Diffusion tensor tractography imaging in pediatric epilepsy - A systematic review.

Purpose: Recent years brought several experimental and clinical reports applying diffusion tensor tractography imaging (DTI) of the brain in epilepsy. This study was aimed to evaluate current evidence for adding the DTI sequence to the standard diagnostic magnetic resonance imaging (MRI) protocol in pediatric epilepsy.

Material And Methods: Rapid and qualitative systematic review (RAE, Rapid Evidence Assessment), aggregating relevant studies from the recent 7 years.

[Magnetic resonance imaging in a patient with an implantable cardioverter-defibrillator].

The number of patients with cardiac pacemakers (PM), implantable cardioverter-defibrillators (ICD) and cardiac resynchronisation therapy PM systems is increasing. The number of magnetic resonance imaging (MRI) examinations is also growing and amounts to about 60 million tests per year worldwide. The presence of an ICD is still considered to be an absolute contraindication to MRI by most experts.

The impact of MRI white matter hyperintensities on dementia in Parkinson's disease in relation to the homocysteine level and other vascular risk factors.

Background: The role of white matter hyperintensities (WMH) and homocysteine (Hcy) and other vascular risk factors in the pathogenesis of Parkinson's disease (PD) dementia (PDD) remains unclear.

Objective: The aim of the study was to assess the impact of WMH, Hcy and other biochemical and vascular risk factors on PDD.

Methods: A total of 192 patients with PD and 184 age- and sex-matched healthy controls were included.

Cerebral vasomotor reactivity and extent of white matter lesions in middle-aged men with arterial hypertension: a pilot study.

Background: Cerebrovascular reactivity (CVR) impairment and cerebral white matter lesions (WMLs) are associated in elderly or patients with overt cerebral ischemia. Such association has not been confirmed for asymptomatic middle-aged individuals with risk factors for stroke. We assessed the relationship between the CVR and the presence of WMLs in a middle-aged population-based cohort of hypertensive men.

The influence of vascular risk factors and white matter hyperintensities on the degree of cognitive impairment in Parkinson's disease.

Background And Purpose: Vascular risk factors may contribute to deterioration of cognitive functions in Alzheimer's disease and vascular (or mixed) dementia. Parkinson's disease (PD) is an age-related disorder and vascular risk factors potentially might be the main co-morbidity responsible for motor and cognitive impairment. However, only a few studies focused on this problem have been published.

[Therapeutic difficulties in soft tissue sarcoma occurring in children with neurofibromatosis type 1 - own observations].

Unlabelled: Neurofibromatosis type I (NF1) is one of the most common genetic disorders in man, predisposing to benign and malignant tumours. The most common malignancies comprise nervous system tumours, less frequently soft tissue sarcomas (STS) and leukaemia - myelodysplasia syndrome. Herein we report five cases of STS diagnosed in children affected with NF1 (3 girls and 2 boys, age: 8 months -17 years).

Cerebral blood flow changes in patients with dementia with Lewy bodies (DLB). A study of 6 cases.

Background: The aim of this study was to show the application of cerebral blood flow SPECT (rCBF SPECT) study in dementia with Lewy bodies (DLB).

Material And Methods: (99m)Tc-ECD regional cerebral blood flow SPECT scanning was performed using a triple head, high resolution gamma camera on a group of six patients who ful- -filled criteria for clinical diagnosis of DLB. All patients were examined neurologically by a neurologist specialized in movement disorders.

Regional cerebral blood flow in Parkinson's disease as an indicator of cognitive impairment.

Objective: To investigate the pattern of regional cerebral blood flow (rCBF) deficits in Parkinson's disease patients in relation to cognitive decline and to assess the clinical usefulness of single photon emission tomography (SPET) scanning in differentiation between Parkinson's disease patients with dementia and those without cognitive deficits.

Methods: We performed Tc-ECD SPET in 60 patients with idiopathic Parkinson's disease (F: 25, M: 35), with average age of 68.4 years (SD+/-7.

[The influence of vascular risk factors and white matter hyperintensities on the degree of motor impairment in Parkinson's disease].

Background And Purpose: The aim of the study was to assess the prevalence of vascular risk factors and white matter hyperintensities (WMH) in patients with Parkinson's disease (PD) and its impact on clinical features such as motor impairment.

Material And Methods: 60 patients with PD [25 women and 35 men; mean age 68.4 (51-81) years, mean duration of disease 8.

Camptocormia or Pisa syndrome in multiple system atrophy.

Although a mild stooped posture is a hallmark of parkinsonism, extreme trunk forward flexion is not common. This phenomenon was described in different etiological entities and called camptocormia. Other similar presentations called Pisa syndrome and antecollis were described mainly in extrapyramidal disorders.

[Solid tumours of the vertebral column and spinal cord in children. Reasons and consequences of diagnostic delay].

Introduction: Primary or secondary tumours of spinal cord and vertebral column have various histological structure, various degree of malignancy and various growth dynamics. Such localisation of neoplastic disease creates problems, connected with the risk of irreversible damage of neurological functions. It is essential to make a proper diagnosis very early.

[Regional cerebral blood flow single photon emission tomography (SPECT) and magnetic resonance imaging (MRI) may be useful in the diagnosis of patients with cortico-basal degeneration, progressive supranuclear palsy and multiple system atrophy].

Differential diagnosis of idiopathic Parkinson's Disease is still very difficult. Even in movement disorders centers 25% of patients with clinical diagnosis of Parkinson's disease is misdiagnosed with other neurodegenerative disorders. Clinical symptoms of so called atypical parkinsonian disorders may emerge late in the course of the disease, not at the same time and good or moderate response to levodopa at early stages may be a source of misdiagnosis.
