Öğe Contralateral Subdural Effusion Secondary to Decompressive Craniectomy: Differences in Patients with Large Hemispheric Infarctions and Traumatic Brain Injury(Karger, 2010) Kilincer, Cumhur; Hamamcioglu, Mustafa Kemal[Abstract Not Available]Öğe Erdheim-Chester Disease Presented with Bilateral Carotid Artery Occlusion: Case Report(Turkish Neurological Soc, 2010) Celik, Yahya; Balci, Kemal; Asil, Talip; Tuzun, Erdem; Hamamcioglu, Mustafa Kemal; Temizoz, Osman; Albayram, SaitErdheim-Chester disease is a rare, non-Langerhans form of systemic histiocytosis of unknown etiology. The disease affects multiple organ systems, including musculoskeletal, cardiac, pulmonary, gastrointestinal, and central nervous systems, producing protean manifestations. Neurological manifestations are less frequent. We present a 44-year-old patient with Erdheim-Chester disease who had bilateral carotid artery occlusion and cavernous sinus infiltration.Öğe Intrasacral extradural arachnoid cysts - Three case reports(Japan Neurosurgical Soc, 2008) Hamamcioglu, Mustafa Kemal; Hicdonmez, Tufan; Kilincer, Cumhur; Cobanoglu, SebahattinThree patients presented with rare intrasacral extradural arachnoid cysts manifesting as sensory deficiencies and pain in the lower extremities. Magnetic resonance imaging with various sequences identified the cysts. Two patients underwent surgery via laminectomy of the sacrum for cyst exploration and disconnection of the cyst with the dural theca. Postoperative outcome was favorable in these two patients. Intrasacral extradural arachnoid cyst should be considered in the differential diagnosis of low back pain.Öğe A laboratory training model in fresh cadaveric sheep brain for microneurosurgical dissection of cranial nerves in posterior fossa(Taylor & Francis Ltd, 2008) Hamamcioglu, Mustafa Kemal; Hicdonmez, Tufan; Tiryaki, Mehmet; Cobanoglu, SebahattinA neurosurgical laboratory training model is designed for residents of neurosurgery to handle surgical microscopes and microneurosurgical instruments. The material consists of a one-year-old fresh cadaveric sheep cranium. A four-step approach was designed to simulate microneurosurgical dissection along the posterior fossa cisterns, and to dissect cranial nerves emerging from the brain stem. We conclude that this laboratory training model is useful to allow trainees to gain experience with the general use of an operating microscope, and familiarity with handling cranial nerves.Öğe Microsurgical training model for residents to approach to the orbit and the optic nerve in fresh cadaveric sheep cranium(Wolters Kluwer Medknow Publications, 2014) Altunrende, M. Emre; Hamamcioglu, Mustafa Kemal; Hicdonmez, Tufan; Akcakaya, Mehmet Osman; Birgili, Baris; Cobanoglu, SebahattinBackground: Neurosurgery and ophthalmology residents need many years to improve microsurgical skills. Laboratory training models are very important for developing surgical skills before clinical application of microsurgery. A simple simulation model is needed for residents to learn how to handle microsurgical instruments and to perform safe dissection of intracranial or intraorbital nerves, vessels, and other structures. Materials and Methods: The simulation material consists of a one-year-old fresh cadaveric sheep cranium. Two parts (Part 1 and Part 2) were designed to approach structures of the orbit. Part 1 consisted of a 2-step approach to dissect intraorbital structures, and Part 2 consisted of a 3-step approach to dissect the optic nerve intracranially. Results: The model simulates standard microsurgical techniques using a variety of approaches to structures in and around the orbit and the optic nerve. Conclusions: This laboratory training model enables trainees to gain experience with an operating microscope, microsurgical instruments and orbital structures.Öğe Negative serology: could exclude the diagnosis of brucellosis?(Springer Heidelberg, 2012) Celik, Aygul Dogan; Yulugkural, Zerrin; Kilincer, Cumhur; Hamamcioglu, Mustafa Kemal; Kuloglu, Figen; Akata, FilizTwo cases of brucellar spondylodiscitis of the lumbar area were presented. Although both cases showed typical radiological changes, serological tests could not detect Brucella agglutinating antibodies. One of the patients was bacteremic and Brucella spp. was identified from blood culture. In the second patient needle biopsy was required for definite diagnosis. Although small, serologic tests have a certain rate of false negative results in brucellosis. Thus, a negative serology should not exclude the diagnosis of brucellosis, as it is demonstrated in the current cases.Öğe Postural tremor as a manifestation of spontaneous intracranial hypotension(Elsevier Sci Ltd, 2010) Turgut, Nilda; Unlu, Ercuement; Hamamcioglu, Mustafa Kemal; Guldiken, Babuerhan; Albayram, SaitSpontaneous intracranial hypotension (SIH) is a syndrome caused by low cerebrospinal fluid (CSF) pressure due to leakage of CSF. Clinically, orthostatic headache, neck pain, nausea, emesis, interscapular pain, diplopia, dizziness, changes in hearing, visual blurring and radicular upper extremity symptoms are most frequently observed. We describe a 57-year-old man with SIH who presented with postural tremor. CSF leakage was revealed by cranial MRI. Lumbar puncture identified low CSF pressure and intrathecal gadolinium enhanced MR cisternography showed diffuse CSF leakage in the thoracolumbar region. The patient underwent epidural blood patching, which resulted in complete resolution of postural tremor within 2 months. (C) 2009 Elsevier Ltd.

The aim of this study is to predict the prognosis of isolated HI patients by simply using data from the first day after injury. Materials and Methods: Data of head injury patients in Trakya University Hospital between January 1996 and December 2006 were obtained from records. The age, gender, causes of HI, basic neurologic examination findings, radiologic findings and discharge status are examined. Results: Most of the data were simplified as absent (0) and present (1), and mortality rates for each groups were accepted weighted values. All data were processed statistically and two models were created. Model 1 with Glasgow Coma Scale (GCS) score predicted the mortality/vegetative event at a rate of 56.5%, and the conscious survival event at 98.7%. Model 2, without the GCS score, predicted the mortality/vegetative event at 55.1% rate and the conscious survival event at 99.2%. Conclusion: Both models could be used for informing the patient and relatives and helping them to understand the severity of HI in busy working conditions of emergency departments.Öğe Surgical complications of decompressive craniectomy for head trauma(Springer Wien, 2010) Kilincer, Cumhur; Hamamcioglu, Mustafa Kemal[Abstract Not Available]
