AI Article Synopsis
- There is a rising concern about methicillin-resistant Staphylococcus aureus (MRSA) infections in community settings, prompting a study to assess changes in infection types following open fractures.
- A retrospective study on 189 patients revealed that 10% developed infections, with MRSA found in 25% of those infections and a notable presence of Gram-negative organisms.
- The findings suggest a significant incidence of MRSA and Gram-negative infections, indicating the potential need for updates to current antibiotic prophylaxis regimens for open fractures.
Article Abstract
Background: There have been increasing reports of methicillin-resistant Staphylococcus aureus (MRSA) infections in the community, but it is unclear whether infectious organisms in open fracture infections have changed and if our current regimen of antibiotic prophylaxis is therefore obsolete.
Questions/purposes: We determined the recent incidence of MRSA and Gram-negative organism infections after open fractures.
Methods: We performed a retrospective cohort study on 189 patients with 202 open fractures treated from 2009 to 2010. During the followup, patients were evaluated for signs of infection using the Centers for Disease Control and Prevention criteria. We determined the organisms using routine microbiology culture. The minimum followup was 3 months (median, 47 months; range, 3-108 months).
Results: Of the 202 open fractures, 20 (10%) developed infections. The most common organism was Staphylococcus, whereas five (25%) of those infected were positive for MRSA, and 11 (55%) of those with infection were cultured for at least one Gram-negative organism. Six (30%) open fractures had infections that grew out multiple organisms. The incidence of MRSA infections in our open fracture population was 2.5%.
Conclusions: There is a high incidence of MRSA and Gram-negative infections after open fractures, which may indicate that current antibiotic regimens need to be changed.
Level Of Evidence: Level IV, retrospective case-series. See the Guidelines for Authors for a complete description of levels of evidence.

The rising prevalence of multidrug-resistant (MDR) Gram-positive bacteria threatens the effectiveness of current antibiotic therapies. However, the development of new antibiotics has stagnated in recent years, highlighted the critical need for the discovery of innovative antimicrobial agents. This study aims to evaluate the antibacterial activity of naphthoquinones derived from Arnebia euchroma (Royle) Johnst (ADNs) and elucidate their underlying mechanisms.

Traumatic cerebrospinal fluid (CSF) leakage from skull base fractures increases the risk of bacterial meningitis, which is associated with a high mortality rate in adults, and commonly results in severe neurological outcomes. While most cases of CSF leakage occur within three months post-injury and generally resolve spontaneously, delayed-onset meningitis remains a challenging complication. Herein, we report a rare case of severe bacterial meningitis with an intraventricular abscess one year following a frontal skull base fracture, despite no CSF leak.

We report a case of coexisting cold agglutinin and cryoglobulin in a patient with severe anemia following COVID-19 infection, in whom direct antiglobulin testing revealed C3d positivity and immunoglobulin G negativity. There was no evident hemolytic anemia, thrombosis, or clinically significant IgM monoclonal gammopathy. The anemia improved with folic acid supplementation alone accompanied by a decrease of the cold agglutination titer, and the direct antiglobulin test became negative.

Miller Fisher syndrome (MFS) is a rare Guillain-Barré syndrome (GBS) variant. The global incidence of GBS is approximately one to two in 100,000 children (aged 0 to 15 years) per year. Miller Fisher syndrome represents a further small subset, with the incidence being one to two in 1,000,000 children.
