anti-PD-1 therapy with nivolumab in a patient with osteosarcoma. Following prolonged unsuccessful treatment with intravenous immunoglobulin, steroids, everolimus, tacrolimus, mycophenolate, and anti-thymoglobulin, the patient was eventually treated with the anti-CD25 monoclonal antibody basiliximab. This resulted in prompt, sustained resolution of her hepatitis without significant side effects. Our case demonstrates that basiliximab may be an effective therapy for steroid-refractory severe ICI-associated hepatitis.

Laryngeal Ultrasound Detects Vocal Fold Immobility in Adults: A Systematic Review.

Laryngeal ultrasound (US) is becoming widely accepted for assessing true vocal fold immobility (TVFI), a potential complication of laryngeal and thyroid surgery. The objective of this project is to perform a systematic review and meta-analysis of pooled evidence surrounding laryngeal US as a modality for diagnosing TVFI in adults at risk for the condition in comparison to laryngoscopy as a gold standard. Medical subject heading terms were used to search MEDLINE, Embase, Google Scholar, Web of Science, and the Cochrane Library for relevant citations from January 1, 2000, to June 30, 2020. Studies were included if they involved patients 16 years and older, where laryngeal US was compared to laryngoscopy for TVFI. Studies were excluded if there were insufficient data to compute a sensitivity/specificity table after attempting to contact the authors. Case reports, and case series were also excluded. The initial search returned 1357 citations. Of these, 109 were selected for review utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Thirty citations describing 6033 patients were included in the final meta-analysis. A bivariate random effects meta-analysis was performed, revealing a pooled sensitivity for laryngeal US of 0.95 (95% confidence interval [CI] 0.88-0.98), a specificity of 0.99 (95% CI 0.97-0.99), and a diagnostic odds ratio of 1328.2 (95% CI 294.0-5996.5). The area under the curve of the hierarchical summary receiver operating characteristic curve was 0.99 (95% CI 0.98-1.00). Laryngeal US demonstrates high sensitivity and specificity for detecting VFI in the hands of clinicians directly providing care to patients.

Assessment of Vocal Cord Motion Using Laryngeal Ultrasound in Children: A Systematic Review and Meta-Analysis.

OBJECTIVES: Laryngeal ultrasound is a nonirradiating, noninvasive method for assessing the upper airway in children. This systematic review and meta-analysis examine available evidence for accuracy of laryngeal ultrasound in diagnosing vocal cord immobility in infants and children after surgery and trauma affecting the vocal cords. DESIGN: Medical subject heading terms were used to search MEDLINE, Embase, Google Scholar, Web of Science, and the Cochrane Library for relevant citations. Publications from January 1, 2000, to June 30, 2020 were included in the search strategy. Study inclusion criteria consisted of randomized control trials and nonrandomized retrospective or prospective observational studies where vocal cord motion was evaluated by laryngeal ultrasound and compared with a reference test. Studies were excluded if there was insufficient data to compute a sensitivity/specificity table. Case reports, case series less than 10, and manuscripts not published in English were also excluded. PATIENTS: Studies which included subjects younger than or equal to 18 years were considered for full article review. SETTINGS: No restrictions on study settings were imposed in this systematic review. MEASUREMENTS AND MAIN RESULTS: The initial search returned 1,357 citations. After de-duplication, abstract, and full review, eight citations were included in the final meta-analysis. A bivariate random-effects meta-analysis was performed, which revealed a pooled sensitivity for laryngeal ultrasound in detecting vocal cord immobility of 91% (95% CI, 83-95%), specificity of 97% (95% CI, 82-100%), diagnostic odds ratio 333.56 (95% CI, 34.00-3,248.71), positive likelihood ratio 31.58 (95% CI, 4.50-222.05), and negative likelihood ratio 0.09 (95% CI, 0.05-0.19). CONCLUSIONS: Laryngeal ultrasound demonstrates high sensitivity and specificity for detecting vocal cord motion in children in a wide range of clinical settings. Laryngeal ultrasound offers a low-risk imaging option for assessing vocal cord function in children compared with the current gold standard of laryngoscopy.

Postoperative antibiotics are not associated with decreased wound complications among patients undergoing appendectomy for complicated appendicitis.

BACKGROUND: The objective of this study was to determine the role of postoperative antibiotics in reducing complications in patients undergoing appendectomy for complicated appendicitis. METHODS: We performed a 5-year retrospective cohort study of adult patients who underwent appendectomy for acute appendicitis. Patients with complicated appendicitis (perforated or gangrenous) were analyzed on the basis of whether they received postoperative antibiotics. Main outcome measures were wound complications, length of stay (LOS), and readmission to hospital. RESULTS: Of 410 patients with complicated appendicitis, postoperative antibiotics were administered to 274 patients (66.8%). On univariate and multivariate analyses, postoperative antibiotics were not associated with decreased wound complications or readmission, but independently predicted an increased LOS (P = .01). CONCLUSIONS: Among patients with complicated appendicitis, postoperative antibiotics were not associated with a decrease in wound complications but did result in an increased hospital LOS.
