Cím:Effect of reading with direct or indirect light on the visually evoked flow response in the posterior cerebral artery / Eszter Balogh, Tamás Árokszállási, László Csiba, László Oláh
Dátum:2019
ISSN:0091-2751
Megjegyzések:Purpose: Reading with direct light from computer monitors or tablets may cause visual fatigue and hamper reading comprehension. Our aim was to compare the blood flow response in the supplying artery of the visual cortex when reading from tablet screen or from paper. The neurovascular coupling was tested also after 15-minute reading from either monitor or paper. Methods: Flow velocity responses evoked by reading from paper and from monitor were measured by transcranial Doppler sonography in a random sequence in both posterior cerebral arteries (PCAs) of 20 young healthy adults. Afterward, PCA flow response evoked by reading from paper was also investigated after 15 minutes reading on the same tablet or paper, in a random order. Results: Reading from monitor with its own source of light and reading from paper with indirect light caused very similar PCA flow response. Moreover, the flow velocity increase, evoked by reading form paper did not differ after 15-minute reading from monitor or from paper. Conclusions: Reading with direct or indirect light produces similar flow response in the occipital cortex.

Cím:Role of hyperlipidemia in atherosclerotic plaque formation in the internal carotid artery / Kerenyi, L., Mihalka, L., Csiba, L., Bacso, H., Bereczki, D.
Dátum:2006
ISSN:0091-2751
Megjegyzések:The role of hyperlipidemia in atherosclerotic changes of the carotid artery is controversial. The aims of this retrospective study were to assess (1) the relationship between total serum cholesterol and triglyceride and the grade of internal carotid artery stenosis and (2) whether total serum cholesterol and triglyceride levels are independent risk factors for internal carotid artery atherosclerosis. METHODS: The files of 1,934 acute ischemic stroke patients were investigated retrospectively. The atherosclerotic involvement of the internal carotid artery was assessed via duplex sonography as percent of stenosis and was graded as follows: group 1, no plaque; group 2, <30% stenosis; group 3, 30-99% stenosis; and group 4, occlusion. RESULTS: The mean age of the patients was 66.9 +/- 12.8 years. Patients without any plaque had significantly lower cholesterol levels compared with those with any degree of internal carotid artery stenosis. Univariate analysis revealed that age (p < 0.001), sex (p < 0.001), hypertension (p < 0.05), cholesterol (p < 0.01), triglycerides(p < 0.05), and smoking (p < 0.001) were significant contributors to atherosclerosis. In the ordinal logistic regression model, age (p < 0.001), sex (p < 0.001), smoking(p < 0.001), and cholesterol (p < 0.05) remained independent predictors of internal carotid artery atherosclerosis. CONCLUSIONS: Total serum cholesterol level seems to be an independent risk factor of atherosclerosis in the carotid artery.

Cím:Cerebrovascular reserve capacity in patients with hyperlipidemia / Levente L. Kerenyi, Bela Fulesdi, Andrea Ficzere, Zoltan Kaposzta, Attila Valikovics, Gyorgy Paragh, Laszlo Csiba
Dátum:2000
Megjegyzések:Because recent data are conflicting, it is not certain whether hyperlipidemia is an independent risk factor for cerebrovascular diseases. Decreased cerebrovascular reserve capacity refers to the decreased ability of the cerebral arterioles to adapt in critical conditions and probably predicts a higher risk of stroke. The aim of this study was to compare cerebrovascular reserve capacity in hyperlipidemic patients and healthy controls using transcranial Doppler sonography. METHODS: Thirty-four hyperlipidemic patients and 21 healthy controls were examined. With transcranial Doppler sonography, the mean blood flow velocity in the middle cerebral artery was registered at rest and at 5, 10, 15, and 20 minutes after intravenous administration of 1,000 mg acetazolamide. Cerebrovascular reactivity and reserve capacity were calculated from mean blood flow velocities. Various laboratory measurements were also made and assessed for correlation with resting cerebral blood flow velocity and cerebrovascular reserve capacity. RESULTS: No significant differences could be observed between controls and hyperlipidemic patients in cerebrovascular reactivity or cerebrovascular reserve capacity. No correlation was found between various laboratory measurements and resting cerebral blood flow velocity or cerebrovascular reserve capacity. CONCLUSIONS: We could not demonstrate any differences in cerebrovascular reserve capacity between hyperlipidemic patients and healthy controls. Thus, the vasodilatory ability of the cerebral arterioles seems to remain unchanged in this patient group and is not correlated with the severity of hyperlipidemia.

Cím:Computed tomographic and transcranial Doppler sonographic findings in acute and subacute phases of middle cerebral artery strokes / Leanyvari, Z., Vastagh, I., Fulesdi, B., Szirmai, I., Lengyel, A., Csiba, L., Bereczki, D.
Dátum:2002
ISSN:0091-2751
Megjegyzések:The aim of this study was to compare the sensitivities of visual and densitometric analyses of CT scans and transcranial Doppler sonograms (TCD) in detecting early changes in acute stroke. METHODS: CT and TCD were each performed twice in 12 patients; first in the acute phase (within 28 hours of stroke onset), then in the subacute phase (mean +/- standard deviation, 6 +/- 3 days after onset) of a stroke. Hypodensity on the CT scans was evaluated visually, and the optical density of both the stroke region and the corresponding region on the unaffected side was measured. Measurement of flow parameters in the middle cerebral artery was carried out with TCD before or shortly (within 4 hours) after CT scanning. RESULTS: In the acute phase, blood flow velocities were significantly lower on the affected side than they were on the unaffected side (means, 42 +/- 13 and 55 +/- 25 cm/second, respectively; p = 0.012). Marked asymmetry in flow velocity was found in 3 of the 4 patients who had normal CT scans in the acute phase. The asymmetry in flow velocity disappeared by the sixth day after the stroke. The resistance index did not correlate with the final infarct size. CONCLUSIONS: In some patients, the use of TCD in acute stroke may show alterations that reflect tissue damage that is undetectable on CT. Therefore, CT and TCD should be considered complementary diagnostic tools in the acute phase of stroke.

Cím:Angiotensin-converting enzyme gene polymorphism, carotid intima-media thickness, and left ventricular mass index in adolescent hypertension / Dénes Páll, Georgios Settakis, Éva Katona, János Zatik, József Kollár, Martien Limburg, Béla Fülesdi
Dátum:2004
Megjegyzések:The aim of this study was to determine whether a positive correlation exists between the DD genotype of angiotensin-converting enzyme (ACE) and the carotid intima-media thickness (IMT) or left ventricular mass index (LVMI) in adolescents with hypertension. METHODS: We studied 120 hypertensive and 58 normotensive (control) adolescents. ACE gene polymorphism was determined by a standardized method. The IMT was measured in the common carotid arteries, and the LVMI was calculated on transthoracic echocardiography. The severity of hypertension was graded according to the results of ambulatory blood pressure monitoring as white coat, borderline, or proven hypertension. The association between ACE gene polymorphism and the obtained parameters was analyzed using analysis of variance and chi-square testing. RESULTS: Both the IMT and LVMI were higher in hypertensive than in control adolescents. In hypertensive subjects, no relationship was found between the different ACE genotypes and the IMT: the mean (+/- standard deviation) IMT in patients with the DD genotype was 0.57 +/- 0.11 mm; in those with the DI genotype, 0.53 +/- 0.01 mm; and in those with the II genotype, 0.55 +/- 0.01 mm. The LVMI was also similar in all 3 ACE genotypes: DD, 106.7 +/- 32.3 g/m(2); DI, 102.2 +/- 38.1 g/m(2); and II, 103.2 +/- 26.3 g/m(2). The severity of hypertension as assessed by ambulatory blood pressure monitoring was independent of the ACE genotype. CONCLUSIONS: Target-organ damage (left ventricular hypertrophy and carotid atherosclerosis) is detectable in adolescents with hypertension and, in those subjects, ACE genotype polymorphism is not correlated with the severity of target-organ damage as measured by IMT and LVMI.
