    Hepatic Encephalopathy and Atypical Cortical Involvement in Cranial MRI: case report
    (Aves Yayincilik, Ibrahim Kara, 2009) Celik, Yahya; Ozbek, Bahar; Balci, Kemal; Unlu, Ercuement; Utku, Ufuk
    Hepatic encephalopathy is characterized by neuropsychiatric abnormalities occurring in patients with liver dysfunction. It most commonly occurs in association with cirrhosis, portal hypertension, portal-systemic shunts and acute liver failure. Clinical features of hepatic encephalopathy varies between mild cognitive impairment to deep coma. Several neuroimaging techniques, especially magnetic resonance imaging (MRI), may eventually be useful for the diagnosis of hepatic encephalopathy. Cranial MRI may demonstrate high signal intensity in the bilateral globus pallidum on T1-weighted images. Cortical involvement due to hepatic encephalopathy is rarely reported in the literature. We presented here a case of hepatic encephalopathy with cortical and subcortical involvement.

    Herpes Zoster Ophthalmicus With Sixth Cranial Nerve Palsy: A Case Report
    (Turkish Neurological Soc, 2008) Balci, Kemal; Utku, Ufuk; Ozbek, Bahar
    Scientific background: Herpes zoster ophthalmicus represents aproximately 25% of all zoster infections. However extraocular gaze palsy in association with herpes zoster infection is extremely rare. Objective: We presented here a patient who had herpes zoster ophthalmicus with sixth cranial nerve palsy. Case: The sixty year old patient had suffered from left retroorbital pain, conjunctival congestion and rashes on the left forehead and the nose and developed ipsilateral sixth cranial nerve palsy. Result: Herpes zoster virus infection should be taken into consideration in patients with extraocular paralysis and early treatment may prevent such complications.

    Usage of Multimodal Evoked Potentials in Diagnosis of Central Nervous System Changes in Multiple Sclerosis
    (Turkish Neurological Soc, 2011) Ozbek, Bahar; Balci, Kemal; Celik, Yahya
    Objective: Evoked potentials are used in the functional assessment of sensory and motor pathways. Conflicting results have been reported in different studies about the value of evoked potentials in demyelinating diseases. Over 80% of patients with multiple sclerosis present with a relapsing-remitting form of the disease. In this study, we aimed to examine the value of each evoked potential in demonstrating the demyelinating lesions in a homogeneous group of patients with relapsing-remitting multiple sclerosis. We also aimed to examine the correlation between clinical status and evoked potential abnormalities. Patients and Methods: Twenty patients with relapsing-remitting multiple sclerosis, and 10 healthy volunteers were included in the study to evaluate the value of evoked potentials in a homogeneous group. Visual, somatosensory and motor evoked potentials (VEP, SEP, MEP) were measured and the Expanded Disability Status Scale (EDSS) scores of the patients were calculated. Results: Of 20 patients, 15 (75%) had VEP abnormality, 14 (70%) had MEP abnormality and 12 (60%) had tibial SEP abnormality. All patients had at least one abnormal evoked potential measurement. Abnormality of evoked potentials was also correlated with high EDSS scores. Conclusion: We concluded that evoked potentials, especially used in combination, are good markers to show nerve damage damage in patients with multiple sclerosis.
