    Does the Application of Topical Intrawound Vancomycin Powder Affect Deep Surgical Site Infection and the Responsible Organisms after Spinal Surgery?: A Retrospective Case Series with a Historical Control Group

    Study Design: Retrospective case series with a historical control group. Purpose: To compare the deep wound infection rates in patients undergoing spinal surgery with the application of topical intrawound vancomycin powder (TIVP) in the surgical site in addition to standard systemic prophylaxis with those in a matched historical cohort of patients for whom TIVP was not used. Overview of Literature: Surgical site infection (SSI) after spine surgery is debilitating and is responsible for a significant increase in the health care costs, hospital stay, and morbidities. Although the application of TIVP before surgical closure is a promising method for reducing the SSI rate after spine surgery, its use is controversial, and currently, research trials are focusing on identifying its safety, efficacy, and the potential patient population. Methods: A group of 88 patients who underwent posterior spinal surgery with TIVP administration (treatment group) was compared to a historical control group of 70 patients who had received only standard systemic intravenous prophylaxis (control group) for the analysis of deep SSI rate and the involved organisms. Results: The overall rate of deep SSIs was 2.5\% (4/158). All the SSIs were observed in patients who had posterior instrumentation and fusion for >= 3 levels. In the treatment group, the SSI rate was 3.4\% (3/88), and the bacteria isolated were Escherichia coli (n=2 ) and Pseudomonas aeruginosa (n=1). In the control group, the infection rate was 1.4\% (1/70), and the isolated bacteria were Morganella rnorganii and Staphylococcus epidermidis. No statistically significant association was found between the SSI rates of the treatment and control groups. Conclusions: Although the difference in the SSI rates was not statistically significant, the present results suggest that TIVP administration could not reduce the risk of deep SSIs after spinal surgery. Moreover, TIVP administration might also affect the underlying pathogens by increasing the propensity for gram-negative species.

    Complementary Specific Pelvic Sequences on Routine Lumbar Magnetic Resonance Imaging Scans: An Imaging-Based Study Focused on Piriformis Syndrome
    (TURKISH NEUROSURGICAL SOC, 2019-01-01) Ayhan, Selim; Nabiyev, Vugar Nabi; Yetisyigit, Yasin; Palaoglu, Selcuk; Yorubulut, Mehmet
    AIM: To discuss the rationale and merit of specific pelvic sequences as an adjunct to routine lumbar magnetic resonance imaging (MRI) for early detection of piriformis syndrome (PS) and to disclose its frequency in patients who underwent radiological evaluation. MATERIAL and METHODS: This retrospective, imaging-based study included all individuals who underwent lumbar MRI and those who were further evaluated with a pelvic MRI, but excluded all high-energy trauma Cases. The patients' demographics and radiological features were reviewed using electronic patient records and hospital-based picture image archiving and communication system. RESULTS: Overall, 1321 individuals (659 females
