Background: Safinamide modulates both dopaminergic and glutamatergic systems with positive effects on motor and non-motor symptoms of Parkinson's disease (PD). The drug utilization study SYNAPSES was designed to investigate the use of safinamide in routine clinical practice, as recommended by the European Medicines Agency. Objective: To describe the occurrence of adverse events in PD patients treated with safinamide in real-life conditions. Methods: The SYNAPSES trial is an observational, European, multicenter, retrospective-prospective cohort study. Patients were followed up to 12 months with analyses performed in the overall population and in patients aged >75 years, with relevant comorbidities and with psychiatric conditions. Results: Of the 1610 patients included, 82.4% were evaluable after 12 months with 25.1% of patients >75 years, 70.8% with relevant comorbidities and 42.4% with psychiatric conditions. During observation 45.8% patients experienced adverse events, 27.7% patients had adverse drug reactions and 9.2% patients had serious adverse events. The adverse events were those already described in the patients' information leaflet. The majority were mild or moderate and completely resolved and no differences were detected between the subgroup of patients. Clinically significant improvements were seen in the UPDRS motor score and in the UPDRS total score in >= 40% of patients, according to the criteria developed by Shulman et al. Conclusion: The SYNAPSES study confirms the good safety profile of safinamide even in special groups of patients. Motor complications and motor scores improved with clinically significant results in the UPDRS scale maintained in the long-term.

Gliomas are regionally heterogeneous tumors. The local relationship between histologic features and radiotracer uptake evaluated by PET should therefore influence analysis and interpretation of PET results on gliomas. This study explored this local relationship as a result of PET guidance of stereotactic biopsies.Local histology was confronted to the regional uptake of 18F-2-fluoro-2-deoxy-D-glucose (18F-FDG) and 11C-methionine (11C-MET) in 14 patients with high-grade glioma diagnosed during a procedure of PET-guided stereotactic biopsies. We analyzed the uptake of both tracers in regions of interest centered on the stereotactic coordinates of 93 biopsy samples.A semiquantitative analysis revealed a significant regional correlation between 11C-MET and 18F-FDG uptakes. Uptake of both tracers was significantly higher on the site of tumor samples showing anaplastic changes than in the rest of the tumor. Presence of necrosis in anaplastic areas of the tumor significantly reduced the uptake of 11C-MET.PET with 11C-MET and 18F-FDG may help to evaluate, in vivo, the metabolic heterogeneity of human gliomas. Anaplasia is a factor of increased uptake of both tracers, but microscopic necrosis in anaplastic areas influences their uptake differently. This finding probably relates to the differences in tracer uptake by non-neoplastic components of necrotic tumors. These results underline the complementary role of 18F-FDG and 11C-MET for the study of brain tumors and favors their use for stereotactic PET guidance of diagnostic or therapeutic procedures.

In order to launch a new transplantation program for Parkinson's disease (PD), we evaluated the safety and efficacy of fetal ventral mesencephalic grafts in 3 patients with advanced PD. Inclusion criteria and clinical evaluation followed strictly the Core Assessment Program for Intracerebral Transplantation. The transplantation procedure was based on the technique previously described by the groups in Lund (Sweden) and Créteil (France). The putamen contralateral to the site of predominant symptoms was unilaterally grafted in all patients. Magnetic resonance (MR)-based stereotactic guidance with multiplanar correlation was used to define 3 implantation trajectories in the precommissural, commissural, and postcommissural putamen. Fetal ventral mesencephalon was prepared from 6- to 8-week-old human embryos obtained from same-day abortions. Under general anesthesia, 8 deposits of 3 microliters of the fetal tissue were placed 1 mm apart along each implantation trajectory using a customized microsyringe and needle attached to the stereotactic frame. The patients recovered uneventfully from the neurosurgical procedure. Early postoperative MR clearly showed the implantation trajectories reaching the putamen in all patients. The follow-up period was of 12, 9 and 6 months, for each of the 3 patients, respectively. Clinical changes appeared between 3 and 6 months after transplantation and consisted of an increase in the 'on' periods and in quantitative bilateral improvement in the motor timed tests. There was an improvement of the Unified Parkinson's Disease Rating Scale score and an improvement of rigidity. Tremor was unchanged, and there was a slight and transient increase in dyskinesias. Neuropsychological follow-up revealed slight frontal alterations in 2 patients. Positron emission tomography demonstrated an increase of 18F-fluorodopa uptake in the grafted site. Adverse events include a reversible Cushing syndrome secondary to immunosuppression in 1 patient and a transient episode of confusion in another. The results of this study, designed as a prerequisite for a wider transplantation program, are in accordance with those previously reported by others and show that, using standardized neurosurgical techniques and methods of evaluation, transplantation is a reproducible and safe therapeutic approach which provides clinical benefits to patients with advanced PD.

Three patients were examined using PET with L-methyl-11C-methionine (11C-methionine) and 2-18F-fluoro-2-deoxy-D-glucose (FDG) 20 to 32 days after the occurrence of nontumoral brain hematomas. PET revealed high uptake of 11C-methionine in the area surrounding the hematoma in all three patients. In two patients, discrete spots of moderate uptake of FDG were found at the periphery of a hypometabolic area. PET studies were repeated in two patients 76 and 103 days after the bleeding, respectively, and showed a dramatic decrease in 11C-methionine uptake around the hematoma. The spots of FDG uptake disappeared on the repeated late scans. We hypothesize that the subacute gliotic reaction surrounding brain hematomas is responsible for increased uptake of 11C-methionine and for the presence of spots of FDG uptake. PET studies with 11C-methionine and FDG performed 20 to 32 days after the initial symptom are not helpful in the differentiation between neoplastic and non-neoplastic origins of an intracerebral hemorrhage since tracer uptake at the periphery of the lesion may be increased in both.

Results: A semiquantitative analysis revealed a significant regional correlation between C-11-MET and F-18-FDG uptakes. Uptake of both tracers was significantly higher on the site of tumor samples showing anaplastic changes than in the rest of the tumor. Presence of necrosis in anaplastic areas of the tumor significantly reduced the uptake of C-11-MET, Conclusion: PET with C-11-MET and F-18-FDG may help to evaluate, in vivo, the metabolic heterogeneity of human gliomas, Anaplasia is a factor of increased uptake of both tracers, but microscopic necrosis in anaplastic areas influences their uptake differently, This finding probably relates to the differences in tracer uptake by non-neoplastic components of necrotic tumors.

- Abstract
Concentrations of major catabolites of dopamine were followed in the ventricular cerebrospinal fluid (CSF) in five patients undergoing intracranial pressure monitoring for chronic hydrocephalus. Determinations were made every 2 h following the administration of carbidopa/levodopa 25/250 mg (one Sinemet capsule) given 8 h apart. The rise of homovanillic acid (HVA) concentrations was slow and progressive, reaching the level of statistical significance (p < or = 0.01) only 8 h after the second administration of Sinemet. The rise in 3,4-dihydroxyphenylacetic acid (DOPAC) was faster than the rise in HVA, with the peak value detected 4 h after the first administration of Sinemet. These data are interpreted as a confirmation, in humans, of a slow pool of exogenous levodopa, previously demonstrated in animal studies.

- Abstract
Background: Safinamide is a recent multimodal antiparkinsonian drug that inhibits monoamine oxidase B and modulates the glutamatergic system with positive effects on motor and nonmotor symptoms of Parkinson's disease (PD). This post-hoc analysis of the European SYNAPSES study provides first-time data on the use of safinamide in routine clinical practice in Belgium., Objective: To describe the efficacy and safety of safinamide in Belgian PD patients in real-life conditions., Methods: Post-hoc analysis of the Belgian cohort from the European SYNAPSES trial, which was an observational, multicenter, retrospective-prospective cohort study. Patients were followed up to 12 months. Analyses were performed in the overall population and according to different criteria such as the age limit (> 75 years), presence or absence of relevant comorbidities, presence or absence of psychiatric conditions such as depression and anxiety, patients on levodopa monotherapy or levodopa in combination with other treatments, patients on rasagiline before inclusion or not., Results: Of the 172 patients included, 29.2% were > 75 years, 58.9% had relevant comorbidities and 32.7% had psychiatric conditions. Almost all the patients reported motor (98.8%) or non-motor (86.3%) symptoms. During the study, 36.3% of patients reported drug-related reactions. The adverse drug reactions were those already described in the patients' information leaflet. The majority were mild or moderate and completely resolved and no differences were detected between the subgroups of patients. Almost 35% of the patients demonstrated a clinically significant improvement in the UPDRS and 50% of the patients with wearing-off at baseline, did not report wearing-off anymore after one year of treatment. Patients under levodopa monotherapy compared to patients receiving levodopa combined with other antiparkinsonian treatments benefit more from safinamide treatment. Patients switched from rasagiline to safinamide seemed also to benefit more from safinamide treatment., Conclusion: The study confirms the excellent safety and efficacy profile of safinamide, particularly in more vulnerable groups of patients such as the elderly and patients with significant comorbidities or psychiatric conditions such as depression or anxiety., (© 2022.

- Abstract
Introduction: Intraoperative microelectrodes recording with the Ben Gun microdrive system are often used during DBS surgery. An accurate location of these microelectrodes will directly influence the interest of this recording. We have studied the imprecision of implantation of these microelectrodes., Methods: We have analyzed the stereotactic position of 135 microelectrodes implanted with the Ben Gun microdrive during DBS surgery of 16 patients with advanced Parkinson's disease. An intracranial CT was obtained and integrated to a stereotactic planification system. We recorded the stereotactic coordinates of the 5 microelectrodes inserted simultaneously in a cross-shape. The coordinates of each microelectrode were compared with coordinates of the other 4 electrodes inserted simultaneously with the Ben Gun and visible on the same iCT image. Thus, this procedure avoids errors from image fusion and from brain shift. We calculate (1) the three-dimensional Euclidian deviation of microelectrodes, (2) the deviation in X- and Y-axes on reconstructed probe's eye view MR images, and (3) the deviation from the 2-mm theoretical distance between the central electrode and 4 satellite microelectrodes., Results: The median deviation was 0.64 mm in 3-D and 0.58 mm in 2-D probe's eye view. Satellite electrodes were located from the central electrode theoretically at 2.0 mm and practically within the range 1.9-2.1 mm, 1.5-2.5 mm, 1.0-3.0 mm, and 0.5-3.5 mm for, respectively, 9.3%, 53.7%, 88.0%, and 98.1%, thus highlighting the significant deviation from the theoretical distance. Position imprecisions were similar for the 4 satellite microelectrodes. The imprecision was similar in X-axis and Y-axes and statistically less in Z-axis. For bilateral implantation, the second implantation of the same patient was not associated with a greater risk of deviation of the microelectrodes than for the first side implanted., Conclusion: A significant percentage of microelectrodes for MER can deviate substantially from their theoretical target during DBS procedures. An iCT can be used to estimate the potential deviation of microelectrodes and improve the interpretation of MER during the procedure., (© 2023 S. Karger AG, Basel.)

- Abstract
Parkinson's disease in a neurodegenerative disorder that affects as many as 1-2 % of persons aged 60 years and older. Parkinson's disease occurs infrequently under 40 years of age, with major genetic implication. Alpha-synuclein plays significant pathogenic role in Parkinson's disease. Therapeutic advances based on a synucleinrelated mechanism are now developed : immunotherapy against alpha-synuclein for example. The diagnosis of Parkinson's disease remains mostly clinical. DatScan® may be helpful to distinguish parkinsonian syndrome and essential tremor. Current therapy is mainly based on a dopamine replacement strategy using the precursor levodopa (L-Dopa) and dopamine receptor agonists. Parkinson's is also associated with non-motor symptoms like sleep disorders, autonomic symptoms, neuropsychiatric symptoms. Advanced disease is associated with emergence of feature such as freezing, falling and neuropsychological dysfunction. Nonpharmacologic treatments like exercise are fundamental elements of patients' management. Motor complications and dyskinesia are common in advanced Parkinson's disease. Continuous administration of L-Dopa/carbidopa infusion in the jejunum provides more continuous dopaminergic drug delivery and stimulation and reduce motor complications. Further other approach are developped like surgical procedures: ex : high frequency stimulation of subthalamic nucleus, the more rational target for stimulation in Parkinson's disease.

- Abstract
Thrombotic thrombocytopenic purpura (TTP) is a hematologic disease involving the platelet aggregation and resulting in hemolytic anemia, thrombocytopenia, and microvascular occlusion. Although frequent neurologic features are headache and confusion, focal deficit is described in 30% of the cases. There are a lot of causes inducing thrombotic thrombocytopenic, but reports are lacking when associated with Grave disease. We describe the case of a 51-year-old Caucasian woman presenting a 24-hour story of sudden onset of dysarthria and left superior limb palsy. Four months before, she developed severe hyperthyroidism associated with petechiae, hemolytic anemia, thrombocytopenia, and schistocytes at blood film examination. Relapse of TTP in association with Grave disease was diagnosed. There are few reports describing association between Grave disease and TTP with only mild neurologic involvement. We described, to our knowledge, the first case of acute ischemic stroke secondary to thrombotic thrombocytopenic induced by thyrotoxicosis., (Copyright © 2014 National Stroke Association.

- Abstract
Data concerning efficacy, safety, and patient satisfaction of levodopa/carbidopa intestinal gel (LCIG, Duodopa, AbbVie, Wavre, Belgium) infusion in routine clinical practice were needed to maintain reimbursement of the drug in Belgium. Patients with advanced Parkinson's disease in 27 neurology centers across Belgium were included. Of 100 patients who underwent naso-intestinal (NI) evaluation with LCIG, 67 received permanent treatment with LCIG via percutaneous endoscopic gastrostomy and jejunal tube (PEG/J). Efficacy was evaluated at baseline (on levodopa) and during a follow-up (FU) visit (on LCIG) using the Unified Parkinson's Disease Rating Scale (UPDRS) IV. Patient appraisal of the Duodopa system was evaluated using a visual analog scale for therapy compliance, user-friendliness, and global appreciation. Safety was assessed by reporting suspected adverse drug reactions (ADRs) and medical device-related complaints. FU evaluations were conducted in 37 patients. Significant improvement at FU was observed for motor complications (UPDRS IV) as the mean change from baseline to FU was -6.3 (95 % CI -8.1 to -4.5). Patient appraisal showed high scores for hospital delivery, user-friendliness, and patient global appreciation, as well as family appreciation of the system on daily life. Few ADRs and system malfunctions were reported, with no unexpected ADRs. In conclusion, the symptoms and impact of Parkinsonism improved markedly when LCIG PEG/J was initiated.

- Abstract
Objective: In the Belgian Fabry Study (BeFaS), the prevalence of Fabry disease was assessed in 1000 young patients presenting with stroke, unexplained white matter lesions or vertebrobasilar dolichoectasia. The results of the BeFaS suggested that Fabry disease may play a role in up to 1% of young patients presenting with cerebrovascular disease. However, the clinical relevance was unclear in all cases. We report on detailed phenotyping in subjects identified with α-galactosidase A (α-Gal A) enzyme deficiency or GLA mutations identified in the BeFaS (n=10), and on the results of family screening in this population., Methods: Family screening was performed to identify additional mutation carriers. Biochemical and/or clinical evaluation of all subjects (BeFaS index patients and relatives carrying a GLA mutation) was performed., Results: Genetic family screening revealed 18 additional GLA mutation carriers. Bloodspot α-Gal A enzyme activity was normal in all GLA mutation carriers, even in 2 males with the p.A143T mutation. Plasma Gb3 and lyso-Gb3 levels were normal in all subjects. Elevated Gb3 in urine was detected in 2 subjects. Some classic clinical signs of Fabry disease, like angiokeratoma or cornea verticillata, could not be detected in our population. Cardiac symptoms of Fabry disease were found in 6 out of 10 p.A143T carriers. No signs of cerebrovascular disease were found in the relatives with a GLA mutation., Conclusions: We could not identify mutations causing the classical clinical phenotype of Fabry disease in our cerebrovascular disease population. Enzyme activity analysis in bloodspots and plasma may fail to identify late-onset variants of Fabry disease. We recommend genetic testing when an atypical, late-onset variant of Fabry disease is suspected in a male cerebrovascular disease patient. However, this may lead to the identification of non-disease causing or controversial genetic variants., (Copyright © 2012 Elsevier B.V. All rights reserved.)

- Abstract
Objectives: I-123 ioflupane (FP-CIT) single-photon emission computed tomography is a recognized tool in the diagnosis of Parkinsonian syndromes. In practice, data interpretation relies on visual and semiquantitative analyses. Good interobserver reproducibility is a prerequisite before claiming the robustness of a technique. This study aimed at evaluating interobserver reproducibility of this approach., Methods: Thirty nuclear medicine physicians participated in the study. Data included FP-CIT images and semiquantitative measurements of 12 cases, covering a wide spectrum of scintigraphic patterns and for which a 'true' clinical diagnosis based on long-term follow-up was available. Interobserver agreement was defined, for each case, as the highest percentage reached among the three proposed answers with complete agreement arbitrarily set at 80% or more. Variability in an individual observer's sensitivity to assess data as normal, equivocal or abnormal was scored using a three-point scale., Results: Response rate was 99.7%. Among the three possible answers,'normal' accounted for 41.2% of the total, 'abnormal' for 49.8% and 'equivocal' for 8.1%. The mean interobserver agreement was 76% (range: 37-100%), with complete agreement being reached only in five cases. The interpretation proposed by most observers accorded to clinical diagnosis in 75% of the cases. Abnormalities of the central nervous system were encountered in all the cases with disagreement between the observer's interpretation and clinical diagnoses. An important variability in the observers' sensitivity was seen., Conclusion: In the particular setting of this preliminary study evaluating the reproducibility of FP-CIT single-photon emission computed tomography interpretation in a group of nuclear medicine physicians with various experiences, interobserver agreement was suboptimal. Collegial discussion and standardized interpretation criteria could contribute to an improved reproducibility.

- Abstract
Objectives: To evaluate whether dopamine transport system imaging by FP-CIT single-photon emission computed tomography (SPECT) can be helpful to differentiate idiopathic Parkinson's disease (IPD) from secondary Parkinsonism induced by amiodarone., Methods: Twenty-two patients with Parkinsonism during amiodarone therapy were evaluated by clinical neurological examination and FP-CIT SPECT. Thereafter, amiodarone was discontinued whenever possible and antiparkinsonian treatment was modified, if required. Clinical neurological status was reevaluated within a year of the SPECT examination., Results: At baseline, clinical neurological examination was quite similar in all patients. No clinical symptom was able to clearly orientate the diagnosis toward IPD or drug-induced Parkinsonism. Using SPECT, the number of normal and abnormal patients was evenly distributed. In the abnormal SPECT group, amiodarone was modified in seven patients of whom six improved at follow-up. Antiparkinsonian treatment had been modified in all the patients. In the four cases with no amiodarone changes, clinical improvement was noted if antiparkinsonian treatment was optimized (three patients). In the 11 normal SPECT patients, amiodarone was modified in five patients. All patients ameliorated (two) or even normalized (three). In the six patients with normal SPECT in whom amiodarone had not been modified, symptoms remained stable despite the absence of antiparkinsonian treatment., Conclusion: In patients treated with amiodarone, IPD is sometimes clinically difficult to differentiate from drug-induced Parkinsonism. Using FP-CIT, a normal scan suggests drug-induced Parkinsonism, hence, there is no need for antiparkinsonian treatment and all possible attempts to reduce or preferably stop amiodarone. An abnormal scan, on the other hand, indicates IPD. In this case, treating IPD seems to have more impact on motor changes than modifying the antiarrhythmic drug.

- Abstract
The diagnosis of idiopathic Parkinson's disease (IPD) remains mostly clinical. Nevertheless, differentiating IPD from essential tremor or other parkinsonian syndromes solely by clinical examination can be challenging in some cases, especially in the early stage of the disease. The introduction of new isotopic functional imaging techniques, and more specifically the labelling of dopamine transporter derivatives, has improved the understanding and early detection of some diseases affecting the basal ganglia. Iodine-123-FP-CIT (DaTSCAN), a (presynaptic) dopamine transporter analogue for nuclear medicine imaging, has recently been introduced for the non-invasive differential diagnosis between IPD and essential tremor or secondary (e.g. drug-related) parkinsonian syndromes. DaTSCAN scintigraphy has also demonstrated some usefulness in the evaluation of other neurodegenerative parkinsonian syndromes such as Lewy-body dementia or multiple system atrophy. For this latter however, the DaTSCAN has to be combined with a second scintigraphy, imaging the post-synaptic dopaminergic receptors, such as the D2-ligand 123I-iodobenzamide. Combining DaTSCAN scintigraphy to a functional study of the brain cortical activity using a brain perfusion scintigraphy or to the evaluation of the cardiac adrenergic system by means of a myocardial MIBG scintigraphy (a norepinephrine storage analogue) can also be helpful to refine the diagnosis. Our experience shows that a good collaboration between the neurologist specialized in movement disorders and the nuclear medicine physician is useful, if not mandatory, to optimize the diagnostic performances of DaTSCAN scintigraphy.

- Abstract
We describe a 52-year-old woman presenting a 2-year history of limb clumsiness and gait difficulties, characterized by progressive worsening. Neurological examination revealed cerebellar intention tremor, cerebellar dysmetria of all 4 limbs and ataxic gait. However, brain MRI was normal. Analysis of fast wrist flexion movements demonstrated hypometric movements, with decreased intensities of agonist EMG activities and increased durations of antagonist EMG activities. Such EMG abnormalities have been demonstrated in patients presenting lesions of the middle cerebellar peduncle, affecting the crossed cerebellopontine projections. Moreover, adaptation motor learning during a pinch task (isometric force) showed a severe inability to adapt motor programming, indicating a disruption of cerebellolivary and cerebellopontine afferent systems. We suggest that our patient presented an exceptional brainstem syndrome involving the function of cerebellar inflow tracts. Such electrophysiological findings are not encountered in patients presenting a cerebellar cortical degeneration or cerebellovlivopontine atrophy, and might have important implications in the treatment of cerebellar ataxia in the future.

- Abstract
We investigated, by positron emission tomography (PET) with [18F]fluoro-2-deoxy-d-glucose (FDG) (FDG-PET), brain glucose metabolism in 19 patients with parkinsonian features. We compared local pattern of FDG uptake and asymmetry indexes in patients with therapeutic response to levodopa (L-dopa) (group 1, presumed Parkinson's disease, n = 9) and patients without L-dopa therapeutic response (group 2, presumed striatonigral degeneration, n = 10). Limb dystonia was present in 11% of patients in group 1 and in 40% of patients in group 2. Asymmetry in basal ganglia metabolism was distributed differently in the two groups (analysis of variance, p < 0.04). In superior and inferior putamen, superior and middle caudate, ventral striatum, and inferior thalamus, relative reduction in metabolism on the side contralateral to predominant parkinsonian signs was associated with L-dopa unresponsiveness. On the contrary, in middle caudate, ventral striatum, and inferior thalamus, a relative increase in metabolism on the side contralateral to the predominant side, parkinsonian signs were found in L-dopa-responsive patients. Our FDG-PET study using simple statistical procedures demonstrates inverse asymmetry of basal ganglia glucose metabolism in parkinsonian patients grouped on the sole basis of L-dopa responsiveness.

- Abstract
Unlabelled: Gliomas are regionally heterogeneous tumors. The local relationship between histologic features and radiotracer uptake evaluated by PET should therefore influence analysis and interpretation of PET results on gliomas. This study explored this local relationship as a result of PET guidance of stereotactic biopsies., Methods: Local histology was confronted to the regional uptake of 18F-2-fluoro-2-deoxy-D-glucose (18F-FDG) and 11C-methionine (11C-MET) in 14 patients with high-grade glioma diagnosed during a procedure of PET-guided stereotactic biopsies. We analyzed the uptake of both tracers in regions of interest centered on the stereotactic coordinates of 93 biopsy samples., Results: A semiquantitative analysis revealed a significant regional correlation between 11C-MET and 18F-FDG uptakes. Uptake of both tracers was significantly higher on the site of tumor samples showing anaplastic changes than in the rest of the tumor. Presence of necrosis in anaplastic areas of the tumor significantly reduced the uptake of 11C-MET., Conclusion: PET with 11C-MET and 18F-FDG may help to evaluate, in vivo, the metabolic heterogeneity of human gliomas. Anaplasia is a factor of increased uptake of both tracers, but microscopic necrosis in anaplastic areas influences their uptake differently. This finding probably relates to the differences in tracer uptake by non-neoplastic components of necrotic tumors. These results underline the complementary role of 18F-FDG and 11C-MET for the study of brain tumors and favors their use for stereotactic PET guidance of diagnostic or therapeutic procedures.

- Abstract
We used in vitro microdialysis-HPLC to determine L-3,4-dihydroxyphenylalanine (L-DOPA) and its metabolites in plasma of patients with advanced Parkinson disease. Blood samples and clinical evaluations were obtained 0, 30, 60, 90, 120, and 150 min after oral administration of carbidopa/L-DOPA (25/100 mg, 12.5/125 mg, and 50/200 mg). In vitro recoveries for L-DOPA and metabolites ranged from 22% to 36%. Linear correlation was found between metabolite concentrations in the dialysate and in the surrounding medium. There was a significant positive correlation between L-DOPA dose and plasma concentration of L-DOPA and homovanillic acid (P < 0.04). Clinical response was maximum 60 min after L-DOPA administration. Threshold L-DOPA plasma concentration averaged 7.74 +/- 3.3 mumol/L. Motor effect is longer with the highest L-DOPA peak concentration (P < 0.01). Microdialysis-HPLC is readily applicable, reproducible, and allows monitoring of plasma L-DOPA and metabolites in parkinsonian patients.

- Abstract
In order to launch a new transplantation program for Parkinson's disease (PD), we evaluated the safety and efficacy of fetal ventral mesencephalic grafts in 3 patients with advanced PD. Inclusion criteria and clinical evaluation followed strictly the Core Assessment Program for Intracerebral Transplantation. The transplantation procedure was based on the technique previously described by the groups in Lund (Sweden) and Créteil (France). The putamen contralateral to the site of predominant symptoms was unilaterally grafted in all patients. Magnetic resonance (MR)-based stereotactic guidance with multiplanar correlation was used to define 3 implantation trajectories in the precommissural, commissural, and postcommissural putamen. Fetal ventral mesencephalon was prepared from 6- to 8-week-old human embryos obtained from same-day abortions. Under general anesthesia, 8 deposits of 3 microliters of the fetal tissue were placed 1 mm apart along each implantation trajectory using a customized microsyringe and needle attached to the stereotactic frame. The patients recovered uneventfully from the neurosurgical procedure. Early postoperative MR clearly showed the implantation trajectories reaching the putamen in all patients. The follow-up period was of 12, 9 and 6 months, for each of the 3 patients, respectively. Clinical changes appeared between 3 and 6 months after transplantation and consisted of an increase in the 'on' periods and in quantitative bilateral improvement in the motor timed tests. There was an improvement of the Unified Parkinson's Disease Rating Scale score and an improvement of rigidity. Tremor was unchanged, and there was a slight and transient increase in dyskinesias. Neuropsychological follow-up revealed slight frontal alterations in 2 patients. Positron emission tomography demonstrated an increase of 18F-fluorodopa uptake in the grafted site. Adverse events include a reversible Cushing syndrome secondary to immunosuppression in 1 patient and a transient episode of confusion in another. The results of this study, designed as a prerequisite for a wider transplantation program, are in accordance with those previously reported by others and show that, using standardized neurosurgical techniques and methods of evaluation, transplantation is a reproducible and safe therapeutic approach which provides clinical benefits to patients with advanced PD.

- Abstract
Positron emission tomography (PET) with 18F-fluoro-2-deoxy-D-glucose (FDG) is frequently used to study the metabolic correlates of movement and mental disorders. These studies generally focus on changes in the frontal cortex and the basal ganglia. The reproducibility of glucose metabolism estimates in these structures was tested in 13 normal subjects studied at rest using a standard and simple protocol. A reproducible dorsoventral metabolic gradient was demonstrated in the frontal cortex. Such a gradient was not present in the basal ganglia when the upper region of interest in the caudate nucleus, where the lower metabolic rate of glucose was probably attributable to partial volume effects, was not considered. Absolute values of glucose metabolic rates varied by 6.4 to 12.5% in the frontal cortex and by 6.8 to 14.7% in the basal ganglia. Variations in normalized values in the basal ganglia ranged from 4.0 to 8.6%. The number of subjects required to detect statistical differences in group comparison or in test-retest studies was calculated for different anticipated levels of change. With the variability detected in this experiment, less than 10 subjects were expected to be sufficient to detect a 15% change in most regions and in both types of studies.

- Abstract
In the presence of carbidopa, L-3,4-dihydroxy-6-[18F]fluorophenylalanine ([18F]fluoro-DOPA) is mainly metabolized by catechol-O-methyl transferase. We studied the effects of entacapone, a peripheral catechol-O-methyl transferase inhibitor, on striatal [18F]fluoro-DOPA uptake in rats. Rats were pretreated with carbidopa, entacapone or both before high specific activity (> 2 Ci/mmol) [18F]fluoro-DOPA administration. Entacapone alone antagonized the appearance of methylated metabolites in plasma, striatum and cerebellum but did not increase striatal [18F]fluoro-DOPA availability. Entacapone added to carbidopa significantly increased the striatum/cerebellum total radioactivity ratio (1.4 versus 1.2 in rats with carbidopa, 1.0 in controls) but significant levels of methylated metabolites were found in the brain. Entacapone added to carbidopa might increase the striatum/cerebellum total radioactivity ratio in humans undergoing [18F]fluoro-DOPA positron emission tomography (PET) studies. However, the appearance of methylated metabolites in the brain could hamper quantification of the PET data.
