Publication Investigation of Brain Impairment Using Diffusion-Weighted and Diffusion Tensor Magnetic Resonance Imaging in Experienced Healthy Divers.(2018-11-17) SEYITHANOĞLU, MEHMET HAKAN; ABDALLAH, ANAS ABDELRAHIM SA; Dündar, TOLGA TURAN; KITIŞ, SERKAN; ARALAŞMAK, AYŞE; Gündağ, Papaker; SASANI, H; SEYİTHANOĞLU, MEHMET HAKAN; ABDALLAH, ANAS ABDELRAHıM SA; DÜNDAR, TOLGA TURAN; KİTİŞ, SERKAN; ARALAŞMAK, AYŞE; GUNDAG, MELİHABackground: The aim of this study was to understand the changes of decompression illness in healthy divers by comparing diffusion-weighted (DWI) and diffusion tensor MRI findings among healthy professional divers and healthy non-divers with no history of diving. 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 Evaluating the p-STAT3 and PHH-3 Expressions in WHO Grade I Benign Meningiomas(2018-01-25) HATİBOĞLU, MUSTAFA AZİZ; ABDALLAH, ANAS ABDELRAHIM SA; TOSUNER, ZEYNEP; Akdağ, Halil; ÖZEK, ERDİNÇ; DÜNDAR, TOLGA TURAN; KİTİŞ, SERKAN; GUNDAG, MELİHA; SEYİTHANOĞLU, MEHMET HAKAN; TEKİN, ABDURRAHİM; HATİBOĞLU, MUSTAFA AZİZ; ABDALLAH, ANAS ABDELRAHıM SA; TOSUNER, ZEYNEP; ÖZEK, ERDİNÇ; DÜNDAR, TOLGA TURAN; KİTİŞ, SERKAN; GUNDAG, MELİHA; SEYİTHANOĞLU, MEHMET HAKAN; TEKİN, ABDURRAHIMPublication Surgical treatment of preschool childhood spinal thoracic tuberculosis: two case reports and technical note(2018-03-01) Erdem, Mehmet Nuri; ABDALLAH, ANAS ABDELRAHIM SA; Karaca, Sinan; Aydoğan, Mehmet; ABDALLAH, ANAS ABDELRAHıM SAPublication Demographic Distribution and the Factors Affected Prognosis of Patients Who Diagnosis as Cerebral Aneurysm in a Single Center: Retrospective Evaluation of 398 Patients(2017-08-25) Asiltürk, Murad; ABDALLAH, ANAS ABDELRAHIM SA; Emel, Erhan; Güler Abdallah, Betül; ABDALLAH, ANAS ABDELRAHıM SAPublication Management of Tethered Cord Syndrome in Adults: Experience of 23 Cases(2017-03-01T00:00:00Z) SOFUOGLU, Ozden Erhan; Abdallah, ANAS ABDELRAHIM SA; EMEL, Erhan; OFLUOGLU, Ali Ender; GUNES, Muslum; GULER, Betul; ABDALLAH, ANAS ABDELRAHıM SAAIM: Tethered cord syndrome (TCS) is rarely diagnosed in adults. It is a complex clinicopathological entity that remains poorly understood. In this study, clinical outcomes of 23 consecutive congenital TCSs diagnosed in adults have been evaluated to establish a standard approach to treat congenital TCS diagnosed in adults.Publication Non-traumatic myositis ossificans in the lumbar spine.(2014-10-01T00:00:00Z) Abdallah, ANAS ABDELRAHIM SA; GOKCEDAG, A; OFLUOGLU, AE; EMEL, E; ABDALLAH, ANAS ABDELRAHıM SAPublication The Histopathological Comparison of Small- and Big-Sized Meningiomas: A Single Center Study(2017-08-25) ABDALLAH, ANAS ABDELRAHIM SA; ÖZEK, ERDİNÇ; Akdağ, Halil; SEYİTHANOĞLU, MEHMET HAKAN; KİTİŞ, SERKAN; TEKİN, ABDURRAHİM; DÜNDAR, TOLGA TURAN; GUNDAG, MELİHA; HATİBOĞLU, MUSTAFA AZİZ; ABDALLAH, ANAS ABDELRAHıM SA; ÖZEK, ERDİNÇ; SEYİTHANOĞLU, MEHMET HAKAN; KİTİŞ, SERKAN; TEKİN, ABDURRAHIM; DÜNDAR, TOLGA TURAN; GUNDAG, MELİHA; HATİBOĞLU, MUSTAFA AZİZPublication Long-term Surgical Outcomes of Spinal Schwannomas: Retrospective Analysis of 49 Consecutive Cases.(2017-01-01T00:00:00Z) EMEL, E; Abdallah, ANAS ABDELRAHIM SA; SOFUOGLU, OE; OFLUOGLU, AE; GUNES, M; GULER, B; BILGIC, B; ABDALLAH, ANAS ABDELRAHıM SAPublication Clinical outcomes of multiple aneurysms microsurgical clipping: Evaluation of 90 patients.(2018-01-01) ASILTÜRK, M; Abdallah, ANAS ABDELRAHIM SA; ABDALLAH, ANAS ABDELRAHıM SAPublication Investigation of the Factors Affecting Reherniation of LDHs according to Their MRI and Radiographs’ Findings: A Prospective Study(2017-08-25) ABDALLAH, ANAS ABDELRAHIM SA; Emel, Erhan; ABDALLAH, ANAS ABDELRAHıM SA
