Functional chest pain: nociception and visceral hyperalgesia.
TLDR
The focus of this review is to explore the evolving research and clinical approaches with a particular emphasis on the sensory or afferent neuronal dysfunction of the esophagus as a key player in the manifestation of functional chest pain syndrome.
Adenosine modulates oesophageal sensorimotor function in humans
TLDR
Adenosine modulates oesophageal sensorimotor function and may play a role in the pathogenesis of functional chest pain.
Somatostatin inhibits the ventilatory response to hypoxia in humans.
TLDR
The results show an hitherto-unsuspected inhibitory potential of this neuropeptide on the control of breathing; the sparing of the hypercapnic response is suggestive of an action on the carotid body but does not exclude a central effect.
Cardiovascular reflex responses to ischemia during occlusion of celiac and/or superior mesenteric arteries.
TLDR
The data suggest that the larger cardiovascular reflex produced by SMA occlusions compared with celiac occlusion may be related to a greater increase of lactic acid concentration in tissue supplied by the SMA.
Bradykinin BK2 receptors contribute to reflex cardiovascular responses during brief abdominal ischemia.
TLDR
Results indicate that the stimulation of BK2 receptors on visceral afferent nerves by BK is responsible, at least in part, for the reflex cardiovascular response during visceral ischemia.
Role of spinal NMDA and non-NMDA receptors in the pressor reflex response to abdominal ischemia.
TLDR
The combined data suggest that spinal NMDA and AMPA receptors play a role in the abdominal ischemia pressor reflex.
Barostat or dynamic balloon distention test: which technique is best suited for esophageal sensory testing?
TLDR
DBD was better tolerated than BBD for evaluation of esophageal sensation and provided comparable data on biomechanical properties, hence, it is recommended to recommend DBD for performing esphageal balloon distension test.
Reflex cardiovascular response to brief abdominal visceral ischemia is mediated in part by prostaglandins.
Prostaglandin concentrations are elevated in intestinal lymph during brief abdominal visceral ischemia, and exogenously applied prostaglandins can directly stimulate or sensitize ischemically
Bradykinin BK2 receptors contribute to reflex cardiovascular responses during brief abdominal ischemia.
TLDR
Results indicate that the stimulation of BK2 receptors on visceral afferent nerves by BK is responsible, at least in part, for the reflex cardiovascular response during visceral ischemia.
Hemothorax after percutaneous liver biopsy: an unusual complication
TLDR
This study demonstrates that the elevation in total amylase sometimes observed in celiac disease is actually related to the presence of macroamylasemia, which has not previously been quantified.
