Predictors for surgical intervention in orbital complications of pediatric rhinosinusitis.

OBJECTIVES: Orbital complications are the most common complication of acute rhinosinusitis, especially among pediatric patients. While most cases are treated with antibiotics alone, severe presentation may demand surgical intervention. Our goal was to determine which factors predict the need for surgery and to investigate the role of computerized tomography in the decision process. METHODS: A retrospective review of all children hospitalized between 2001-2018 with orbital complications of acute rhinosinusitis in a university-affiliated children's hospital. RESULTS: A total of 156 children were included. Mean age was 7.9 years (1-18 years). Twenty-three children (14.7%) were surgically treated, and the rest were conservatively treated. High fever, ophthalmoplegia and diplopia in association with minimal or no response to conservative treatment were predictive for surgical intervention, as well as higher inflammatory indices. Eighty-nine children (57%) underwent imaging during hospitalization. Presence of a subperiosteal abscess, as well as its size and its location were not found to be predictors for surgery. CONCLUSION: Clinical and laboratory findings in association with minimal or no response to conservative treatment predict the need for surgical intervention in cases of orbital complications of acute rhinosinusitis. As Computerized Tomography scans can have long-term implications in the pediatric population, caution and patience should be practiced when deciding on the timing of imaging in this population. Thus, close clinical and laboratory monitoring should lead the decision-making process in these cases and imaging should be reserved for when the decision for surgery has been made.

Implementation of a Novel Protocol for Preventing Venous Thromboembolism in Otolaryngology Patients.

OBJECTIVE: Venous thromboembolism (VTE) is a preventable cause of postoperative morbidity and mortality. The Caprini risk assessment model (CRAM) is a validated tool for estimating the risk for postoperative VTE. Previous studies demonstrated a low risk of VTE among otorhinolaryngology-head and neck surgery (ORL-HNS). Hence, our objective was to modify the CRAM-based protocol to be applicable for otolaryngology patients and assess protocol efficacy and safety. STUDY DESIGN: Observational pilot study conducted on ORL-HNS patients undergoing surgery. SETTING: University-affiliated tertiary care center. METHODS: We constructed a modified protocol based on the CRAM and previous reports in the ORL-HNS literature using a reduced postoperative anticoagulation regimen. Primary end point was symptomatic VTE up to 3 months after surgery. Main secondary outcome was postoperative bleeding. RESULTS: A total of 508 patients were enrolled. Of them, 48% underwent head and neck surgery, 18% direct laryngoscopy and transoral robotic surgery, 15% endoscopic sinus surgery, and 11% otology surgery. Adherence to the protocol was 79%. Mean follow-up time was 115 days (range, 30-448 days). Only 1 patient developed deep vein thrombosis, and none developed pulmonary embolism. Two patients had major bleeding not related to the use of anticoagulation. CONCLUSIONS: Our novel CRAM-based protocol appears to be efficacious and safe for VTE prevention in otolaryngology. A larger-scale study is required to validate these findings. LEVEL OF EVIDENCE: Level 2b.

Comparison of lateral neck X-ray to neck CT in patients with suspicious bone impaction: "Old habits die hard".

OBJECTIVE: Bone impaction (BI) is a common cause for emergency room visits. Among foreign bodies, fish bone is considered the most common. The sensitivity of symptoms in predicting BI is relatively low, making imaging a central tool to aid diagnosis. Current imaging practices include both neck plain film radiography and none-contrast CT scans of the neck. We evaluated the accuracy of neck plain film radiography and CT scans of the neck for the diagnosis of BI. METHODS: Retrospective review of all patients who presented to the emergency room between 2009 and 2016 with a suspicious history of BI whom underwent plain film neck radiography or CT. All Images were reviewed by two neuro-radiologist blinded to the clinical symptoms and findings. Symptoms, clinical findings and images results were compared to the final diagnosis. RESULTS: 89 patients (30.7%), out of 290 patients who presented with complaints of BI, were diagnosed with BI. Mean age was 44.7 years old. Plain film neck radiography failed to predict BI (sen. 14.4%, spe 89.8% accuracy 63.2%), neck CT has an improved accuracy and sensitivity in locating BI (sen. 83.3%, spe. 94.1% accuracy 92.5%). Interobserver agreement between the two neuro-radiologists was moderate (0.46) and substantial (0.77) in neck radiography and CT images, respectively. Neck radiography missed 60 (out of 61) oropharyngeal BI's. CONCLUSION: Neck radiography has high inter-observer variability and low sensitivity for the diagnosis of BI. Neck CT should be the first imaging modality in patients with suspicious complaints for BI and negative physical exam.

Survival benefit in bariatric surgery kidney recipients may be mediated through effects on kidney graft function and improvement of co-morbidities: A case-control study.

BACKGROUND: Data on the benefits of bariatric surgery for morbid obesity among kidney transplant recipients are scarce. OBJECTIVE: To examine the effect of bariatric surgery on graft function and survival and on obesity-related co-morbidities. SETTING: University hospital. METHODS: This case-control study used retrospectively collected data of all kidney recipients who underwent bariatric surgery in our institution between November 2011 and August 2016 (n = 30, 11 females). Nonbariatric operated kidney recipients matched for age, sex, and time elapsed since transplantation served as controls (n = 50, 23 females). Main outcomes were renal function, graft loss events, mortality, and obesity-related co-morbidities. RESULTS: The mean follow-up duration was 2.4 ± 1.3 years for both groups. At final follow-up, there was an increase in estimated glomerular filtration rates for the bariatric surgery group, and a decrease for the controls (13.4 ± 19.9 and -3.9 ± 15.8 mL/min/1.73 m2, respectively, P < .001). The chronic kidney disease classification improved in 9 bariatric surgery group patients and in 6 controls (P = .1). Two patients in the bariatric surgery group and 6 controls died. Total death or graft function loss during the follow-up was 6.7% and 16.7%, respectively (P = .3). The total numbers of co-morbidities and medications were lower in the bariatric surgery patients (-.7 and -2, respectively) and higher in the controls (+.3 and +1.1; P < .001) at study closure. CONCLUSIONS: There was an improvement in renal function, graft survival, and obesity-related co-morbidities among kidney transplant recipients who underwent bariatric surgery compared with those who did not. These findings support bariatric surgery in this population and warrant prospective studies.
