RESUMEN
OBJECTIVE: To determine factors predicting overnight admission after sialolithectomy. STUDY DESIGN: Quality outcome database research. SETTING: The National Surgical Quality Improvement Program American College of Surgeons Participant User Files. METHODS: Current Procedural Terminology (CPT) codes 42330, 42335, and 42340 between 2007, and 2020 resulted 916 cases. Correlations between perioperative factors and overnight admission (ie, length of stay >0 days) were tested. Cases were stratified into endoscopic (ES) and nonendoscopic (NES) procedures using concurrent CPT codes 42660, 42669, and 42650. RESULTS: After sialolithectomy, 13.7% (126 cases) were admitted at least overnight. Upon multivariate analysis, wound Class 4 (odds ratio [OR]: 2.15, 95% confidence interval: 1.05, 4.40), American Society of Anesthesiologists (ASA) 3 classification (OR: 2.17, 1.06-4.46, P = .035), and the operative time (OR: 1.01 [1.01-1.01], P < .001) correlated with overnight stay; while Class 2 wounds had a lower risk of overnight admission (OR: 0.31 [0.12-1.63], P < .001). The ES cohort had longer operative times (56.1 vs 73.6 minutes). In the NES cohort's multivariate analysis, ASA III (OR: 2.459 [1.13, 5.34], P < .001) and operative time (OR: 1.01 [1.01, 1.02], P < .001) correlated with overnight stay while Class 2 wound classifications protected against overnight stay (OR: 0.28 [0.15, 0.52], P < .001). CONCLUSION: This study highlights the correlation between intraoperative complexity, as operative time, wound classification and ASA Class 3, and the need for admission after a typically ambulatory sialolithectomy. The significantly longer operative time with evidence of a shorter length of stay in ES cases suggests a valuable trade off, within the limits of indication.
RESUMEN
OBJECTIVE: Tracheostomy is performed for various indications ranging from prolonged ventilation to airway obstruction. Many factors may play a role in the incidence of complications in the immediate post-operative period including patient-related factors. Chronic obstructive pulmonary disease and asthma are some of the most common pulmonary pathologies in the United States. The relationship between obstructive pulmonary diseases and acute post-tracheostomy complications has been incompletely studied. DESIGN: A retrospective chart review was designed in order to answer these objectives. Medical records were reviewed for the technique used, complications, and contributing patient factors. Post-operative complications were defined as any tracheostomy-related adverse event occurring within 14 days. SETTING: The study took place at an academic comprehensive cancer. PARTICIPANTS: Inclusion criteria included patients from January 2017 through December 2018 who underwent a tracheostomy. Exclusion criteria included presence of stomaplasty, total laryngectomy, and tracheostomies performed at outside hospitals. MAIN OUTCOME MEASURES: Patient factors examined included demographics, comorbidities, and body mass index with the primary outcome measured being the rate of tracheostomy complications. RESULTS: The most common indication for tracheostomy among the 321 patients that met inclusion criteria was airway obstruction or a head and neck cancer surgical procedure. Obstructive sleep apnea was associated with acute complications in bivariate analysis (29.4% complications, p = .003). Chronic obstructive pulmonary disease and asthma were not associated with acute complications in bivariate analysis (11.6% complications, p = .302). Among the secondary outcomes measured, radiation was associated with early complications occurring in post-operative days 0-6 (1.1%, p = .029). CONCLUSION: Patients with obstructive sleep apnea may have a higher risk of acute post-tracheostomy complications that might be due to the patient population at risk for obstructive sleep apnea. Patients with obstructive pulmonary pathologies such as asthma or chronic obstructive pulmonary disorder did not have an elevated risk of complications which is clinically significant when considering the utility of ventilation and tracheostomy in the management of acute respiratory failure secondary to these conditions.

OBJECTIVE: Difficult airways can be associated with significant morbidity and mortality, particularly in the event of a delay in securing the airway. To improve the airway metrics at our institution, we implemented a multidisciplinary team of airway providers to respond to difficult and emergent airways, or the Difficult Airway Response Team (DART). The purpose of the present study is to assess the feasibility of a DART program at a tertiary care center. STUDY DESIGN: A retrospective study evaluating the outcomes of emergent airway cases using the DART protocol. SETTING: Single tertiary academic care center. METHODS: In August 2019, a DART program was implemented at a tertiary academic medical center. In order to assess the feasibility and effectiveness of this system, data were collected to assess DART outcomes through chart review and surveys following each event, and analyzed in Microsoft Excel. RESULTS: A total of 161 DART events (average 4.6/month) took place from August 2019 to June 2022. Anesthesiologists secured the airway in 71 events (51%), otolaryngologists in 38 (27%), and pulmonary/critical care in 12 (9%). Seventy-three activations were not labeled as a difficult airway. Pre-DART, 19 cases required more than 3 attempts to secure the airway compared to 11 cases after DART. Transoral intubation was the most common intervention. Thirteen cases required surgical intervention. CONCLUSION: Implementing a multidisciplinary team-based approach for managing emergent difficult airways at a tertiary care institution was feasible and resulted in a decreased number of airway attempts in difficult airway patients. Continuous process improvement is essential for the ongoing enhancement of DART systems.

Asthma is a chronic inflammatory disease of the airway that leads to airway obstruction via bronchoconstriction, edema, and mucus hypersecretion. The National Asthma Education and Prevention Program has outlined evidence-based guidelines to standardize asthma therapy and improve outcomes. The initial recommendation of choice for persistent asthmatic patients is an inhaled corticosteroid (ICS). Long-acting beta-2 agonists in combination with ICS, oral corticosteroids, leukotriene modifiers, and anti-IgE therapeutic options can be considered for patients with persistent or worsening symptoms. Many novel therapies are being developed, with an emphasis on anti-inflammatory mechanisms, gene expression, and cytokine modification.

PURPOSE: The increasing incidence of IgE-mediated food allergy has led to further study of this atopic disease. RECENT FINDINGS: Food allergy represents a failure to attain oral tolerance marked by a pronounced Th2 versus T-regulatory cell response. The gold standard for the diagnosis of food allergy is a double-blind, placebo-controlled food challenge. Evidence supports breastfeeding to prevent certain atopic diseases but there is no support for delayed food introduction or maternal diet restrictions during pregnancy or lactation. There is no cure for food allergies. The mainstay of therapy is avoidance and management of severe reactions with self-injectable epinephrine. Other promising therapies include oral immunotherapy and sublingual immunotherapy. SUMMARY: The mechanism of IgE-mediated food allergy is better understood but further research is needed to prevent and treat food allergies.

BACKGROUND: Lymphatic malformation is a common benign mass in children and adults and is representative of a derangement in lymphangiogenesis. These lesions have high recurrence rates and significant morbidity associated with surgery. Several sclerotherapy regimens have been developed clinically to treat lymphatic malformations; however, an animal model has not been developed that is adequate to test the efficacy of image-guided therapeutic interventions. OBJECTIVE: To develop an animal model suitable for evaluation of percutaneous treatments of lymphatic malformations. MATERIALS AND METHODS: Male Harlan Sprague-Dawley rats (n = 9) received two US-guided injections of Incomplete Freund's Adjuvant (IFA) over a 2-week period. All nine rats were injected twice into the peritoneum (IP); a subgroup (n = 3) received additional injections into the neck. Three animals that received IP injections of saline were used as controls. The injection sites were monitored for the development of lesions by high-resolution ultrasonography at 2-week intervals for 100 days. High-resolution (4.7 Tesla) magnetic resonance imaging was then performed on two animals noted to have developed masses. The rats were sacrificed and histologic examination of the identified lesions was performed, including immunohistochemical staining for vascular (CD31) and lymphatic (Flt-4 and Prox-1) endothelium. RESULTS: All animals injected with IFA developed cystic lesions. The three animals injected at dual sites were noted to have both microcystic and macrocystic malformations in the neck and microcystic plaque-like lesions in the peritoneum. The macrocystic malformations (> or =5 mm) in the neck were detected by ultrasonography and grossly later during necropsy. Histopathologic analysis revealed the cystic spaces to be lined by lymphatic endothelium supported by a connective tissue stroma. Control animals did not exhibit detectable lesions with either ultrasonography or necropsy. CONCLUSION: This model represents a promising tool for translational development of image-guided interventions for lymphatic malformations. It may also serve as a model for the study of lymphangiogenesis and the development of anti-lymphangiogenic therapies.
