OBJECTIVES X-linked adrenoleukodystrophy is a genetically determined disorder that causes varying degrees of malfunction of the adrenal cortex and central nervous system. Our aim was to investigate the occurrence of known, or new, mutations in the ABCD1 gene in two unrelated patients with clinical suspicion of the adrenoleukodystrophy. METHODS Two(More)
OBJECTIVES To date, the clinical usefulness of measuring baroreflex sensitivity (BRS) to detect impairment of the autonomic nervous system in patients with diabetes mellitus (DM) type I has not been evaluated sufficiently (Mlcáková et al. 2008). The aim of the current study was the determination and statistical comparison of the mean values of BRS in our DM(More)
OBJECTIVES Obstructive sleep apnea syndrome (OSA) is associated with increased cardiovascular morbidity and mortality. Endothelial dysfunction (ED), accelerated atherosclerosis and autonomic dysfunction might be the key players responsible for development of vascular diseases in patients with OSA. In a population with suspected OSA and low burden of(More)
OBJECTIVE The relationship between epilepsy and sleep has been known for many years. Yet is still not well understood because of it's reciprocal and intrinsic influences. Epileptic manifestations during sleep may lead to fragmentation of sleep stages. On the other hand insomnia or other sleep disorders may cause sleep deprivation and increase number of(More)
There are limited data regarding glucose metabolism dysregulation in multiple sclerosis (MS). Present study investigates glucose and insulin response during oral glucose tolerance test (oGTT) in MS patients. We examined 19 MS patients and 19 age, sex and body mass index (BMI) matched healthy controls. MS patients were newly diagnosed, untreated and with low(More)
OBJECTIVE Large epidemiological studies suggest higher risk of vascular events in patients with multiple sclerosis (MS). Chronic inflammatory response and oxidative stress, key-players in a process of atherogenesis, are also suspected to play a role in pathophysiology of MS. Prospective studies elucidating risk of atherosclerosis in MS patients are(More)
Patients experiencing solitary unprovoked epileptic seizure have different risks of recurrence. The possible risk factors include in particular: structural cerebral lesion and its cause, history of febrile seizures, family history of epilepsy, the type of seizure, epileptiform EEG discharges and the problem of initiation or (or not initiation) of(More)
BACKGROUND Exposure of vascular smooth muscle cells (VSMCs) to excessive cyclic stretch such as in hypertension causes a shift in their phenotype. The focal adhesion protein zyxin can transduce such biomechanical stimuli to the nucleus of both endothelial cells and VSMCs, albeit with different thresholds and kinetics. However, there is no distinct vascular(More)
Proton magnetic resonance spectroscopy (1H MRS) is an optional diagnostic method for potential epilepsy surgery candidates. The aim of this study was to determine the credibility of 1H MRS examination in a group of patients suffering from solitary and sporadic epileptic seizures generated in temporal lobe. We recorded a 100% sensitivity of 1H MRS in a group(More)
OBJECTIVES Developmental cerebral dysplasias are frequent causes of epilepsy. The early stage of gestation, mainly the period of neural crest separation and neuroblast migration (disturbance of midline structures, heterotopias, cortical dysplasias and disturbance of the ventricular and vascular formation), may be considered as a cause of serious cerebral(More)
