Objective For human papilloma virus–associated oropharynx squamous cell carcinoma (HPV+ OPSCC), we evaluated the distribution of neck-level lymph node (LN) metastasis, based on postsurgical histopathology, and the incidence of and risk factors for occult LN metastases, as these patterns need clarification for this newer cancer subset. Study Design Retrospective cohort study. Setting National Cancer Database (NCDB). Methods We analyzed 2358 patients in the NCDB with HPV+ OPSCC who underwent neck dissection (ND) from 2010 to 2015. Incidence and distribution of LN metastases were calculated for neck levels I to V. Variables associated with occult LN metastasis were assessed by multivariate logistic regression. Results In therapeutic NDs (n = 1935), the following proportions of positive LNs were found: level I, 9.0% (n = 175); level II, 81.0% (n = 1568); level III, 29.6% (n = 573); level IV, 11.9% (n = 230); and level V, 4.9% (n = 95). In elective NDs (n = 423), occult-positive LNs were found in 35.8% (n = 152), with the following proportions by level: level I, 3.3% (n = 14); level II, 26.9% (n = 114); level III, 8.7% (n = 37); level IV, 4.0% (n = 17); and level V, 0.2% (n = 1). The presence of occult LNs was independently associated with a Charlson-Deyo score of 1 (odds ratio, 2.26; 95% CI, 1.18-4.31; P = .014) and lymphovascular invasion (odds ratio, 5.91; 95% CI, 3.21-11.18; P < .001). Occult LN metastases were not significantly associated with pT classification, primary site, or number of LNs resected. Conclusion For HPV+ OPSCC, occult nodal disease is common. Therapeutic NDs should encompass at least levels II, III, and IV and possibly I, whereas elective NDs could possibly encompass levels II and III. Level of Evidence 4.
Objectives/Hypothesis Hospital length of stay (LOS) and throughput are critical issues for hospitals. Late hospital discharges contribute to bottlenecks in the emergency department, overcrowd surgical and procedural areas, and limit patient tertiary‐care center transfers. Our goal was to increase discharge by noon (DCBN) percentage from 8% to over 50% in a sustainable manner. Study Design Retrospective Review. Methods We used a multiple time series design and a quality improvement approach. An interdisciplinary improvement team (IIT) identified the main causes contributing to late discharge and then developed and implemented multiple interventions to increase the percentage of DCBN. Admissions and discharge information were obtained for all patients in the otolaryngology service (January 2014–September 2017). The intervention was implemented in July 2015. The primary outcome was the percentage of DCBN per month. Secondary outcomes were LOS, case‐mix index (CMI), patient experience, and 30‐day readmissions. We analyzed the impact of our intervention and outcomes at the preintervention, peri‐intervention, and postintervention periods. Results One thousand four hundred sixty‐four admissions to the otolaryngology service were included. Throughout the intervention period, the percentage of patients DCBN increased. Analysis of the intervention showed significant DCBN change of 15% in the first versus 42% in the last 12‐months (P < .001), and shorter LOS (−1.4 days, P < .001) and lower CMI (−0.6, P < .001) in the DCBN group. Patient satisfaction scores improved by 4% (P < .05), and no difference in 30‐day readmission rates (P = .29) was shown. Conclusions This multifaceted intervention improved early discharge and patient experience. Our checklist of key behaviors could be applied throughout other services and hospitals with reproducible success. Level of Evidence 4 Laryngoscope, 131:E76–E82, 2021
BACKGROUND: Implantable medical devices and hardware are prolific in medicine, but hardware associated infections remain a major issue. OBJECTIVE: To develop and evaluate a novel, biologic antimicrobial coating for medical implants. METHODS: Electrochemically compacted collagen sheets with and without crosslinked heparin were synthesized per protocol developed by our group. Sheets were incubated in antibiotic solution (gentamicin or moxifloxacin) overnight, and in vitro activity was assessed with five-day diffusion assays against Pseudomonas aeruginosa. Antibiotic release overtime from gentamicin infused sheets was determined using in vitro elution and high performance liquid chromatography (HPLC). RESULTS: Collagen-heparin-antibiotic sheets demonstrated larger growth inhibition zones against P. aeruginosa compared to collagen-antibiotic alone sheets. This activity persisted for five days and was not impacted by rinsing sheets prior to evaluation. Rinsed collagen-antibiotic sheets did not show any inhibition zones. Elution of gentamicin from collagen-heparin-gentamicin sheets was slow and remained above the minimal inhibitory concentration for gentamicin sensitive organisms for 29 days. Conversely, collagen-gentamicin sheets eluted their antibiotic payload within 24 hours. Overall, heparin associated sheets demonstrated larger inhibition zones against P. aeruginosa and prolonged elution profile via HPLC. CONCLUSION: We developed a novel, local antibiotic delivery system that could be used to coat medical implants/hardware in the future and reduce post-operative infections.
Objective To examine the diagnostic value of the sentinel lymph node biopsy in pediatric through young adult head and neck melanocytic tumors of unknown malignant potential. Study Design Retrospective case series. Setting Single academic institution. Subjects and Methods Demographics, histology, and outcomes were examined in 14 patients aged 4 to 24 years with head and neck melanocytic tumors of unknown malignant potential. Information on age at diagnosis, primary lesion characteristics, and sentinel lymph node biopsy were compared. Results Of 14 patients meeting criteria for head and neck melanocytic tumors of unknown malignant potential, 8 patients underwent sentinel lymph node biopsy (57%). Of those, 4 biopsies (50%) had positive sentinel nodes. All patients undergoing sentinel lymph node biopsy had primary lesions greater than 1 mm depth or mitotic rate of at least 1 mitosis per mm 2 . No patients had recurrence of their primary lesion at time of follow-up. Conclusion Our data show a high rate of node-positive sentinel lymph node biopsy for pediatric and young adult head and neck patients with melanocytic tumors of unknown malignant potential, supporting the value of sentinel lymph node biopsy in this population.
