BACKGROUND The presence of Lewy bodies and Lewy neurites (LN) has been demonstrated in the enteric nervous system (ENS) of Parkinson's disease (PD) patients. The aims of the present research were to use routine colonoscopy biopsies (1) to analyze, in depth, enteric pathology throughout the colonic submucosal plexus (SMP), and (2) to correlate the(More)
Emerging evidences suggest that the enteric nervous system (ENS) is affected by the degenerative process in Parkinson's disease (PD). In addition lesions in the ENS could be associated with gastrointestinal (GI) dysfunctions, in particular constipation, observed in PD. However, the precise alterations of the ENS and especially the changes in the(More)
BACKGROUND The treatment of gastroparesis remains unsatisfactory despite prokinetic and anti-emetic drugs. Gastric electrical stimulation has been proposed as a therapeutic option. We have assessed the effect of gastric electrical stimulation on symptoms, medical treatment, body weight and gastric emptying in patients with intractable symptomatic(More)
Parkinson's disease is the second most common neurodegenerative disease after Alzheimer's disease. It has been classically considered that the pathological hallmarks of Parkinson's disease, namely Lewy bodies and Lewy neurites, affect primarily the substantia nigra. Nevertheless, it has become increasingly evident in recent years that Parkinson's disease is(More)
Lewy pathology affects the gastrointestinal tract in Parkinson's disease (PD) and data from recent genetic studies suggest a link between PD and gut inflammation. We therefore undertook the present survey to investigate whether gastrointestinal inflammation occurs in PD patients. Nineteen PD patients and 14 age-matched healthy controls were included. For(More)
Lewy pathology in Parkinson disease (PD) extends well beyond the CNS, also affecting peripheral autonomic neuronal circuits, especially the enteric nervous system (ENS). The ENS is an integrative neuronal network also referred to as "the brain in the gut" because of its similarities to the CNS. We have recently shown that the ENS can be readily analyzed(More)
The major functions of the stomach are under the control of the enteric nervous system (ENS), but the neuronal circuits involved in this control are largely unknown in humans. Enteric neurones can be characterized by their neuromediator or marker content, i.e. by neurochemical coding. The purpose of this study was to characterize the presence and(More)

BACKGROUND/AIMS To investigate whether transit time could influence H2 consuming flora and certain indices of colonic bacterial fermentation. METHODS Eight healthy volunteers (four methane excretors and four non-methane excretors) were studied for three, three week periods during which they received a controlled diet alone (control period), and then the(More)
BACKGROUND To evaluate the safety and clinical efficacy of botulinum toxin (BT) in patients with achalasia followed up for six months. METHODS Fifty five symptomatic patients with manometrically proven achalasia were included in a multicentre prospective trial. Before and two weeks and two months after intrasphincteric injection of BT, symptoms of(More)
BACKGROUND Recent studies indicate that gastric emptying may be influenced by patterns of previous nutrient intake. Endogenous cholecystokinin (CCK), whose synthesis and release can be affected by dietary intake, has a major role in the regulation of gastric emptying. AIMS To evaluate the influence of diets with differing protein content on gastric(More)
