Ongoing resistance developments against antibiotics that also affect last-resort antibiotics require novel antibacterial compounds. Strategies to discover such novel structures have been dimerization or hybridization of known antibacterial agents. We found novel antibacterial agents by dimerization of indols and hybridization with carbazoles.

Article Synopsis
  • There's a growing problem with bacteria becoming resistant to existing antibiotics, making the discovery of new antibacterial agents crucial.
  • Researchers found new small-molecule antibacterial agents that can be made through a simple two-step process, and their effectiveness varies based on how they're structured.
  • Some of these new compounds significantly enhance the effectiveness of tetracycline, especially those with a 3-methoxy group, showing promise for dual-action antibacterial treatments.

Background: Lack of insurance has been shown to lead to delays in seeking care as well as fewer preventive medicine visits and poorer overall health status.

Purpose: To investigate the effects of insurance status on the timing and treatment of patients with bucket-handle meniscus tears.

Study Design: Cohort study; Level of evidence, 3.

Since 1887, approximately 50 cases of an intra-articular patellar dislocation have been reported in the worldwide literature. The vast majority of patients required an open reduction of the patella or closed reduction under general anesthesia. This injury has never been reported in association with a coronal shear fracture of the femoral condyle.

Patellar sleeve fractures are easily missed injuries since plain radiographs may not show a bony fragment at the time of injury. Failure to diagnose these injuries can result in patellar instability, extensor lag, and anterior knee pain. We report a novel treatment using a Taylor spatial frame as part of a staged reconstruction to regain length of the extensor mechanism and maintain knee motion prior to performing primary repair of the avulsed patellar sleeve fragment.

Background: Ethyl chloride topical anesthetic spray is labeled as nonsterile, yet it is widely used during injection procedures performed in an outpatient setting. The purpose of this study was to investigate the sterility of ethyl chloride topical anesthetic spray applied before an injection. Our a priori hypothesis was that application of the spray after the skin has been prepared would not alter the sterility of the injection site.

Ankle injuries are common in the general and athletic populations. These injuries constitute 21% of all sports-related injuries. The wide spectrum of sports-related ankle injuries includes ligamentous injuries, soft-tissue and osseous impingement, osteochondral lesions of the talus, tendon injuries, and fractures.

Unlabelled: Feet are prone to bacterial contamination. We hypothesized that chlorhexidine scrub and isopropyl alcohol paint provide superior local flora reduction than povidone-iodine scrub and paint. Patients with intact, uninfected skin having clean elective foot and ankle surgery were prospectively enrolled and randomly assigned to skin preparation with povidone-iodine (Group 1) or chlorhexidine scrub and isopropyl alcohol paint (Group 2).

Background: Appropriate suture selection is necessary in providing mechanical stability to soft tissue reconstructions. Caprolactone/glycolide (Panacryltrade mark) became a popular suture, possessing excellent handling properties; however, clinical observations questioned the knot security of caprolactone/glycolide. Caprolactone/glycolide is still available on many commercial suture anchor systems.

We retrieved a high-molecular-weight poly-L-lactic) (PLLA) anterior cruciate ligament (ACL) interference screw (Arthrex, Naples, FL) after 30 months in vivo during revision ACL surgery. Gross, histologic, histomorphometric, and molecular weight measurements were carried out on the implant and the surrounding bone. These studies showed a 75% decrease in the molecular weight of the screw, with implant fragmentation and new bone formation adjacent to the screw and graft.
