Sinonasal malignancies rare and pathologically diverse and make up less then 1% of all malignancies. Due to their anatomical location, they can cause significant morbidity with involvement of surrounding critical structures. They often present at a late stage with insidious onset of symptoms. Treatment of sinonasal malignancies is challenging and they often require a multimodality approach with surgery, radiation, and chemotherapy. see more Outcomes are poor with 5-year overall survival around 32%, but this varies greatly depending on histologic subtype. There is an urgent need for more randomized controlled trials to better define the appropriate therapeutic regimens and to improve clinical outcomes.Head and neck squamous cell carcinoma (HNSCC) treatment is often associated with high morbidity especially in the recurrent and/or metastatic (R/M) setting, limiting effective treatment options. Local disease control is important. Therefore, local therapies including reirradiation and salvage surgery, either alone or in combination with systemic treatment, may be used for selected patients with R/M HNSCC. Although chemotherapy and targeted agents have modest efficacy in HNSCC, the advent of immunotherapy has revolutionized the treatment paradigm of R/M HNSCC. Multiple trials have resulted in the past 5 years advocating for its use alone or in combination with chemotherapy.Veterinary practices must continuously change to meet the needs of their clients, maintain the standard of patient care, and remain profitable. Ultimately, all changes boil down to the incorporation of new behaviors by the practice employees. However, human nature tends to resist change and most of the change initiatives will fail unless they are guided by a well-defined process of generating a sense of urgency, recruiting a team of opinion leaders, involving the employees, and removing barriers to change. This chapter reviews the barriers to change and will outline a proven process for enacting change in your team.Discussing medical quality starts with defining quality. Human health care publications identify safety, timeliness, efficiency, effectiveness, equity, and patient centeredness as important components of medical quality. Safety is foremost as medical errors are a leading cause of patient death. Studies examining patient outcomes have found that culture is critical. Cultures that emphasize communication, open discussion, and continuous improvement lead to improved patient survival and decreased medical errors. Leadership, training, staff meetings, and processes for gathering input all contribute to a culture of safety. Discussing medical errors with clients is difficult but can be made more manageable with a 6-step process.In today's veterinary practices, 5 generations (traditionalists, baby boomers, Generation X, millennials, and Generation Z), each with a unique way of looking at the world, are trying to work together effectively. Common strategies for managing this multigenerational workplace include villainizing "other" generations or merely tolerating their presence. Conflict, disagreements, and misunderstanding often get in the way of practicing quality medicine. Thus, veterinary health professionals must develop strategies that allow for effective communication, not only within the practice but also with clients, vendors, and other stakeholders, a strategy that builds bridges among the generations through engagement, regardless of generation.
We aimed to assess and compare the analgesic efficacies and adverse effects of ketamine administered through a breath-actuated nebulizer at 3 different dosing regimens for emergency department patients presenting with acute and chronic painful conditions.

This was a prospective, randomized, double-blinded trial comparing 3 doses of nebulized ketamine (0.75 mg/kg, 1 mg/kg, and 1.5 mg/kg) administered through breath-actuated nebulizer in adult emergency department patients aged 18 years and older with moderate to severe acute and chronic pain. The primary outcome included the difference in pain scores on an 11-point numeric rating scale between all 3 groups at 30 minutes. Secondary outcomes included the need for rescue analgesia (additional doses of nebulized ketamine or intravenous morphine) and adverse events in each group at 30 and 60 minutes.

We enrolled 120 subjects (40 per group). The difference in mean pain scores at 30 minutes between the 0.75 mg/kg and 1 mg/kg groups was 0.25 (95% confidence interval [CI] 1.28 to 1.78); between the 1 mg/kg and 1.5 mg/kg groups was-0.225 (95% CI-1.76 to 1.31); and between the 0.75 mg/kg and 1.5 mg/kg groups was 0.025 (95% CI-1.51 to 1.56). No clinically concerning changes in vital signs occurred. No serious adverse events occurred in any of the groups.

We found no difference between all 3 doses of ketamine administered through breath-actuated nebulizer for short-term treatment of moderate to severe pain in the emergency department.

To determine the diagnostic accuracy of point-of-care ultrasound (POCUS) performed by experienced clinician sonologists compared to radiology-performed ultrasound (RADUS) for detection of clinically important intussusception, defined as intussusception requiring radiographic or surgical reduction.

We conducted a multicenter, noninferiority, observational study among a convenience sample of children aged 3 months to 6 years treated in tertiary care emergency departments across North and Central America, Europe, and Australia. The primary outcome was diagnostic accuracy of POCUS and RADUS with respect to clinically important intussusception. Sample size was determined using a 4-percentage-point noninferiority margin for the absolute difference in accuracy. Secondary outcomes included agreement between POCUS and RADUS for identification of secondary sonographic findings.

The analysis included 256 children across 17 sites (35 sonologists). Of the 256 children, 58 (22.7%) had clinically important intussusception.
