Item Neurologic Complications After Pediatric Heart Transplant: A Single-Center Experience(2022) Orgun, Ali; Erdogan, Ilkay; Varan, Birgul; Sezer, Taner; Tokel, N. Kursad; Ozkan, Murat; Sezgin, Atilla; 33797352Objectives: Neurologic complications that can lead to serious mortality and morbidity in pediatric heart transplant recipients have been reported to range from 23.6% to 45%. In this study, the frequency, time, cause, and characteristics of neurologic complications in pediatric heart transplant recipients were evaluated. Materials and Methods: We retrospectively reviewed data of 37 pediatric heart transplant recipients aged <18 years who were seen at our hospital between 2007 and 2017. Medical records were reviewed to identify neurologic complications. Clinical features were compared between pediatric heart transplant patients with and without neurologic complications. Results: The rate of posttransplant neurologic complications in pediatric heart transplant was 27% (10/37). Median age of patients with neurologic complications was 12 years (range, 11-18 years). Median time for neurologic complications was 3 days (range, 2-46 days). Primary diagnoses of these 10 recipients were dilated cardiomyopathy (n = 7) and restrictive cardiomyopathy (n = 3). There were no significant differences between recipients with and without neurologic complications (P>.05). The etiologies of neurologic complications were posterior reversible encephalopathy syndrome in 3 patients (8.1%), stroke in 2 patients (5.4%), peripheral neuropathy in 2 patients (5.4%), hypertensive encephalopathy in 1 patient (2.7%), and drug encephalopathy in 1 patient (2.7%). Conclusions: Neurologic complications may lead to serious mortality and morbidity in pediatric heart transplant patients. Seizures, posterior reversible encephalopathy syndrome, stroke, peripheral neuropathy, transient ischemic attack, and cerebral infections are the most common neurologic complications, which are seen in the perioperative period in particular. Careful follow-up of pediatric heart transplant patients, with detection and early treatment of neurologic findings, will contribute to lower rates of sequelae. To our knowledge, this is the largest study to show a detailed experience of neurologic complications in pediatric heart transplant patients from a single center in Turkey.Item Computer Game Assisted Task Specific Exercises in the Treatment of Motor and Cognitive Function and Quality of Life in Stroke: A Randomized Control Study(2021) Ozen, Selin; Senlikci, Huma Boluk; Guzel, Sukran; Yemisci, Oya Umit; 0000-0001-6771-3265; 0000-0002-7290-8558; 0000-0001-9852-0917; 34293643; AAX-8965-2021; ABC-1305-2020; AAG-3148-2021Objectives: Computer game assisted task specific exercises (CGATSE) are rehabilitation gaming systems (RGS) used in stroke rehabilitation to facilitate patient performance of high intensity, task based, repetitive exercises aiming to enhance neuroplasticity. CGATSE maybe an appealing option in home based rehabilitation of stroke patients, especially during the COVID-19 pandemic. This study aimed to determine the effects of CGATSE on hemiplegic arm-hand function, cognitive function and quality of life in stroke. Materials and methods: Thirty stroke patients were randomized into two groups. All participants received twenty sessions of physical therapy. In addition, the therapy group undertook thirty minutes of CGATSE using the Rejoyce gaming system; while the control group undertook thirty minutes of occupational therapy (OT). Motor function was evaluated before and after treatment using the Fugl Meyer upper extremity (FMUE), Brunnstrom stages of stroke recovery (BSSR) arm and hand. The CGATSE group also completed the Rejoyce arm hand function test (RAHFT). Cognitive function was evaluated using the mini mental state examination, Montreal Cognitive Assessment (MoCA) and Stroke Specific Quality of Life (SS-QOL) scale. Results: The FMUE, BSSR arm and SSQOL improved in both groups (p < 0.05). BSSR of the hand improved only in the CGATSE group (p = 0.024). RAHFT scores improved in the CGATSE group (p = 0.008). MoCA scores significantly improved in the control group (p = 0.008). Conclusions: CGATSE may be beneficial in providing continuation of care after stroke, especially during the Covid-19 pandemic when home based rehabilitation options are becoming increasingly important. Benefits of CGATSE in improving cognitive function is less clear. RGS aimed at improving motor function may be compared to gaming systems designed to target cognitive development and more detailed higher cortical function deficit tests can be used as outcome measures.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 The sensitivity and specificity of the balance evaluation systems test-BESTest in determining risk of fall in stroke patients(2019) Sahin, Ilknur Ezgi; Guclu-Gunduz, Arzu; Yazici, Gokhan; Ozkul, Cagla; Volkan-Yazici, Melek; Nazliel, Bijen; Tekindal, Mustafa Agah; 0000-0002-4060-7048; 30814369BACKGROUND: Balance disorders cause disability in stroke and increase risk of falls. The Balance Evaluation Systems Test (BESTest), examines balance, determines parameters causing balance disorders, provides information on risk factors for falls. OBJECTIVE: To investigate the sensitivity and specificity of the BESTest in determining the risk of fall in stroke patients. METHODS: Fifty patients with chronic stroke were included in the study. Balance was assessed using BESTest, Berg Balance Scale (BBS), Activity Specific Balance Confidence scale (ABC) and Biodex-BioSway Balance System. To examine the content validity of BESTest, the relationship between BESTest and other balance assessment methods was examined. The internal consistency reliability of BESTest was evaluated by Cronbach's alpha coefficient. Analysis of receiver operating characteristics (ROC) was performed to determine cut-off point, sensitivity and specificity. RESULTS: BESTest, BBS, ABC and Biodex-BioSway Balance System results of faller stroke patients were worse than that of non-faller (p < 0.05). Internal consistency of BESTest was found to be Cronbach's alpha = 0.960. The BESTest value of area under the curve (AUC) was 0.844, with a cut-off point of 69.44%, a sensitivity of 75% and a specificity of 84.6% (p < 0.01). CONCLUSION: BESTest is reliable and valid with high sensitivity and specificity in determining the risk of fall in stroke patients.
