Material/Methods: A total of 26 people were recruited in this prospective study: 11 experienced divers with no history of neurological decompression disease (cohort) and 15 healthy non-divers (control). In all study subjects, we evaluated apparent diffusion coefficient (ADC) and type of diffusion tensor metric fractional anisotropy (FA) values of different brain locations (e.g., frontal and parieto-occipital white matter, hippocampus, globus pallidus, putamen, internal capsule, thalamus, cerebral peduncle, pons, cerebellum, and corpus callosum). Results: ADC values of hippocampus were high in divers but low in the control group; FA values of globus pallidus and putamen were lower in divers compared to the control group. DWI depicted possible changes due to hypoxia in different regions of the brain. Statistically significant differences in ADC values were found in hypoxia, particularly in the hippocampus (p=0.0002), while FA values in the globus pallidus and putamen were statistically significant (p=0.015 and p=0.031, respectively). We detected forgetfulness in 6 divers and deterioration in fine-motor skills in 2 divers (p=0.002 and p=0.17, respectively). All of them were examined using neuro-psychometric tests. Conclusions: Repeated hyperbaric exposure increases the risk of white matter damage in experienced healthy divers without neurological decompression illness. The hippocampus, globus pallidus, and putamen are the brain areas responsible for memory, learning, navigation, and fine-motor skills and are sensitive to repeated hyperbaric exposurePublication Nöroşirurji Cerrahi İncelikler Kraniyal(2018-01-01T00:00:00Z) Kitiş, Serkan; KİTİŞ, SERKANPublication Relationship Between Degeneration or Sagittal Balance With Modic Changes in the Cervical Spine(2021-01-27T00:00:00Z) Kitiş, SERKAN; Çevik, Serdar; Kaplan, Atilla; Yılmaz, Hakan; Katar, Salim; Cömert, Serhat; Ünsal, Ülkün; KİTİŞ, SERKANObjective: This study evaluates the relationship between degenerative and Modic changes (MCs) in the cervical spine and compares the results with the cervical sagittal balance parameters. Methods: We retrospectively reviewed 275 patients with neck pain who applied to our outpatient clinic and underwent cervical magnetic resonance imaging (MRI) and cervical anteroposterior (AP)/lateral (Lat) X-ray radiography between January 2016 and January 2018. The clinics, demographic information, and radiological findings of the patients were examined. Modic changes, disc degeneration, and facet degeneration (FD) were examined by cervical MRI, and T1 slope and Cobb angle were measured by cervical AP/Lat X-ray radiography. These results were compared to evaluate their relations with each other. Results: No relationship between the presence or absence of degenerative changes (Modic changes, facet degeneration, and disc degeneration) and sagittal balance parameters (T1 slope and Cobb angle) was found. However, when each cervical segment was examined separately, facet degeneration at the C4-C5 level and Modic changes at the C3-C4, C4-C5, and C6-C7 levels were statistically significant with the Cobb angles, and the Modic changes at the C3-C4 level and disc degeneration at the C2-C3 level were found to be significant with T1 slope values. Conclusions: Our findings indicate that MCs increased with decreased cervical curvature, increasing disc and facet degeneration, although the causal mechanisms are not clear.Publication Anevrizmatik subaraknoid kanama sonrası prognostik faktör olarak platelet volüm indeksinin değerlendirilmesi(2019-09-01) Dündar, Tolga Turan; DÜNDAR, TOLGA TURAN; KİTİŞ, SERKAN; YURTSEVER, İSMAİLPublication Nöroşirurji Cerrahi İncelikler Kraniyal(2018-01-01T00:00:00Z) Kitiş, Serkan; KİTİŞ, SERKANPublication Çocuklarda Üst Servikal Bölge ve Kraniyovertebral bileşke yaralanmaları(2015-04-01) Karagöz Güzey, Feyza; KİTİŞ, SERKAN; Çevik, Serdar; KİTİŞ, SERKANPublication NÖROFİBROMATOZİS TİP-1’Lİ BİR HASTADA EKZOFİTİK DEV HÜCRELİ GLİOBLASTOMA: OLGU SUNUMU(2017-04-02) GUNDAG, MELİHA; KİTİŞ, SERKAN; SEYİTHANOĞLU, MEHMET HAKAN; DÜNDAR, TOLGA TURAN; GUNDAG, MELİHA; KİTİŞ, SERKAN; SEYİTHANOĞLU, MEHMET HAKAN; DÜNDAR, TOLGA TURANPublication Görüntüleme Yazılımları ve Nöroşirürji Pratiğine Katkıları(2018-08-01T00:00:00Z) Abdallah, Anas; Kitiş, Serkan; KİTİŞ, SERKAN
