Item Relationship between Helicobacter pylori infection and white matter lesions in patients with migraine(2022) Ocal, Serkan; Ocal, Ruhsen; Suna, Nuretdin; 35597897Background/aim White matter lesions (WML) are more frequently observed in migraine patients than in the average population. Associations between Helicobacter pylori (H. pylori) infection and different extraintestinal pathologies have been identified. Here, we aimed to investigate the association between H. pylori infection and WML in patients diagnosed with episodic migraine. Materials and methods A retrospective study was conducted with 526 subjects with a diagnosis of episodic migraine. Hyperintensity of WML had been previously evaluated in these patients with brain magnetic resonance imaging (MRI) examinations. Previous endoscopic gastric biopsy histopathological examination of the same patients and reports on H. pylori findings were recorded. The demographic characteristics of the patients, such as age, gender and chronic systemic diseases such as hypertension and diabetes mellitus (DM) were recorded. Statistical evaluation was made. Results Evaluation was made among 526 migraine patients who met the inclusion criteria, comprising 397 (75.5%) females and 129 (24.5%) males with a mean age of 45.57 +/- 13.46 years (range, 18-69 years). WML was detected on brain MRI in 178 (33.8%) patients who were also positive for H. pylori (p < 0.05). Subjects who are H. pylori-positive with migraine, WML were observed at a 2.5-fold higher incidence on brain MRI (odds ratio: 2.562, 95% CI 1.784-3.680). WML was found to be more significant in patients with hypertension and migraine than those without (p < 0.001). Older age was also found to be associated with WML (OR = 1.07, 95% CI: 0.01-0.04, p < 0.001). The age (p < 0.001), H. pylori (p < 0.001), hypertension (p < 0.001), and hypertension + DM (p < 0.05), had significant associations in predicting WML according to the multivariate logistic regression analysis. The presence of hypertension had a higher odds ratio value than the other variables. Conclusion It was concluded that H. pylori infection, as a chronic infection, can be considered a risk factor in developing WML in subjects with migraine.Item Detection of multiple sclerosis from photic stimulation EEG signals(2021) Karaca, Busra Kubra; Aksahin, Mehmet Feyzi; Ocal, RuhsenBackground: Multiple Sclerosis (MS) is characterized as a chronic, autoimmune and inflammatory disease of the central nervous system. Early diagnosis of MS is of great importance for the treatment and course of the disease. In addition to the many methods, cost-effective and non-invasive electroencephalogram signals may contribute to the pre-diagnosis of MS. Objectives: The aim of this paper is to classify male subjects who have MS and who are healthy control using photic stimulation electroencephalogram signals. Methods: Firstly the continuous wavelet transformation (CWT) method was applied to electroencephalogram signals under photic stimulation with 5Hz, 10Hz, 15Hz, 20Hz, and 25Hz frequencies. The sum, maximum, minimum and standard deviation values of absolute CWT coefficients, corresponding to "1-4 Hz" and "4-13 Hz" frequency ranges, were extracted in each stimulation frequency region. The ratios of these values obtained from the frequency ranges "1-4Hz" and "4-13Hz" was decided as features. Finally, various machine learning classifiers were evaluated to test the effectivity of determined features. Results: Consequently, the overall accuracy, sensitivity, specificity and positive predictive value of the proposed algorithm were 80 %, 72.7 %, 88.9 %, and 88.9 %, respectively by using the Ensemble Subspace k-NN classifier algorithm. Conclusions: The results showed how photic stimulation electroencephalogram signals can contribute to the prediagnosis of MS.Item Frequency of headache among university students and its effect on daily living activities(2021) Ocal, Ruhsen; Iyigundogdu, Ilkin; Kirnap, Nazli Gursoy; Talu, Irem; Alkislar, Defne; Aras, Dilay; Uner, Aylin; Uzunalioglu, Ece; 0000-0001-7860-040X; AAJ-2053-2021Background & Objective: Headache is a common symptom in the general population. The aim of this study was to investigate the frequency of headache among a university students population in Ankara, Turkey; and to evaluate the factors affecting the headache and the effect of headache on students' quality of life. Methods: A face-to-face questionnaire was applied to all participants in the study. In the questionnaire, demographic data, personal background and family history of the participants as well as the presence of headache were collected. The characteristic features of the headache, accompanying symptoms and medication use for the headache were evaluated. The 36-Item Short Form Survey (SF-36), Beck depression and Beck anxiety scales were administered to all participants. Results: Three hundred and sixty six university students participated in the study. Three hundred and thirty one participants (90.4%) had experienced headache at least once in their lifetime. Headache was more common in women (p 0.01). Depression was found in 135 (36.9%) students with the Beck depression scale, and anxiety was found in 236 (64.5%) students with the Beck anxiety scale. There was no relationship between depression or anxiety and the presence of headache (p 0.05). Emotional role difficulties, social function, pain and general health scores were significantly lower on SF-36 in the group with headache (p<0.05) than without headache. Conclusion: Headache adversely affects the quality of life and is a common symptom among university students, independent of depression and anxiety.Item Evaluation of Neuroimaging Findings of Central Nervous System Complications in Heart Transplant Recipients(2020) Turnaoglu, Hale; Agildere, Ahmet Muhtesem; Rahatli, Feride Kural; Donmez, FuldemYildirim; Ocal, Ruhsen; Sezer, Taner; Can, Ufuk; Sezgin, Atilla; Aslamaci, Sait; 0000-0002-2278-1827; 0000-0001-8689-417X; 0000-0003-4223-7017; 29790456; AAJ-5931-2021; AAJ-2999-2021; AAB-5802-2020Objectives: In this study, we presented neuroradiologic findings and diagnoses of neurologic complications in a series of heart transplant recipients. Materials and Methods: A retrospective review was conducted at Baskent University Hospital. We searched the hospital and radiology databases and identified 109 heart transplant recipients. Thirty-one of these recipients had neuroradiologic evaluations secondary to presentation of neurologic symptoms after heart transplant, with 18 patients evaluated with computed tomography and 22 patients evaluated with magnetic resonance imaging (overlap of imaging-defined groups occurred in 9 recipients). Computed tomography and magnetic resonance imaging studies were retrieved from the Picture Archiving and Communication System, with each type of imaging retrospectively evaluated on consensus by 2 radiologists. Results: Radiopathologic findings related to symptoms were detected in 12 of the 31 study patients. The most common abnormality was posterior reversible leuko-encephalopathy syndrome (5 patients, 4.6%). The other abnormalities were ischemic stroke (3 patients, 2.8%), hemorrhagic stroke (1 patient, 0.9%), intracranial abscess (2 patients, 1.8%), and intracranial dissemination of sinusoidal fungal infection and related hemorrhagic infarct (1 patient, 0.9%). The other 19 heart transplant recipients who underwent computed tomography and/or magnetic resonance imaging for neurologic complaints showed no neuroradiologic findings related to neurologic symptoms. Conclusions: Posterior reversible leukoencephalopathy syndrome and ischemic stroke were the most common neurologic complications in our heart transplant recipients. The other complications were hemorrhagic stroke, intracranial abscess, and intracranial dissemination of sinusoidal fungal infection. Neurologic complications are common in heart transplant recipients and should be identified promptly for early treatment. For the recognition of these complications, computed tomography should be performed for initial evaluation to rule out edema or hemorrhage. However, in the presence of serious neurologic symptoms that cannot be explained by computed tomography, magnetic resonance imaging should be indicated.Item RESTLESS LEG SYNDROME FREQUENCY IN HEALTH WORKERS(2019) Ocal, Ruhsen; Atguden, Gizem; Aycan, Cagri; Balaban, Zeynep; Senar, Seran; Yavuz, Sena; 31517455Introduction - Restless Leg Syndrome (RLS) is a disease, primarily composed of sensational symptoms, caused by the urge to move lower extremities especially at night, and characterized by undesired feelings of the legs. Decreasing of the dopaminergic effect at night is thought to be responsible from these symptoms. RLS patients suffer from low quality of sleep affecting their daily life activities even causing socio-economic loss. Although RLS is a common and treatable disease, it can not be diagnosed easily due to the variability of symptoms. Aim - The purpose of this study is to determine the frequency of RLS among health workers and to define the disease causing factors. Method - A questionnaire was applied to 174 randomly selected health workers at Baskent University Medical Faculty (KA17/285). The demographic information, history of illnesses or usage of drugs, socioeconomic status, working hours and daytime sleepiness were questioned. Included in the questionnaire were diagnostic criteria for RLS, frequency assessment scale, and survey of sleep quality. We used "the diagnostic criteria of international RLS working group" for the diagnosis, and "Pittsburgh sleep quality index survey" to determine the quality of sleep. Reliability and validity studies were performed on both tests. Results - A significant relationship between socio-economic status and RLS was found (p<0.05) as an increase of RLS frequency in parallel with decreased socio-economic status. RLS was found to be common among health workers. We suggest that health workers should be checked regularly, and they should be informed about the disease in order to raise an awareness and hence increase their quality of life.Item EFFECT OF LIVER TRANSPLANTATION ON NEUROLOGICAL MANIFESTATIONS AND BRAIN MAGNETIC RESONANCE IMAGING FINDINGS IN WILSON DISEASE(2019) Soy, Ebru H. Ayvazoglu; Ocal, Ruhsen; Benli, Sibel; Donmez, Fuldem; Agildere, Muhtesem; Ocal, Serkan; Haberal, Mehmet; 0000-0002-0993-9917; AAC-5566-2019; AAB-5802-2020Item The frequency of buccopalpebral reflex in Parkinson disease(2016) Eser, Hulya; Unal, Yasemin; Kutlu, Gulnihal; Ocal, Ruhsen; Inan, Levent Ertugrul; 27966319; V-3553-2017Background/aim: This study aimed to define the frequency of a primitive reflex, the buccopalpebral reflex (BPR), and its association with the clinical situation in patients with Parkinson disease. Materials and methods: Between May 2010 and May 2011, 222 patients, 115 with Parkinson disease and 107 patients without any sign of neurodegenerative disease, were included in the study. All included patients were examined for BPR and snout reflex and were also evaluated with the Mini Mental State Examination. All patients with Parkinson disease were classified with the Unified Parkinson's Disease Rating Scale (UPDRS) and the Hoehn and Yahr Score to determine their clinical severity. Results: Sixteen patients with Parkinson disease (13.9%) had a BPR (+) and 4 patients in the control group (3.7%) (P < 0.001). The UPDRS score, UPDRS daily life activities score, and UPDRS motor system score were all higher in the group with BPR (+). All patients with a BPR also had a positive snout reflex. Conclusion: BPR is more frequent in patients with Parkinson disease than in patients without a neurodegenerative disease.Item The clinico-radiological spectrum of Dyke-Davidoff-Masson syndrome in adults(2017) Ocal, Ruhsen; Ayas, Zeynep Ozozen; Asil, Kiyasettin; 28733757; V-3553-2017Dyke-Davidoff-Masson syndrome (DDMS) is characterized by cerebral hemiatrophy, seizure, contralateral hemiplegia/hemiparesis, and mental retardation. In this study, clinical and radiological investigations of seven patients who were diagnosed with DDMS as adult age were evaluated and discussed. Seven patients (four male, three female) were included. The mean age +/- SD of the patients was 46 +/- 21 years. Clinical presentation of six patients was epileptic seizure. One patient was presented with head trauma due to a fall. Two patients had complex partial seizures, three patients had generalized tonic-clonic seizures (GTC), and one had GTC and myoclonic seizure. Mental retardation was in five patients. A congenital cause was detected in one patient in the etiologic investigation and acquired causes in two patients. In four patients, the etiology was not identified. We observed left-hemisphere involvement in four patients and right-hemisphere involvement in three patients. Brain imaging was performed by CT only in four patients and by MRI only in three patients. All patients were diagnosed with DDMS at adulthood. Atrophy in basal ganglia was detected in five patients, and atrophy in brain stem in four patients. Calvarial thickening was observed in four patients. Three patients had hyperpneumatization in mastoid cells. Sinus hyperpneumatization, including the paranasal and frontal sinuses, was seen in six patients. DDMS can also be diagnosed in adulthood symptomatically (mild-severe) or asymptomatically in adulthood. As a result, DDMS is a syndrome with wide clinical and radiological spectra that can be variably symptomatic at different stages of life.Item Neurological Findings in Wilson's Patients at First Examination(2017) Ocal, Ruhsen; V-3553-2017Aim: Wilson's disease (WD) is a hereditary disease that causes the accumulation of copper in many organs and tissues due to impaired copper transport. WD is presented with neurological and neuropsychiatric findings. Prognosis is usually dependent on severity of liver involvement and neurological involvement. Early treatment can control brain damage and symptoms. The time of diagnosis is related to prognosis. Our aim in this study is to determine the frequency of WD neurological manifestations in our clinic and to convey our clinical experience. Methods: Patients with diagnosis of WD and complaints were examined in the neurology outpatient clinic between 2014 and 2017. Clinical and radiological images of the patients were reviewed. Results: A total of 36 patients (11 female, 25 male) were included in the study. In the neurological examination of these patients. Only tremor was found in 4 patients, tremor and dystonia in 2 patients, tremor and chorea in 2 patients, tremor and choreatetosis in 1 patient and epilepsy in 2 patients. Neurological involvement was detected in 30.5 % of 36 WD neurological follow-up patients. Tremor is the most common neurologic finding in patient with involvement of central nervous system in WD. Symptom is tremor with 81.8 % of patients with neurological symptoms. Tremor was detected in 44.4 % of patients with WD, while another 55.6 % were accompanied by another movement disorders. Conclusion: Neurological complications are common in Wilson's disease. The most common symptom seen is tremor.
