Lumbar disc herniation surgery is commonly performed today. With radiological and clinical findings; such as low back and lower limb pain which not heal with medical treatment, motor and sensorial deficit and reflex amendments are indications of surgery. In differential diagnosis of lumbar disc herniation, rare pathologies such as Leriche syndrome should be considered. This syndrome is an occlusive thrombotic lesion of proximal part of bifurcation of abdominal aorta. The characteristic symptoms include inability to maintain penile erection, fatigue of both lower limbs, intermittent bilateral claudication with ischemic pain and absent or diminished femoral pulses along with pallor or coldness of both lower extremities. This patient was operated before with diagnose of lumbar disc herniation because of overlapping of symptoms and after 40 days Leriche syndrome was diagnosed. Vascular lesions should be considered in preoperative differential diagnosis in cases with radiologically and clinically diagnosed lumbar disc herniation. Symptoms should be depend on Leriche syndrome, findings of two disease should be together.Publication Open Access 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 Metadata only 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 Metadata only can radioterapy be a new treatment for post laminectomy low back syndrome?(2018-07-01T00:00:00Z) SEYİTHANOĞLU, MEHMET HAKAN; GÜNDAĞ PAPAKER, MELİHA; DÜNDAR, TOLGA; kitiş, serkan; SEYİTHANOĞLU, MEHMET HAKAN; GUNDAG, MELİHAPublication Unknown MELATONIN THERAPEUTIC VALUE AND NEUROPROTECTION(2015-03-01) GUNDAG PAPAKER, MELİHA; SEYİTHANOĞLU, MEHMET HAKAN; GUNDAG, MELİHA; SEYİTHANOĞLU, MEHMET HAKANPublication Unknown DEV OKSİPİTAL ENSEFOLOSEL: OLGU SUNUMU(2015-04-21) Akkaya, Enes; GUNDAG, MELİHA; KİTİŞ, SERKAN; Çevik, Serdar; SEYİTHANOĞLU, MEHMET HAKAN; GUNDAG, MELİHA; KİTİŞ, SERKAN; SEYİTHANOĞLU, MEHMET HAKAN
