    (2019) Polat, Ömer; Tuncer, Cengiz; Katı, Yusuf Alper; Uckun, Ozhan Merzuk; Er, Uyğur
    AIM: To investigate the frequency of lateral epicondylitis (LE), depending on the tasks performed by neurosurgeons, and to determinewhether it can be accepted as an occupational disease depending on its frequency.MATERIAL and METHODS: All neurosurgery specialists enrolled in the Turkish Neurosurgical Society website were prospectively included. A questionnaire form was shared, and the subsequent responses were recorded. Those who provided incomplete responseswere excluded from the study. The respondents diagnosed with LE were recorded. Exclusion criteria were investigated on complaints ofpain. They were examined by an orthopedics and traumatology specialist with application of Thomsen test and necessary maneuvers.RESULTS: The study was conducted with 216 neurosurgeons. Those with more than 30 operations per month (p=0.002), those with aspecialization duration of 10–20 years and >20 years (p=0.001), and those who specialized in spinal surgery (p=0.014) had a significantlyhigher prevalence of epicondylitis. Considering the relationship between lumbar/thoracic pedicle screw insertion and epicondylitis, theepicondylitis diagnosis rate was significantly higher in physicians inserting 20–60 screws per month than those inserting <20 screws(p=0.009).CONCLUSION: LE frequently occurs in neurosurgeons who regularly perform spinal instrumentation and appears to be an occupationaldisease. However, data obtained during the current study should be combined with findings from case-control studies of neurosurgeons.

    Is IL-8 level an indicator of clinical and radiological status of traumatic brain injury?
    (2019) Polat, Ömer; Uckun, Ozhan Merzuk; Tuncer, Cengiz; Belen, Ahmet Deniz
    BACKGROUND: Since understanding the fact that traumatic brain injury includes an inflammatory process, the number of studiesof cytokines has increased. The objective of this study was to analyze and discuss the association of interleukin (IL)-8 level with theclinical and radiological status of patients with head trauma.METHODS: Patients who were admitted to our hospital due to head trauma were included in the study. Findings of clinical and laboratory examinations were analyzed. Data regarding patient age, gender, available clinical findings, Glasgow Coma Scale (GCS) score,trauma cause, brain tomography findings, and biochemical laboratory test results were recorded. The patients were divided into 3groups according to their GCS score: Group I: GCS ?13, Group II: GCS = 9–12, and Group III: GCS = 3–8.RESULTS: A total of 23 (76.7%) patients were male and 7 (23.3%) were female. Overall, 17 (56.7%) patients were admitted due to afall, 8 (26.7%) due to a traffic accident, and 5 (16.7%) due to assault. Each group comprised 10 patients. As the GCS score increased,the IL-8 level decreased. The mean IL-8 level was 1.2 pg/mL in Group I, 6.6 pg/mL in Group II, and 4.7 pg/mL in Group III; however,there was no statistically significant difference between the groups (p=0.147). Moreover, the IL-8 level was significantly greater in patients who demonstrated an abnormal tomography finding (p=0.023).CONCLUSION: IL-8 may be a beneficial indicator for monitoring the clinical and radiological status of traumatic brain injury.Nonetheless, studies of larger cohorts in which IL-8 levels are measured at all stages of brain injury and follow-up of long-term prognosis are warranted.

    Posterior Endoscope-Assisted Diskectomy Is an Effective Technique for Cervical Soft Disk Herniation
    (Thieme Medical Publ Inc, 2021) Karaoglu, Derya Gundogdu; Polat, Omer; Uckun, Ozhan Merzuk; Karadeniz, Resul; Belen, Deniz; Dalgic, Ali
    Objective To evaluate the clinicoradiologic conditions of patients with a herniated cervical disk who were treated with percutaneous endoscope-assisted cervical diskectomy. Materials and Methods The medical data of 27 patients (16 men and 11 women; mean age: 40.9 years) who were operated on with the posterior endoscope-assisted cervical diskectomy method were reviewed retrospectively. The mean follow-up was 35.1 months, and the patients were assessed with combined preoperative and postoperative visual analog scale (VAS), Prolo Functional Economic Outcome Rating scale, MacNab scale, and clinical imaging. Results The mean preoperative VAS level was 8.6 (range: 7-10), and mean Prolo score was 2.5 (range: 2-5). A postoperative assessment performed 1 week postsurgery found a mean VAS level of 2.1 (range: 0-4). At the final examination, the mean VAS level was 0.81 (range: 0-3), and the mean Prolo score was 4.5 (range: 3-5). The final MacNab scale scores were 62.9%, excellent; 25.9%, good; 7.4%, moderate; and 3.7%, poor. Conclusion Percutaneous endoscope-assisted cervical diskectomy is a suitable and effective treatment method for soft cervical disk herniation.
