Do Mean Platelet Volume and Platelet Distribution Width Have An Association with White Matter Hyperintensities in Migraine Patients?
(2023) Iyigundogdu, Ilkin; Derle, Eda; 37970292
Objective: Increased prevalence of white matter hyperintensities (WMH) is reported in migraine patients; however, the pathophysiology and the progression of these lesions are not definitely clear. Mean platelet volume (MPV) and platelet distribution width (PDW) are easily obtained markers for platelet activity. The aim of this study is to evaluate the relationship between the presence of WMH and MPV and PDW in patients with migraine in order to determine the role of platelet activity in the pathophysiology of WMH.Methods: Patients who were admitted to the neurology outpatient clinics of Baskent University Hospital from January 2011 to December 2015 with migraine and between 18 and 55 years of age were evaluated retrospectively. The blood samples were taken and total blood count parameters including MPV and PDW were analyzed. Brain magnetic resonance images were evaluated.Results: Totally, 218 patients were evaluated in this study. Forty-eight (22.0%) patients had WMH in the brain magnetic resonance imaging. In patients with WMH, the median of age was higher than the patients without WMH and the difference was statistically significant (P < 0.05). There was no statistically significant difference between MPV, PDW values, and the presence of WMH.Conclusions: There are multiple theories suggested for the mechanism of WMH, but the major cause and pathophysiology are still undetermined. Our data suggested that increased platelet activity is insufficient by itself to explain the pathophysiology of WMH in migraine patients and to improve the knowledge on this issue further large longitudinal studies should be performed.

(2021) Ocal, Ruhsen; Iyigundogdu, Ilkin; Kirnap, Nazli Gursoy; Talu, Irem; Alkislar, Defne; Aras, Dilay; Uner, Aylin; Uzunalioglu, Ece; 0000-0001-7860-040X; AAJ-2053-2021
Background & 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.
Neutrophil to lymphocyte ratio, stroke severity and short term clinical outcomes in acute ischemic stroke
(2021) Iyigundogdu, Ilkin; Derle, Eda; Kibaroglu, Seda; Can, Ufuk; 0000-0001-7860-040X; 0000-0002-3964-268X; AAJ-2053-2021; AAJ-2956-2021
Background: Neutrophil to lymphocyte ratio is an easily evaluated systemic inflammation indicator. However, there are limited reports on neutrophil to lymphocyte ratio and functional outcome in ischemic stroke. In this study, we aimed to evaluate the association of neutrophil to lymphocyte ratio and stroke severity, short term functional outcomes and mortality in patients with acute ischemic stroke. Methods: The clinical data of patients who were > 18 age-old and hospitalized with acute ischemic stroke in Baskent University Hospital, Ankara, Turkey between January 2018 and May 2019 were studied retrospectively. Neutrophil to lymphocyte ratio were measured. The neutrophil to lymphocyte ratio and National Institute of Health Stroke Scale (NIHSS) score at admission, mortality during hospitalization and Modified Rankin Scale (mRS) score at discharge of the patients with acute ischemic stroke were correlated. Results: Among the acute ischemic stroke patients due to the exclusion criteria, the data of 134 patients were evaluated. Median age of the patients were 76 +/- 12.5 years and 82 patients (61.2%) were male. The median NIHSS scores of the patients at admission was 5 +/- 4.5. Mortality during the hospitalization was seen in 8 patients (6%). The median neutrophil to lymphocyte ratio value of the patients at admission were found to be 2.6 +/- 3.4. Neutrophil to lymphocyte ratio and NIHSS scores of the patients at admission, duration of the hospitalization, mRS scores at discharge and mortality during hospitalization were found to be positively correlated. Conclusion: Neutrophil to lymphocyte ratio is a simple and easily measured marker and can be used as a potential indicator for prognosis in acute ischemic stroke. However further prospective multicenter investigations are required to confirm the role of neutrophil to lymphocyte ratio for predicting the prognosis in acute ischemic stroke patients.

Aim To compare the relationship between white matter hyperintensities (WMH) on brain magnetic resonance imaging and retinal nerve fiber layer (RNFL), choroid, and ganglion cell layer (GCL) thicknesses in migraine patients and healthy subjects. We also assessed the role of cerebral hypoperfusion in the formation of these WMH lesions. Methods We enrolled 35 migraine patients without WMH, 37 migraine patients with WMH, and 37 healthy control subjects examined in the Neurology outpatient clinic of our tertiary center from May to December 2015. RFNL, choroid, and GCL thicknesses were measured by optic coherence tomography. Results There were no differences in the RFNL, choroid, or GCL thicknesses between migraine patients with and without WMH (p>0.05). Choroid layer thicknesses were significantly lower in migraine patients compared to control subjects (p<0.05), while there were no differences in RFNL and GCL thicknesses (p>0.05). Conclusions The only cerebral hypoperfusion' theory was insufficient to explain the pathophysiology of WMH lesions in migraine patients. In addition, the thinning of the choroid thicknesses in migraine patients suggests a potential causative role for cerebral hypoperfusion and decreased perfusion pressure of the choroid layer.
Spontaneous Spinal Subarachnoid Hemorrhage with Residual Arachnoid Cyst: A Case Report
(2017) Derle, Eda; Iyigundogdu, Ilkin; Yilmaz, Cem; 0000-0003-2122-1016; 0000-0001-7860-040X; 0000-0002-2353-8044; 27593750; AAI-8830-2021; AAJ-2053-2021; AAK-2948-2021
Spinal subarachnoid hemorrhage is a rare condition that usually occurs because of secondary causes and idiopathic spontaneous ones are extremely rare. We report a 56-year-old woman who presented with severe headache, neck pain and urinary retention. Magnetic resonance imaging revealed subarachnoid hemorrhage that extended from T1 to lumbar vertebrae. She was treated conservatively and symptoms were resolved within 1 month. An asymptomatic arachnoid cyst was observed on the follow-up magnetic resonance imaging after 3 months with no neurologic deterioration. She was still stable clinically and radiologically at the end of 19 months. Spinal subarachnoid hemorrhage is a surgical emergency, although in some cases a conservative approach may be useful.
