RESUMO
Objective: Functional endoscopic sinus surgery is a commonly performed otolaryngologic procedure that often uses the microdebrider device for tissue removal. Given the ubiquitous nature of the instrument, we sought to better define the patterns of device failure using the postmarket surveillance openFDA database. Methods: The openFDA database was queried for all microdebrider-related adverse events from January 1, 2000 to November 1, 2020. Descriptive information on the nature of device failure and any associated patient injury was compiled. Reports not directly related to device failure were excluded from the analysis. Results: A total of 641 events were included in the analysis. The most common device failure was overheating (n = 348, 54.3%), followed by material separation (n = 173, 27%), and inconsistent device activation (n = 52, 8.1%). Of the reported events, the vast majority did not result in patient harm (n = 579, 90.3%). On review of the remaining cases, only 24 events (3.7%) resulted in true harm to the patient, defined as a temporary or permanent injury or >30 min of additional anesthesia time. Of these cases, the need to reschedule surgical cases (n = 5, 0.8%), retained foreign body (n = 5, 0.8%), and thermal tissue injury (n = 3,0.5%) were the most common. Five patients suffered an injury due to surgeon error unrelated to device malfunction (n = 5, 0.8%). Conclusions: Microdebrider device failures are extremely rare. When they do occur, less than 10% result in patient harm. In cases of patient harm related to microdebrider failure, preoperative testing of the device before use could prevent many of the reported malfunctions.
RESUMO
OBJECTIVES: The popularity of mountain biking (MTB) in the United States has risen in recent years. We sought to identify the prevalence and distribution of MTB associated head and neck injuries presenting to emergency departments across the U.S. and identify risk factors for hospital admission in this patient population. METHODS: The National Electronic Injury Surveillance System (NEISS) was queried for MTB related injuries of the head and neck from 2009 to 2018, with analysis for incidence, age, gender, anatomic site, and diagnoses. RESULTS: A total of 486 cases were identified, corresponding to an estimated 18 952 head and neck MTB related ED visits. Patients were predominantly male (80.7%) and white (69.8%) with a median age of 35 years (interquartile range, 21-46 years). A majority (88.4%) of patients were released from the ED, but a significant proportion of patients were admitted (9.2%) or transferred (1.2%). The most common facial fractures were facial/not specified (35%), nasal bone (29%), mandible (15%), orbit (12%), and zygomaxillary complex (9%). The greatest predictors of hospital admission/transfer were injury to the mouth or neck and avulsion-type injury (P < .001). CONCLUSIONS: MTB results in a significant number of traumatic head and neck injuries nationwide. Patients are primarily adult, white males. The majority of injuries result in discharge from the ED, however a small amount of these patients experience significant morbidity necessitating hospital admission. Understanding the distribution of MTB head and neck injuries may aid in the clinical evaluation of these patients. LEVEL OF EVIDENCE: 4.

PURPOSE: Systemic juvenile idiopathic arthritis is a chronic pediatric disease. The initial clinical presentation can mimic other pediatric inflammatory conditions, which often leads to significant delays in diagnosis and appropriate therapy. SJIA biomarker development is an unmet diagnostic/prognostic need to prevent disease complications. EXPERIMENTAL DESIGN: We profiled the urine peptidome to analyze a set of 102 urine samples, from patients with SJIA, Kawasaki disease (KD), febrile illnesses (FI), and healthy controls. A set of 91 plasma samples, from SJIA flare and quiescent patients, were profiled using a customized antibody array against 43 proteins known to be involved in inflammatory and protein catabolic processes. RESULTS: We identified a 17-urine-peptide biomarker panel that could effectively discriminate SJIA patients at active, quiescent, and remission disease states, and patients with active SJIA from confounding conditions including KD and FI. Targeted sequencing of these peptides revealed that they fall into several tight clusters from seven different proteins, suggesting disease-specific proteolytic activities. The antibody array plasma profiling identified an SJIA plasma flare signature consisting of tissue inhibitor of metalloproteinase-1 (TIMP1), interleukin (IL)-18, regulated upon activation, normal T cell expressed and secreted (RANTES), P-Selectin, MMP9, and L-Selectin. CONCLUSIONS AND CLINICAL RELEVANCE: The urine peptidomic and plasma protein analyses have the potential to improve SJIA care and suggest that SJIA urine peptide biomarkers may be an outcome of inflammation-driven effects on catabolic pathways operating at multiple sites.
