The pancreas is a major player in nutrient digestion. In chronic pancreatitis both exocrine and endocrine insufficiency may develop leading to malnutrition over time. Maldigestion is often a late complication of chronic pancreatic and depends on the severity of the underlying disease. The severity of malnutrition is correlated with two major factors: (1)(More)
Opioids are the most commonly prescribed medications to treat severe pain in the Western world. It has been estimated that up to 90% of American patients presenting to specialized pain centres are treated with opioids. Along with their analgesic properties, opioids have the potential to produce substantial side effects, such as nausea, cognitive impairment,(More)
BACKGROUND Pregabalin has a broad spectrum of analgesic and antihyperalgesic activity in both basic and clinical studies. However, its mechanisms and sites of action have yet to be determined in humans. AIMS To assess the antinociceptive effect of pregabalin on experimental gut pain in patients with visceral hyperalgesia due to chronic pancreatitis and to(More)
Painful sensations from the gastrointestinal (GI) tract are common symptoms in the clinic but the etiology is often not fully understood and underlying diseases can be difficult to diagnose and treat successfully. In clinical practice, GI pain is often diffuse and pain referral to somatic structures can be the presenting symptom. In addition, concomitant(More)
Previous methods for visceral thermal stimulation have lacked control of the temperature rate and visual inspection of the organ. The aims of this study was to develop a method for linear control of heat stimulation in the human oesophagus combined with endoscopy, to assess the reproducibility of this method and to investigate sensitivity to thermal(More)
OBJECTIVE Conditioning Pain Modulation (CPM) represents the various descending inhibitory mechanisms induced by a heterotopic noxious stimulation (previously termed DNIC). CPM-induced modulations in brain activity have not previously been investigated to visceral pain. Hence the aims were to assess the role of CPM in terms of: (1) psychophysics, (2)(More)
BACKGROUND & AIMS Patients with painful chronic pancreatitis (CP) might have abnormal brain function. We assessed cortical thickness in brain areas involved in visceral pain processing. METHODS We analyzed brain morphologies of 19 patients with painful CP and compared them with 15 healthy individuals (controls) by using a 3T magnetic resonance scanner. By(More)
BACKGROUND Intense abdominal pain is the dominant feature of chronic pancreatitis. During the disease changes in central pain processing, e.g. central sensitization manifest as spreading hyperalgesia, can result from ongoing nociceptive input. The aim of the present study is to evaluate the effect of pregabalin on pain processing in chronic pancreatitis as(More)
BACKGROUND/OBJECTIVES Chronic pancreatitis (CP) is a disabling disease characterised by abdominal pain, and various pancreatic and extra-pancreatic complications. We investigated the interactions between pain characteristics (i.e. pain severity and its pattern in time), complications, and quality of life (QOL) in patients with CP. METHODS This was a(More)
OBJECTIVE In patients with painful chronic pancreatitis (CP) there is increasing evidence of abnormal pain processing in the central nervous system. Using magnetic resonance (MR) diffusion tensor imaging, brain microstructure in areas involved in processing of visceral pain was characterised and these findings were correlated to clinical pain scores.
