Background: The management of indeterminate thyroid nodules (Bethesda III/IV) has evolved with molecular testing, aiming to reduce unnecessary surgeries. However, the comparative effectiveness of different platforms in influencing surgical decision-making remains unclear. This systematic review and meta-analysis evaluate the impact of molecular testing on surgical avoidance rates. Methods: A systematic literature search was conducted across eight electronic databases, including Embase, PubMed, and Cochrane Library, from January 2019 to December 2024, following PRISMA guidelines to encompass most recent advancements in the last 5 years. Studies evaluating Afirma Gene Expression Classifier (GEC), Afirma Genomic Sequencing Classifier (GSC), ThyroSeq V2, ThyroSeq V3, and ThyGenX/ThyraMIR were included. The primary outcome was surgical avoidance, analyzed using a random-effects model. Results: Thirty-one studies comprising 4464 indeterminate thyroid nodules met inclusion criteria. Pooled surgical avoidance rates varied across platforms: ThyroSeq V2 (50.3%, 95% CI: 20.8–79.6%), ThyroSeq V3 (62.5%, 95% CI: 54.8–70.0%), Afirma GEC (58.8%, 95% CI: 43.6–73.1%), Afirma GSC (50.6%, 95% CI: 34.3–66.8%), and ThyGenX/ThyraMIR (68.6%, 95% CI: 63.1–73.9%). ThyGenX/ThyraMIR had the highest surgical avoidance rate and lowest heterogeneity (I² = 51.2%), while ThyroSeq showed improvement from V2 to V3. Conclusions: Molecular testing reduces unnecessary thyroid surgeries, with avoidance rates ranging from 50.3% to 68.6%. While ThyGenX/ThyraMIR showed the highest avoidance rate, its limited representation warrants cautious interpretation. Standardized protocols are needed to optimize clinical application. Further prospective studies should compare platforms and assess long-term outcomes and cost-effectiveness.

Background: Paranasal sinus mucoceles, by virtue of extension into the orbit or cranial vault, can lead to significant ocular, nasal, or neural complications. There is limited comprehensive data on the presentation, management, and outcomes of cases with intraorbital or intracranial extension. A thorough analysis is essential to enhance clinical practices and improve patient outcomes. Objective: This retrospective case series investigates the clinical presentations, radiological features, and surgical outcomes of 10 patients with paranasal sinus mucoceles exhibiting intraorbital or intracranial extensions. Methods: Ten diagnosed cases of paranasal sinus mucoceles with intraorbital or intracranial extensions, as identified on CT or MRI imaging, were selected and retrieved from the electronic database of an academic-affiliated hospital from July 2013 to December 2023. Data were analyzed using descriptive statistics with IBM SPSS version 23.0 software. Results: The study revealed a mean patient age of 65 years, with females (60%) affected more than males (40%). The ethmoidal and frontal sinuses were predominantly involved, with varied clinical symptoms ranging from periorbital pain to visual disturbances. Radiologically, CT and MRI scans depicted extensive sinus involvement, often with intraorbital (50%), intracranial (20%), or combined (30%) extensions. Surgical interventions, primarily endoscopic sinus surgery, resulted in favorable outcomes, including symptom resolution, minimal complications, and no recurrence. Conclusion: This case series emphasizes the importance of thorough preoperative evaluation, individualized surgical approaches, and vigilant postoperative care in managing mucoceles with orbital and cranial involvement. Further research with larger cohorts and extended follow-up periods is essential to refine treatment strategies and enhance patient outcomes for this complex pathology.

Background/Objectives: Emergency airway management is a critical skill for healthcare professionals, particularly in life-threatening situations like “cannot intubate, cannot oxygenate” (CICO) scenarios. Errors and delays in airway management can lead to adverse outcomes, including hypoxia and death. Cognitive aids, such as checklists and algorithms, have been proposed as tools to improve decision-making, procedural competency, and non-technical skills in these high-stakes environments. This systematic review aims to evaluate the effectiveness of cognitive aids in enhancing emergency airway management skills among health professionals and trainees. Methods: A systematic search of MEDLINE, Embase, CINAHL, Cochrane Library, Scopus, Web of Science, and ClinicalTrials.gov was conducted from February to March 2024. Studies examining the use of cognitive aids, such as the Vortex method, the ASA difficult airway algorithm, and visual airway aids, in emergency airway scenarios were included. Outcomes assessed included decision-making speed, procedural success rates, and non-technical skills. Data were extracted using standardized protocols, and the quality of included studies was appraised. Results: Five studies met inclusion criteria, encompassing randomized controlled trials, controlled studies, and mixed-methods research. Cognitive aids improved decision-making times (reduced by 44.6 s), increased procedural success rates, and enhanced non-technical skills such as teamwork and crisis management. Participants reported reduced anxiety and improved confidence levels (self-efficacy scores increased by 1.9 points). The Vortex method and visual cognitive aids demonstrated particular effectiveness in simulated scenarios. Conclusions: Cognitive aids significantly enhance emergency airway management skills, improving performance, reducing errors, and increasing provider confidence. Integrating cognitive aids into training programs has the potential to improve patient safety and outcomes. Further research is needed to validate these findings in clinical settings and optimize cognitive aid design and implementation.

Background: Ki-67 immunostaining is commonly used in neuroendocrine tumors to estimate the proliferative index and for grading. This study investigates its association with the invasiveness of follicular-derived thyroid carcinomas (TCs). Methods: A retrospective analysis of patients with TC at three McGill University teaching hospitals between January 2018 and November 2023 was conducted. The inclusion criteria included patients with malignant thyroid tumors and accessible Ki-67 LI data from final pathology specimens. The data collected included patient demographics, Ki-67 LI values, and different invasiveness attributes, such as molecular mutations, the histological subtype, lymphovascular invasion (LVI), extrathyroidal extension (ETE), and positive lymph nodes (LNs). Results: In total, 212 patients met the inclusion criteria, of which 80.7% were females and 19.3% were males. The Ki-67 LI ranged from 1% to 30%, with the majority of the cases within the range of 1–15%. A significant association was observed between higher Ki-67 LI and high-risk histological subtypes of thyroid carcinoma (p < 0.001). Similarly, Ki-67 LI was significantly associated with LVI and positive LN metastasis (p < 0.001 and p = 0.036, respectively). However, no significant association was found between the Ki-67 LI and gene mutations or ETE (p = 0.133 and p = 0.190, respectively). Using percentiles to establish a cutoff, patients with a Ki-67 LI higher than 6.7 showed a higher likelihood of being associated with invasive features. Conclusion: Elevated Ki-67 LI can serve as an indicator of aggressiveness in follicular-derived TC, especially when associated with distinct histological subtypes, LVI and positive LNs.

Epistaxis, commonly referred to as nosebleeds, is a frequent clinical presentation with etiologies spanning from localized trauma to systemic conditions and medication effects. Despite its high prevalence, management approaches vary significantly depending on the cause and severity. To provide a comprehensive review of current management strategies for epistaxis, focusing on initial interventions, evaluation techniques, and preventive measures. A structured review of the literature was conducted to identify effective strategies for the initial management, evaluation, and prevention of epistaxis. Emphasis was placed on practical applications for clinicians in both emergency and outpatient settings. Initial Management: Direct pressure and topical vasoconstrictors remain the first-line interventions. Persistent cases may require nasal packing or cautery. Evaluation: Identification of underlying causes such as hypertension, coagulopathies, and structural nasal abnormalities is crucial, particularly in recurrent or severe cases. Laboratory tests and imaging may aid in diagnosis and management planning. Prevention: Patient education on nasal hygiene, avoidance of nasal trauma, and maintenance of a humidified environment are critical in reducing recurrence. Integrating effective initial management with thorough evaluation and preventive strategies significantly improves patient outcomes.
