    Rare Presentation of Midbrain Infarction: Isolated Medial Rectus Palsy
    (2015) Derle, Eda; Ocal, Ruhsen; Kibaroglu, Seda; Can, Ufuk; 0000-0001-8689-417X; 0000-0002-3964-268X; 0000-0003-2122-1016; 26183888; AAJ-2999-2021; AAJ-2956-2021; AAI-8830-2021; V-3553-2017
    A 69-year-old woman presented with sudden onset of diplopia. In neurologic examination left medial rectus palsy without abduction nystagmus was detected. Brain magnetic resonance imaging revealed acute ischemic lesion in mesencephalon on diffusion-weighted images. Sponteneous resolution was observed after 1 month. Medial rectus palsy is a rare presention of acute ischemic stroke and early neuroimaging is important to establish such lesions. (C) 2015 S. Karger AG, Basel

    Gastrostomy in Hospitalized Patients with Acute Stroke: "NoroTek" Turkey Point Prevalence Study Subgroup Analysis
    (2022) Arlier, Zulfikar; Can, Ufuk
    Objective: Nutritional status assessment, dysphagia evaluation and enteral feeding decision are important determinants of prognosis in acute neurovascular diseases. Materials and Methods: NoroTek is a point prevalence study conducted with the participation of 87 hospitals spread across all health sub regions of Turkey conducted on 10-May-2018 (World Stroke Awareness Day). A total of 972 hospitalized neurovascular patients [female: 53%, age: 69 +/- 14; acute ischemic stroke in 845; intracerebral hematoma (ICH) in 119 and post-resuscitation encephalopathy (PRE) in 8] with complete data were included in this sub-study. Results: Gastrostomy was inserted in 10.7% of the patients with ischemic stroke, 10.1% of the patients with ICH and in 50% of the patients with PRE. Independent predictors of percutaneous endoscopic gastrostomy (PEG) administration were The National Institutes of Health Stroke Scale score at admission [exp (ss): 1.09 95% confidence interval (CI): 1.05-1.14, per point] in ischemic stroke; and mechanical ventilation in ischemic [exp (ss): 6.18 (95% CI: 3.16-12.09)] and hemorrhagic strokes [exp (ss): 26.48 (95% CI: 1.36-515.8)]. PEG was found to be a significant negative indicator of favorable (modified Rankin's scale score 0-2) functional outcome [exp (ss): 0.032 (95% CI: 0.004-0.251)] but not of in-hospital mortality [exp (ss): 1.731 (95% CI: 0.785-3.829)]. Nutritional and swallowing assessments were performed in approximately two-thirds of patients. Of the nutritional assessments 69% and 76% of dysphagia assessments were completed within the first 2 days. Tube feeding was performed in 39% of the patients. In 83.5% of them, tube was inserted in the first 2 days; 28% of the patients with feeding tube had PEG later. Conclusion: The NoroTek study provided the first reliable and large-scale data on key quality metrics of nutrition practice in acute stroke in Turkey. In terms of being economical and accurate it makes sense to use the point prevalence method.

    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-5802-2020
    Objectives: 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.
