Comparative StudyComparative Effectiveness of Ceftriaxone plus Metronidazole versus Anti-Pseudomonal Antibiotics for Perforated Appendicitis in Children.
Background: Appendicitis is the most common pediatric surgical emergency and one of the most common indications for antibiotic use in hospitalized children. The antibiotic choice differs widely across children's hospitals, and the optimal regimen for perforated appendicitis remains unclear. Methods: We conducted a retrospective cohort study comparing initial antibiotic regimens for perforated appendicitis at a large tertiary-care children's hospital. Children hospitalized between January 2011 and March 2015 who underwent surgery for perforated appendicitis were identified by ICD-9 codes with confirmation by chart review. ⋯ A post-operative complication occurred in 37 (14.7%) of the CTX/MTZ group versus 18 (17.8%) of the anti-pseudomonal group. Antibiotic-related complications occurred in 4.4% of children on CTX/MTZ and 6.9% of children on anti-pseudomonal antibiotics (p = 0.32). In a multivariable logistic regression model adjusting for sex, age, ethnicity, and duration of symptoms prior to presentation, the adjusted odds ratio for post-operative complications in children receiving anti-pseudomonal antibiotics was 1.25 (95% confidence interval 0.66-2.40). Conclusion: Post-operative complication rates did not differ for children treated with CTX/MTZ versus a broader-spectrum regimen.

Risk Factors for Post-Operative Sepsis and Septic Shock in Patients Undergoing Emergency Surgery.
Background: Sepsis after emergency surgery is associated with a higher mortality rate than elective surgery, and total hospital costs increase by 2.3 times. This study aimed to identify risk factors for post-operative sepsis or septic shock in patients undergoing emergency surgery. Methods: A retrospective cohort analysis was performed using the National Surgical Quality Improvement Program (NSQIP) by identifying patients undergoing emergency surgery between 2012 and 2015 and comparing those who developed post-operative sepsis or septic shock (S/SS) with those who did not. Patients with pre-operative sepsis or septic shock were excluded. ⋯ Patients undergoing biliary surgery (OR 0.38; CI 0.30-0.48; p < 0.0001) were less likely to develop S/SS. Conclusions: Risk factors for the development of sepsis or septic shock are ASA PS class 2 or higher, partially or totally dependent functional status, and male gender. Emergency pancreatic or small intestinal procedures may confer a higher risk. Greater vigilance and early post-operative screening may be of benefit in patients with these risk factors.

Case ReportsActinomyces turicensis Necrotizing Soft-Tissue Infection of the Thigh in a Diabetic Male.
Background: Necrotizing soft-tissue infections are a devastating infection that is rarely caused by Actinomyces spp. Case Report: A 45-year-old obese previously healthy male presented to the emergency department with diabetic ketoacidosis. ⋯ Conclusion: Actinomyces turicensis may be the pathogen causing certain necrotizing soft-tissue infections. Clinicians should consider the possibility that this organism represents a true pathogen and not colonization/contamination.
