Aim: To evaluate the preoperative, operative, and postoperative outcomes of young and adult patients who underwent surgery for temporal lobe epilepsy related to hippocampal sclerosis (TLE-HS)., Material and Methods: This retrospective study assessed prospectively registered data collected from 2010 to 2020. Clinical, electrophysiological, pathological, and postoperative outcomes were evaluated and compared. Post-surgical seizure outcome was classified into continuous seizure freeness without aura and relapse., Results: In total, 16 young and 48 adult patients with TLE-HS were included in the analysis. The clinical, electrophysiological, pathological, and postoperative outcomes were similar between the young and adult groups. However, the seizure outcome did not significantly differ between the two groups (p=0.38). A significant proportion of patients in both groups were satisfied with the surgical outcomes., Conclusion: Surgery is extremely effective against TLE-HS in young patients, as in adults. Furthermore, the clinical, radiological, and pathological outcomes are similar between young and adult patients with TLE-HS.

Aim: To define the substantial role of the TLR4 signaling pathway in the MyD88-dependent pathway, and to evaluate the results of TLR4 activation in nucleus pulposus cells. Moreover, we aim to associate this pathway with intervertebral disc degeneration and magnetic resonance imaging (MRI) findings. Additionally, the clinical differences among patients and the effects of their drug use will be evaluated., Material and Methods: Eighty-eight adult male patients with lower back pain and sciatica underwent MRI studies, which showed degenerative changes. Disc materials were obtained intraoperatively from those who underwent surgery for lumbar disc herniation. These materials were kept in freezers at ?80°C without any delay. Then, the collected materials were examined using enzyme-linked immunosorbent assays., Results: Modic type I degeneration had the highest values of all markers, whereas Modic type III degeneration had the lowest values. These results verified that this pathway plays an active role in MD. Moreover, contrary to the current knowledge on which Modic type inflammation is more dominant, we showed that it is the Modic type I phase., Conclusion: The most intense inflammatory process was observed in Modic type 1 degeneration, and the MyD88-dependent pathway was found to play a key role. While the most intense molecular increase was detected in Modic type 1 degeneration, the lowest levels were observed in Modic type III degeneration. It has been observed that the use of nonsteroidal anti-inflammatory drugs affects the inflammatory process through the MyD88 molecule.

Aim: To elucidate the role of the TIR-domain-containing adaptor-inducing interferon-? (TRIF) dependent pathway in intervertebral disc degeneration (IVD)., Material and Methods: A total of adult male patients with low back pain (LBP) (+/- radicular pain) were further evaluated by magnetic resonance imaging (MRI) with surgical indication for microscopic lumbar disc herniation (LDH). Preoperatively, patients were classified according to Modic Changes (MC), nonsteroidal anti-inflammatory drugs (NSAIDs) use, and the presence of radicular pain in addition to the LBP., Results: The age of the 88 patients ranged from 19 to 75 years (mean: 47.3 ± 19.6 years). Twenty eight of the patients were evaluated as MC I (31.8%), 40 as MC II (45.4%), and 20 as MC III (22.7%). The majority of patients (81.8%) had radicular LBP, while 16 patients (18.1%) had only LBP. Predominantly, 55.6% of all patients were taking NSAIDs. Levels of all adaptor molecules were highest in the MC I group and lowest in the MC III group. The levels of IRF3, TICAM1, TICAM2, NF-kB p65, TRAF6, and TLR4 were significantly increased in the MC I group compared to the MC II and MC III groups. The variations of the individual adaptor molecules showed no statistically significant difference in the use of NSAIDs and radicular LBP., Conclusion: As a result of the impact assessment, the current study clearly demonstrated for the first time that the TRIFdependent signalling pathway plays a crucial role in the degeneration process in human lumbar intervertebral disc specimens.
