The Effect of Slime Factor in the Treatment of Spinal Implant Infections.

AIM: To investigate the effect of the biofilm-forming ability of the bacteria on treatment in rats by using biofilm-forming and nonbiofilm- forming strains of Staphylococcus aureus (S. aureus). MATERIAL AND METHODS: Forty rats were divided into four equal groups as Group 1A, 1B, 2A, and 2B. All rats underwent single distance lumbar laminectomy, and titanium implants were introduced. Group 1 rats were inoculated with Slime factor (-) S. aureus, while Group 2 rats were inoculated with biofilm Slime factor (+) S. aureus. None of the rats were given antibiotics. One week later, the surgical field was reopened and microbiological samples were taken. The implants of rats in Groups 1A and 2A were left in place, while the implants of rats in Groups 1B and 2B were removed. RESULTS: There was no statistically significant difference between the groups inoculated with slime factor (+) S. aureus; although, Groups 1A and 2A showed statistically significant difference. Statistical analysis with respect to bacterial count also showed a statistically significant difference between Groups 1A and 2A. There was a statistically significant difference between Group 1B and 2B. CONCLUSION: The results obtained in the present study reveal that in case of implant-dependent infection, the first sample taken can be checked for slime factor, and if there is infection with slime factor-negative bacterium, treatment without removing the implant may be recommended. S. aureus was used in the study because it is the most common cause of implant-related infection at surgical sites. Further studies using different bacterial species are needed to reach a definitive conclusion.

Effectiveness of ultrasonography-guided caudal epidural steroid injection compared to the fluoroscopic application.

BACKGROUND: Caudal epidural steroid injection (CESI) has been increasingly used for treating lower back pain. However, there is still significant controversy about the efficacy and safety of different imaging techniques used to guide CESI. In this context, the objective of this study is to compare the efficacies of fluoroscopy- and ultrasonography-guided CESI in patients with chronic lower back pain. METHODS: The population of this retrospective, observational study consisted of all consecutive patients who underwent CESI for lower back pain between 2018 and 2020. Of the 371 patients included in the study sample, 192 had undergone fluoroscopyguided CESI (Group F) and 179 ultrasonography-guided CESI (Group U). Patients' pain and functional statuses were evaluated using the visual analog scale (VAS) and Oswestry Disability Index (ODI) immediately before (baseline) and after the procedure (postintervention day 0-D0), during the second week (D15), the first month (D30), and the third month (D90) after the procedure. RESULTS: The mean age of Group F was significantly higher than that of Group U (p < 0.001). The number of patients with lumbar dischernia was significantly higher in Group U, whereas the number of patients with spinal stenosis and lumbar disc hernia + spinal/lumbar stenosis was significantly higher in Group F (p = 0.001). The baseline and D0 ODI scores were significantly lower in Group U than in Group F (p = 0.006 and p = 0.017, respectively). There was no significant difference between the groups in other VAS and ODI scores (p > 0.05). Intragroup analyses revealed significant reductions in VAS and ODI scores over the follow-up period till D30 compared to the baseline scores in each group (p < 0.001). The decrease recorded in the ODI score between the D15 and baseline measurements was significantly higher in Group F than in Group U (p = 0.006). DISCUSSION: The study findings indicated that ultrasound-guided CESI was as effective as fluoroscopy-guided CESI in treating chroniclower back pain.

Physical Trauma among Refugees: Comparison between Refugees and Local Population Who Were Admitted to Emergency Department-Experience of a State Hospital in Syrian Border District.

BACKGROUND: Hundreds of thousands of people have fled to Turkey since the civil war started in Syria in 2011. Refugees and local residents have been facing various challenges such as sociocultural and economic ones and access to health services. Trauma exposure is one of the most important and underestimated health problems of refugees settling in camps. AIMS: We aimed to evaluate refugee admissions to emergency department because of trauma in means of demographics of patients and mechanism of trauma and compare the results with the local population. METHODS: Retrospective evaluation of results and comparison with the results of local population. RESULTS: We determined that the ratio of emergency admission of refugee patients because of trauma was significantly higher than the local population for most types of trauma. CONCLUSION: Further studies with more refugee participants are needed to fully understand the underlying reasons for this high ratio to protect refugees as well as for planning to take caution to attenuate the burden on healthcare systems.
