Introduction: Normal brain development and function depend on the active transport of folates across the blood-brain barrier. The folate receptor-1 (FR1) protein is localized at the basolateral surface of the choroid plexus, which is characterized by a high binding affinity for circulating 5-methyltetrahydrofolate (5- MTHF). Patients and Methods: We report on the clinical and metabolic findings among five children with normal neurodevelopmental progress during the first four to six months followed by the acquisition of a neurological condition which includes marked irritability, decelerating head growth, psychomotor retardation, cerebellar ataxia, dyskinesias (choreoathetosis, ballism), pyramidal signs in the lower limbs and occasional seizures. After the age of six years the two oldest patients also manifested a central visual disorder. Known disorders have been ruled out by extensive investigations. Cerebrospinal fluid (CSF) analysis included determination of biogenic monoamines, pterins and 5-MTHF. Results: Despite normal folate levels in serum and red blood cells with normal homocysteine, analysis of CSF revealed a decline towards very low values for 5-methyltetrahydrofolate (5-MTHF), which suggested disturbed transport of folates across the blood-brain barrier. Genetic analysis of the FR1 gene revealed normal coding sequences. Oral treatment with doses of the stable compound folinic acid (0.5-1 mg/kg/day Leucovorin®) resulted in clinical amelioration and normalization of 5-MTHF values in CSF. Conclusion: Our findings identified a new condition manifesting after the age of 6 months which was accompanied by low 5-MTHF in cerebrospinal fluid and responded to oral supplements with folinic acid. However, the cause of disturbed folate transfer across the blood-brain barrier remains unknown. [less ▲]

We report the case of a 54 year old man presenting atypical chest pain. The echocardiogram showed a dilatation of the coronary sinus. Subsequently the angiographic evaluation with cardiac catheterization demonstrated a coronary artery fistula between the circumflex artery and the coronary sinus and between a megaanevrysmal right coronary artery and the coronary sinus. No significant left to right shunt was discovered, however. [less ▲]

This study examined the performance of normal controls (NC) and Alzheimer's disease (AD) patients on free recall, semantic cued recall and object cued recall of both subject-performed tasks (SPTs) and verbal descriptions of actions, by controlling familiarity of actions associated to objects. The results showed that both groups performed better after SPT encoding than after verbal encoding. in all three types of recall. In addition, this SPT advantage was greater for AD patients than for NC in the object cued recall test, emphasizing AD patients' sensibility to the congruence of cues between encoding and retrieval conditions. Following verbal encoding. NC showed a better recall for less familiar actions than for highly familiar actions, whereas AD patients exhibited the opposite pattern. These results reflect that AD patients did not benefit from a distinctiveness effect at encoding for improving subsequent retrieval of verbal information, probably due to a reduced level of elaboration during encoding. However, there was no effect of action familiarity on recall performance by both groups following SPT encoding. These results suggest that memory for verbal actions and SPTs is governed by different principles. In addition. they demonstrate the robustness of the SPT effect in AD patients, who were able to improve memory performance in the SPT condition not only with highly familiar actions but also with less familiar actions.

Background: Th2 cytokine production from airway cells is thought to govern the eosinophilic airways in ammation in allergic asthma. Induced sputum has become a widely used technique to assess airways in ammation. Methods: By applying the technique of induced sputum to collect airways cells, we have assessed the spontaneous production of a set of cytokines, including interleukin-4, 6, 10, interferon-gamma and tumour necrosis factor-alpha 6 h after a bronchial allergenic hallenge with Dermatophagoides pteronyssinus (Dpt) in 12 sensitized asthmatics and compared the results obtained after inhalation of saline as control. A group of eight healthy non-allergic subjects was enrolled to control for any non-specific effect of Dpt. Cytokines were measured by a dynamic immunoassay during a 24-h sputum cell culture. Results: Allergen challenge in sensitized asthmatics caused an acute and a late bronchospasm together with a rise in sputum eosinophil counts. Afterwards allergen sputum cells from allergic asthmatics displayed a rise in their production of IL-4 (P < 0.01), IL-6 (P < 0.05) and IL- 10 (P < 0.05) when compared to saline. By this time sputum generation of IL- 4 in atopic asthmatics was greater than in healthy subjects (P < 0.001). Furthermore, in allergic asthmatics there was a strong correlation between the rise in interleukin-4 production from sputum cells and the rise in sputum eosinophils (r = 0.87, P < 0.001). Conclusions: Sputum cell culture is a useful model to assess cytokine production in allergic asthmatics who show a marked up-regulation of Th2 cytokines following acute allergen exposure. The rise in sputum eosinophil count following allergen challenge strongly correlates with the rise in IL-4 generation from sputum cells. [less ▲]

OBJECTIVES: As repetitive transcranial magnetic stimulation (rTMS) is often applied on different days, it is of interest to know whether motor (MT) and phosphene (PT) thresholds are reproducible across time and whether the intensity determined on the first day can be used in subsequent sessions. METHODS: We studied MT and PT over 5 separate recordings in 10 healthy volunteers using a focal coil and a Magstim(Rapid stimulator. After the initial recording (session 1), the others (2 to 5) were performed respectively after 1 day, 7 days, 1 month and 4 months. RESULTS: Mean MT at rest were 65.30 +/- 5.54%, 65.7 +/- 7.18%, 60.4 +/- 4.27%, 61.8 +/- 4.34%, and 63 +/- 9.1% at sessions 1 to 5. Mean PT were 71.43 +/- 6.68%, 66.29 +/- 10.67%, 60.71 +/- 8.64%, 60.57 +/- 8.08%, and 68.71 +/- 15.48% at sessions 1 to 5. MT and PT were reproducible (ANOVA analysis), however, as shown by coefficients of variation, variability between the first 3 sessions exceeded 10% for MT in 3 subjects and in 4 subjects for PT. CONCLUSIONS: It seems preferable to determine thresholds and adapt output intensity of the stimulator at each rTMS session. [less ▲]

Tiredness is a common complaint which may have multiple causes, sometimes difficult to ascertain. As occupational activities can play a major role in the incidence of various diseases, failure to investigate the patient's work history may hinder an adequate patient care. In the clinical case described hereafter, the patient symptoms could eventually be ascribed to a psycho-organic syndrome (POS) caused by the chronic exposure to organic solvents in the painting material used. This syndrome is non specific, evolves with time in an insidious manner, and, in its last stages, may cause non reversible brain damages. When facing non typical neurological symptoms in a working age adult, one has thus to consider the possibility of this diagnosis since the workers populations exposed to solvents are large in several occupations, and because the recent legal recognition in Belgium of this syndrome as an occupational disease does provide some interesting means for a better follow-up and protection of the patients concerned.

Positron emission tomography (PET) techniques represent a useful tool to better understand the residual brain function in vegetative state patients. It has been shown that overall cerebral metabolic rates for glucose are massively reduced in this condition. However, the recovery of consciousness from vegetative state is not always associated with substantial changes in global metabolism. This finding led us to hypothesize that some vegetative patients are unconscious not just because of a global loss of neuronal function, but rather due to an altered activity in some critical brain regions and to the abolished functional connections between them. We used voxel-based Statistical Parametric Mapping (SPM) approaches to characterize the functional neuroanatomy of the vegetative state. The most dysfunctional brain regions were bilateral frontal and parieto-temporal associative cortices. Despite the metabolic impairment, external stimulation still induced a significant neuronal activation (i.e., change in blood flow) in vegetative patients as shown by both auditory click stimuli and noxious somatosensory stimuli. However this activation was limited to primary cortices and dissociated from higher-order associative cortices, thought to be necessary for conscious perception. Finally, we demonstrated that vegetative patients have impaired functional connections between distant cortical areas and between the thalami and the cortex and, more importantly, that recovery of consciousness is paralleled by a restoration of this cortico-thalamo-cortical interaction.
