    [Purpose] This study was conducted to examine the association between Modic classification and the eating habits in patients with degenerative disc disease (DDD) and to determine the influence of nutrition on disease severity. [Subjects and Methods] Sixty patients with DDD visiting a low back pain outpatient clinic were enrolled. Through face-to-face interviews, they completed questionnaires regarding their demographics, disease activity, smoking and alcohol use, concomitant diseases, disease duration, and nutritional status. Exclusion criteria were age 65 years, other comorbidities, missing MRI data, and inability to speak Turkish. [Results] Forty patients were finally included in the study. The frequency with which they consumed water, salt, fast food, eggs, milk, yogurt, cheese, whole wheat bread, white bread, butter, and margarine was recorded. A weak negative correlation was observed between the Modic types and fish and egg consumption. [Conclusion] Modic changes, which indicate the severity of DDD, seem to be correlated to patients- dietary habits. However, studies with comparison groups and larger samples are needed to confirm our promising results before any cause-and-effect relationship can be proposed.

    A Rare Cause of Headache in the Emergency Department: Intraventricular Epidermoid Cyst Rupture With Hydrocephalus.
    (2016-07-01) YIGIT, M; Seyithanoglu, MEHMET HAKAN; DUNDAR, TOLGA TURAN; SOGUT, O; YIGIT, E; SEYİTHANOĞLU, MEHMET HAKAN; DÜNDAR, TOLGA TURAN
    Lateral intraventricular tumors are not frequently observed. Since these tumors grow linearly rather than exponentially, they grow gradually and thus do not cause mass effects and hydrocephalus. This study is the case report of a rare great volume left intraventricular epidermoid cyst rupture. The tumor was found to be associated with mass effect on neighboring structures and hydrocephalus.

    Leriche Syndrome With Lumbar Disc Hernia: First Case Report in Literature
    (2011-01-01) Seyithanoglu, MEHMET HAKAN; Gundag, MELİHA; DOGAN, Kazim; Kitis, SERKAN; Aydin, TEOMAN; PERU, Celalettin; SEYİTHANOĞLU, MEHMET HAKAN; GUNDAG, MELİHA; KİTİŞ, SERKAN; AYDIN, TEOMAN
    Leriche syndrome and lumbar disc herniation have typical clinical findings of their own, although similar findings can form in the lower extremities. 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.

    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, MELİHA
    Background: 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 exposure

    Diffuse Idiopathic Skeletal Hyperostosis Interfering with Ankylosing Spondylitis: A Case Report
    (2014-03-01T00:00:00Z) Taspinar, Ozgur; Aydin, Teoman; Kepekci, Muge; Peru, Celaleddin; Seyithanoglu, Hakan; AYDIN, TEOMAN; SEYİTHANOĞLU, MEHMET HAKAN
    Ankylosing spondylitis is the axial skeleton and sacroiliac crick, starting in late adolescence or early adulthood age, and is characterized by spondyloarthropathy. Some symptoms are confused with diffuse idiopathic skeletal hyperostosis. Our case had neck, back, waist, and heel pain and morning stiffness lasting about half an hour and was admitted with complaints. Lateral lumbar spine radiographs taken at the corners of the lumbar vertebral bodies compatible with DISH consecutive osteophytes were detected, and radiography of the calcaneus of the lateral foot showed hyperostosis compatible with DISH. However, the patient was diagnosed with ankylosing spondylitis because of a bilateral crick in the sacroiliac radiography. In this case-a differential diagnosis between DISH and ankylosing spondylitis-clinical and radiological features were assessed by reviewing the literature.
