Sex differences in responsiveness to painful and non-painful stimuli are dependent upon the stimulation method.
Sex differences in thermo- and electrocutaneous responsiveness to painful and non-painful stimuli were investigated in 20 women and 20 men. Heat pain, warmth, and cold thresholds were assessed on the hand and foot with a Peltier thermode system. In addition, subjects used magnitude estimation to judge the sensation intensity evoked by temperatures ranging from 38 degrees C to 48 degrees C appli...
متن کاملPainful cutaneous laser stimuli induce event-related gamma-band activity in the lateral thalamus of humans.
Although the thalamus is an important module in "pain networks," there are few studies of the effect of experimental pain upon thalamic oscillations. We have now examined the hypothesis that, during a series of painful cutaneous laser stimuli, thalamic signals will show stimulus-related gamma-band spectral activity, which is modulated by attention to vs. distraction from the painful stimulus. W...
متن کاملThe responses to painful stimuli of patients with severe chronic painful conditions.
In the study of patients who have severe and prolonged, chronic, painful conditions, it is a clinical fact that some will react more profoundly than others to what are apparently similar conditions. It is also obvious clinically that pain is an extreme fearand anxiety-provoking stimulus. Furthermore, the diagnosis of "functional pain," or of a "functional element" in pain, is one frequently att...
متن کاملDiffuse Optical Tomography Activation in the Somatosensory Cortex: Specific Activation by Painful vs. Non-Painful Thermal Stimuli
BACKGROUND Pain is difficult to assess due to the subjective nature of self-reporting. The lack of objective measures of pain has hampered the development of new treatments as well as the evaluation of current ones. Functional MRI studies of pain have begun to delineate potential brain response signatures that could be used as objective read-outs of pain. Using Diffuse Optical Tomography (DOT),...
متن کاملPainful peripheral neuropathy associated with voriconazole use.
BACKGROUND Voriconazole is a new antifungal agent that has been recently introduced into clinical practice. We found no published reports of painful peripheral neuropathy associated with its use. OBJECTIVE To describe a unique case of painful peripheral neuropathy associated with voriconazole use. SETTING University hospital. PATIENT A 43-year-old patient who had undergone liver transplan...
